Update for the Week of August 4, 2014

The most significant insect event in the past week was the reports of plant bug tolerance to all labeled or recommended insecticides in the Tennessee Valley of North Alabama. Several of our most experienced consultants are reporting that all classes of chemistry are suppressing plant bugs but their presence and damage behind applications are still above threshold levels. This has required repeated sprays and now tank mixtures with two recommended insecticides. Under these conditions, input costs for cotton insects, particularly plant bugs, make cotton an unattractive crop option going into the 2015 season. Some areas of the mid-south have been dealing with this problem for several years. At this point, the Alabama situation appears to be confined to the Tennessee Valley area.

It has been my experience that once plant bugs get embedded in rank cotton in July, they have always been difficult to control, requiring multiple applications. So now, we have insecticide tolerance in addition to a coverage issue. Looking ahead I see a larger role for the IGR Diamond during the early bloom period in future years.

Now to a quick oversight of other insect problems on cotton and other crops; stink bugs, primarily brown, are requiring controls in some cotton fields. However, overall they are not as heavy and widespread as expected. Aphids are showing back up in some fields requiring controls. Spider mites are present in many fields. It seems like we get more calls about mite control following weeks of high temperature and dry conditions.

In soybeans we are beginning to see loopers as far north as Montgomery in older beans. So far they are only at about a third of a threshold level. Scouts are reporting an occasional corn earworm and velvetbean caterpillar in the soybean mix. The same holds true for peanuts.

Fall armyworms (grass strain) are on about every crop except cotton now. Hay, grasses, peanuts, soybeans are all experiencing the need for repeated applications for FAW. We could safely say that FAW’s have about worn out their welcome, even though they are easy to control. It seems like their preferred row crop is soybeans planted in wheat stubble. Some fields are now on their third infestation and replanting has been required due to near 100% defoliation.

In many ways, 2014 has been like “old times” to Extension entomologists with numerous phone calls about when to treat and what chemical to choose. We don’t feel like step-children to the weed resistance and disease issues this season.

Scouting crops is the first step in all insect management and control programs.

Updates from June 20, 2014

• Several more reports from diverse areas of the state about adult plant bugs at damaging levels in pin head square and older cotton.
• Plant bugs continue to increase on wild host plants on roadsides and field borders. Both dark (old) adults and immatures present in SE AL.
• Tobacco Budworms foliage feeding on peanuts near Enterprise, AL. Newer chemistry (Belt, Blackhawk, Steward) will be necessary for control.
• Fall armyworm (likely grass strain) feeding on peanuts in southwest AL. Pyrethroids will give excellent control.
• Snails in abundant numbers observed on cotton from Walnut Hill, FL to Columbus, MS. No controls suggested but net sampling for plant bugs difficult.

Early Armyworm and Thrip Control

Armyworms, either true or fall, in whorl of knee high corn in Mobile County. Pyrethroid is suggested for control.

Cotton planted April 10-12 at Prattville, Alabama is putting on first true leaf bud this week. Remember thrips control with seed treatments drop sharply at 21 days after planting (which with the cool nights in 2013) is about the time that thrips control is really needed.

The best timing for foliar thrips control is when plants are putting on the first true leaf bud. Acephate (Orthene or generic) is one of the most effective treatments.

Our objective should be to push the plant to about the 5^th true leaf stage as fast as possible. We want the largest and healthiest plant possible when we reach the 5^th true leaf. For that reason, the timing of a foliar spray is more effective at the 1^st true leaf than a spray at the 3^rd, 4^th or 5^th true leaf.

Just remember that what we see as far as thrips injury above ground is also happening below ground with the root system. We don’t want these plants, with 1000-1500 lb. yield potential, to start off with a stunted root system.

Update for Week of August 26

The cotton insect control season is basically over. I say that realizing that there are a few late maturing fields within the state that may still need a stink bug spray. There are even fewer fields that have high numbers of tarnished and clouded plant bugs present. Where growers are attempting to make a top crop, in fields that have exceptional yield potential, plant bug controls may still be applied. Our greatest concern now in cotton is boll rot and disease. The past few days of overcast skies and rain showers have increased boll rot. The next weeks forecast is much the same. Other than a few southwestern counties, the state was spared from the excessive rainfall from Isaac.

At present, the insect action is primarily happening in soybeans and to a limited degree in peanuts. The lep feeders are occurring on soybeans state wide. We have more soybean loopers on beans in the Tennessee Valley area of North Alabama than I can ever remember. This complex also includes the green cloverworm statewide and the velvetbean caterpillar as far north as Selma and Montgomery in central Alabama.

Loopers, (all are the soybean looper, more difficult to control) are occurring at 1 to 8 or more per sweep. Most of our beans are drill so we cannot use a drop cloth. Our threshold experience with loopers using drop cloths is well established at 5-8 per row foot. We are wrestling with a sweep net threshold. Two loopers per sweep are not causing more than 5% foliage loss while 8 per sweep is causing 30-35% foliage loss. Our threshold is 20% foliage loss with beans at the stage they are now. So somewhere between 2 and 8 loopers per sweep is a treatable level. Based on my field observations I would treat in the neighborhood of four loopers per sweep.

Stink bugs are increasing in beans and will likely continue to do so in the days ahead. Therefore, in many fields a stink bug material (pyrethroid) or acephate (Orthene) may need to be added as we treat for loopers with the recommended insecticides of Tracer (Blackhawk), Intrepid, Steward or Belt.

One or more soybean fields in Southwest Alabama are infested with the garden fleahopper at damaging levels. This is a first for this insect on soybeans. They occurred on peanuts in that area a couple of weeks ago.

Some peanut fields are also infested with this mix of caterpillar pests. In this mix we are also finding fall armyworms, southern armyworms, corn earworms, cutworms, yellow striped armyworms and immature burrowing bugs.

Both soybeans and peanuts need to be scouted weekly for the remainder of this season and future seasons. The old method of spraying an insecticide on soybeans or peanuts when fungicides are applied is really just a stab in the dark. The odds of this being good timing for insect control is somewhere between slim and none. With the price of beans we have to do a better job with insect control than automatic sprays based on the stage of the beans.

Most of our comments in the next week or so will be directed towards soybeans and peanuts.

Update for the Week of August 19

Our April-planted cotton is beginning to open, and has varying levels of boll rot due to the weather the past 7-14 days. This same weather pattern of frequent thunderstorms and overcast conditions has been ideal for the spread of leaf spot diseases in out late planted cotton.

Insects have been light-to-nonexistent in recent days. There are a few plant bugs present and stink bug numbers have increased in some fields. I am not sure if either are at damaging levels, especially the plant bugs.

I believe we could safely say that leaf spot diseases are potentially more important than insects for the remainder of the season.

Growers who have peanuts or soybeans should monitor these crops carefully for the remainder of the season. Peanuts are attractive to a number of foliage feeding insects – including loopers, fall armyworms, bollworms, budworms, green cloverworms, velvet bean caterpillars and cutworms. Two peanut fields in Monroe County were identified last week with a high infestation of the garden fleahopper. To my knowledge this is the first time for this insect on peanuts. I am not sure what kind of damage potential they present. However, in cotton this pest can cause extensive foliage damage by leaving all leaves with stippling type feeling.

This same type of damage in peanuts would seem to be just as economic as a foliar disease.

Soybeans would be susceptible to damage from all the leps mentioned under peanuts plus the pod feeders – podworms and stink bugs. Many of our beans are late, planted behind wheat, and were just in full bloom the past 10 days. These beans will be susceptible to insect injury for weeks ahead. Only by scouting will growers know when economic insect losses are occurring and when controls are needed. We already have some fields in Baldwin County with damaging levels of soybean loopers. Foliage loss was as high as 35% last week when I made surveys in that area. Soybeans will be the last crop that stink bugs are attracted to this season. Even though it has been a light stink bug season, if they all accumulate in soybeans late season, controls will likely be needed.

I have heard little from the Kudzu bug on soybeans after finding them in the northeast counties of Cherokee and Cleburne back in July. Follow up surveys are needed in that area whenever time permits.

As the season winds down we will get back with further updates as new information becomes available and the situation changes.

Soybean Insect Pest Update

Fall armyworms have been reported infesting pastures across Alabama and last week this pest was found feeding on soybeans in Lawrence County in the Town Creek area. These fall armyworms appeared to have moved from a bermudagrass pasture and crossed a wooded area to reach the soybeans. The caterpillars were feeding on the soybean foliage in the portion of the soybean field adjacent to the woods. Since this report from last week, fall armyworms and yellow striped armyworms have been found in many soybean fields in North Alabama at densities as high as 3 to 4 per 15 sweeps. Since theses armyworms have been found across the R2 to R6 soybeans, it is likely that these worms were derived from eggs deposited in the fields by moths. Only a very limited number of soybean fields have been treated strictly for foliage feeders in Alabama thus far---but numbers of green clover worms are increasing in north Alabama and velvetbean caterpillar numbers are increasing in south Alabama as far north as Monroe county. The economic threshold for foliage feeding caterpillars from pod set to maturity is as follows: Prevent greater than 20-percent leaf  loss. Treat prior to 20-percent leaf loss when five to eight foliage feeding caterpillars (soybean loopers, armyworms, green clover worms, velvetbean caterpillars)  0.25 inch long or longer, are present per foot of row.

Treat when you catch an average of 1.5 foliage feeding worms per sweep. Soybean loopers are harder to dislodge with a sweep net and each looper should be counted twice. Each larva eats a high percentage of the total amount of foliage it consumes during the last 4 to 5 days of the larval cycle. If disease is present in the population growers may wish to delay application  for 2 to 3 days, especially if larvae are less than a half inch long and populations are not much above the minimal threshold. Both fungal and viral disease can wipe out a caterpillar infestation within a week under the right conditions. Podworm and stink bug numbers have been below threshold levels thus far in the vast majority of soybean fields.  However soybeans planted behind wheat could see increasing populations of these two pests as we enter the pod-fill stage.  Three-cornered alfalfa hopper (3CAH) numbers are variable (usually less than 2 per sweep) but numbers in most untreated fields are increasing.  Some growers who applied a fungicide to their soybeans have also included an insecticide to reduce 3CAH numbers.  As soybeans mature we will see more fields with multiple insect pest species present.  At times there will be 2 or more species at densities which are just below treatment threshold levels. It can be difficult to make a treatment decision in this situation.  If you need assistance in making a soybean treatment decision you can call me at 256-627-3450.

Fine Tuning Cotton Insect Management for 2012

I. Thrips Control

1. Need for foliar overspray
• Influenced by planting date primarily but also to lesser degree by night temperature and overall growing conditions
• Seed treatments planted from early April to about May 10th would benefit from foliar overspray
• Seed treatments give 21 day thrips suppression as opposed to 28+ days with in-furrow granules
• What you see with thrips injury above ground is reflective also of underground root conditions and growth

2. Timing of overspray
• Most beneficial when most of plants have 1st true leaf about the size of a small finger nail
• Cotton with 4 or more true leaves usually does not benefit from overspray
3. Multi state research in 2011 indicated that acephate (Orthene or generics) was equal to or superior to all other choices
• Certain pyrethroids were a weak choice
• Bidrin is effective but I would suggest saving for stink bug control. New label limits total use of Bidrin in one season to 1.2 lbs active.
• New products tested: Benevia (Dupont) and Radiant ( Dow). Both looked very effective but not certain about registration date and cost.

II. Nematode Management

1. Rotation- peanuts, grain sorghum, corn
2. Variety selection- PHY367WRF has root knot tolerance
3. In-furrow granules
• Loss of Temik
• Meymik registered on December 22, 2011 (production and supply for 2012 uncertain)
4. Seed treatments
• Suggest to use on lower risk fields
• In high nematode risk fields would be like using a Band-Aid when a tourniquet is needed
5. Fumigate (Telone)
• Consider site specific nematicide placement (Precision Ag)
• Nematodes usually not evenly distributed across field
6. Deep tillage- grew cotton over 100 years without nematodes being a limiting factor- only since reduced tillage have they become a major problem

III. Plant Bugs

1. Movement from wild host into cotton influenced by climate
• Hot/dry results in high peak but short in time
• Wet/cool spring results in low movement over longer period
2. Most effective insecticides
• Acephate (Orthene, generics)- can flare spider mites
• Bidrin- good but only labeled for post bloom period
• Centric- effective but hard on beneficials and fire ants
• Pyrethroids- can flare spider mites
• Diamond- very effective on immature stage post bloom, especially when tank mixed with one of the above
• Intruder, Carbine, imidacloprid (Trimax), Belay, Vydate- less effective than others with one application

IV. Plant Bugs + Aphids (July)

1. Intruder, Carbine, imidacloprid (Trimax, etc.), Centric
2. Diamond may be combined with the above

V. Mid Season Worm Overspray

1. May be more important with Phytogen varieties
2. Timing could be mid July to early August depending on your north to south location
3. Pyrethroids are a good fit here
4. If brown stink bugs are also present, may want to select bifenthrin or Bidrin XPII (combination of Bidrin + Bifenthrin) or use highest labeled rate of other pyrethroids
5. Role of Fire Ants in Cotton
• Are the dominant beneficial in Alabama cotton today
• Not only important in conventional systems but also reduces escapes in Bollgard and WideStrike (Example: Mississippi consultants spray BGII on % egg lay)
• Some chemicals suppress fire ants more than others (Centric, Steward, pyrethroids, imidacloprid)
• Dr. Tim Reed and I conducted a project at Prattville last season (Poster Presentation)
• Results show less boll damage on both conventional and genetic cotton with fire ants in system as opposed to no fire ants
• Numbers on the side represent the number of worm damaged bolls per 45 feet.



Impact of Fire Ants On Bollworm
Damage in Alabama Cotton

VI. Fall Armyworms

1. 2010 and 2011 seasons have produced widespread outbreaks of the “grass” or “rice” strain of the FAW
2. This strain primarily attacks pastures, hay, grasses and peanuts and are easy to control with most insecticides, including pyrethroids
3. They do not prefer to feed on cotton or corn

VII. Stink Bugs

1. Some level of scouting needed for most economical control
• May need 0-4 sprays ($6-9 each considering application)
• Could pay for a field scout with savings or reduced damage from stink bugs alone
2. Most effective scouting is to examine 10-12 day old bolls for internal injury
3. Use “dynamic” or sliding threshold which considers the number of bolls at risk at a given week of bloom

4. Possible Reasons for Low Stink Bug Pressure in 2011
• Winter temperatures (colder than recent winters)
• Southern green stink bug is very sensitive to cold weather
• Impact of hot, dry spring on wild host/corn—may have reduced numbers of brown stink bug species
5.  New Stink Bugs
• Brown Marmorated Stink Bug
• Kudzu Bug (soybeans)
• Red-Banded Stink Bug (soybeans)  



Brown Marmorated Stink Bug



Red Banded Stink Bug

 

Kudzu Bug

 

VIII. New Products and Technology

1. Sulfoxaflor (Transform)- Dow
• Effective on plant bugs and aphids
2. Beseige (combination of Karate + Coragen)
• Effective on broad spectrum of caterpillars (loopers, fall armyworms), plus would have green stink bug activity
3. Endigo (combination of Karate + Centric)
• Effective on certain caterpillars, plant bugs, aphids and green stink bugs
4. Belay- in market place for past two seasons for plant bug/stink bug control
• Still need more University research to get a good handle on effectiveness
5. Prevathon (Dupont)
• One of most active caterpillar insecticides ever developed
• Excellent residual, depending on rate
• Very rainfast
• Should be targeted at egg stage or small larvae
6. Bayer Twin-Link
• Contains multiple Bt genes
• Performs somewhere between WideStrike and Bollgard II for caterpillar control
7. Bollgard III
• Under development
• Third gene is not a Bt so it has multiple modes of action for worms
• Reduces escapes over Bollgard II and will provide long term resistance management for the genetic technology
8. Poncho/Votivo Seed Treatment
• Insecticide + biological nematicide
• Looked at it in one trial on cotton and could see growth response and earliness, even under low nematode pressure



Overview of 2011 Cotton Insect Season

Early Season Pests
Thrips were extremely heavy from about April 15 to May 20. A major contributor to this heavy migration of thrips from wild hosts and wheat into cotton was the extreme drought conditions and absence of rainfall events during this period.

Plant Bugs
One peak movement of adult TPB into cotton occurred between June 20 and July 1. The majority of this infestation only happened in the earlier planted fields (most mature cotton). One insecticide application was targeted to these adult TPB’s when they were detected. Few immatures were detected in these fields in the coming weeks, so no in-field generation occurred. This may have been influenced by the extreme temperatures that occurred during this period (98-102⁰F).

Bollworm
Subeconomic numbers of bollworms occurred over an extended period from about July 15 to August 10. Few fields ever reached treatment threshold. 2011 was like the lowest bollworm pressure year on record. End-of-season damage boll counts on untreated genetic cotton were less than one boll per 10 feet.

Tobacco Budworm
Budworm numbers were non-detectable to extremely light all season long. Budworm larvae were too low to detect on conventional cotton and even on attractive crops such as tobacco when used as a sentinel crop.

Aphids
Aphid numbers were very slow to build in 2011 but also slow to crash due to naturally occurring diseases. The fungal disease was slow to develop which left aphids in the system much later than normal. Aphids normally peak and crash prior to, or at, the early boll set stage but this did not happen in 2011. Also, observations indicated a resurgence of aphids in the mid canopy area of the plants in late season as opposed to the terminal area.

Stink Bugs
Stink bugs in 2011 were fewest in number and damage of any year since the boll weevil was eradicated. This was likely due to the colder than normal winter temperature effect on the southern green species and the extreme spring heat and drought effect on the brown species. The majority of the few stink bugs observed in 2011 was the brown species.

Fall Armyworms
The “rice or grass” strain of the fall armyworm was abundant over much of the season in pastures, hay, and grasses. This strain will feed on peanuts but not on corn or cotton. They are easy to control on pastures with pyrethroids and numerous other labeled agricultural insecticides.

Weather and Insects Affect Late Season Cotton, Soybean and Peanuts

The greatest impact on cotton during the past two weeks has been the lack of rainfall. Drought and intense heat has resulted in the shed of all fruit less than 10 day old bolls from the terminals of plants. This will tend to shorten additional boll production by 2 to 3 weeks and will likely reduce the “top crop” by 200 or so pounds of lint in many fields. Rainfall in the next 7 days would still help fill top bolls that are not mature.

As the result of the above conditions, the insect control season, especially stink bugs, is about over. A few southern green stink bugs can be found in late maturing fields or “swag” areas that remain green in more mature cotton fields. Thresholds for these would be 30-50% internal boll damage on 10-12 day old bolls. A few fields would still profit from stink bug controls.

Tobacco budworms have been extremely low all season but field observations and pheromone traps indicate an increase in the past week or two. Also, bollworm moths are abundant this week in the southern counties of the state.

Soybean Insects- Soybean loopers are at economic levels of 5 or more per row foot in some Gulf Coast area soybeans. Chemical choices (in no particular order) are: Intrepid, Steward, Belt, Tracer and Besiege (Coragen and Karate). Dimilin will give good suppression and long residual. On cotton, the same can be said for Diamond.

Peanut Insects- Scouts reported a mixture of foliage feeding worms in peanuts in Monroe County (S.W. Alabama) about 10 days ago. Many of these were controlled or either they have cycled out by now. This mixture was dominated by bollworm and fall armyworm (grass strain) species. Also in the mix were a few green cloverworms, loopers, and granulate cutworms. Pyrethroids gave nice control of this mix.

Tarnished plant bug, aphid, tobacco budworm and fall armyworm numbers on the increase

Tarnished plant bug adults were found in numerous fields in western Alabama (Lamar County) on Friday (July 8). Pin head square loss was minimal (less than 5%) and very few immature plant bugs were found. This would indicate that adults had moved into cotton fairly recently. However, this is a situation where damage could increase rapidly if controls are not applied.

Several calls were received late last week about increasing aphid populations in some fields. Aphids are late developing this season, which means they also could be late crashing from the fungal disease. This being the case, the peak aphid stress will come during the early boll set window. Growers may find it best to apply aphid controls and prevent plant stress at this stage of maturity.

Heavy tobacco budworm damage has been occurring on sentinel plots of conventional cotton in SW Georgia for the past week. Growers with Bollgard II and Widestrike can sleep well at night knowing that their investment in technology is working to near perfection.

The “grass” strain of the fall armyworm is now damaging pastures and hay crops in several south Alabama counties. This strain will also feed on peanut foliage but will not feed on cotton.

Soybeans

Loopers are the dominant soybean insect, up to 30% defoliation and damaging levels in some fields. A few velvetbean caterpillar and green cloverworms are in the mix. The “grass” strain of the fall armyworm does not appear to feed to a significant degree on soybeans. And, stink bug populations are not as high as anticipated.

Red banded stink bugs were discovered on the Wiregrass Research Farm, Headland, AL (Henry Co.) this week. Since they were found about 180 miles west of Headland last month, they likely may be present in other locations across south Alabama.

Soybeans

Economic levels of soybean loopers, fall armyworms (FAW) and velvetbean caterpillars (VBC) are as far north as Marion Junction in Dallas county and FAWs are occurring near Prattville in Autauga county. Soybean loopers, usually a southern latitude insect are occurring at all points within the state. Both VBC and FAW can be controlled with less expensive chemistry than can the loopers.

Pasture/Hay

Fall armyworm populations are “hit and miss” at damaging numbers all over the state. Some fields have been hit twice within 2 weeks.

Soybeans

A sub-threshold level of several caterpillar species can be found in most fields statewide. These include green cloverworms, soybean loopers, podworms, fall armyworms, and in the southern areas of the state, velvetbean caterpillars.

If the fall armyworms should occur at treatable levels, growers need to know that they are likely the “grass” strain which can be controlled rather economically with pyrethroids, Intrepid or Dimilin.

Stink bugs, especially the brown species, are at treatable levels in some bean fields. Growers should remember that stink bugs affect the quality of beans more so than the yield. Where brown stink bugs are the primary target, I would suggest a high rate of one of the labeled pyrethroids. These include: Baythroid XL, Brigade (Discipline), Prolex, Karate Z, or Mustang Max. Several of these have multiple generic brand names.

Peanuts

Many of the same caterpillar species found in soybeans are also at sub-economic levels in peanuts. The one exception is fall armyworm. Another “flush”, about 20-30 small larvae per row foot, was found in peanuts near Shorter, AL (Macon county) yesterday (August 24). These armyworms do not always occur in all fields on a given farm. The same products – pyrethroids, Intrepid and Dimilin also provide good control of fall armyworms in peanuts. The quickest kill will come from pyrethroids while the longest residual will come from Intrepid and Dimilin.

Aphids and bug complex building, fall armyworms in second generation in pastures, fleahoppers appear

We’re getting more reports of aphids building in cotton. They’ve been slow to increase but still have reached treatable levels in some fields. While we were doing our beat sheets last week, I noticed in some of the older cotton that immature brown stink bugs were turning up where we had adult brown stink bugs earlier. So, they’ve been in there long enough now to turn over a generation. Most of the plant bug population right now are in immature forms coming off of the June adults. Fields that were sprayed for bugs appear to be pretty clean, but others have populations now that are at or will shortly be at damaging levels, so we’re really close to making applications to clean up the bug complex on everything.

We’re still not seeing signs of the huge tobacco budworm flight that was underway in southwest Georgia 2 weeks ago. It’s amazing how fast budworm activity drops off as you travel 2 counties west into Alabama. We have a long history of similar patterns – heavy pressure in south Georgia but hardly anything in southeast Alabama. We’re into the second generation of fall armyworms, the grass strain, in coastal Bermuda and other hay fields in southeast Alabama.

The garden fleahopper has been causing damage in a 25-acre cotton field in Mobile County. This is the first time I’ve seen the pest in cotton in the 39 years I’ve been working the crop and didn’t know for sure what the insect was when a consultant emailed me samples of the pest and damage. But Mississippi State University recently released an excellent color insect guide for cotton, and the garden fleahopper was included in it, which allowed me to ID the insect. Evidently, it’s been enough of a pest at some point in Mississippi cotton that it made the book.

I have a feeling we’ll see a lot of brown stink bugs in soybeans when they start setting pods. They’re certainly nearby, although probably not in soybeans to any degree yet. Stink bugs are smart enough that they won’t hang around too long in a crop that doesn’t provide a food source. Typically, they’ll leave corn within a week of when it starts drying down and, as if on cue, they’ll shift into soybeans when they start setting pods. We’re following a population of them right now at our Gulf Coast research station.

Tobacco Budworms on peanut foliage and Fall Armyworms in pastures

On 6/15/2010 tobacco budworms were reported to be feeding on foliage of peanuts in several locations across southern Alabama. A similar situation occurred in 2008 which required controls to prevent complete defoliation. Also on 6/15 Fall Armyworms (likely the grass strain) were reported in high numbers on hay fields in south Alabama. Controls were being applied.

High numbers of adult tarnished plant bugs continue to occur in many, but not all, cotton fields in central and southern Alabama. Controls may be warranted if pinhead square retention drops below 80% in Bollgard and WideStrike varieties. It would not be wise to treat conventional cotton for plant bugs during this tobacco budworm flight.
