Fifty Years Of Evolution In Cotton Insect Control — 1971-2021.

It has been quite a journey to have been a part of the most evolutionary period in cotton insects. I began my career as part of the new U.S. Department of Agriculture-Extension cotton IPM educational initiative in 1972 when boll weevils were the dominant cotton insect in Alabama.

The goal of the program was to increase awareness of a management approach to controlling cotton pests, a program which incorporated scouting and economic thresholds. It has become widely recognized as integrated pest management (IPM).

Representing about 250 years of cotton insect management experience are Ron Smith (center), and cotton consultants from left, Grady Coburn, Louisiana; Jack Royal, Georgia; Tucker Miller, Mississippi; and Ray Young, Louisiana.

Organophosphates

During the mid-1970s, our primary cotton insecticide was the organophosphate class of chemistry — products such as methyl parathion and Guthion, which were characterized by fast-acting activity but short residual. In addition, most chemicals in this class had acute human and mammalian toxicity.

The phosphate chemistry had excellent activity on the boll weevil but brought resistance in tobacco budworm and secondary pests, such as spider mites and whiteflies. Heavy use of phosphate insecticides also caused major problems with delayed maturity of the crop. This problem was so pronounced that a special session was added to the January 1976 Beltwide Cotton Research and Control Conference. 

Introduction Of Pyrethroids

In 1976, the pyrethroid class of chemistry became available, initially under an Environmental Protection Agency-issued emergency use permit (EUP). In 1978, pyrethroid insecticides (Ambush, Pounce and Pydrin) received full but conditional registration and became the major player in cotton insect control for the next decade.

For several years, pyrethroids were highly effective on most all cotton insects. Insect losses were very low, yields reached higher plateaus and maturity issues disappeared. Due to extended residual from pyrethroids, insecticide application intervals for boll weevils could be extended from five to seven days.

However, during the decade of the 1980s, tobacco budworms became resistant to the pyrethroid class of chemistry in some areas of the Cotton Belt. 

Boll Weevil Eradication

After more than a decade of development, comprehensive plans to eradicate the boll weevil were finalized in the early 1980s. One of the driving forces for eradication were concerns that boll weevils might develop resistance to the organophosphate chemistry, a possibility which would have wrecked the U.S. cotton industry.

Pyrethroids had activity on the weevil but were not as effective as the phosphates and were initially significantly more expensive. The boll weevil never developed resistance to the phosphates; in fact, the phosphate insecticide malathion was the primary insecticide used for eradication. 

The Boll Weevil Eradication Program began in northeastern North Carolina in the early 1980s. In the fall of 1986, the eradication effort reached Alabama, and by the summer of 1995, no economic losses to the boll weevil could be found anywhere in the state.

During the active eradication program period (1986-1995), insecticide-resistant tobacco budworms and impossible-to-control beet armyworms caused yield losses beyond anything ever observed or previously recorded. 

Bt Varieties Commercialized

At the end of the 1995 season — given resistance to tobacco budworms — the outlook for the future of cotton production in Alabama was bleak. Fortunately, genetically altered Bt (Bollgard) cotton varieties, which had been evaluated for the previous four seasons, were commercialized.

The new technology was readily adopted by Alabama growers, and 77% of the 1996 acreage was planted to Bollgard varieties. This rapid adoption was primarily in self-defense following the heavy losses to worms in previous years. However, planting this new technology brought with it rules and regulations never experienced before by growers.

Word was spoken that growers would never have to treat for worms again. This proved to be incorrect when in late July 1996, news of bollworm escapes in the Brazos River area of Central Texas spread across the Cotton Belt. 

Bug Complex Threatens

It was during this low-spray environment that the bug complex became more damaging. In north Alabama and the Mid-South states, the tarnished plant bug had to be monitored and managed more closely. In central and south Alabama, as well as the remainder of the Coastal Plains of the southeastern United States, stink bugs became the dominant economic insect. 

By the time better stink bug management was adopted, single Bt gene Bollgard technology began to lose its effectiveness and escape bollworms were more widespread. Experts had warned this would happen. The single Bt gene was nearly 100% effective on tobacco budworm but considerably less effective on the bollworm species. 

Anticipating this, Monsanto had begun work on stacking a second Bt gene, which was commercialized in 2009 and reduced the escape bollworm problems by about 90%. It was followed by Bollgard III in 2018. WideStrike from Dow AgroSciences with two Bt genes was introduced in PhytoGen varieties in 2005 and was followed by the third gene (WideStrike 3) in 2014.

The diamide chemistry developed by Dupont is now available and highly effective on most worm species when applied timely (small larvae) or in the egg stage. What would have been a significant development had it not been for the introduction of Bt technology back in 1996, was the introduction (1996-98) of spinosad (Tracer) chemistry by Dow AgroSciences. 

Sucking Pests, Bug Complex

More recent years of cotton insect control have been dominated by the emergence of sucking pests, such as aphids, spider mites, thrips and whiteflies (silverleaf), and the bug complex — plant bugs, stink bugs and leaf-footed bugs.

As we moved into this reduced foliar spray era following the elimination of the boll weevil and tobacco budworm, our chemical tools became more selective. The new caterpillar insecticides do not control sucking pests or the bug complex, and the sucking pest insecticides do not control the bug complex or escape bollworms.

Several insecticides targeted for the bug complex give limited control of sucking pests or escape caterpillars. Tankmixes of two or more insecticides are again often necessary. 

Staying Ahead Of Resistance

Our future may be described as a “stay ahead of resistance” in the decades ahead. Resistance issues are present today in the following species: thrips, plant bugs, bollworms, spider mites, aphids and possibly other species.

The greatest challenge in entomology is staying ahead of resistance and managing sporadic pests such as slugs, snails, cutworms, grasshoppers, three-cornered alfalfa hoppers, leaf-footed bugs and others. Reduced tillage has been a great advancement. However, this practice has created numerous cracks that are being filled by sporadic pests that require management inputs.

In summary, the past 50 years of cotton production and insect management have evolved in many, and in some instances, unexpected ways. What an evolution and what a ride for an Extension entomologist over the past five decades.

Peanut Insect Update

Oddly, spider mite calls have significantly picked up over the past week, tomorrow alone we received reports of mites in peanuts across south and central Alabama. We would typically expect the rains last week to knock mites out, but they seem to be doing just fine right now. With the storms coming, however, I would wait to treat in most situations. While the storms may not kill or eliminate the mites, it should greatly reduce their activity. This will buy us sometime until we can get back in the field. Keep in mind that Portal and Comite II are the only two labeled options we have in peanuts. When to terminate applications for mites can be a tricky call. Ultimately, when to stop treating mites will come down to a field-to-field decision. How far out until digging? How big is the population? What is the immediate weather?

Soybean Insect Update

Stink bugs have started showing up in many later planted fields across the state. In Prattville, redbanded stink bug has taken over our research plots. We have not had many complaints, so hopefully they are not widespread. This is one insect pest that can destroy the crop. The upcoming rains will complicate things as seed will not dry down as quickly as normal. If heavy RBSB populations are in fields, even at desiccation, consider an application of a pyrethroid to help knock them back, preserve quality and yield.

Our stink bug threshold is 6 stink bugs (green, southern green, brown marmorated or brown) per 25 sweeps. Applications can be terminated at R6.5 (R6 +7-10 days) For RBSB, threshold is 4 per 25 sweeps. 

A good thing is that overall, caterpillar pressure has been light this year. We have had reports of velvetbean caterpillars in south Alabama, but very few soybean loopers. VBC are easily managed with most labeled insecticides. For treatment decisions, our threshold is to prevent 30% defoliation  through R6.5 (R6 +7-10 days).

Tales of Cotton Insects: Friday August 9, 2024

The cotton situation is all over the board right now in Alabama. Plant bugs are building in some areas statewide and relatively quite in others. Overall, stink bugs have been low but are now beginning to build. Monitoring the situation and only treating fields with damaging levels will be the only way to maximize inputs from now on. With the current futures outlook on price, we need to ensure every dollar spent brings back more.

We have also received a few spider mite calls and questions have revolved around when to walk away. This can be a tricky call (as can be when to treat in general). A threshold for spider mites of 30-50% infested plants showing injury is the best we have. Some considerations for terminating treatments include age of the cotton and how bad the infestation is. Bolls that are expected to be harvested should be protected from mites until they are about 20 days old. How bad is too bad? This is hard to say, but you cannot walk away from a disaster. If mites are turning leaves red and defoliation can happen, action is needed.

Soybean Update (Scott Graham and Caitlyn Lawton)

Over the past week, we have received multiple reports of fall armyworm outbreaks in double cropped soybeans. In nearly every case, the armyworms started on volunteer wheat or on grass weeds and moved to beans after a herbicide application, or total consumption of the grass.

In 2021, we faced an epic fall armyworm outbreak, basically nationwide. We began hearing about pyrethroids missing worms in Texas as early as May that year. This year, while we have not hide widespread misses, we have received reports from north, south and central Alabama of control failures. So, what do we do in these situations?

Our general recommendation is still to use a pyrethroid, particularly if tank-mixed with a herbicide application targeted at killing grass weeds. Other options if pyrethroids fail or there is concern they won’t get the job done include:

acephate (0.75 lb)
Besiege (7 oz)
Diamond (6 oz) 
Elevest (5.6 oz)
Intrepid 2F (4 oz)
Intrepid Edge (4 oz)
Vantacor (1.2 oz)

Soybeans can withstand a fair amount of defoliation in the vegetative stage (30%) and the reproductive stage (20%). However, we do not want these late beans to be anymore delayed than necessary. Scout fields and be prepared to treat when needed. We do not have a threshold for sweep-nets or the number of FAW per foot, however some recommend action in double crop beans if 25% of plants are infested.

We have also begun receiving reports of stink bugs and soybean loopers infesting fields and requiring treatment. In addition to our traditional stink bugs species, we have also heard of some redbanded stink bugs in fields in central Alabama. In most cases, they are just part of the complex and not the dominate species. Threshold for stink bugs is 4 per 25 sweeps until R6. At R6 threshold is doubled to 8 per 25 sweeps for the next 7-10 days.

Our threshold for defoliating caterpillars (loopers, cloverworms, velvetbean caterpillars) is to avoid 20% defoliation during reproductive stages. For soybean loopers (SBL), treatment is recommended if 18 loopers (> 0.5 inch) is found per 25 sweeps. Velvetbean caterpillar (VBC) and green cloverworm (GCW)threshold is 36 per 25 sweeps. Most labeled insecticides do a good job controlling VBC and GCW, while newer materials (Vantacor, Besiege, Intrepid Edge, etc.) are needed to control SBL.

Pastures and Forages (Lawton)

Reports and infestations of fall armyworm are even higher in pastures and forages than soybeans. Our threshold in these situations is an average of 2-3 worms per square foot. As with soybeans, we have received sporadic reports of pyrethroids missing worms. In addition to pyrethroids, Intrepid 2F, Besiege, Vantacor and Dimilin are labeled for control. Keep in mind that Dimilin is a growth regulator and will be slow. Dimilin should be targeted at worms less than 0.5” long. Refer to the Pasture and Forage Crops IPM Guide (IPM-0028) for rates, other recommendations and preharvest/grazing intervals.

Regardless of the crop, we are likely to see at least one more generation of FAW this year, as their lifecycle is about 30 days long. Keep scouting and monitoring fields weekly to ensure you have not missed worms.

Tales of Cotton Insects: Thursday July 25, 2024

The cotton insect situation is as it has been all year, all over the board. Reports from South Alabama are that plant bugs are finally beginning to build in many fields but continue to be the heaviest near corn. Overall, bug pressure has been light in Central Alabama, but the bug complex (stink bugs and plant bugs) are beginning to be more common in some fields. Pressure is also picking up in some areas of North Alabama.

Bug Complex

 In some fields, plant bugs are easily found above threshold (3 per 5 row feet) and dirty blooms are apparent. This makes for an easy treatment decision. In other fields, numbers have been just below threshold for a couple weeks and the call is more difficult. In many cases, we have recommended “cleaning up” these fields. Conducting research on subthreshold populations is difficult, but I believe multiple weeks of numbers just under threshold will result in similar losses to one week of populations at threshold. Depending on planting date (or really age of cotton) insecticide options vary. In fields in early bloom, Transform is still a good option, however, fields at the 3^rd week of bloom or later need a material that also cleans up stink bugs. That means a pyrethroid or organophosphate. A few things to consider for decisions are rain patters, variety and efficacy. We observed ≈10% damage from bollworms in our Non-Bt cotton at the Prattville research station this week. While overall pressure was low in our Bollgard 2 (DP 1646) cotton, consider a pyrethroid for bug control to get the additional bump on bollworms.

Overall, stink bug damage has been light across the state, but our observations on research farms and in grower fields in central Alabama is that stink bugs are just now beginning to infest older fields. Threshold during peak bloom is 10% internal damage of 10-12 day old bolls (1 inch diameter, about the size of a quarter). Sample 20-25 bolls across a field and look for signs of feeding.

Aphids

The aphid fungus has caused populations to crash in many areas of the state. Before treating for aphids, look for the grey, fuzzy looking cadavers. The fungus is highly effective and will crash populations across a field in a matter of a few days.

Rainfastness Considerations

While some fields are still pretty dry, many are receiving rainfall pretty consistent. Rainfastness of insecticides has been a common question over the past couple days. Several factors impact the effectiveness of an insecticide application after a rain event.

In general, most insecticides are “safe” after about 6 hours. If a rain event happens 3-4 hours after an application, I would consider a reapplication. If rainfall happens 4-8 hours after, I would scout the field 3-4 days later to determine efficacy and treat accordingly. Two insecticides that are “exceptions” to the rules are Diamond and Acephate. Diamond has better rainfastness (≈2 hours) than most insecticides (Miss State Blog). Many of the insect growth regulators (like Diamond) have good rainfastness. On the other side, Acephate is among the least rainfast materials we have. At least 8 hours of no rain is needed, and up to 12 hours is better.

Amount and Intensity of Rainfall: More rain will intuitively have more impact than less rain. A hard, driving rain will probably be more detrimental than a slower, steady rain. In other words, a half inch in 30 minutes will probably be worse than a half inch in 3 hours.

Activity of Insecticide: Systemic insecticides (move inside the plant) are less likely to be severely impacted than contact insecticides. Most systemic insecticides require 2-4 hours to move into the plant. While some contact insecticides aren’t very rainfast, insects may come into contact quickly and have enough exposure immediately following the application to die.

The question remains, should you go ahead and “beat the rain” or hold off until it passes. That can be a difficult one to answer. Action will depend on how bad the infestation is, how likely the rain is, and how quickly you can get back into the field. If plant bug populations are well above threshold (3-4x threshold), I would consider taking the risk of wash-off and partial control vs allowing them another week to feed if I could not get into the field.

Soybeans

Things have been relatively quiet on the soybean front, outside of kudzu bug. This has been the worst year of my career with kudzu bugs. Many fields reached threshold for adults and needed treatment. In general, we do not recommend treating adult kudzu bugs, however populations were so high they could not be left unchecked. Kudzu bug feeding causes similar impacts as drought stress in soybeans. Many dryland fields across the state could not take the additional stress of kudzu bugs during a droughty period. We have observed reproduction in south and central Alabama and have even seen some naturally occurring fungus taking out kudzu bugs in central Alabama. We typically wait to trigger on nymphs and use a threshold of 1 nymph per sweep (=15 in 15 sweeps). Most pyrethroids provide good control of kudzu bug.

Defoliating caterpillar and stink bug populations have been low thus far in soybeans across the state. We will continue to monitor the situation and provide updates as pressure builds.

Tales of Cotton Insects: Monday July 8, 2024

Insect Pressure All Over the Board

Over the past week, we have received feedback from all cotton producing areas of Alabama. Adult plant bugs are still infesting some fields with nymphs showing up, while other fields do not have much, if any, plant bug pressure. Aphids are finally beginning to build, and spider mites are showing up in hot spots. Overall, insect management is a much of a field-to-field basis as I have seen in my career. Recommendations have been nuanced and rarely are the same from one call to the next.

Plant Bugs

North Alabama has experienced extreme plant bug pressure so far this year (both TN Valley and NE AL). Many fields received 2 adult plant bug sprays and some have received 3 applications. Overall, square retention remained above threshold (=80%) but continued infestations required multiple applications. Overall, the immature populations building in these fields has not materialized to heavy pressure yet. This is possibly due to a couple of reasons.

1.    Timely applications on migrating adults reduced egg lay. This is one reason why we recommend treatment if adult counts reach 8/100 sweeps, even if square retention is above 80%.

2.    I believe environmental conditions also play a role in the survival of plant bugs in the egg and early instar (hatchling) stages. The hot, dry weather we have faced over the past couple of weeks has likely killed many of the immature plant bugs that ordinarily would have hatched and developed over this time.

With all of this in mind, what does it mean for plant bug controls this week? For most of the older cotton, we are in the window where Transform (1.5 oz/A) has the best fit. Transform does a good job on adult and immature plant bugs, as well as aphids, without flaring spider mites. Traditionally, this is the window where we also recommend Diamond (6 oz/A) as a tank-mix partner to give residual suppression of immature plant bugs. However, this year, based on reports we are receiving, some fields may not need Diamond right now. Fields that received an initial adult plant bug spray in the first week or 2 of June still do not have either high numbers of immatures or many dirty blooms (a common symptom of immature plant bug damage). In these cases, we are recommending to “treat what’s in the field” and not make an automatic Diamond spray right now. Immature plant bug populations are too sporadic to make blanket sprays. That is not to say that Diamond is not or should not be going out in many fields, but our recommendations are on a case-by-case basis.

Aphids

As mentioned above, aphids are beginning to build across the state, and we have not received any reports of the fungus showing up. Aphids feed on plant juices and secrete a sugary substance called honeydew. This feeding slows down plant growth and development. This is exacerbated in situations where cotton is already not growing well, such as the hot, dry weather we have been experiencing. We do not consistently get yield responses when conducting efficacy trails for aphids, but we can see increased yields when cotton is drought stressed. In trials done across the southeast in 2019-20, Transform and Assail provided the most consistent control, while imidacloprid, Centric and Bidrin provided less consistent control, but enough to alleviate plant stress from heavy plant bug pressure.

In most cases, we do not recommend aphid treatments, and typically plant bug sprays “clean-up” any aphid populations. Populations will continue to increase until the naturally occurring fungus, Neozygites fresenii, takes over. Generally, populations crash about a week after these grey, fuzzy aphids appear.

Soybeans

A quick note on soybeans. Kudzu bugs have begun infesting fields in big numbers over the past 10 days or so. In central and south Alabama, reproduction is beginning to occur. In north Alabama, egg lay has not been observed. The presences of immatures is important, because this generally signals the end of adult movement into fields. Our threshold from R1 through R6 is 10 adults per sweep (250/25 sweeps) or 1 nymph per sweep (25/25 sweeps). If immature kudzu bugs are easily and repeatedly found on petioles and main stems during visual inspection of the canopy, treatment is likely warranted.

Tales of Cotton Insects: Thursday June 13, 2024

Critical Window for Early Planted Cotton in Central and North Alabama

The plant bug situation has exploded over the week in Central and North Alabama. Based on reports and observations from about Montgomery north through the TN Valley and NE Alabama, all cotton planted on or before ≈May 10^th likely needs a plant bug spray. Overall, square retention is still high, but with some of the numbers reported, it will start dropping quickly if action is not taken (goal is to maintain 80%). Overall, pressure appears to be lighter in cotton planted on or after ≈May 15^th (much of that is just starting or not squaring yet). Note: Reports are that adult plant bug numbers are similar in ThryvOn and Non-ThryvOn cotton in most areas. This is not unexpected as most of ThryvOn’s  impact is against immature plant bugs.

Multiple reports from Cherokee county are that the earliest planted fields are running anywhere from 20-35 adult plant bugs per 100 sweeps (threshold = 8). In these situations, imidacloprid alone may not be enough to preserve square retention. Adding mid-rates of acephate or a pyrethroid (depending on location) may improve control. Centric is another option for control.

In most situations populations are above threshold but in more manageable numbers. Our May 1^st planted cotton at Prattville averaged ≈12 adults per 100 sweeps this week and ≈9 per 100 sweeps at TN Valley. We have received some reports from the field of similar populations and that some fields are receiving a 2^nd adult application this week (following applications last week). High rates of imidacloprid alone, Centric (2 oz), acephate (0.5-0.67 oz) or pyrethroids (highest labeled rate, dependent on location) should suppress populations and preserve square retention. Keep in mind that no insecticide will provide more than 2-3 days of residual control for adults and square retention is the best way to determine efficacy, adult numbers can rebound from week to week as more move into fields.

Thus far, reports from south Alabama are that plant bugs are scattered here and there, but few fields are above threshold. These fields should be closely monitored as the migration will likely begin soon.

The next 10-14 days will be critical for plant bug management in central and north Alabama cotton. Timely applications of recommended insecticides will preserve square retention and reduce egg lay and nymphs hatching out in the coming weeks. Consider being prepared to make an application of Diamond with a knockdown insecticide ≈10-12 days following the adulticide applications going out now. One consideration for the “automatic” follow up may be weather. If fields do not receive rain in the next couple weeks, that may impact immature plant bug populations in our favor. Plant bug nymphs do not seem to handle hot, dry conditions very well. Particularly in the hatchling stage.

Plant Bugs Invading Alabama Cotton

Over the couple days, we have received multiple reports or observed adult tarnished plant bugs in April or early May planted cotton across central and north Alabama. In most cases, populations were below threshold, and a few squares were missing. However, some fields are at threshold and treatments are going out. Thus far, reports from southwest and southeast Alabama are that few or no plant bugs are being observed.

As our earliest fields begin to square, monitor pinhead square retention on the upper 2 or 3 nodes of plants. Our goal is to maintain 80% of these first position squares (closest to the mainstem). The reason to monitor the upper 2 or 3 nodes each week is that these are the “new squares” that were put on in the current week (added since last week’s scouting trip). In addition to monitoring square retention, a sweep-net is a good monitoring tool to determine the level of adult plant bugs in the field (threshold is 2 adults per 25 sweeps). Even if square retention is above 80%, we recommend treating adults because they will start feeding on pinhead squares and depositing eggs that will hatch in the following 7 to 10 days.

Our general recommendation for adult plant bug control is the high rate of imidacloprid or 1.75-2oz of Centric. In some areas, bifenthrin is also an option. In cases of high pressure, acephate may also be considered or tank-mixed with imidacloprid. We generally try to stay away from acephate and bifenthrin to preserve better beneficial insects and for resistance management, however under heavy pressure we need to worry about plant bugs and deal with other issues if/when they arrive.

Based on our observations in daisy fleabane this spring, we suscept this could be a multiple spray year for adults in June, particularly for early planted cotton. Remember that as long as square retention is at or above 80% a previous application “did its job” and more adults have moved into the field. Also keep in mind that June applications for adult plant bugs can set the tone for the rest of the season. By knocking back adults, we are reducing egg lay and nymphs that hatch out later as blooms begin to appear.
