Cotton Insect Management, 2011

  Points for Discussion in Coming Weeks:



1. Low Input System - Conventional vs. Technology


2. Evolution of Bt Cotton - Various Genes Involved. How do they compare and what is in the future?


3. Phase Out of Temik. What will be the greatest impact?


4. Stink Bug Research Towards a More Rapid Survey Technique. Factors that influence external vs. internal stink bug boll damage.


5. New Damaging Insects: Plataspid (Kudzu) Bug, Brown Marmorated Stink Bug, Red-Banded Stink Bug



Low Input System - Conventional vs. Technology

Based on the results of these trials, this investigator would conclude that conventional cotton can be grown in Alabama.


However, the economics would vary greatly depending on the weather, severity of the insect season and location.


Furthermore, it would require much expertise in monitoring insect populations and selection of the appropriate chemistry for the target insect species present.


Bottom Line: 2011 may not be the season to cut input costs -- but instead to focus on maximizing yield.
