We had a few calls over the last week about poor control of cotton aphid with Transform. In all of those cases, the field was actually sprayed for plant bugs with a 1.5 oz rate of Transform. That rate should be very effective on cotton aphid based on previous experience. As a result, we collected aphids from three different fields this week to test their susceptibility to Transform. . . . → Read More: Managing Cotton Aphids in 2014

Tarnished plant bug numbers have actually started off at low to moderate levels this year in the Delta region but just in the last few days numbers seem to be picking up pretty good in a few locations and square retention is not optimal. I have mentioned on numerous occasions the inability to adequately access product . . . → Read More: Assessing Control of Tarnished Plant Bug in Prebloom Cotton
Several folks throughout the state have began applying plant growth regulators to their cotton crop and many more will likely start over the next couple of weeks. Although plant growth regulators have gotten exponentially cheaper over the past 25 years, the basic chemistry of these products has remained unchanged. First and foremost, do not use plant . . . → Read More: Plant Growth Regulator Use in Cotton Production
Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working. Numbers alone can be deceiving when adults are steady moving into the field. When large numbers of adults are migrating into a field it is not uncommon to have as many or more plant bugs 4-5 days after a spray than you did before you sprayed and it still would not equate to a control failure. . . . → Read More: Importance of Monitoring Square Retention in Young Cotton

However, several things should be considered when assessing a potential re-plant situation. The number of healthy plants in the field should be considered first and foremost. Based on research conducted by . . . → Read More: Cotton Re-Plant Decisions – Plant Populations
