Production practices and new technologies that reduce costs and optimize production continue to be critical issues that producers ask Extension/Research personnel to address. This project was implemented to evaluate and identify new technologies and production practices that are most profitable in the Texas Gulf Coast. This project was implemented in two distinct growing areas of the Texas Gulf Coast - the Upper Gulf Coast and the Coastal Bend.

Fourteen cotton variety trials were planted throughout the Gulf Coast region in 2012. These variety trials were conducted to assist producers in making sound variety selection decisions.

In past years, 2,4-D amine has been the chemical of choice and has provided excellent control of cotton stalks. However, the Enlist™ Weed Control System, which will include cotton tolerant to a new form of 2,4-D is currently under development by Dow AgroSciences. Therefore, alternatives to 2,4-D amine for post-harvest cotton stalk destruction were evaluated. 2012 results show that effective herbicides will be available to control 2,4-D tolerant cotton stalks when it becomes commercially available in 2016.

Two cotton defoliation trials were conducted in Nueces and Wharton Counties to evaluate which products were performing the best under this year's environmental conditions.

A preplant herbicide trial was conducted in Fort Bend County to evaluate seven different herbicide treatments and their effect in controlling emerged henbit and their ability to reduce early season emergence of glyphosate resistant waterhemp. Preplant applications of Goal herbicide provided excellent preemergence control of glyphosate resistant waterhemp.

Insecticide applications were made at different weeks during the squaring period of cotton and their subsequent impact on lint yield and fleahopper numbers. No yield differences in lint yield were observed among the different timings and the untreated check. Due to the limited soil moisture conditions in 2012, plants were simply not able to hold the fruit that had been protected from the fleahopper. However, when number of adult and nymph fleahoppers was combined, significantly more were observed in the untreated cotton.

Education programming efforts pertaining to cotton production issues were disseminated at 20 meetings reaching over 1,358 people involved in the cotton industry.
