Those varieties will generate economic benefits for producers while helping safeguard the environment. An additional goal of the breeding program is to develop information on genetics and breeding methodology that will improve the productivity of all breeding programs in the Delta. Entomologist Aubrey Harris is conducting research aimed at producing effective insect management systems for cotton, as well as soybeans and rice. In recent years, Harris has conducted small-plot field experiments that have shown transgenic Bt cotton lines provide excellent bollworm and tobacco budworm control. His research has shown that close monitoring of crop development can result in 2 to 3 fewer insecticide applications each season with no reduced profits for producers.
Weed control is another management practice that can determine whether a crop is profitable.
Weeds are estimated to reduce rice yields by an average of 10 percent in the Delta. Plant Physiologist Joe Street is evaluating chemical, biological, and cultural means of rice weed control to determine the best management practices with minimum input. Weed Scientist Gene Wills is researching new methods of weed control in cotton and soybeans. Part of his work involves the addition of surfactants to herbicides for improved control, reduced cost, and environmental benefits. He also is seeking new methods to control MSMA herbicide-resistant cocklebur in cotton.
