New cotton trait varieties tackle insects, fight weeds and improve livestock feed.

Staff “We need to minimize selection of bollworms on Vip proteins as much as possible,” Sebe Brown said. Entomologists encourage producers to be aware of older Bt traits as insect resistance begins to wane. The No.1 variety consideration for cotton growers is to choose one that performs well under specific locations and field conditions. Yield and quality pay the bills. Entomologists encourage producers to also be aware of some of the older traits (Cry1 and Cry2) as insect resistance begins to wane. “Things have not gotten worse,” said Scott Stewart, Universi...

Scott Stewart Getting control of bollworms is important. If you must make two applications of a foliar insecticide for controlling worms, the expense can add up quickly. Research on cotton bollworm shows what genes and insecticides are providing better control for this prominent pest. Since bollworm is a major pest in cotton for the Midsouth, adequate control of this pest is important to overall yields and profit. Research shows that it may be time to make the switch to three gene cotton to help control bollworms. Gus Lorenz, Distinguished Professor and Extension Ent...
