THE NEW TRANSGENICS: WILL THEY BE COST EFFECTIVE FOR ARKANSAS COTTON GROWERS?

Gus M. Lorenz, University of Arkansas-Coop Extension

Large block trials were conducted to compare conventional, WideStrike and Bollgard varieties and evaluate profitability of each system in North, Central and South Arkansas locations. Conventional cotton was treated for heliothines twice at each location while only the Central location treated once for heliothines in the WideStrike and Bollgard II treatments. Bollgard II had the highest yield at all three locations followed by WideStrike and conventional cotton. In small block trials, new insecticides Prevathon, Besiege and Belt increased yields above standard insecticides and when conventional cotton treated with Prevathon was compared to Bollgard II and WideStrike it had comparable yields to the dual gene cotton. In small plot trials, we observed  a higher level of control with the new foliar insecticides compared to existing standards and that these products even on dual gene cotton can significantly increase yields. Also, conventional cotton treated with the new insecticides rivals control of dual gene cottons.
