Abstract:Three insecticides at 2 rates were evaluated for control of Contarinia sorghicola (Coquillett) on grain sorghum near College Station, Texas. Infestations of midge were based upon the numbers of damaged seeds of grain sorghum heads harvested at maturity.
Based on this technique all insecticides tested reduced the midge infestation. Yields were increased by application of diazinon (0.25 and 0.50 lb AI/acre) and disulfoton (0.25 lb AI/acre). Applications of azinphosmethyl (0.25 lb) and disulfoton (0.50 lb AI/acre) did not increase yields.
