Abstract
In tests in South Dakota, sorghum was treated at sowing with granules of the systemic insecticides acephate [O.S.dimethyl acetylphosphoroamidothioate], disulfoton, CGA 12658 [O,O-diethyl O-(1-(1-methylethyl)-1H-1,2,4-triazol-3-yl) phosphorothioate], carbofuran, Counter [S-(t-butylthio)methyl O,O-diethyl phosphorodithioate] and aldicarb at various rates. It was found that sorghum treated with the last three products had the lowest populations of Schizaphis graminum (Rond.) 37 days after sowing and the lowest populations of parasitised aphids 58 days after sowing. These populations were not significantly different from populations in the untreated check. At 37 days after sowing, sorghum treated with certain rates of carbofuran, CGA 12658 and aldicarb had parasitised populations that were significantly lower in their numerical differences from the untreated check populations. The parasites were tentatively identified as Lysiphlebus testaceipes (Cress.) and Pachyneuron siphonophorae (Ashm.)
