Foliar applications of ethyl parathion, carbaryl, carbofuran, and Penncap M® (0-0-Dimethyl O-P-nitrophenylphosphorothioate) significantly reduced numbers of Blissus leucopterus leucopterus (Say) on sorghum. Granular phorate and carbofuran applied in the soil successfully controlled chinch bugs in laboratory tests but were not to effective in one field test. Thirty adult chinch bugs/plant killed 75–125 mm sorghum plants in 6–7 days and fewer caused death or severe stunting, depending on plant size. More than 1700 chinch bugs/plant at bloom stage significantly reduced sorghum yields. 'Early Sumac' was significantly more resistant to chinch bugs than 'Honey', 'Redlan', or 'Spanish Broomcorn', which were almost equally susceptible.
