Abstract

Sorghum earhead bug (Calocoris angustatus L.) is considered to be a potential insect pest of sorghum next to shoot fly in Andhra Pradesh. Trials were conducted during 1975 to 19.78 at Agricultural Research Institute, Rajendranagar, to determine the relative efficacy of different inse.cticides as sprays and dusts. The results indicated that the insecticides viz., phenthoate dust @ 1.5 kg a.i/ha, chlorpyriphos spray @ 0.3 kg a.i/ha, carbaryl dust @ 1.5 kg a.i/ha, malathion dust @ 1.5 kg a.i/ha and quinalphos dust @ 0.375 kg a.i/ha were found highly effective against the earhead bug. Other effective insecticides were1eptophos spray @ O.5 a.i/ha and carbaryl spray @ 1.5 kg a.i/ha. The efficacy of the insecticides viz; quinalphos spray, endosulfan spray, diazinon spray, endosulfan dust and BHC dust was found to be intermediary. The insecticides found less effective were pyro-colloid, phosalone and DDVP sprays. Dust formulation was found superior to spray formulation of the same insecticide
