Evaluation of insecticides as sprays and dusts for the control of sorghum earhead bug (Calocoris angustatus L.)



Evaluation of insecticides as sprays and dusts for the control of sorghum earhead bug (Calocoris angustatus L.)



Indian Journal of Plant Protectionrecd 11(1/2): 13-16



Field trials were carried out in Andhra Pradesh, India, in 1975-78 to determine the relative effectiveness of various insecticides as sprays or dusts against Calocoris angustatus on sorghum. Phenthoate, carbaryl and malathion as dusts at 1.5 kg a.i./ha, quinalphos as a dust at 0.375 kg a.i./ha and chlorpyrifos as a spray at 0.3 kg a.i./ha were highly effective against the pest, while leptophos and carbaryl as sprays at 0.5 and 1.5 kg a.i./ha, respectively, were fairly effective.
