Chemical control of sorghum shootfly, Atherigona varia soccata Rond and sorghum stem borer Chilo partellus (= zonellus) Swinhoe on hybrid sorghum CSH-1

Nine insecticides were tested in the field in Maharashtra, India, in 1969-70 for the control of Atherigona soccata Rond. (varia soccata) and Chilo partellus (Swinh.) on sorghum. Against A. soccata, soil application of 10% phorate granules at a rate to give 1.5 kg active ingredients/ha proved the most effective, with whorl applications of 2% endrin granules and 5% monocrotophos granules, affording good control. Monocrotophos had some phytotoxic effects. All the foliar spray applications tested were ineffective. In tests on the control of C. partellus, the granular formulation of endrin and sprays of 0.2% carbaryl, 0.03% endrin and 0.05% endosulfan afforded good control and led to increased yields
