Abstract :
The present studies were conducted to evaluate efficacy of three IGRs, Viper® (Buprofezin), Match® (Lufenuron) and Priority® (Pyriproxyfen) alone and in combination with two insecticides used for seed treatment [Confidor® (Imidacloprid) and Contest® (Thiamethoxam)] at their field recommended dose rate against Chilo partellus Swinhoe (Pyralidae: Lepidoptera) and Atherigona soccata Rodani (Muscidae: Diptera). Confidor® as seed treatment alone kept the C. partellus and A. soccata infestation below their ETL (10%) for 30 days; whereas, Contest® for 15 days only. Mortality of C. partellus larvae and A. soccata maggots increased upto 21 DAT and 14 DAT in Confidor® and Contest® treated plants, respectively. Match® a nd Priority® alone or in combination with seed treatments exhibited 80-100% reduction in C. partellus infestation and 65.3-100% larval mortality upto 15 DAT. Viper® alone did not performed, however, its performance in combination with Confidor® increased for C. partellus. Against A. soccata, all evaluated IGRs, alone or in combination with seed treatment, exhibited 80-100% reduction in infestation and 75-100% maggots mortality upto 15DAT. The results reveal that Match® and Priority® in combination with Confidor® seed treatment can be better alternate to granular insecticide application for the biorational management of C. partellus and A. soccata on maize.
