Abstract:
Experiment conducted to study the efficacy of newer molecules against leafhopper during Kharif, 2004. The results revealed that, the lowest number of leafhopper noticed in imidacloprid 17.8 SL @ 36.5 g a.i./ha (6.13 leafhopper/ 6 leaves/plant) followed by oxydemeton methyl 25 EC @ 175 g a.i. /ha (8.26 leafhopper/ 6 leaves/plant), thiamethoxam 25 WG @ 25 g a.i./ha (9.66 leafhopper/ 6 leaves/plant) and Acetamiprid 20 SP @ 20 g a.i./ha (11.53 leafhopper/ 6 leaves/plant) compared to rest of the treatments. Similarly the maximum yield of 1100.33 kg/ ha was obtained in imidacloprid 17.8 SL @ 36.5 g a.i./ha followed by oxydemeton methyl 25 EC @ 175 g a.i. /ha (1020.00 kg/ha), thiamethoxam 25 WG @ 25 g a.i./ha (1037.66 kg/ha). Whereas, the lowest seed yield was recorded in untreated control (755.33 kg/ha).
