“…Chandi et al (2016) also reported that the percent reduction in leafhopper population was the highest with flonicamid 50 WG which is in concurrence with present findings. The efficacy of diafenthiuron and buprofezin against the sucking pests in cotton and other crops was reported earlier (Sreekanth and Reddy, 2011;Zala et al, 2014;Bajya et al, 2016;Kumar et al, 2015;Nemade et al, 2015;Jadhav et al, 2017) in cotton. The better efficacy of insecticide molecules with new chemistries over entomopathogenic fungi and other biopesticides was reported earlier (Kalyan et al, 2012;Saner et al, 2013), thus confirming the present findings.…”

A field experiment was conducted to evaluate the efficacy of certain new molecules as well as entomopathogens as foliar sprays against leafhoppers in Bt cotton at Regional Agricultural Research Station, Lam, Guntur, Andhra Pradesh for two consecutive years. The new molecule, flonicamid 50% WG at two doses i.e. at 75 g a.i./ha and 100g a.i./ha followed by diafenthiuron 50% WP 300 g a.i./ha and buprofezin 25% SC @ 250 g a.i./ha were found promising against leaf hoppers together with high seed cotton yield. New molecules were found significantly superior over to NSKE 5 % and entomopathogens in suppressing the leafhoppers.
