abstract
Management of mango hopper with newer chemical pesticides, entomopathogens and botanicals was carried out both under pot culture and field conditions during 2014-15 in UHDP mango orchard at R & D farm, JISL, Udumalpet, Tamil Nadu. Results of the experiment indicated that imidacloprid 17.8 SL @ 0.007% was superior to all the pesticide treatments with maximum mortality of the hopper observed on 1, 3, 7, and 14 day after spraying both in I and II sprays with mean mortality of 95.35 and 94.06 percent respectively and on par with thiomethoxam 25 WG @ 0.0025% expressing next best efficacy with mean mortality of 93.99 and 88.56 percent respectively. Malathion 0.075% though found effective was least effective among chemicals pesticides tested. Among botanicals neem oil and pungam oil at 1% were found on par with each other in their efficacy and found superior to NSE 5% with a mean mortality ranging from 79.71 – 66.40 percent in both I & II rounds of spray. The entomopathogens Lecanicillium lecanii 1.15%WP was found superior in controlling the mango hopper with a mean mortality of 86.04 and 71.99 percent recorded both in I and II round of spray treatment respectively under field conditions.
