Abstract:

| Cotton is the major cash crop and is known as white gold. The present study was conducted to evaluate and compare the commercially available pesticides and indigenously available plant extracts. The efficacy of following insecticides and plant extracts viz. Cascabela thevetia leaf extract @ 300ml/acre, Azadirachta indica @ 300ml/acre, Profenofos @600ml/acre., Crown 70WS @125gm/acre, Match 50EC@250ml/acre, Helmat 40EC@600ml/acre and Confidor 20SL@ 250ml/ acre were evaluated on cotton against 3rd instar cotton mealy bug. Data was collected after 3,6,12,24 and 48 hours. Maximum mortality of cotton mealy bug was recorded in Syngenta 50EC (profenofos) are 42%, 62%, 80%, 88%, 94 % while Match 50EC exhibit minimum percentage of mortality is 22%,34%,48%, 72% and 76% after 3, 6, 12, 24 and 48 hours respectively.
