Farmers should take advice from the experts for use of insecticides and other information regarding the crops. Fruit flies infected fruits should be picked and buried in the soil. Protection of cucurbitaceous crops against fruit fly by use of bait trap (mixing juggary 10 % with Malathion 0.1 % and putting at different corners of the field) is advised. If the symptom is more, spraying of Imidacloprid 30.5 @ 0.25 ml /litre water is advised, when sky remains clear.

13.  Farmers are advised for constant monitoring of cotton crops against sucking pests and Mealy bug, if the insect population is above ETL then spray of Imidacloprid 0.5 ml./litre of water is recommended when sky is clear. Installation of pheromone trap @ 2-3 traps per acre of crop field is advised for monitoring and control of insect of cotton crop.

14.  Constant monitoring of lady finger, chilli and cucurbitaceous crop against attack of mite and jassid is advised. If insect population is above ETL than, spraying of Imidacloprid 17.5 SL @ 0.5 ml /litre water is advised, when sky remains clear.
