ABSTRACT
Okra, Abelmoschus esculentus (L.) Moench is one of the most important vegetable crops cultivated in India and because of its high nutritional values and human disease curing ability it is largely consumed all over the world. It is attacked by about twenty insect pests during different growth stages of which, jassids or leaf hoppers attacks the crop at any stage of its growth. The study of the seasonal incidence of jassids in relation to weather parameters gives idea for application of different insecticidal sprays for their effective control. Evening relative humidity had significant positive correlation with leaf hopper (r=+0.4525), whereas rainfall showed negative correlation with leaf hopper population on okra (r=-0.4203). In present investigation, insecticidal treatment with acetamiprid 20 SP @ 15 g a.i./ha was found most effective against leaf hoppers and it was at par with the treatment acetamiprid 20 SP @ 15 g a.i./ha followed by V. lecanii @ 2.5 kg/ha, thiamethoxam 25 WG @ 25 g a.i./ha, thiacloroprid 21.7 SC @ 54 g a.i./ha and acephate 75 SP @ 500 g a.i./ha respectively.
Key words: Okra, Leaf hoppers, Seasonal incidence, Newer insecticides, Biopesticides.
