Abstract
Okra (Abelmoschus esculentus L.) is one of the most popular
vegetable grown in tropical and sub-tropical regions. It is widely grown for its
tender fruits, which are good source of minerals, fibers and vitamins. Okra crop
suffers heavy yield losses during cultivation in both summer and rainy seasons due
to pests and diseases infestation owing to congenial environmental conditions.
Jassid, aphid, whitefly, mite, fruit borer and yellow vein mosaic are the major
pests and diseases of okra. Weather plays an important role for initiation and
development of pests and diseases in summer okra as well as determined the yield
of okra in terms of quality and quantity. Keeping above in view, the field
experiment was conducted in summer season 2009 at Agronomy Farm of B.A.
