Abstract

                                A field experiment was conducted in Rameswaram island to study the effectiveness of certain Insecticides and neem oil against blossom midge, Contarinia sp. which caused purple discolouration and drying of flower buds in Jasminum sambac. The results indicated that monocrotophos 0.1% was superior to other insecticides and neem oil in reducing the discolouration. Cypermethrin 0.012%, fenpropathrin 0.05%, fenvalerate 0.02%, chlorpyriphos, 0.05%, dimethoate 0.06% and neem oil 2% were moderately effective.
