THE EFFECT OF THREE PESTICIDES AND PESTICIDE INTERVAL ON Cinnamomum verum galls in Southern Sri Lanka.

Abstract

Experiments performed to find a suitable pesticide and a pesticide interval to control a gall causing insect Triozu cinnamomi indicated that there was significant effect of all three insecticides monocrotophos, lannate and methamidophos on tested distribution of galls at 3 crown levels tested. There were no significant differences between the crown levels in respect of gall distribution. Monocrotophos (30ml/25L) was found to be the most effective pesticide and 4 days interval was found to be the best spraying interval to control gall causing insect T. cinnamomi
