Effect of Insecticides, Fungicides and Flower Hormones on Mango Yield*

Studies were conducted on mango cv. Langra to find out the individual as well as combined effect of insecticide, fungicide and flower hormone on hoppers, other insect pests, diseases, fruit set and finally fruit yield. The treatment of insecticides + fungicide + hormone showed best results in hopper con rol, fruit set, number of fruits harvested and fruit weight followed by insecticide + fungicide whereas the treatments of insecticide only and insecticide + hormone were at par. Hopper population was higher but, significantly less than control in fungicide, hormone and fungicide + hormone. However, fruit set and fruit yield were recorded zero in all these treatments.
