Botryodiplodia Stem End Rot of Mango and Its Control

Abstract

Botrydiplodia theobromae, the causal organism of stem end rot disease of mango was studied. Isolates of B. theobromae obtained from different sources had different degree of disease severity. Isolate from diseased mango fruit was whe most virulent isolate. Six cultivars of mango were tested on their susceptibility. Okrong was the most susceptible cultivar. Length of pedicel also had an effect on disease development. Disease developed slower on the fruit with longer pedicel than on the shorter one. Control measure of the disease with different means indicated that dipping the fruits in benomyl at concentration of 500 ppm at 52 ^oC for 5 minutes was the most effective mean.
