SENSITIVITY OF ALTERNARIA ALTERNATA AGAINST CARBENDAZIM CAUSING FRUIT ROT OF POMEGRANATE

It was found that there was variation in the MIC of carbendazim among 21 isolates of Alternaria alternata (Fr.) Keissler on agar plates and on pomegranate fruits. MIC on agar plates ranged from 500 to 1000 g/ml and Ed50 from 325.33 to 693.75 g/ml, while it was 100 to 350 g/ml and Ed50 33.76 to 136.48 g/ml, on fruits Collected from Kolar (Dist. Ahmednagar), Parali (Dist. Beed), Mahabaleshwar (Dist. Satara), Rahuri (Dist. Ahmednagar) and Sangli. It appears that with the increase of the concentration of fungicide in the medium and on the pomegranate fruits there was decrease in the radial growth of the pathogen.
