Abstract: The studies indicated that maximum spore counts of Colletotrichum truncatum were observed during last week of July and first week of August which coincided with the critical stages of infection to the pathologen. Further, 25 standard week was highly favorable for appearance and development of Anthracnose of greengram (Vigna radiate L.) spore load and per cent disease index of anthracnose indicated a negative correlation with temperature and positive correlation with relative humidity and rainfall. The multiple linear regression equations arrived for spore load and disease incidence were Y= 344.10-2.42 X₁ -8.32 X₂-.83 X₃ 0.07 X₄ -0.07 X₅ and Y= 1349.88+16.37 X₁-75.27X₂ -2.72 X₃ +0.92 X₄ + 0.09 X₅.
