Abstract

Incidences of vascular wilt disease caused by Fusarium solani in ten provenances of neem (Azadirachta indica) has been recorded. The disease predominated during the month of July-August. The average occurrence of the disease ranged between 3.8 to 26.0 per cent. Laboratory study has been carried out to isolate and identify the pathogen infected A. indica ten provenances; Bargi provenance of A. indica was found more susceptible as compared to other provenances while Shahdol and Raigarh provenances showed relative resistance to disease.
