A potential Trichoderma viride strain CZTV-1 was screened against 15 fungal plant pathogens of which nine pathogens Diaporthe sp., Nectria haematococca, Fusarium sp., Aspergillus flavus, Lasidiplodia theobromae, Pseudofusicoccum adansoniae, Fusarium solani, Aspergillus niger and Fusarium brachygibbosum were isolated from groundnut; three pathogens viz., Alternaria alternata, Fusarium equiseti and Fusarium oxysporum were isolated from cumin; and three pathogens viz., Alternaria tenuissima, Chaetomium atrobrunnem and Alternaria porri were isolated from castor. In dual culture, T. viride (CZTV-1) significantly reduced the mycelial growth of pathogenic fungi which was the least (29.0%) for Fusarium sp. (CZC- 3) and which was the maximum (82.2%) for Aspergillus niger (CZGN-12) which was statistically on par with Fusarium solani CZGN-9 (80.7%). This Trichoderma viride isolate (CZTV-1) can be further exploited for commercial scale up as a biocontrol agent under localized climatic conditions of western Rajasthan.
