Abstract

Pasting of the pruning wounds of grapevines with Tricho-XP, a commercial formulation containing Trichoderma viride and Paecilomyces lecanii, immediately after foundation pruning along with soil application @ 5 g/vine mixed with 245g cattle manure, and spray on the vines @ 1.0 % has shown the potential to reduce dead wood and enhance bud sprouting in Tas-A-Ganesh grapes. Further, five isolates of Trichoderma exhibited differences in their antagonism as well as ability to minimize dead wood formation and enhance bud sprouting. T. harzianum 5R exhibited maximum in vitro antagonism of Lasiodiplodia theobromae and was the most effective in minimizing dead wood formation in grapevines. This isolate was able to grow and inhibit radial growth of L. theobromae even at higher temperature of 36°C.
