Field experiments were conducted during the vegetative season of April-October 2008 and 2009 and fruiting season of October-April 2008-09 and 2009-10, to study the efficacy of Milastin K, a formulation containing Bacillus subtilis (KTBS), for the control of powdery mildew on grapes. Five to six sprays of Milastin K @ 1.0 ml l-1 (1.0 l ha-1), from 30-119 days after pruning at 7-22 days interval (depending on weather based disease risk) could effectively control powdery mildew on leaves and bunches in grapes and increase yield. The untreated control recorded PDI in the range of 4.00-82.13 during different seasons, Milastin K treatment significantly reduced PDI to 1.62-20.69. Under low to moderate disease pressure conditions, the efficacy of Milastin K in controlling powdery mildew was on par with sulphur 80 WG @ 2.0g l-1. Under high disease pressure condition, Milastin K was not so effective when used alone, but was effective when used in integration with fungicide sprays. Harvestable yield of 4.55 kg per vine was recorded in Milastin K while there was nil yield in untreated control. There was no phytotoxic effect of Milastin K on vines when it was sprayed at a dose up to 2.0 ml l-1.Keywords

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.Keywords
