Biological control of root infecting fungi with Trichoderma harzianum

Trichoderma harzianum inoculum multiplied on different substrates viz. rice grain, sorghum grain, millet grain and sawdust were used in the control of root infecting fungi on chickpea and mashbean. This inoculum after multiplication on sorghum grain, millet grain and rice grain, as used @1 % w/w in soils showed better result in reducing infection of Macrophomina phaseolina and Fusarium spp. on chick pea and mash bean as compared to 5 % and 10 % inoculum multiplied on saw dust, which did not show better results.
