Abstract

Laboratory experiment was conductcd to study the compatibility of 1 hiamethoxam 70WS with growth and sporulation of Trichoderma harzianum. There wn no inhibition of mycelial growth of T. harzianum in all the concentrations except at 1.25 percent. The spore count was 1xl0⁴ spores/ ml at seven days after inoculation of Trichoderma. The reduction in the radial growth of Rhizactonia solani was 40.2 percent in presence of T. harzianum whereas no inhibition was observed In thiamethoxam at 10g/kg seed. In combination with thiamethoxam at 2,85g/kg seed+Trichoderma, 4.28g/kg seed+Trichoderma and l0g/kg seed+Trichoderma, the reduction in radial growth of R. solani was 37,3, 35,95 and 32.4 percent, respectively. The study indicated that it is possible to use Trichoderma @ 4g/kg seed and thiamethoxam l0g/kg seed as seed treatment, which find a place in the integrated insect pest and disease management.
