Abstract:

Present investigations were undertaken to screen Grass pea germplasm for their resistance against powdery mildew in field condition & to test the efficacy of fungicides in vitro. The sixty Grass pea genotypes screened under natural field condition for the disease reaction against powdery mildew. The Experimental results revealed that elven genotypes including check RLK-279 were highly resistant, while twenty-four showed resistant reaction, sixteen were moderately resistant, and nine were moderately susceptible including susceptible check BioR-231 and none of the genotypes has shown susceptible and highly susceptible reaction (SR). The in-vitro studies revealed that, Tridemorph or Hexaconazole has inhibited the growth of E. pisi significantly. Thus, spraying of Tridemorph significantly managed powdery mildew disease caused by E. pisi in Grass pea with yield enhancement.
