Mycoparasitism of Trichoderma Spp. on Rhizoctonia Bataticola, the Causal Agent of Dry Root Rot of Chickpea.

ABSTRACT

Mode of parasitism between Trichoderma and Rhizoctonia bataticola was examined under a microscope. Formation of several loops and coiling around the hyphae of pathogen, forming a thick compact rope like structure followed by rupturing, twisting and leakage of hyphal protoplasm, air bubbling inside the cytoplasm, breaking of cytoplasmic continuity, aggregation of cytoplasm within cell leading to severe vacoulation were observed at later phase of interaction.
