Pigeon pea Fusarium wilt: In vitro pathogenicity test of Fusarium isolates and its biological control

Fusarium udum L. (Butler) is the causal agent of a wilt disease on pigeon pea (Cajanus cajan L.) and cause huge economical loss by destroying half or complete plant. An experiment was conducted to isolate and check the pathogenicity of Fusarium strains isolated from the wilted Redgram plant. The results revealed that the isolate RGF1 has shown significant amount of disease incident in pre emergent and post emergence of plant. Further studies were carried out to control the wilt disease incident through the help of biocontrol agents isolated from rhizosphere soil of Redgram. The results shows that the treatment which includes consortium of microorganisms had controlled significant amount of disease incident.
