ABSTRACT

A total of 12 fluorescent Pseudomonas isolates collected from rhizosphere soils of healthy chickpea plants from six
districts of Andhra Pradesh were evaluated against chickpea Fusarium wilt pathogen i.e., Fusarium oxysporium f.sp. ciceris by dual culture technique. Significant differences in inhibition percentage were observed among the treatments. Maximum per cent inhibition was observed with CRP-6 isolate (58.32%) followed by CRP-8 (56.90%) and minimum per cent inhibition of 4.57 was observed in CRP-10 isolate.

KEY WORDS: Chickpea, fluorescent Pseudomonas, dual culture, Fusarium.
