Influence exerted by four pesticides, viz., bavistin, captafol, thiram and BHC on VA-mycorrhizal endophyte, Glomus fasciculatum, in pearl millet has been quantified. Thiram application exerted most inhibitory effect on plant growth and mycorrhizal density in the roots, while captafol and bavistin reduced the total dry matter production of roots and shoots. Application of pesticides also adversely affected nutrient transport (N, P and K) in the host plants. The plants inoculated with G. fasciculatum alone exhibited positive response in all the test parameters observed as compared to uninoculated controls.
