IMPACT OF PESTICIDES ON AMF SPORE POPULATION AND DIVERSITY IN BANANA (MUSA SPP.) PLANTATION SOILS

ABSTRACT

Impact of pesticides on arbuscular mycorrhizae fungi (AMF) was carried out in banana plantation soils at Lalapet, Karur District. Maximum number of twenty two species of AMF population were isolated and identified from the soil of natural site without pesticides sprayed soils with moderate pH, high soil organic carbon, nitrogen and potassium, least available phosphorus content as compared to artificial site contaminated with pesticide and only seven species of AMF population were isolated from this soil. The present study would help to determine to what extent and which soil environment variables affects the density and abundance of AMF associations in banana plantation soils. 

Key words: AMF population, Banana plantation soil, Symbiotic association.
