Abstract

Malathion is a non-systemic broad spectrum organophosphate insecticide which is used for controlling sucking and chewing insects on fruits and vegetables. It has been analyzed that effects of different concentrations of malathion on yield and AMF colonization in Coriandrum sativum. It was found that, at recommended and low dosages, coriander does not show any significant reduction in yield and AMF infection percentage, but higher concentrations reduced yield and AMF infection percentage of coriander. After I sampling, the maximum AMF infection percentage was observed in Control and M ½ ND (62% and 52% respectively) and least was observed in M2ND (i.e., 38%). After II sampling, the AMF infection percentage decreased in MND (i.e., from 50% to 48%) and M2ND (i.e., from 38% to 36%) plants. In Control plants the AMF percentage increased from 62% to 68%, although M ½ ND also recorded a slight increase in AMF infection percentage from 52% to 54%. After III sampling, the maximum AMF percentage colonization was observed in Control (74%), M2ND (42%) treatment showed least AMF percentage colonization. Similar trend was also observed   after 95 days (IV sampling) i.e., maximum in Control (76%) and least in M2ND (48%).
