Impact of pesticides-mycorrhia interaction on growth and development of wheat

Abstract

In the present study impact of five pesticides viz. G- 696, Bavistin, Thiram, Captan and Aldrin on VAM colonization, host growth and nutrient uptake of wheat has been quantified. Most of the test pesticides suppressed the plant height, total dry weight of root-shoot and mycorrhizal density of host plants as compared to VAM alone treated plants. Captan application exhibited most inhibitory effect on all the parameters followed by Thiram and Bavistin. The plant nutrients i.e. nitrogen, phosphorus and potash uptake was also significantly affected by the application of pesticides. © 376.
