Abstract

Seed germination, seedling morpholog and ‘)tlier parameters were studied in Maize cv. NAC - 6002, under the wet treatment of insectide - Gaucho & tungici& - Apron I sing different concentrations of recommended, below recommended, above re: om mended and in mu hination dosages of both the pesticides at exposure peroids of 12, 24 k 48 hrs. lioth Gaucho k. Apron had severely affected on germination and seedling growth (root lerixth, .,hoot L'cu±.;111) at longer e\ posu re period of all the concentrations. Lower concentrations of lower exposure period did not induce much hange on germination and other parameters, but higher doses of both the pesticides at allthe exposureperoids have been noticed.
