Abstract

                                Simultaneous or sequential application of herbicides with insecticides and fungicides in a single cropping season can minimize the cost of application of herbicides economically. To avoid physical, chemical and biological incompatibility, compatibility studies are to be carried out to find out the suitability of a spray combination. With this view, compatibility of pretilachlor was studied by estimating the yield obtained in the treatments consisting of pretilachlor in combination with an insecticide (Monocrotophos) and a fungicide (Carbendazim). The results of the study revealed that there was no difference in grain and straw yield of rice in treatments which received application of pretilachlor alone and with monocrotophos and carbendazim indicating the compatibility of pretilachlor with pesticides.
