Organophosphate are the esters of alcohols with phosphoric acid with some other acids .They are highly active with bio-degradable compounds viz. can be used in field at lower doses. The systemic approach for generating complete information on spread and intensity of resistance in each case, crop resistance pattern, mechanism and management of resistance is normally...
