ANTIDOTE COMPOSITIONS COMPRISING UREA DERIVATIVES, PLANT GROWTH REGULATING COMPOSITIONS AND ANTIDOTED HERBICIDAL COMPOSITIONS, AS WELL AS PROCESS FOR PRODUCING UREA DERIVATIVES

摘要

Novel carbamide derivs. and their salts of general formula (I) are used as antidotes to diminish or counteract phytotoxicity caused by plant protecting agents or selected cpds. to promote plant growth. In formula (I): R = hydrogen or halogen atom; R1 = one or several nitrogen and/or oxygen atoms, opt. single or multiple substd. - 1-4C alkyl or alkoxy gps., or hydroxy gp. substd. heterocyclic or condensed heterocyclic gps.; R2 and R3 = hydrogen atom or 1-4C alkyl gps.; n = 0 or 1.
