Document Type and Number:
WIPO Patent Application WO1987007602
Kind Code:
A3
Abstract:
Aniline herbicides of formula (I), wherein R1 and R2 are hydrogen, halogen, alkyl, alkoxy or trifluoromethyl, phenoxy or benzyloxy, R3 and R4 are hydrogen, alkyl, alkenyl, alkynyl or halogen, Y represents hydrogen, halogen, cyano, nitrate, alkyl, alkenyl, alkynyl and various other substituents and Z is a heterocyclic group attached to the phenyl ring via a nitrogen atom which forms part of the ring system, or a carbocyclic or heterocyclic group attached via a nitrogen atom which does not form part of the ring system, exhibit excellent pre-emergent control of broadleaf weeds and grasses at rates as low as 0.25 lb/A with good safety to soybeans, cotton, corn and wheat. In post-emergent treatments these compounds show excellent and rapid control of broadleaf weeds with low (0-20 %) injury to soybeans, corn, wheat, and rice at rates as low as 0.015 lb/A. The compounds of this invention afford improved crop safety and control of grassy weeds. Novel aniline intermediates are used to make the anilides.
