2-[4-(6-HALOQUINOXALINYL-2-OXY)PHENOXY]PROPIONIC ACID ESTERS, PRODUCTION THEREOF AND USE THEREOF AS HERBICIDES AND PLANT GROWTH REGULATORS

摘要

The invention relates to novel 2-¢4-(6-haloquinoxalinyl-2-oxy)phenoxy!propionates with herbicidal and plant growth regulating properties and having good selectivity in different crops of cultivated plants. The novel compounds have the general formula I < IMG > (I) wherein X is fluorine, chlorine or bromine, Z is oxygen or sulfur, A is a C1-C4alkylene bridge which is unsubstituted or substituted by methyl or ethyl, and R is C1-C4alkyl, with the proviso that the group -Z-A-COOR is other than -O-CH(CH3)-COOC2H5.
