1,2,4-Triazoline-5-one herbicides for galium species - give good control of resistant weeds in cereal and sugar beet e.g. the 3-benzyl-4-para methoxyphenyl cpd.

摘要

Herbicide compsn. for control of weeds, esp. Galium ssp., contains 3-R1-4-R2-1,2,4- triazoline-5-one of formula (I) as active cpd., with diluents, supports, vehicles and/or classical formulation additives (where R1, R2 independently are H or alkyl, aryl, aralkyl or cycloalkyl all opt. substd. by gp(s) such as halo, hydroxy, alkoxy, aryloxy, alkylthio, arylthio or amino (opt. substd. by alkyl and/or aryl gps.)). Pref. the individual ingredients of the compsn. are mixed immediately prior to use ("tank mix") and opt. diluted with water. Herbicide compsn. which is effective for control of Galium ssp. (catchweed) and is partic. useful for control in cereal and sugar beet crops. The selectivity and/or synergistic activity of (I) may be increased by use in combination with other herbicides.
