Enhanced herbicidal triazine compositions and method of use

摘要

The herbicidal action of a herbicidal triazine upon weeds is enchanced upon also applying to the weeds a second herbicidal component, a butyl or pentyl glycol sulfonate or glycol sulfamate having 3, 5 or 3 substituted phenyl in the 2-position of the butyl or pentyl chain. The glycol sulfonate or sulfamate also adds its own herbicidal action to increase effectiveness. Both components are applied simultaneously as a novel composition which may also contain crop oil or crop oil concentrate. Application is made post-emergently before weeds reach about the 8 leaf stage. Advantageously, in an additional step, triazine alone or in combination with at least some of the sulfonate or sulfamate is also applied at planting or very early postemergently prior to the treatment described.
