Mixed herbicide containing glufosinate ammonium

Abstract

The invention discloses a mixed herbicide containing glufosinate ammonium, picloram and triklopir. Glufosinate ammonium, picloram and triklopir are effective components; a mass ratio of glufosinate ammonium to picloram to triklopir is (5-50) to (5-50) to (10-20). The mixed herbicide can be used for weeding woodlands or non-cultivated lands, especially has remarkable effect in application of prevention and removal of undershrub, gramineous weeds and broadleaf weeds planted in woodlands or non-cultivated lands. Compared with a single preparation, the herbicide is capable of improving weed resistance under the condition that the herbicide effect is improved, and is wide in herbicide spectrum and long in preserving effect period.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a three-component compound of glufosinate-ammonium, picloram and triclopyr. The herbicide composition can be applied to forest land and non-arable land for weeding. Background technique

[0002] Picloram (Picloram), chemical name: 4-amino-3,5,6-trichloropyridinecarboxylic acid, structural formula as follows:

[0003]

[0004] Picloram is a systemic and selective herbicide with plant growth regulation effect, mainly acts on nucleic acid metabolism, deforms the structure of chlorophyll and other organelles, interferes with protein synthesis, acts on meristem activities, etc., and finally causes Plant death, mainly used for weeding in wheat fields, harmful to most broad-leaved crops, when crop rotation stubble, the impact of residual picloram on broad-leaved crops (beans, cotton, vegetables, tobacco, etc.) should be considered, therefor...
