Mixed herbicide containing glyphosate

Abstract

The invention discloses a mixed herbicide containing glyphosate, picloram and triclopyr. The glyphosate, picloram and triclopyr are taken as active ingredients, and the mass ratio of glyphosate to picloram to triclopyr is (5-50):(5-50):(10-20). The mixed herbicide disclosed by the invention can be used for weeding in forest land or non-arable land and particularly has an obvious effect in the application of controlling undershrubs, grassy weeds and broadleaf weeds in the forest land or non-arable land. Compared with a single dosage, the herbicide disclosed by the invention has the advantages that the weed resistance is delayed under the condition that the drug effect is improved, the weed control spectrum is wide, and the lasting period is long.

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 glyphosate, 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, therefore, the use...

Problems solved by technology

However, triclopyr has a single herbicidal spectrum and is ineffective against gramineous weeds. In addition, it has a large residue in the soil and is likely to cause phytotoxicity to the next crops or interplanted crops in forest land. Weeds and improved safety, triclopyr mixed with other herbicides

[0011] In addition to various weeds, woodland and non-cultivated land also contain a large number of naturally growing small shrubs. Generally, weeds grow luxuriantly, the plants are strong, and various shrubs are overgrown, blocking sunlight and competing for nutrients. , the current herbicides cannot fully and effectively control the occurrence of weeds and small shrubs in woodland and non-cultivated land, and the cost of manual weeding is high and the efficiency is low, which brings great difficulties to the control of weeds in woodland and non-cultivated land
