Problems solved by technology

[0006] At present, herbicides in woodland and non-cultivated land are limited by the age of weeds, and the herbicide spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds and small shrubs in woodland and non-cultivated land. Due to its high water solubility or long duration in the field, excessive dosage or uneven application, it is easy to cause residual toxicity to current crops or subsequent crops.

Abstract

The invention discloses a synergistic herbicidal composition containing triclopyr and picloram and use thereof. The herbicidal composition mainly contains triclopyr and picloram, wherein the mass ratio of triclopyr to picloram is 1-50:1-50. The synergistic herbicidal composition of the invention can be used for preparing herbicides for killing weeds in forest lands or uncultivated areas. Compared with single preparations, the herbicidal composition, on the premise of improving herbicide effect, has a broad herbicidal spectrum, acts for a long time, is safe for woods and afterculture crops, and particularly has an obvious effect of controlling undershrubs and broadleaf weeds in forest lands or uncultivated areas.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound of triclopyr and picloram. The herbicidal composition can be applied to weeding in woodland and non-arable land. Background technique [0002] Triclopyr (triclopyr), chemical name: 3,5,6-trichloro-2-pyridineoxyacetic acid, its chemical formula is: C 7 h 4 Cl 3 NO 3 . [0003] Triclopyr is a conductive herbicide, acting on nucleic acid metabolism, causing plants to produce excess nucleic acid, causing some tissues to transform into meristems, resulting in abnormal growth of leaves, stems and roots, depletion of storage substances, and embolization of vascular tissue Or burst, and the plant gradually dies. It can be rapidly decomposed by microorganisms in the soil. It is used to control weeds and shrubs in forest land and non-cultivated land, such as: lotus seedlings, mother-in-law, ferns, eupatorium adenophorum, a...
