Ternary compound herbicide composition and application thereof to prevention and control of Chinese fir forest weeds

Abstract

The invention discloses a ternary compound herbicide composition and application thereof to prevention and control of Chinese fir forest weeds. The herbicide composition is prepared by taking prometryn, haloxyfop-R-methyl and sulfentrazone as effective components according to the weight proportion, wherein the mass ratio of the prometryn to the haloxyfop-R-methyl to the sulfentrazone is (1-100):(1-30):(1-100); the chemical name of the prometryn is N,N-diisopropyl-6-methylmercapto-1,3,5-triazine-2,4-diamine; the chemical name of the sulfentrazone is N-(2,4-dichloro-5-(4-difluoro methyl-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazole-1-yl)phenyl)sulfonamide. Three herbicide components with different action mechanisms are adopted, the weed control spectrum is wide, the prevention effect is obviously improved, broadleaf weed and grassy weed can be prevented and controlled, the weed control time is long, the safety of Chinese fir is guaranteed, and the problems of high manual weeding cost, lowefficiency and high damage to seedlings by herbicide harm in the weeding link in the process of nourishing young Chinese fir by people are effectively solved.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and in particular relates to a three-component compound herbicide composition of proturazin, high-efficiency haloxyfop-pamide and sulfentrazone and its application in the prevention and control of weeds in Chinese fir woodland. Background technique

[0002] Chinese fir, also known as: sand wood, sand tree, etc., belongs to the order of pines and cypresses, and is a tree of the family Firaceae; fir wood is widely used, and the demand for papermaking, furniture, construction, etc. is huge. Planting, the planting area is more than 9 million hectares. During the planting process of Chinese fir, overgrown weeds restricted its growth. But Chinese fir is more sensitive to most herbicides, such as glyphosate, glufosinate, fluroxypyr and so on. Therefore, at present, tending and weeding of Chinese fir young forests is mainly done by manual cutting or bagging directional application of glyphosate, whi...

Examples

Embodiment 1

[0029] Example 1 Promezazin: high-efficiency haloxyfop: sulfentrazone (10:3:10) suspension

[0030] Promethazine 10%, Haloxyfop 3%, Sulfentrazone 10%, Alkylphenol Polyoxyethylene Ether 8%, Polyoxyethylene Polyoxypropylene Block Compound 10%, Xanthan Gum 1% , water make up 100%. According to the above formula, weigh each material, mix these materials evenly through high-speed shearing, and then grind the balls in a ball mill for 2 to 3 hours to make the particle size meet the standard requirements, and then get 10% procytine · high-efficiency Flupyroxyfop · Sulfentrazone Suspension Concentrate.

Embodiment 2

[0031] Example 2 Promezazin: High-efficiency haloxyfop: Sulfentrazone (8:2:8) suspension
