Abstract
The invention discloses a cornfield herbicide used in the maturation stage of corns. The herbicide includes the following components in percentage by weight: 25-35% of a mixture of pyraflufen-ethyl and paraquat, 10-60% of an auxiliary and the balance of a filler, wherein the weight part ratio of pyraflufen-ethyl to paraquat is 1:50; the auxiliary is two or more of an emulsifier, a dispersing agent, a wetting agent, a spreader and a cosolvent; the filler is one or two of an organic solvent and water. The cornfield herbicide used in the maturation stage of corns, provided by the invention, has the advantages that the herbicide is a novel farm chemical which is efficient, targeted, environment-friendly, free of secondary poisonousness, non-residual, pollution-free, safe and capable of maintaining ecological balance, provides an important guarantee for realizing ecological agriculture, green ecological agriculture and green business, and has broad prospects.
Description
Technical field
The present invention relates to a kind of corn field weed killer herbicide for the maturing stage.
Background technology
Weeds can win honour for crops, strive fertilizer, strive aromatic hydrocarbons, and therefore farmland weed causes very large loss to production estimation every year.Therefore, it is very necessary for configuring a kind of efficient weed killer herbicide.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of free of contamination corn field weed killer herbicide for the maturing stage.
In order to solve above technical problem, the invention provides a kind of corn field weed killer herbicide for the maturing stage, comprise pyrrole grass ether and paraquat mixture that weight fraction is 25 ~ 35%, the auxiliary agent of 10 ~ 60%, other are filler; The ratio of weight and number of pyrrole grass ether and paraquat is 1:50; Described auxiliary agent is two or more in emulsifier, dispersant, wetting agent, spreader-sticker and cosolvent; Described filler is one or both in organic solvent and water.
The technical scheme that the present invention limits further is:
This corn field weed killer herbicide comprises pyrrole grass ether and the paraquat mixture that weight fraction is 20%, the auxiliary agent of 40%, and other are filler; The ratio of weight and number of pyrrole grass ether and paraquat is 1:20; Described auxiliary agent is emulsifier, dispersant and wetting agent; Described filler is organic solvent.
This corn field weed killer herbicide comprises pyrrole grass ether and the paraquat mixture that weight fraction is 10%, the auxiliary agent of 40%, and other are filler; The ratio of weight and number of pyrrole grass ether and paraquat is 1:40; Described auxiliary agent is emulsifier, dispersant and cosolvent; Described filler is water.
This corn field weed killer herbicide comprises pyrrole grass ether and the paraquat mixture that weight fraction is 25%, the auxiliary agent of 35%, and other are filler; The ratio of weight and number of pyrrole grass ether and paraquat is 1:35; Described auxiliary agent is emulsifier, dispersant, wetting agent, spreader-sticker and cosolvent; Described filler is in organic solvent and water.
To technique scheme further preferably, emulsifier is alkylphenol polyoxyethylene formaldehyde condensation products 700#; Described dispersant is polymeric carboxylic salt; Described wetting agent is dodecyl sodium sulfonate; Described spreader-sticker is CMC; Described cosolvent is polyvinyl alcohol; Described organic solvent is methyl alcohol.
The invention has the beneficial effects as follows: the corn field weed killer herbicide for the maturing stage of the present invention is a kind of high efficiency, specific aim, the feature of environmental protection, without secondary toxicity, noresidue, pollution-free, keep ecological balance, non-harmful novel agrochemical, realize the ecological agriculture, green ecological agricultural, the important guarantee of green enterprises, has bright prospects.
