Description
Technical field
The present invention relates to herbicide technology field, a kind of weeding containing caprylic acid and glyphosate and its salt is more particularly to
Agent composition and its application.
Background technology
It is single to be difficult to control the harm of various mixed raw weeds using certain herbicide.Therefore, the combination of herbicide is to mix
Increasingly cause the attention of people with/mixture.Important means of the combinations of herbicides in farmland weed chemistry prevention and control, in the crop fields
It is wide with bare place application.According to the fluoro- glyphosate of report pyrrole, drop acid-glyphosate, fluorine oxygen-four kinds of glyphosate and Mai Wei-glyphosate etc.
Combinations of herbicides shows that herbicide mixture can effectively prevent and kill off amur foxtail, ox chickweed, caput grass to the preventive effect of bare place weeds
Various bare place weeds such as He Wang grass.
Glyphosate is a kind of non-selective, noresidue steriland herbicide, highly effective to prennical root weeds, is used extensively
In rubber, mulberry, tea, orchard and sugarcane field.The main enolpyruvyl shikimene phosphate synthase suppressed in plant, so as to press down
Shikimene processed synthesizes protein and is interfered to the conversion of phenylalanine, tyrosine and tryptophan, causes Plant death.Grass
Sweet phosphine is to be transmitted to plant parts after cauline leaf absorbs, and can prevent and kill off unifacial leaf and dicotyledonous, annual and perennial, grass
The plant of the section more than 40 such as this and shrub.Glyphosate is combined and lost activity with the metal ion such as iron, aluminium quickly after burying, to soil
In the seed that hides and edaphon have no adverse effects, such as in intake human body, certain infringement can be also produced to human body.In view of
This, herbicide synergistic combination of the exploitation containing glyphosate is significant.
Caprylic acid, also known as caprylic acid, molecular formula are C8H16O2；Be widely present in nutmeg, lemon grass (Cymbopogon citratus), apple, coconut oil,
In grape wine, hops etc., being extracted from coconut oil with volatile fatty acid fractionating process can obtain caprylic acid.It is currently used primarily in system
Dyestuff, medicine, spices, plasticizer, lubricant, it is also possible to make preservative, bactericide etc..
Scientific and reasonable chemical herbicide mixture/mixed have expand herbicidal spectrum, improve herbicidal effect, reduce dosage,
The features such as reducing poisoning, reduce residual, the generation that delays and administers resistant weed with development, herbicide mixture/mixed is solution
Above mentioned problem it is most effective, have easily one of method.The current weeding group on caprylic acid and glyphosate-class herbicides mixture
Compound and application there is no report.
