Abstract
A compounded preparation for preventing and eliminating weeds in farm and is composed of (by wt.%) effective ingredient metolachlor 10-30 and glyphosate isopropyl amine 20-40, and the rest being emulsifier calcium dodecyl benzene sulfonate, ricinous oil polyethenoxy ether 8-12 and water up to 100. Said agent possesses intussuscoption and conduction effects and lasting activity in soil, is broad in herbicidal spectrum, and possesses larger synergistic and complementary action. It can be used for eliminating weeds in cotton, soybean, corn, sorghum, peanut, cane etc. fields.
Description
The present invention relates to a kind of composition pesticide, relate in particular to a kind of isopropyl methoxalamine of farmland management of weeds and complex preparation of glyphosate of being used for.
Glyphosate (glyphosate) is interior suction conduction nonselective herbicide, mainly absorbs by cauline leaf, and conducts under ground portion, and protein synthesis is disturbed, and causes plant death.It kills grass and composes wider, double except that annual and perennial perennial root ruderal.Then, combine very soon after glyphosate buries, lose activity, therefore, exist in soil, not have to hold and imitate active defective with iron, aluminium plasma.
The purpose of this invention is to provide inhale conduction in a kind of the having concurrently and in soil, hold imitate active, kill careless spectrum width wide, have the agricultural chemicals isopropyl methoxalamine of big synergy complementation and a complex preparation of glyphosate.
Isopropyl methoxalamine (metolachlor) is the dry crop preemergence herbicide that Switzerland Novartis Co.,Ltd (NOVARTIS) develops.Main young shoot or bud scale by weeds absorbs, upwards conduction, and Profilin matter is synthetic, thereby suppresses the growth of weeds young shoot and root, causes weeds death.Can prevent and kill off annual single, double cotyledon weeds and nutgrass flatsedge, obvious especially to preventing and kill off effects such as annual gramineous weed such as barnyard grass grass, lady's-grass grass, green foxtail, eleusine indica, it has the closed soil activity, applied once, and the lasting period can reach 30 days.
The chemical structural formula of isopropyl methoxalamine is:
The chemical structural formula of glyphosate (glyphosate) is:
The pure product of glyphosate are non-volatile white solid, are insoluble to common organic solvents, and the solvability in the time of 25 ℃ in water is 1.2% (weight).The isopropyl amine salt of glyphosate is dissolved in water fully, and its activity of weeding is identical with glyphosate.
The chemical structural formula of glyphosate isopropyl amine salt is:
The present invention is achieved in that the complex preparation of a kind of isopropyl methoxalamine and glyphosate, it is characterized in that complex preparation is an emulsion, wherein effective ingredient is isopropyl methoxalamine (metolachlor) and glyphosate isopropyl amine salt (glyphosate-IPA), isopropyl methoxalamine is 10%～30% (weight), glyphosate isopropyl amine salt is 20%～40% (weight), and all the other add to 100% (weight) for emulsion and water.
Emulsifier among the present invention is to choose any one kind of them or several composite composition in calcium dodecyl benzene sulfonate, castor oil polyoxy ethyl ether, the common embedding thing of alkyl phenol polyoxy ethyl polyoxyethyl propyl ether, accounts for 8～12% (weight) of preparation.
All the other add to 100% (weight) for water in the component of the present invention.
The complex preparation of isopropyl methoxalamine of the present invention and glyphosate isopropyl amine salt is an emulsion, is used for cotton field, corn, soybean, the preceding no-tillage ground of peanut seeding, prevents and kill off grass family, broad-leaved and sedge weed.
Preparation process of the present invention be with the isopropyl methoxalamine in the above-mentioned prescription and glyphosate isopropyl amine salt and emulsifier in the emulsification pot, emulsification under normal temperature adds entry then and makes that to contain isopropyl methoxalamine be that 10%～30% (weight) and glyphosate isopropyl amine salt are the emulsion of 20%～40% (weight).
The present invention is mixed isopropyl methoxalamine and glyphosate isopropyl amine salt and forms complex preparation, have weeds concurrently and conduct and upwards conduct to the dual conduction function of stem, leaf from stem, leaf absorbable preparation to root from the root absorption preparation, it is dead to cause weeds to be accelerated, and has strengthened the killing effect to weeds.Said preparation has the closed soil activity, applied once, and the lasting period can reach 30 days.Said preparation also has the characteristics of broad weed-killing spectrum, the weeds of section more than 40 are prevented and kill off effect, comprise unifacial leaf and dicotyledonous, annual and perennial, vegetation and shrub are as annual gramineous weed and three-coloured amaranth, kitchen garden, broad leaved weed and cyperus irias etc. such as barnyard grass grass, eleusine indica, lady's-grass, green foxtail.Can effectively prevent and kill off the no-tillage ground of dry crop, fallow land and adopt the directed spraying technology to prevent and kill off the annual and perennial weeds in orchard, plantation, nursery.
Complex preparation of the present invention is used for dry crop and comprises the preceding no-tillage ground weeding of sowings such as cotton, soybean, corn, Chinese sorghum, peanut, sugarcane and Chinese cabbage, wild cabbage; Orchard and plantation, nursery directed spraying weeding; Forestry and fallow land afforestation weeding and safeguard the forest fire protection line.
It is embodiments of the invention: embodiment below: each component ratio (weight %) among the present invention
The listed prescription of the foregoing description is not the restriction to aforementioned each component proportioning of the present invention, but content of the present invention is described further.
The effective ingredient of the complex preparation among the above-mentioned embodiment 1-11 is isopropyl methoxalamine and glyphosate isopropyl amine salt, and emulsifier is to choose any one kind of them or several composite composition in calcium dodecyl benzene sulfonate, castor oil polyoxy ethyl ether, the common embedding thing of alkyl phenol polyoxy ethyl polyoxyethyl propyl ether.
Claims (4)
1, the complex preparation of a kind of isopropyl methoxalamine and glyphosate, it is characterized in that complex preparation is an emulsion, wherein effective ingredient is isopropyl methoxalamine (metolachlor) and glyphosate isopropyl amine salt (glyphosate-IPA), isopropyl methoxalamine is 10%～30% (weight), glyphosate isopropyl amine salt is 20%～40% (weight), and all the other add to 100% (weight) for emulsifier and water.
2, complex preparation according to claim 1, it is characterized in that described emulsifier be calcium dodecyl benzene sulfonate, castor oil polyoxy ethyl ether, alkyl phenol polyoxy ethyl polyoxyethyl propyl ether altogether the embedding thing choose any one kind of them or several composite composition, account for 8～12% (weight) of preparation.
