Abstract
An aqueous emulsion containing acetochlor consists of the following ingredients by weight ratios: 5 to 70 percent of acetochlor,5 to 40 percent of organic solvent, 5 to 30 percent of emulsifying agent, 1 to 8 percent of anti-freeze agent, 0.5 to 5 percent of thickening agent, and the balance of water. The priority scheme is as follows: the aqueous emulsion contains 5 to 50 percent of acetochlor, 5 to 20 percent of organic solvent, 5 to 10 percent of emulsifying agent, 1 to 8 percent of anti-freeze agent, 0.5 to 5 percent of thickening agent, and the balance of water. The product is applied to help agricultural producer to eradicate weeds and has advantages of good weed eradication effect, convenient use, low toxicity for people and animals and environmental friendliness.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, relate to a kind of aqueous emulsion that contains Acetochlor specifically.Wherein contain Acetochlor 5-70% weight ratio, organic solvent 5-40% weight ratio, emulsifier 5-30% weight ratio, antifreeze 1-8% weight ratio, thickener 0.5-5% weight ratio, surplus are water; Priority scheme is for wherein containing Acetochlor 5-50% weight ratio, organic solvent 5-20% weight ratio, and emulsifier 5-10% weight ratio, antifreeze 1-8% weight ratio, thickener 0.5-5% weight ratio, surplus are water.Product of the present invention is applied to agricultural production merchant weeding, and herbicidal effect is good, characteristics easy to use, and low to the person poultry toxicity, environment amenable characteristics.
Technical background
Pesticide emulsion in water (EW) is a kind of pesticides new formulation; Be the water-fast solution that the former medicine of water-fast liquid state or solid-state former medicine is dissolved in the organic solvent gained; Be scattered in the water; A kind of environmentally friendly type pesticidal preparations that forms, its outward appearance is an opaque and white emulsion, is a kind of oil-in-water property (O/W) emulsion.In the eighties in last century, data and the patent report of developing aqueous emulsion abroad just arranged, have part aqueous emulsion agent commodity the beginning of the nineties.
Acetochlor (), have another name called standing grain anti-this.Be the nonirrigated farmland acetamide-group herbicides; Have characteristics such as safety, efficient, broad weed-killing spectrum, can be used for soybean, corn, peanut, cotton, rape, watermelon etc., generally began to produce preventive effect at dispenser 10-20 days; 30-60 days is the drug effect peak period, and the longevity of residure is 70-80 days.Can prevent and kill off lady's-grass, barnyard grass grass, green foxtail, amur foxtail, india lovegrass, eleusine indica, hard grass, ox chickweed, amaranth lamb's-quarters, Stellaria alsine Grim., a series of weeds such as kitchen garden.
Summary of the invention:
The purpose of this invention is to provide a kind of aqueous emulsion that contains Acetochlor.
Aqueous emulsion of the present invention contains effective ingredient Acetochlor 5-70%.
Aqueous emulsion of the present invention also comprises organic solvent, emulsifier, antifreeze, thickener, water.
To be selected from emulsifier in methyl alcohol, ethanol, toluene, xylol, acetone, cyclohexanone, the aqueous emulsion of the present invention be one or more blended emulsifiers in NPE, AEO, castor oil polyoxyethylene ether, polyoxyethylene carboxylate, phenethyl phenol polyethenoxy ether, APES, APES formaldehyde condensation products, calcium dodecyl benzene sulfonate, dodecyl benzyl dimethyl ammonium chloride, special OPEO, alkylaryl polyoxyethylene polyoxypropylene random ether, APES, coconut oil alkanolamide, polyoxyethylene stearic acid ester, polyoxyethylene stearic acid ester, lauric acid polyoxyethylene ester, lauric acid polyoxyethylene ester, AEO, fatty alcohol phosphate, aliphatic acid polyethenoxy ether, polyoxyethylene carboxylate, the aliphatic acid polyethenoxy fat altogether to organic solvent in the aqueous emulsion of the present invention, and content is 5-30%.
Antifreeze is one of ethylene glycol, polyethylene glycol, glycerine, urea in the aqueous emulsion of the present invention, and content is 1-8%;
Thickener is one of hydroxypropyl cellulose, hydroxyethylcellulose, xanthans, polyethylene glycol, polyvinyl alcohol, propyl cellulose, ethyl cellulose in the aqueous emulsion of the present invention, and content is 0.5-5%
Water is deionized water or distilled water in the aqueous emulsion of the present invention.The addition of water is for supplying 100%
Contain Acetochlor 5-70% weight ratio in the aqueous emulsion of the present invention, organic solvent 5-40% weight ratio, emulsifier 5-30% weight ratio, antifreeze 1-8% weight ratio, thickener 0.5-5% weight ratio, surplus are water; Priority scheme is for wherein containing Acetochlor 5-50% weight ratio, organic solvent 5-20% weight ratio, and emulsifier 5-10% weight ratio, antifreeze 1-8% weight ratio, thickener 0.5-5% weight ratio, surplus are water.Aqueous emulsion of the present invention is by the effective ingredient Acetochlor, and being aided with emulsifier, stabilizing agent, antifreeze, thickener is that solvent is processed through homogenize technology with water.Earlier use the organic solvent dissolution acetochlor tc, add then emulsifier evenly after, slowly add entry, do not stop stirring simultaneously, add antifreeze then, fully shear at clipper, add thickener at last and fully mix.
Aqueous emulsion of the present invention can use by common mode, like spraying.
Advantage of the present invention
Acetochlor aqueous emulsion of the present invention is compared with existing missible oil and is had the following advantages:
1, owing to do not contain or only contain poisonous on a small quantity, inflammable organic solvent, unassured prevailing exploded danger, and no unpleasant toxic odor is little to eye irritation, has reduced the pollution to environment, improved greatly producing storing and user's safety;
2, the water with cheapness is matrix, and manufacturing cost has the reduction of different amplitudes;
3, the requirement to packing container also can not show a candle to the missible oil harshness, can reduce packing cost;
4, warm blooded animal toxicity is reduced greatly,, good to plant with other agricultural chemicals and fertilizer miscibilty than missible oil safety.
The present invention to soybean weeds-control, have good, the easy to use characteristics of herbicidal effect, for the weeding of soybean field provides highly effective approach.
