Abstract
The invention relates to the field of pesticide processing, and specifically discloses a clethodim emulsifiable pulvis. The composition and the content of the emulsified the pulvis are: 1% to 50% of clethodim, 1% to 20% of a wetting dispersant, 1% to 30% of an emulsifier, 0 to 10% of a solvent and the balance being a carrier. The clethodim emulsifiable pulvis is simple in preparation, convenient in application, less in environment pollution and safe in storage and transportation, and has equal efficacy with a clethodim emulsifiable concentrate, thereby being an ideal herbicide.
Description
Technical field
The invention belongs to pesticide processing field, relate to the novel form of agricultural herbicide clethodim, relating to particularly a kind of clethodim can emulsified powder.
Background technology
The chemical name of clethodim (clethodim) is: (±)-2-[(E)-1-[(E)-3-chloroallyloxyamino imino group] propyl group]-5-[2-(ethylmercapto group) propyl group]-3-hydroxyl hexamethylene-2-ketenes, be that inner sucting conduction type cauline leaf is processed weed killer herbicide, have good selectivity.Grassy weed is had to very strong lethal effect, to dicotyledonous crops safety.Be mainly used in preventing and kill off soybean, Rapeseed Field is annual and perennial grassy weed and the spontaneous cereal crop of broad leaf crop Tanaka are spent more moleplant seed, Bermuda grass, fossilia dentis mastodi thatch, amur foxtail, foreign wild knotweed, eleusine indica etc. as barnyard grass, lady's-grass, annual bluegrass, wild oat, green foxtail, setaria glauca, faber bristlegrass herb.To dicotyledon, nutgrass flatsedge activity is very little or non-activity.
The main preparation formulation of clethodim application is at present missible oil.Although missible oil good drug efficacy, it is relatively easy, easy to use to prepare, and contains a large amount of toluene, dimethylbenzene or solvent wet goods organic solvent in missible oil, and environmental pollution is serious, in the processes such as production, storage, transportation, all has hidden danger.Therefore, be necessary to develop a kind of environmentally friendly, herbicidal effect good, and clethodim novel form high to crop safeties such as soybean, rapes, use cost economy, to meet the needs of agricultural production.
Summary of the invention
Can emulsified powder be a kind of novel form growing up on the basis of missible oil, so far there are no, and clethodim can the dosage form research of emulsified powder and the report of application thereof.Inventor of the present invention is devoted to the research that clethodim can emulsified powder, and its object is: provide a kind of safety, environmental protection, stable storage, clethodim that herbicidal effect is good can emulsified powder.
Inventor select can with clethodim be mixed wetting dispersing agent, emulsifier, solvent and the carrier of processing, by a large amount of formulatings and performance test, test, obtaining a kind of clethodim satisfactory for result can emulsified powder, thereby has completed the present invention.
Technical scheme of the present invention is as follows: a kind of clethodim can emulsified powder, contains the upper acceptable auxiliary agent of active ingredient clethodim and agricultural and carrier, and wherein each component and weight percentage thereof are:
The present invention further preferred technical scheme is, composition and content thereof that clethodim can emulsifier are as follows:
Above-mentioned clethodim can emulsified powder in formula:
Described wetting dispersing agent is selected from the sodium salt (dispersant D425) of sodium lignin sulfonate, calcium lignosulfonate, naphthalenesulfonic acid-formaldehyde condensate (dispersant NNO), methyl naphthalene sulfonate formaldehyde condensate (Dispersant MF) or alkyl naphthalene sulfonic acid condensation polymer; More preferably wetting dispersing agent is selected from sodium salt or the methyl naphthalene sulfonate formaldehyde condensate of sodium lignin sulfonate, alkyl naphthalene sulfonic acid condensation polymer; Wetting dispersing agent can be selected from above-mentioned wherein one or more.
Described emulsifier is selected from calcium dodecyl benzene sulfonate (agriculture breast 500), the compound (agriculture breast 0201B) of solvent for anion and non-ionic surface active agent, alkyl phenol formaldehyde resin polyoxyethylene ether (Nongru-700), alkylphenol-polyethenoxy (15) ether (agriculture breast NP-15), phenethyl phenol polyethenoxy ether and vegetable oil polyoxyethylene ester admixture (OX-2681), phenethyl phenol polyethenoxy polyethenoxy ether (agriculture breast 1601), castor oil polyoxyethylene ether (agriculture breast BY110), alkyl phenyl APEO (agriculture breast 100), sorbitan monooleate (S-80), dibutyl naphthalene sulfonic acids calcium (agriculture breast 2201) or castor oil polyoxyethylene (40) ether (agriculture breast EL-40), more preferably emulsifier is selected from compound (agriculture breast 0201B), alkyl phenol formaldehyde resin polyoxyethylene ether (Nongru-700), phenethyl phenol polyethenoxy polyethenoxy ether (agriculture breast 1601), castor oil polyoxyethylene ether (agriculture breast BY110), alkyl phenyl APEO (agriculture breast 100), dibutyl naphthalene sulfonic acids calcium (agriculture breast 2201) or castor oil polyoxyethylene (40) ether (agriculture breast EL-40) of solvent for calcium dodecyl benzene sulfonate (agriculture breast 500), anion and non-ionic surface active agent, emulsifier can be selected from above-mentioned wherein one or more.
Described solvent is selected from solvent naphtha, cyclohexanone, 1-METHYLPYRROLIDONE, dimethylbenzene, toluene or DMF; More preferably solvent is selected from dimethylbenzene or solvent naphtha.
Described carrier can be selected from diatomite, white carbon, potter's clay, precipitated calcium carbonate, bentonite, kaolin or attapulgite; More preferably carrier is selected from white carbon, bentonite or attapulgite; Carrier can be selected from above-mentioned wherein one or more.
Clethodim of the present invention can adopt following two kinds of methods processing preparation by emulsified powder.A kind of method is: after active ingredient in first filling a prescription (being the former medicine of clethodim) mixes with liquid adjuvants component, be adsorbed on carrier, mix with other solid constituent again, then by airslide disintegrating mill, pulverize, make granularity reach 98% and sieve by 45 μ m; Another kind method is: first the carrier in formula and solid matter are crushed to granularity and reach 98% and sieve by 45 μ m, then the former medicine of the clethodim mixing, solvent and liquid adjuvants are evenly adsorbed on it.The clethodim of the present invention of preparing by above-mentioned two kinds of methods can emulsified powder, and the performance of its product is not affected by preparation method all.
Clethodim of the present invention can directly be watered the rear spraying use of dilution by user by emulsified powder before use, its active ingredient reaches emulsified state in water, clethodim drug effect is not fully exerted, its drug effect effect is suitable with missible oil, thereby has solved the technical barrier that all the time can only use this puzzlement of missible oil formulation people.This can emulsified powder stable performance simultaneously, and heat storage (54 ± 2) ℃ is placed 14 days, and active ingredient resolution ratio is less than 10%.Clethodim of the present invention can have good activity of weeding by emulsified powder, can be used for preventing and kill off barnyard grass, lady's-grass, green foxtail, paddy green bristlegrass, reed, hard grass, eleusine indica, wild oat, amur foxtail, Alopecurus, deceive grass, moleplant seed, nit grass, lolium temulentum, caput grass, annual bluegrass, broomcorn millet, wild broomcorn millet, Texas millet, arm shape grass, Bermuda grass, fossilia dentis mastodi thatch, quackgrass, awns barnyard grass, red rice, Rottboellia exaltata, Radix seu Herba Astilbes rivularis, false Chinese sorghum, racemosus muhly, the multiple grassy weed such as spontaneous corn, be specially adapted to prevent and treat soybean, cotton, peanut, grassy weed in Rapeseed Field.
Clethodim of the present invention can have the following advantages by emulsified powder: 1, in formula, need not or only use a small amount of organic solvent, both save a large amount of organic solvents, avoided organic solvent harm to people and environment when producing and use, can improve again the safety of production, storage, transportation; 2, preparation is can emulsified powder biologically active high, and safety is good, and drug effect and clethodim EC are suitable; 3, preparation method is simple, and good product mobility is non-caked, do not lump; 4, product storage performance is good.
