Description

It is a kind of to eliminate propargite on citrus using the propargite preparation for generating phytotoxicity

Technical field

The invention belongs to pesticides application fields, are related to propargite mite killing on citrus and solve using the technology of produced phytotoxicity Scheme and preparation method.

Technical background

Propargite (Propargite), chemical name: the bright base sulfurous acid of 2- (4- tert-butyl benzene oxy) cyclohexyl propyl- 2- Ester, be it is a kind of efficiently, low toxicity, broad spectrum activity organosulfur acaricide, have it is stronger tag and stomach poison function, can be widely used for preventing and treating Cotton, citrus, apple fruits and vegetables, tea, flowers and other crops harmful mite, introduce China prevent and treat mite class nearly 20 years.Propargite has choosing Selecting property, safer to honeybee and natural enemy, residual effect is lasting, and toxicity is very low, small to people and animals and natural environment harm, is integrated control Ideal acaricide, lasting period are 14~30 days.

Due to efficient, less toxic, wide spectrum, cheap and do not developed drug resistance using more than 30 years in the world, thus alkynes mite Spy is extensively received by the market always as acaricide.

Propargite is all effective at any temperature, but effect is more significant in hot weather, because of temperature When higher than 27 DEG C, propargite, which has, tags and fumigates double action.It is especially used in megathermal period mite class difficult anti-season, contrast effect is more Add significant.

Propargite is as acaricide common in the market, and registering dosage form at present is missible oil and aqueous emulsion, but according to market tune It looks into and feeds back, there is the drug injury problems different degrees of to citrus in summer use for both products, therefore the product is current It can only be used after autumn and winter harvesting as the clear garden medicament of citrus.

According to citrus research institute, the Chinese Academy of Agricultural Sciences the study found that propargite not only has phytotoxicity to citrus spring tip tender leaf, but also Under summer high-temperature environment, if excessive using excessive concentration or dosage on fruit, fruit face can be made to generate yellow item Shape or irregular ring grain, influence fruit appearance.

Missible oil is a kind of common formulations of pesticide, is mainly made of pesticide active ingredient, organic solvent and emulsifier, is one The clear solution of kind homogeneous stability, is watered the lotion that can form milk shape.Missible oil has easy processing and easily storage, good drug efficacy etc. Advantage.

Aqueous emulsion, a kind of uniform emulsus formulations of pesticide of water baseization, entering water can be very good to be dispersed into uniform emulsion, Mainly it is made of pesticide active ingredient, emulsifier and water.

Emulsifiable pulvis and a kind of formulations of pesticide, mainly by pesticide active ingredient, adsorbent, emulsifier and filler group At being a kind of uniform flowable powder formulation of appearance, can preferably emulsify, disperse in water, form metastable emulsus Liquid.

Summary of the invention

The purpose of the present invention is to provide a kind of propargite preparations, can eliminate propargite on citrus using the medicine generated Evil.

It is a kind of to eliminate propargite on citrus using the propargite preparation for generating phytotoxicity, it is characterised in that the propargite The dosage form of preparation is emulsifiable pulvis.

Further, the propargite preparation contains active constituent propargite 5%-40%, adsorbent 5%-30%, surface Activating agent 5%-15%, anti-transpiration component 5%-40%, surplus is filler；Wherein, percentage is weight percentage.

The anti-rising group is selected from hexadecanol emulsion, vinyl chloride docosanol, terpene resin, glyceride, 2- hydroxyl Base -4- methoxy benzophenone, butylmethoxydibenzoylmethane, phenyl benzimidazole sulfonic acid or Uvinul T 150 One of or it is a variety of.

The adsorbent is diatomite, attapulgite, white carbon black, light calcium or kaolin (2000 mesh).

The surfactant includes serving as emulsifier, wetting agent, dispersing agent, synergist etc., be can be non-ionic And anionic, be also possible to two or more compound uses.The emulsifier is selected from neopelex, 12 Alkyl benzene calcium sulfonate, castor oil polyoxyethylene ether, fatty alcohol polyoxyethylene ether, Fatty alcohol polyoxyethylene polyoxypropylene ether, benzene second Alkene phenol polyethenoxy ether, styrenated phenol polyoxyethylene ether polyethenoxy ether or phosphoric acid ester APEO triethanolamine salt etc.；Institute Dispersing agent is stated to connect selected from naphthalene sulfonic acid condensate sodium salt, calcium lignosulfonate, sodium lignin sulfonate, polymeric polycarboxylic acid salt, rosin Branch block copolymer or styrene acrylic copolymer sodium salt；The wetting agent is selected from lauryl sodium sulfate, dibutyl naphthalene sulphur Sour sodium or fatty alcohol polyoxyethylene ether；The synergist is selected from aliphatic amine polyoxyethylene ether, coconut oleoyl amine polyoxyethylene ether, tea Saponin or fatty acid glyceride, above-mentioned surfactant account for the 5%-15% of propargite preparation compositions weight ratio.

The filler is soluble inorganic salt or other filler materials, preferably anhydrous sodium sulfate, sodium tripolyphosphate, carbon Sour ammonium, ammonium sulfate, ammonium chloride, sodium benzoate, urea, one of soluble starch or two or more mixtures.

In the above-mentioned emulsifiable pulvis that can eliminate propargite citrus phytotoxicity, removes and contain active constituent and function ingredients, suction Attached dose, surfactant and carrier (filler) are outside, it may also be necessary to solvent, stabilizer, coloring agent etc. be added.

The solvent is solvent naphtha, N-Methyl pyrrolidone, decyl amide, one or both of sec-butyl acetate.

The stabilizer is oleic acid, polyethylene glycol, epoxidized soybean oil, sodium benzoate, epoxychloropropane etc..

Coloring agent can be contained in preparation, such as azo dyes or kiton colors.

In the present invention, the dosage form of propargite preparation is emulsifiable pulvis, has miticidal effect good, at low cost, easy to produce, right The features such as citrus safety is good.

The present invention is using products such as common on the market 73% propargite missible oil and 40% propargite aqueous emulsion, and summer is in honey Tangerine prevents and treats red spider on the citruses such as Jiangxi orange, and under preferable preventive effect, discovery propargite can burn under 30-37 DEG C of high-temperature condition Tender tip blade face and fruit ultimately cause fruit blackspot, influence fruit quality.

Compared to traditional propargite missible oil and aqueous emulsion, the present invention can safely carry out at a temperature of 30-37 DEG C of summer Foliar spray, and traditional missible oil will not be generated on blade face and fruit or phytotoxicity that other dosage forms are be easy to cause, it greatly improves The safety that propargite uses under high temperature environment is a kind of ideal propargite citrus phytotoxicity technical solution.

The processing technology and equipment of the emulsifiable pulvis of invention formulation are known to disclosure.
