Abstract

The invention relates to a composition of chitin and avermectin or emamectin benzoate for insecticide and acaricide, and is characterized in that the dosage form of the compound preparation is microemulsion and the weight percentage of effective components in the compound preparation contains 0.5 to 10 percent of the chitin, 0.2 to 2 percent of the avermectin or 0.2 to 1.5 percent of the emamectin benzoate, with the rest of an auxiliary agent, a cosolvent and water. The pesticide preparation of the invention has no public pollution and can be applied to prevention of pests and mites in agricultural production, in particular to the prevention of plant nematode diseases.

Description

The insecticide acaricide composition of chitin and Avermectin or first dimension salt
Technical field
The present invention relates to a kind of agricultural insecticidal, kill the mite novel formulation, specifically contain chitin and Avermectin or first and tie up the desinsection of salt composition, kill the mite microemulsion.
Background technology
Chitin (Chitin) has another name called chitin, chitin etc., and outward appearance is white translucent chip solid, water insoluble, diluted acid and diluted alkaline.Become chitosan behind the de-acetyl chitin, have another name called shitosan (Chitosan), water insoluble and dilute alkaline soln, but dissolve in most diluted acids, claim soluble chitin again; Chitin or shitosan can get chitin soluble in water through some reaction, also claim water-soluble chitosan.
At present agricultural goes up the chitin that uses and mainly contains soluble chitin and water-soluble chitosan, the latter at plant immune adjusting, inducing anti-disease, induce the root of the crop cell mitogenetic and do to have better physiologically active aspect deposits yields chitinase dissolving nematode body wall and the chorion control nematode by inducing.Water-soluble chitosan must not add the chitin water soluble liquid that organic or inorganic acid can be prepared high level, and with chemistry or Biocidal, miticide good compatibility stability is arranged.Though water-soluble chitosan tentatively is used for agricultural production as nuisanceless anti-nematode agent,, must use in advance and preventive effect factor such as have much room for improvement is failed penetration and promotion because its use cost is higher.
Avermectin (Abamectin) is the macrolides Biocidal miticide that produces by the biofermentation bacterial metabolism.Pure product are white crystal, are dissolved in alcohol, ketone, ester isopolarity organic solvent, and are water insoluble.Avermectin has desirable control efficiency to common insect, evil mite such as aphid, mite, diamond-back moth, plant hopper, trialeurodes vaporariorum, liriomyza bryoniae, pear sucker, root-knot nematode etc. on the agricultural.Important super-high-efficient Biocidal, miticide kind have been become.The emamectin-benzoate (first dimension salt) that is formed through structure of modification by Avermectin has been inherited the biologically active characteristics of Avermectin, and some refractories reason insects such as beet armyworm, nematode etc. are had higher biologically active and quick-acting.But Avermectin or first dimension salt all exist pest to its risk that develops immunity to drugs, and the control cost remains to be reduced.
Summary of the invention
The object of the invention is the deficiency that exists separately at chitin and Avermectin or first dimension salt, and a kind of efficient, wide spectrum, moderate, the nuisanceless desinsection that is difficult for developing immunity to drugs of cost, mite-killing preparation are provided.Said preparation can be used for the control of control, the especially nematode of agriculture common insect, evil mite.
Desinsection of the present invention, kill and to contain chitin and Avermectin or two kinds of active ingredients of first dimension salt in the mite microemulsion.Because there are many disadvantages in insoluble chitin and soluble chitin on solubility property and physiologically active, so the preferred water-soluble chitosan of the present invention.Water-soluble chitosan is promoting crop precocity, volume increase, is improving quality, obtaining very ten-strike aspect disease-resistant, the degeneration-resistant and Synergistic fertilizer, especially prevent and treat Plant nematode aspect and Avermectin or first dimension salt etc. and have diverse mechanism of action, between do not have cross resistance, and complementary synergistic effect is arranged.Water-soluble chitosan and Avermectin or first dimension salt is composite, can be from different perspectives, different aspect kills nematode, and control efficiency is subjected to the influence of spraying time less, produces delaying Avermectin or first dimension salt pesticide resistance, and it is very effective to improve integrated control effect.Microemulsion is to be the environment friendly agricultural formulation of medium with water, and active ingredient is biological insecticides in the preparation, therefore as the preferred microemulsion of the formulation of public nuisance-free agricultural chemicals preparation.
Desinsection of the present invention, the weight percentage that kills the mite microemulsion are as follows:
Chitin 0.5~10%
Avermectin 0.2~2%
Or first dimension salt 0.2~1.5%
Auxiliary agent, cosolvent, water add to 100%
The suitableeest weight percentage that provides product for the economic usability that improves product is as follows:
Chitin 3~6%
Avermectin 0.8~1.5%
Or first dimension salt 0.5~1.0%
Auxiliary agent, cosolvent, water add to 100%
Wherein the chitin as active ingredient can be former powder of water-soluble chitosan or mother liquor; Avermectin can be former powder or ointment, and first dimension salt can be the crude product of content 60~70% or the elaboration behind the recrystallization.Adjuvant used is to produce agricultural chemicals with known non-ionic monomer such as the newborn 600# of farming, Nongru-700, agricultural newborn 100# etc., it also can be the compound of nonionic and anion (as the newborn 500# of farming), also can add the wetting and penetrating agent that improves wetting, permeance property such as alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, penetrant t, azone etc., used cosolvent can be toluene, methyl alcohol, ethanol, isopropyl alcohol, n-butanol, cyclohexanone, N, one or more compositions in the dinethylformamide etc.Desinsection of the present invention, the preparation of killing the mite microemulsion or production method are microemulsion production methods commonly used, being about to Avermectin or first dimension salt dissolves with cosolvent, adding auxiliary agent stirs evenly, till mixing to clear with chitin water soluble liquid, promptly get chitin and Avermectin or first dimension salt microemulsion.
Advantage of the present invention:
1, reduced environmental pollution, production, storing safety have been improved, Avermectin and first dimension salt regular dosage form are missible oil, because the preparation effective content is generally 0.2~1.8%, in the preparation poisonous, inflammable benzene, alcohols solvent, and primary solvent is a water in the microemulsion, only contains a small amount of organic solvent, therefore more environmental protection, safer.
2, improved control efficiency and The comprehensive performance: active ingredient Avermectin or first dimension salt particle degree reaches nanoscale in the microemulsion, soup pest and plant leaf surface are had higher opening up, wetting, osmosis, effective rate of utilization increases substantially; Simultaneously the short length of chitin, lure anti-and synergistic effect to significantly improve the comprehensive function of product.Through field plot trial, 1000 times of liquid of 6% chitin aqua, in 2000 times of liquid irrigating root controls of 1.8% abamectin emulsifiable concentrate cucumber root nematode, 20 preventive effects are respectively 47.0% and 53.8% behind the medicine, and the preventive effect of 5.9% chitin, 2000 times of liquid of avermectin micro-emulsion (embodiment 1) dilution reaches 64.2%, promptly still has the highest preventive effect under the situation that Avermectin reduces by half.
