Description

A kind of macro tetrolide and the water dispersible granules of Hexythiazox and application
Technical field
The invention belongs to the water-dispersible of the technical field that agricultural chemical insecticide is compounding, a kind of macro tetrolide and Hexythiazox Granule and application.
Background technology
Macro tetrolide
By the antibiotic produced by the mutation of streptomyces griseus Liuyang with macrolide structure, for low toxicity, low-residual, Can prevent and treat the broad spectrum acaricides of the multiple mites of various crop, prevention effect is good.The tetranychid of various crop there is good tagging Effect, without interior absorption, medicament has lipotropy, if to becoming demodicid mite to have efficiently, does not kill Predatory Mites, and evil demodicid mite is not likely to produce resistance, kills Demodicid mite spectrum is relatively wide, the most effective to tetranychid, wart demodicid mite.Compound with some organophosphors or carbamate pesticide, have significant potentiation. Action of contace poison to evil demodicid mite, lasting period 7~14 days.
Physicochemical property: the mixture being made up of 5 components, four viable bacteria elements are main active component.Sterling is colourless Prism-shaped crystallizes, fusing point 112 DEG C~113 DEG C.Be soluble in benzene, ethyl acetate, chloroform, ether, acetone, dissolve in ethanol, just oneself Alkane etc. 50% solvent, water insoluble.To ultraviolet-sensitive, irradiating 2 days in the sun, decomposable asymmetric choice net 50% is with property percutaneous LDso > 2 000mg/kg.Character sterling is the crystallization of colourless prism-shaped.
Hexythiazox
Former medicine is light yellow or white crystals, and fusing point 108~108.5 ° of C, during 20 ° of C, vapour pressure is 338.6 × 10-8Pa, water Middle dissolubility is 0.5 mg/litre, and the dissolubility in the methanol of every 100 milligrams, hexane, acetone and other organic solvent is respectively 2.06 grams, 0.39 gram, 16.0 grams, preserve under 50 ° of C and do not decompose for 3 months.
If various plants evil demodicid mite is had strong ovicidal, kills the characteristic of children demodicid mite.Good to tetranychid preventive effect, to rust mite, wart demodicid mite Preventive effect is poor.Can be mixed with the Multiple Pesticides such as Bordeaux mixture, lime sulfur.Based on action of contace poison, plant tissue is had well Permeability, without interior absorption effect.Preventing and treating European red mite, if containing the phase of sending out children demodicid mite, when average every leaf has 3~4 demodicid mites, with 5% Cream or 5% wettable powder 1500~2000 times of liquid are sprayed.Before results, 7d stops using.
To people, animal low toxicity, eye is had minimal irritation effect, to birds low toxicity, to Apis non-toxic reaction under constant, right Natural enemy impact is the least, poisonous to Fish.If evil demodicid mite is had ovicidal, kills demodicid mite effect.
Currently, with respect to the compounding of macro tetrolide and Hexythiazox it is not yet reported that.
Summary of the invention
It is an object of the invention to provide a kind of has macro tetrolide and the water dispersible granules of Hexythiazox and application thereof, this combination Thing effective ingredient is macro tetrolide and Hexythiazox, and wherein the weight ratio of macro tetrolide and Hexythiazox is, macro tetrolide: Hexythiazox= 1:1-1:20, serves good synergistic function by compounding, reaches the purpose of cover crop, and can improve yield And quality.
The technical scheme is that
A kind of macro tetrolide and the water dispersible granules of Hexythiazox, effective ingredient is macro tetrolide and Hexythiazox, wherein Liuyang The weight ratio of mycin and Hexythiazox is, macro tetrolide: Hexythiazox=1:1-1:20.
As preferably, the weight ratio of macro tetrolide and Hexythiazox is, macro tetrolide: Hexythiazox=1:5-1:10.
The total weight percentage of described effective ingredient is 16~40%.
The macro tetrolide of the present invention and the water dispersible granules of Hexythiazox, consisting of by weight percentage following group Point:
Macro tetrolide 1-10%,
Hexythiazox 15-30%,
Hard water resistance dose of 3-4%;
Wetting agent 5-6%;
Dispersant 3-11%;
Disintegrating agent 9-14%;
Filler surplus.
Heretofore described hard water resistance dose is: in sodium tripolyphosphate, five polyphosphate sodiums, laminated crystal of sodium disilicate Kind.
Heretofore described wetting agent is: alkyl naphthalene sulfonic acid sodium salt, sodium lauryl sulphate, alkylaryl polyoxyethylene One or more in ether sulfate.
Heretofore described dispersant is: polyoxyethylene polyoxypropylene block copolymer, naphthalene sulfonic acid-formaldehyde condensation product sodium One in salt.
Heretofore described disintegrating agent is: one or more in anhydrous sodium sulfate, carboxymethyl starch sodium.
Filler of the present invention is: the one in white carbon, attapulgite, Pulvis Talci, bentonite.
The macro tetrolide of the present invention and the water dispersible granules of Hexythiazox, be used for preventing and treating veterinary antibiotics, Folium Camelliae sinensis, cereal crops Insect and evil demodicid mite, such as diamondback moth, thrips, flour mite, wart demodicid mite, be particularly suited for preventing and treating rice thrips.
The invention have the benefit that
Said composition is compound water dispersible granule compositions, has the feature of binary composition, significantly enhances effect, Delaying the generation of pest resistance to insecticide, and expand effective active preventing and treating spectrum, wherein the weight ratio of macro tetrolide and Hexythiazox is, clear Sun mycin: Hexythiazox=1:1-1:20, serves good synergistic function by compounding, reaches the purpose of cover crop, And yield and quality can be improved.And then, decrease the consumption of pesticide, also alleviate the impact for environment, meet following society The trend of meeting environmental protection, it is often more important that, this compounded combination has effectively resisted the problem that pest resistance produces, at utmost The problem alleviating current pest resistance to insecticide.
Compound synergic research to the compositions of the present invention, test uses rice thrips.
The toxicity index of medicament and mixed co-toxicity coefficient (CTC value) is calculated according to the abundant method of Sun Yun.
The table 1 different ratio relation toxicity test result to rice thrips
Process Co-toxicity coefficient
Macro tetrolide 1: Hexythiazox 1 310.5
Macro tetrolide 1: Hexythiazox 5 531.7
