Description

A kind of composition pesticide and application thereof

Technical field

The invention belongs to technical field of pesticide, relate to a kind of compounding agriculture being made up of ZEN 90160, diethofencarb and fluoridamid Drug composition and application thereof.

Background technology

ZEN 90160 (picoxystrobin), chemical name: methoxymethylene-2-(3-trifluoromethyl-2-pyridine oxygen Methyl) phenylmethyl acetate, CAS accession number: 117428-22-5, is a class low toxicity, efficient, the methoxy acrylic of wide spectrum Antibacterial, has protection, treats, roots out and permeability, for most of fungus-caused disease such as leaf blight, leaf rust, grain husk Rot, brown spot etc. have excellent results, do not have cross resistance with other the most conventional antibacterial, and can be at plant In, fast degradation in soil and water, to mammal low toxicity.

Diethofencarb (diethofencarb), chemical name: 3,4-diethoxy phenylcarbamic acid isopropyl esters, CAS logs in Number: 87130-20-9, diethofencarb be a kind of efficiently, wide spectrum new type bactericide that low toxicity, Environmental compatibility are good, to benzimidazole Antibacterial is negative cross resistance, has stronger interior absorption, is absorbed by root and leaf, has higher anti-for eliminating vegetable botrytis etc. Effect.

Fluoridamid (fluoridamid), chemical name: the first and second acyls are replaced benzene by 3 '-(1,1,1-trimethyl fluoride sulfonyl amido) Amine, CAS accession number: 47000-92-0, can serve as dwarfing plants agent, the growth of suppression plant stem, it is also possible to accelerate fruit Maturation also improves sugar content, also part weeds is had growth inhibitory effect.

The single use of diethofencarb long-term, high-dose can make and pathogen produces stronger Drug resistance, therefore at present in agricultural In production, diethofencarb uses with other pesticide activity component mixtures mostly, but pesticide activity component huge number, physics and chemistry Matter, action character etc. are different, and inappropriate compound scheme may result in and occurs chemical reaction to lose between active component Drug effect, it is also possible to the bad results such as poisoning can be caused.Therefore, how to select suitable farm chemical ingredients reasonably to compound, make It produces optimum efficiency is the problem during this area is still explored.

Summary of the invention

For the problems referred to above, the invention provides a kind of safe and effective farm chemical ingredients mixture scheme, by by pyridine oxygen bacterium Ester, diethofencarb and fluoridamid carry out mixture according to a certain amount so that each composition is the most collaborative, can not only remarkably promote plant Growth, improves fruit yield and quality, for can also be played the prevention effect of Synergistic by fungus-caused plant disease.

The invention provides a kind of composition pesticide, the weight ratio of its active component is: ZEN 90160: diethofencarb: increase sugar Amine=1 ~ 80:1 ~ 80:0.1 ~ 40；It is preferably: ZEN 90160: diethofencarb: fluoridamid=1 ~ 20:1 ~ 20:0.1 ~ 10；Further preferably For: ZEN 90160: diethofencarb: fluoridamid=1 ~ 10:1 ~ 10:0.1 ~ 4.

Composition pesticide of the present invention can add the auxiliary agent allowed on pesticide and be prepared as the common formulations of agriculture field, The dosage form of described composition pesticide can be water dispersible granules, aqueous suspension agent, wettable powder, cream, microcapsule suspending agent, water Agent, powder, granule etc..

According to the required kind difference preparing preparation, dispersant, wetting agent, emulsifying agent, antifreezing agent, bonding can be selected One or more in the common auxiliary agents such as agent, defoamer, preservative, coloring agent, solvent, carrier, the selection of concrete auxiliary agent kind Screening can be carried out according to practical situations such as active component content, use environment by normal experiment to determine.

Composition pesticide of the present invention can be used in preventing and treating common fungal plant disease, but highly preferred, uses In preventing and treating plant botrytis, particularly with solanaceous vegetables or pomaceous fruits fruit, can not only effectively prevent and treat fungal disease, moreover it is possible to Enough promote fruit growth, improve fruit quality.

The present invention can obtain following beneficial effect:

(1) by pesticide activity components different for the mechanism of action is carried out mixture, it is to avoid single component life-time service causes Drug resistance, works in coordination with between each composition each other, and compared with single component, prevention effect is greatly improved；

(2) plant growth regulator is used in mixed way with fungicide active ingredient, while plant is invaded and harassed by minimizing disease, strengthens Plant self disease resistance, improves plant health level further, improves yield；

(3) it is effectively improved nutrient substance distribution, increases the sugar content of fruit, significantly improve fruit quality.
