Abstract
The invention discloses a pesticide combination. The pesticide combination comprises an active constituent A and an active constituent B, wherein the active constituent A is selected from etoxazole, and the active constituent B is selected from spirotetramat. The combination has obvious insecticidal efficacy and wide insecticidal spectrum, reduces the residuals on crops while the dosage is reduced, and is safe for the crops.
Description
Technical field
The present invention relates to a kind of synergetic pesticide composition, particularly a kind of synergetic pesticide composition that comprises second mite azoles and spiral shell worm ethyl ester and by this synergetic pesticide composition for preventing and treating the purposes of the mite class such as aphid, aleyrodid Panonychus citri, elm pawl tetranychid, beginning tetranychid, Tetranychus urticae, Tetranychus cinnabarinus of the crops such as fruit and vegetable.
Background technology
Mandarin tree, apple tree, vegetables etc. are important economic crops and the means of production, the mite classes such as aphid, aleyrodid, Panonychus citri, elm pawl tetranychid, Tetranychus urticae, Tetranychus cinnabarinus endanger them, after chemical pesticide is widely used in control of pest mite, its extent of injury is day by day serious, and become one of insect of these important crops productions of serious threat, for the expense of preventing and treating, also increase year by year.Each worm state (except ovum) of mite class all can endanger, and with mouthpart, punctures blade, green branch and fruit surface, and plant is endangered.Control mite class mainly depends on the chemical pesticides such as Hexythiazox, fenpropathrin, pyridaben, propargite for a long time.Because these mite classes easily produce resistance, so it has all produced resistance to most miticide in the market.Add that these agricultural chemicals are longer service life, dosage increases year by year, thereby causes occurrence frequency and the severity of harmful mite on these crops in rising trend.Raising along with rapid economic development and living standards of the people, people to the production of the green fruits and vegetables such as oranges and tangerines, apple, vegetables in the urgent need to when as far as possible reducing the production loss being caused by damage by disease and insect, the consumption of minimizing chemical pesticide and residual, keep the natural qualities such as oranges and tangerines, apple, therefore, develop new control medicament and seem very important and urgent.
Second mite azoles (etoxazole), chemical name is (RS)-2-(2,6-difluorophenyl)-4-(2-ethyoxyl-4-tert-butyl-phenyl)-4,5-dihydro-1,3-oxazoline, SUMITOMO CHEMICAL KCC in 20th century the mid-80 exploitation commercial 2 in 1998,4-dimethylbenzene-1,3-oxazoline class insecticidal/acaricidal agent.Second mite azoles has remarkable preventive effect to mite classes such as the Panonychus citri of the crops such as oranges and tangerines, elm pawl tetranychid, Tetranychus urticae, Tetranychus cinnabarinus.Its mode of action is that the embryo who suppresses mite ovum forms and the process of casting off a skin from young mite to one-tenth mite, effective to ovum and young mite, to becoming mite invalid.Therefore the control time of its best is the evil mite harm initial stage.Environmentally safe, to useful insect and beneficial mite without harm or endanger minimum.
Spiral shell worm ethyl ester (spirotetramat) is tetronic acid compounds, that Beyer Co., Ltd obtains formal registration in June, 2008, this composition is simultaneously by pest management office of Her Majesty the Queen in right of Canada as represented by the minister of Healt and Austria's health and food security office joint review, and Austria is the EU member country that serves as data review.Spiral shell worm ethyl ester has unique.Function Characteristics is one of modern insecticide having so far two-way interior suction conductive performance.This compound can upwards move down in whole plant corpus, arrives at blade face and bark, and the interior absorption of this uniqueness can be protected newborn stem, leaf and root, the ovum of pest control and larval growth; Its another feature is that the holding effect cycle is long, and the effective control that reaches 8 weeks can be provided, and Bayer Bitterfeld GmbH crop science company obtains formal registration for 2011 in CONTINENTAL AREA OF CHINA.
The object of the invention is to second mite azoles and spiral shell worm ethyl ester to carry out after rational mixture, acquisition can slow down and overcome the pesticide resistance of aphid, aleyrodid, evil mite, expanding prevention spectrum, the dosage that reduces, and its effect showing or activity level exceed each composition activity stack, there is unforeseeable synergistic function.
Summary of the invention
The object of the present invention is to provide a kind of mixed ratio reasonable, control efficiency is good, the synergetic pesticide composition that drug cost is low.
Another object of the present invention is to provide by this synergetic pesticide composition for preventing and treating the purposes of the aphids such as fruit, vegetables, aleyrodid, Panonychus citri, elm pawl tetranychid, Tetranychus urticae, Tetranychus cinnabarinus etc.
Technical scheme of the present invention is as described below:
A composition pesticide, the second mite azoles that it is characterized in that containing synergy effective dose and the weight ratio between spiral shell worm ethyl ester are: 1:80～80:1.
This composition pesticide, the second mite azoles that it is characterized in that containing synergy effective dose and the weight ratio between spiral shell worm ethyl ester are preferably: 1:20～20:1.
Composition pesticide of the present invention can be mixed with the preparations such as pesticide emulsion in water, oil-suspending agent, wetting powder, water dispersible granules, microemulsion according to this area conventional production process, its administration form depends on specific application; In all cases, must guarantee that they are dispersed into trickle as much as possible and even.
These preparations can be adopted preparation in a known manner, for example by by reactive compound and liquid flux/or solid carrier mix, if need, can add surfactant as emulsifier, dispersant, wetting agent, thickener and defoamer, oxidant, antifreeze, anti-photodissociation agent, fuel etc. simultaneously.If dilute with water agent, also available other organic solvent is made cosolvent.
Applicable organic solvent comprises aromatic compound (such as dimethylbenzene, benzene, toluene), chlorinated aromatic hydrocarbons compound (such as chlorobenzene), paraffin (such as petroleum distillate), alcohols (such as methyl alcohol, ethanol, ethylene glycol), ketone (such as cyclohexanone, acetone, butanone), amine (such as monoethanolamine, dimethyl formamide, ethylenediamine) etc.
The synthetic (such as high molecular silicic acid, silicate etc.) that conventional solid carrier has natural mineral matter (such as kaolin, talcum, bentonite, attapulgite, pyrophillite, potter's clay) and grinds.
Surfactant can be emulsifier, dispersant or wetting agent; Can be nonionic or ionic.For example, lauryl sodium sulfate, Teepol, neopelex, polyoxyethylene fatty acid ester, polyoxyethylene aliphatic alcohol ether, polyoxyethylene fatty amine or directly use commercial emulsifier: agriculture breast 0201B, 0203,0203B, 600# etc.Material as dispersant and wetting agent has: sodium lignin sulfonate, pull open powder, calcium lignosulfonate and sldium lauryl sulfate, alkylol polyoxyethylene groups ether sodium sulfate, octylphenol polyethylene oxyethylene group ether sulfate, alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, sodium alkyl sulfonate, neopelex etc.
Thickener; can be for example carbonyl first class alcohol, polyvinyl alcohol or polyacrylic acid or the natural water-soluble polymer synthesizing; such as xanthans, gelatin, gum Arabic, phenolic resins, shellac, Magnesiumaluminumsilicate, carboxymethyl cellulose and sodium alginate etc., adds in preparation with powder, particle or latex form.
Defoamer is: bubble enemy, silicone, C
