The invention belongs to the field of pesticide, and mainly discloses an ultra-low volume liquid containing tebufenpyrad, wherein the ultra-low volume liquid is used for effective preventing and controlling of crop injurious insects via ultra-low volume spraying, low volume spraying or electrostatic spraying. The ultra-low volume liquid comprises an active component, a surfactant, and a solvent; the active component is tebufenpyrad, or a mixed material prepared by mixing tebufenpyrad with an active ingredient II. The ultra-low volume liquid is characterized in that: tebufenpyrad is taken as the active compound, and the balance is the surfactant and the solvent; 100% of the ultra-low volume liquid comprises 0.5 to 20% of tebufenpyrad by mass, 1 to 10wt% of the auxiliary agent, and the balance the solvent. Preparation of the ultra-low volume liquid is convenient, cost is low, drug effect is excellent, effect lasting period is long, synergistic effect is excellent, water consumption and environmental pollution are reduced, pesticide utilization ratio is increased, and pesticide application amount is reduced.
Description
Technical field
The present invention relates to pesticide field, it is mainly a kind of ultra low volume liquids containing tebufenpyrad being realized the effective control to crop pest by ultra low volume spraying, low-gallonage spraying or ultra low volume electrostatic spray.
Background technology
The solvent that ultra low volume liquids is low by screening volatility, flash-point is high, good, low to chemical injury of crops to former medicine dissolubility, viscosity is low, be not watered during dispenser, but directly use with ultra low volume sprayer tool, low-gallonage spraying apparatus or ultra low volume electrostatic spray apparatus.Ultra low volume spraying due in droplet not containing high volatile ingredient, its size and quality arrive target process do not have significant change from leaving apparatus of spray, decrease to volatilize and elegant.Droplet is tiny and even, meets " biological best granula " requirement, significantly improves deposition.Owing to using without the need to being watered, ultra low volume liquids is suitable for water scarcity, damage by disease and insect fulminant large area occurs and the occasion of dispenser on a large scale in the palpus short time, and ultra low volume spraying simultaneously reduces the labour intensity of operator greatly.Compared with the pesticidal preparations of conventional spray application, it has following characteristic:
1. spray amount is low, 60 ~ 330 mL/ mus, be conventional spraying consumption hundreds of/mono-;
2. droplet is thin, ultra low volume liquids particle size range 20 ~ 100 μm, and conventional fogdrop diameter 200 ~ 600 μm, and the coverage rate of liquid is high, good penetrability, and drug effect is high;
3. high hundreds of times of spray liquor concentration ratio routine spraying, work efficiency height decades of times;
4. conventional spray liquor makes carrier with water, and ultra low volume makes carrier in order to high boiling point oil solvent, more resistance of rainwater washing against, and the drug effect phase is long;
5. safety is high, and ultra low volume finish is to crop safety, and its active ingredient does not adopt severe toxicity and high-toxic pesticide, is also comparatively safe to people.
At present for the control of insect agriculturally easily producing resistance, what main way was exploitation and existing kind without between the new composition of cross resistance or existing pesticide species is composite, the former is because required development cost is high, the cycle is long, and current development rate is far away less than the speed that pest resistance to insecticide produces.Therefore, the selection that mixture is a kind of the best is carried out for the existing pesticide species that the mechanism of action is different.If reasonable mixture ratio, then can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose.Certain defect is usually there is in the insecticide containing single-activity composition on agricultural insect pests control, continuous several times uses and not only makes insect easily develop immunity to drugs, and easily cause the pollution to food and environment, above shortcoming can be overcome by rational mixture between pesticide active ingredient.The reasonably composite synergistic effect that active ingredient is produced simultaneously, preventive effect can be improved, reduce effective ingredient consumption, cost-saving, delay the drug-fast generation of insect, near and the pollution even avoiding agricultural chemicals to food and environment can be alleviated, and the efficient novel pesticide of the low toxicity that the present invention researchs and develops, not only target drug effect is significantly strengthened, and very low on the impact of people, crop, non-target and environment.
The English name of tebufenpyrad is Tebufenpyrad, and chemical name is N-(4-tertiary butyl benzyl) the chloro-3-ethyl of-4--1-methylpyrazole-5-base formamide, its chemical structural formula is
Tebufenpyrad belongs to amide-type miticide. to various mite class and Semiptera, homoptera pest, there is tall and erect effect, and the dawn all to have immediate effect to mite class each vegetative period and efficiently, the lasting period is long. as Tetranychidae (panonychus ulmi, citrus red mite, cotton spider mites, Tetranychus cinnabarinus etc.), Tarsonemidae (the many tarsonemids in side), Eriophyidae (thorn apple rust mite, grape rust mite etc.), Tenuipalpidae (grape brevipalpus), Aphidiadae (black peach aphid, cotten aphid, apple aphid), Aleyrodidae (cassava aleyrodid). with dicofol, fenbutatin oxide, thiazole mite ketone etc. without cross resistance.True in interior absorption, but have osmotically active, have splendid selectivity to target crop, under recommended dose (25 ~ 200mg (a.i.)/L) to most of crop without poisoning.
Spiral shell worm ethyl ester is the tetronic acid class novel pesticide of Beyer Co., Ltd's exploitation.English by name spirotetramat, chemistry 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2,5-xylyl)-1-azaspiro [4, the 5] by name-last of the ten Heavenly stems-3-alkene-2-ketone, chemical structural formula is:
The mechanism of action of spiral shell worm ethyl ester is interference insect Fatty synthesis, blocks energy metabolism, be the management of anabasine insecticide resistance select kind.Spiral shell worm ethyl ester has unique interior absorption: be the insecticide uniquely so far with interior suction Bidirectional Conduction performance, upwards can move down, arrive at blade face and bark in whole plant corpus, thus control crop is inner and the corticole insect of fruit.The interior absorption of this uniqueness can protect newborn stem, leaf and root, prevents ovum and the larval growth of insect; Lasting period is long: can provide the effective control reaching 8 weeks; Drug effect is high: active component consumption is 52-105 g ai/ha; Pest control spectrum is wide: can effectively prevent and treat various sucking pest, as aphid, thrips, wood louse, mealybug, aleyrodid and scale insect etc.Applicable chief crop comprises cotton, soybean, oranges and tangerines, tropical fruit tree, nut, grape, lupulus, potato and vegetables etc.; To natural enemies security: to important beneficial insect as ladybug, syrphus fly and parasitic wasp have good selectivity.
