Description
Technical field
The present invention relates to pesticide field, it is mainly a kind of by ultra low volume spraying, low-gallonage spraying or the ultra low volume liquids containing tebufenpyrad of ultra low volume electrostatic spray realization to effective control of crop pest.
background technology
The solvent that ultra low volume liquids is low by screening volatility, flash-point is high, good to former medicine dissolubility, low to chemical injury of crops, viscosity is low, during dispenser, be not watered, but directly use with ultra low volume sprayer tool, low-gallonage spraying apparatus or ultra low volume electrostatic spray apparatus.Ultra low volume spraying is owing to not containing high volatile volatile composition in droplet, and its size does not have significant change with quality from leave spraying apparatus arrival target process, has reduced and has volatilized with elegant.Droplet is tiny and even, meets " biological best granula " requirement, has significantly improved deposition.Owing to using without 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 operator's labour intensity greatly.Compare 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 μ m, and conventional fogdrop diameter 200～600 μ m, and the coverage rate of liquid is high, good penetrability, drug effect is high;
3. the conventional spraying of spray liquor concentration ratio is high hundreds of times, the high decades of times of work efficiency;
4. conventional spray liquor is made carrier with water, and ultra low volume is made carrier in order to high boiling point oil solvent, resistance of rainwater washing against more, and the drug effect phase is long;
5. safe, ultra low volume finish is to crop safety, and its active ingredient does not adopt severe toxicity and high-toxic pesticide, to people, is also comparatively safe.
At present for easily producing the control of insect of resistance in agricultural, 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 the speed that development rate produces less than pest resistance to insecticide far away at present.Therefore, for the different existing pesticide species of the mechanism of action, being mixed is a kind of selection of the best.If reasonable mixture ratio, can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose.On agricultural insect pests control, usually there is certain defect in the insecticide that contains single-activity composition, continuous several times is used and is not only made insect easily develop immunity to drugs, and easily cause the pollution to food and environment, by rational mixture between pesticide active ingredient, can overcome above shortcoming.The reasonably composite synergistic effect that active ingredient is produced simultaneously, can improve preventive effect, reduce effective ingredient consumption, cost-saving, delay the drug-fast generation of insect, closely can alleviate and even avoid the pollution of agricultural chemicals to food and environment, 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.
