Abstract
The invention relates to an insect and mite killing composition containing Cyflumetofen and emamectin benzoate. The insect and mite killing composition is prepared by binary formulation of Cyflumetofen and emamectin benzoate which serve as active ingredients. The weight ratio of Cyflumetofen to emamectin benzoate is 1:5-40:1. The insect and mite killing composition also comprises auxiliary ingredients which are allowed and acceptable in pesticides. The insect and mite killing composition can be used for preventing and controlling insects and mites like polyphagotarsonemus latus, Panonychus citri Me Gregor, Tetranychus urticae, tetranychus cinnabarinus, tea lesser leafhopper, tea leaf roller, cavity small leaf moth, worms in appetite and so on. The insect and mite killing composition has an obviously improved effect and a continuous preventing and controlling effect, and is safe to human beings and livestock and has high environmental compatibility, and the dosage of pesticides is reduced.
Description
Technical field
The invention belongs to agriculture chemical compounding technical field, relate to a kind of composition pesticide, specifically a kind of insecticide acaricide composition containing cyflumetofen and Affirm (Merck Co.).
Background technology
Mite pest, claims two spotted spider mite, is one of primary pest of the crops such as fruit tree, cotton, tealeaves, has a strong impact on the growing way of fruit tree and crops.Because the generation of mite class is many, breeding spreads fast, and many generations alternately grow up, thereby the control quite difficulty of getting up, and mite class and general farmland disaster physiological mechanism is different, general insecticide does not almost have preventive and therapeutic effect to mite class.Past, China is less for preventing and treating the specialized acaricide of mite class, generally uses dicofol, pyridaben, propargite, isocarbophos, azacyclotin and their mixture, and control efficiency is not good, every year all need to use a large amount of agricultural chemicals and carry out control of insect, to retrieve crop yield loss as far as possible.But indiscriminate use of pesticide, is used insect to produce more and more serious resistance to agricultural chemicals, causes control efficiency reduced year by year.Therefore, be badly in need of the Pesticidal products of more efficient, safety, environmental protection.
By the composite agricultural chemicals of making of different agriculture the effective elements of the medicines, it is a kind of effectively and efficiently mode of the upper resistance germ of current development novel pesticide and control agricultural.The agricultural chemicals of different cultivars shows three kinds of type of action: summation action, synergistic effect and antagonism after mixing conventionally.But be specially which kind of effect, unpredictable, only have by lot of experiments and just can know.Compound synergic is well filled a prescription, and can obviously improve actual control efficiency, reduces the usage amount of agricultural chemicals, can also expand fungicidal spectrum, and improve germicidal efficiency, thereby delay widely the drug-fast generation speed of germ, be the important means of integrated control disease.The present invention, by a large amount of desk research and field experiment, has filtered out the complex composition of cyflumetofen and Affirm (Merck Co.), and cyflumetofen is different from the mechanism of action of Affirm (Merck Co.), and mutually composite have good synergistic effect within the specific limits.And take composite that dithianon and Affirm (Merck Co.) be active ingredient, there is not yet at present relevant report at home and abroad.
Cyflumetofen (Cyflumetofen), trade name Danisraba, the novel acyl group acetonitrile class miticide of Shi You great tomb chemical company exploitation, with existing insecticide without cross resistance.Within 2007, get permission to register and sell first in Japan, for crops and flowers such as fruit tree, vegetables, dish trees, control parasitizes the main mite class of plant.To the ovum of tetranychid with to become mite all effective, if higher to the activity of mite.
Affirm (Merck Co.), is the abbreviation of emamection benaoate, is a kind of new and effective semisynthetic antibiotics insecticide.The feature with super-high-efficient, low toxicity, low-residual, the biopesticide such as nuisanceless, activity to the larva of lepidopterous insects and other many insects is high, existing stomach poison function is double action of contace poison again, under low-down dosage, there is good effect, and in the process of pest control, beneficial insect is not injured, be conducive to the integrated control to insect, expanded in addition insecticidal spectrum, reduced the toxicity to people and animals.
Summary of the invention
The object of the invention is for practical problems such as current miticide dosage are large, cost is higher, reuse easy generation resistance, insecticidal spectrum is narrow, a kind of insecticide acaricide composition containing cyflumetofen and Affirm (Merck Co.) is provided, it can fully improve insecticidal effect, expand insecticidal spectrum, reduce dosage, reduce costs.
Technical scheme of the present invention is as follows:
A kind of insecticide acaricide composition containing cyflumetofen and Affirm (Merck Co.), this insecticide acaricide composition be take two yuan that cyflumetofen and Affirm (Merck Co.) carry out as active ingredient composite, the weight ratio of described cyflumetofen and Affirm (Merck Co.) is 1:5～40:1.
