Effective components are a first active ingredient cyenopyrafen and a second active ingredient fenpyroximate, wherein the weight ratio of the first active ingredient to the second active ingredient is (40-1):(1-40), and the sum of contents of the first active ingredient and the second active ingredient is 2-40% of the total weight of the pesticide composition. The pesticide composition disclosed by the invention can be prepared into agriculturally allowable emulsion in water, a suspending agent, water dispersible granules and a microcapsule suspending agent. The pesticide composition containing cyenopyrafen is reasonable in composition and has a good effect on panonychus ulmi, hawthorn spider mites, two-spotted spider mites, tetrangychus cinnabarinus and yellow tea mites; meanwhile, the pesticide cost is low, the durable effect is long, the residual quantity of a preparation is low, no pollution is produced to crops, the safety is good, production of resistance can be effectively delayed compared with existing single dosage, and the safety requirements of a pesticide preparation can be met.
Description
Technical field
The present invention relates to a kind of composition pesticide and uses thereof, by the first active component nitrile pyrrole mite ester, the second active component fenpyroximate and other auxiliary agent compositions be applicable to, for preventing and treating Agricultural Mites, belong to technical field of compounded pesticide.
Background technology
Nitrile pyrrole mite ester, English general cyenopyrafen by name.It is a kind of novel pyrazoles miticide.Produce OH-form by metabolism and produce activity.This OH-form reaches the mitochondrial usefulness of suppression by upsetting complexⅱ (succinate dehydrogenase) on respiratory electron transport chain.After tert-butyl ester hydrolysis, higher inhibitory action is shown to mitochondrial protein complexⅱ, hinder electron transmission, destroy oxidative phosphorylation process.It belongs to contact killing type miticide, with existing miticide without cross resistance.But nitrile pyrrole mite ester action site is single, if action spectrum relative narrower, long-term single use, inevitably produces resistance.Producing by carrying out the composite pesticide resistance that not only can delay with other effective insecticidal/acaricidal agents, can also action spectrum be widened, mite can be prevented and treated into and can prevent and treat young mite and ovum again.
Fenpyroximate, English general fenpyroximate by name.It is a kind of oximes miticide.Mainly through suppressing mitochondrial membrane electro transfer thus affect the normal operation of respiratory chain, cause the death of mite class.This medicament has strong tagging and stomach poison function to multiple harmful mite, and quick-acting is good, and the lasting period is long, all have good control efficiency, and it is inhibited to cast off a skin to pupa to each breeding time of evil mite.This product not only kills mite spectrum extensively, and has the desinsection effect of curing the disease concurrently, also has good preventive and therapeutic effect to the insects such as diamond-back moth, prodenia litura, black peach aphid and the disease such as powdery mildew, downy mildew.
Evil mite belongs to arachnids Acarina, be commonly called as two spotted spider mite, be endanger one of heavier insect in agricultural production, the various vegetables such as the multiple fruit tree such as main harm apple, hawthorn, jujube tree, oranges and tangerines and Solanaceae, Curcurbitaceae, pulse family, Liliaceae, can also endanger the economic crops such as cotton.It mainly lives in the leaf back side, if inhale fruit, blade and tender tip juice to become mite to sting.Blade be injured after chlorophyll be damaged, affect the photosynthesis of plant, blade presents sallow point or patch, and final leaf abscission often causes crushing disaster; Fruit becomes pitchy after being injured, and is commonly called as " casting skin fruit ", and is abound with the netted microgroove of be full of cracks, have a strong impact on the quality of fruit.The ground such as Hebei, Beijing, Henan, the east area of the Liao River, coextensive with eastern and southern Liaoning Province, Jiangsu, Guangdong, Guangxi are mainly distributed in China.The medicament that current control does harm to mite main comprises Avermectin, pyridaben, flolimat, propargite etc., but mite class fertility is very strong, the fastest 5 days generation, and the single medicament of Long-Time Service easily produces resistance.
The insect of resistance is agriculturally produced for control, a kind of way be release new for the new component of existing kind without cross resistance.But new active ingredient development cost is high, and the cycle is long, usually costly, and once there is resistance, usually causes chemical control to lose efficacy, be forced to stop using or eliminate.Other method, as crop structure adjustment, different agricultural chemicals rotations etc., in the process of practical operation, is difficult to really play obvious effect.Different cultivars composition carries out composite, is to prevent and treat resistant insect or do harm to the very common way of mite.The compounded formula screening of the present inventor to nitrile pyrrole mite ester and fenpyroximate conducts in-depth research, find that nitrile pyrrole mite ester and fenpyroximate carry out composite, within the scope of certain compound proportion, there is obvious synergistic effect, in actual use, there is good preventive effect to mite pest agriculturally simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of miticidal effect good, drug cost is low, the composition pesticide containing nitrile pyrrole mite ester not easily developed immunity to drugs.
Another object of the present invention is to provide the purposes of above-mentioned composition in control mite class.
In order to overcome the defect of existing single component formulations, realize above-mentioned purpose, technical scheme of the present invention solves like this:
A kind of composition pesticide containing nitrile pyrrole mite ester and the purposes on control evil mite thereof, it is characterized in that: active ingredient is made up of the first active component nitrile pyrrole mite ester, the second active component fenpyroximate, wherein, calculate according to weight ratio, the ratio of the first active component and the second active component is 40:1-1:40, and content sum is the 2%-40% of described composition total weight.
The composition pesticide that the present invention contains nitrile pyrrole mite ester is aqueous emulsion, suspending agent, water dispersible granules, microcapsule suspending agent according to the preparation formulation that the method that those skilled in the art of the present technique are known can be prepared.
The present invention contains the composition pesticide of nitrile pyrrole mite ester and is preventing and treating the purposes of the composition pesticide mainly containing nitrile pyrrole mite ester in the purposes on evil mite on control panonychus ulmi, hawthron spider mite, Tetranychus urticae, Tetranychus cinnabarinus, yellow tea mite.
Instant component is reasonable, good disinsection effect, and drug cost is low, and active component nitrile pyrrole mite ester and fenpyroximate have significant synergies, quick-acting is high, lasting effect is long, slows down the generation of resistance, preparation less residue, pollution-free to crop, safety is good, meets the security requirement of pesticidal preparations.
Embodiment
Essence for a better understanding of the present invention, is described further content of the present invention below in conjunction with embodiment.
In order to prevent and treat panonychus ulmi (
