Abstract
The invention relates to a synergistic pesticide composition. The active ingredients of the composition are cyflumetofen and an organophosphorus insecticide, wherein the weight ratio of the cyflumetofen to the organophosphorus insecticide is 20:1-1:50, and the two active ingredients are prepared into various forms including missible oil, microemulsions, EW (emulsions in water), suspending agents, microcapsule suspending agents and suspoemulsions. The composition is used for preventing and controlling pest mites of crops, and especially can be used for preventing and controlling panonychus citri mcgregor and tetranychus urticae koch; and the composition has a synergistic effect, is quick-acting and long-acting, and can reduce consumption of pesticide, save manpower, and contribute to delaying the development of insect resistance.
Description
Technical field
The present invention relates to a kind of composition pesticide, be specifically related to a kind of fourth fluorine mite ester and organic phosphorous insecticide composition pesticide of containing, be used for preventing and treating insect and evil mite on the agricultural.
Background technology
Organic phosphates is the important insecticide of a class, and organophosphorous pesticide still holds pride of place in China's agricultural chemicals usage amount at present.Progressively substitute or the some of the pesticide species structural adjustment that partly to substitute high malicious organophosphorous pesticide be China.The harmful mite generation on the agricultural crops is many, and breeding is fast, easily produces resistance, the good miticide kind of some original preventive effects, and as Avermectin, pyridaben etc., through using for a long time for many years, the time that miticidal effect obviously descends or a dispenser is effectively controlled is very short.By the access times of lasting increase agricultural chemicals and the working concentration of raising agricultural chemicals, still can't reach desirable control efficiency, also increased the murder by poisoning of human and environment has been polluted.
Fourth fluorine mite ester: English common name Cyflumetofen; it is the novel acyl group acetonitrile class miticide by the exploitation of Japan big tomb chemical company; this medicament is remarkable to mite class effect, wherein to the one-tenth mite of tetranychid, if mite, ovum all have special efficacy, can be used for various melons and fruits, flowers and vegetables.
At present, the fourth fluorine mite ester number lattice height of selling on the market, and mostly be unitary agent, in fact, there is the risk that easily produces resistance in this unitary agent in the control mite pest.
Summary of the invention
1. goal of the invention
The object of the present invention is to provide a kind of composition pesticide, be characterized in higher to the plant insect activity, obvious synergistic effect is arranged, can obviously reduce the usage amount of organophosphorous pesticide, and itself be difficult for producing resistance.
Another object of the present invention provides the application of this composition pesticide on agricultural.
2. technical scheme
The agricultural chemicals of different mechanism of action shows three kinds of type of action: summation action, synergistic effect and antagonism after mixing usually.But be specially which kind of effect, can't do not determine by a large amount of tests.The inventor is by the large number of biological screening test, is surprised to find that uses that be mixed by a certain percentage of part organophosphorus insecticide that fourth fluorine mite ester and the present invention select, has synergistic effect to doing harm to mite, after further study, finished the present invention.
Composition pesticide provided by the present invention, be that active ingredient is carried out composite with fourth fluorine mite ester and organophosphorus insecticide, the organophosphorus insecticides that relates to is a kind of among chlopyrifos (chlorpyrifos), Hostathion (triazophos), Profenofos (profenophos), quinalphos (quinalphos) and malathion (malathion), though they there are differences at structure, activity level, the evil mite there are the essentially identical mechanism of action and similar effect characteristics.
In the composition pesticide of the present invention, active ingredient fourth fluorine mite ester and organic phosphorous insecticide mass ratio are 20 :-1: 50, and preferred proportion is 1: 1-1: 20.
Composition pesticide of the present invention is mixed with any one formulation that those skilled in the art are familiar with in actual applications, and preferred formulation is missible oil, microemulsion, aqueous emulsion, micro-capsule suspension, suspension emulsion.Active ingredient total content in the preparation is 5%～60%.
Auxiliary material in the present composition preparation comprises that emulsifier, solvent, stabilizing agent, antifreezing agent, dispersant, carrier and other are of value to the known substance of active ingredient stable and drug effect performance in preparation, all be composition commonly used in the pesticidal preparations field, do not have restriction especially.
Composition pesticide of the present invention is used for insect or the evil mite of taking place on the control crops, especially can effectively prevent and treat the Tetranychus urticae of the crops such as Panonychus citri, apple of crop such as citrus.
3. beneficial effect
Fourth fluorine mite ester and the organic phosphorous insecticide composition pesticide of containing provided by the invention can produce following beneficial effect:
(1) this composition pesticide has synergistic function to the evil mite, can improve control efficiency, reduces the agricultural chemicals usage amount, thereby has reduced harmful effect and residue of pesticide to environment.
(2) this composition pesticide has enlarged the control spectrum, and a dispenser is pest control and evil mite simultaneously.
(3) mechanism of action difference of two kinds of active ingredients of this composition pesticide has the notable synergistic effect, and the use that is mixed can delay evil mite pesticide resistance and produce and development.
Embodiment
The invention will be further described below in conjunction with embodiment, is not for restriction the present invention.
Among the embodiment in the proportioning of all preparations percentage be mass percent.The treatment dosage of biologicall test part and the test of pesticide effectiveness is effective ingredient consumption.
