Description
Technical field
The present invention relates to a kind of agricultural chemicals, especially a kind of preparation of the miticide composition containing Spiromesifen and Avermectin and application.
Background technology
Spiromesifen, English common name (Spiromesifen), is mainly used in preventing and treating on cotton, vegetables and ornamental plants aleyrodid and evil mite.Its mechanism of action is the growth that affects aleyrodid and acarid, disturbs the biosynthesis of its liposome, especially larval stage is had to good activity, can also produce ovarian duct closure function simultaneously, reduces the fertility of acarid and adult whitefly, greatly reduces the quantity of laying eggs.Prove that by indoor and field trial Spiromesifen is safe to beneficial organism, and the integrated control of applicable insect, residual effect excellence, plant compatibility is good, environmentally safe.
Avermectin, English common name (Abamectin), molecular formula: C

14(B1b).Avermectin has stomach toxicity and action of contace poison to mite class and insect, can not ovicidal.What mechanism of action was different from general insecticide is to disturb neurophysiology activity, stimulate and discharge γ-aminobutyric acid, and aminobutyric acid has inhibitory action to arthropodan nerve conduction.There is paralysis symptom after contacting with Avermectin with insect larvae in mite class adult, nymph, inertia, does not take food, dead after 2～4 days.Because not causing that insect dewaters rapidly, so Avermectin lethal effect is slower.Though Avermectin has direct action of contace poison to insect predator and insect parasite, because plant surface is residual few, therefore very little to the damage of beneficial insect.Avermectin can not be moved by adsorption by soil in soil, and decomposed by microorganism, thereby in environment without cumulative function, can be used as a part of integrated control.Modulation easily, by stirring and can use a little in the preparation water of falling people, also safer to crop.
At present, Spiromesifen and Avermectin composite and being applied in both at home and abroad not yet disclosed.
Summary of the invention
The object of the invention is a kind ofly can to prevent the generation of disease drug resistance or delay pesticide resistance speed in order to propose the miticide composition containing Spiromesifen and Avermectin that use cost is low, preventive effect is good.The present invention is achieved through the following technical solutions:
The miticide composition that the present invention proposes contains A, two kinds of active components of B.
Active component A is Spiromesifen.

The amount of application when content of active component depends on independent use in the present composition, also depends on mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound, and the while is also relevant with target fungi.Conventionally in composition, the weight percentage of active component A and B is gross weight 1～90%, is preferably 2%～70%.According to different preparation types, active component content scope is different.Conventionally, containing 1～70% active component by weight in liquid preparation, is preferably 2～50%; Solid pharmaceutical preparation contains 1～85% active component by weight, is preferably 1.5～80%.
In miticide composition of the present invention, contain a kind of active ingredient, wherein at least contain a kind of surfactant, the dispersion of active component in water while being beneficial to use.Surface-active contents is 5～30% of active ingredient gross weight, and surplus is solid or liquid diluent.
The selected surfactant of miticide composition of the present invention is known in those skilled in the art, can be selected from one or more in dispersant, wetting agent, emulsifier or defoamer.According to different dosage form, in preparation, can also contain disintegrant known in those skilled in the art, antifreeze etc.
Composition of the present invention can be by user before use through dilution or directly use.Its configuration can be prepared by common processing method known in those skilled in the art, after mixing with liquid flux or solid carrier by active component, then add surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, defoamer etc.
Miticide composition of the present invention, can be processed into acceptable formulation on any agricultural chemicals on demand, and wherein more preferably formulation is wetting powder, water dispersible granules, suspending agent, aqueous emulsion, seed treatment.
Miticide composition of the present invention has protection concurrently, treats and roots out activity, can be used for preventing and treating Panonychus citri, Tetranychus cinnabarinus, grape tetranychid, apple tetranychus etc.
Composition of the present invention has following advantage:
(1) said composition shows significant synergistic effect in certain ratio range, has both improved protection effect, has reduced mu dosage and cost, has expanded again and has killed mite spectrum;
(2), because each active component in said composition does not exist the problem of cross resistance, so the application of said composition can reach and delay the drug-fast generation of pathogen and development, the result of use that contributes to extend this medicament, reduces pesticide resistance and produces probability;
(3) improved safety, mixture will be lower on the impact of environment and useful insect, safer.
