Description
Technical field
The present invention relates to composition pesticide and its application field, specifically using sulfur-phosphor and flufenzine to be effective living
Property composition compounding binary complex, be mainly used in the preventing and treating of insect on crops.
Background technology
Sulfur-phosphor：A kind of absorbability organic phosphates insecticidal/acaricidal agent, have it is stronger tag and stomach poison function, effect
Mechanism is the inhibitor of acetylcholinesterase.To citrus red mite, arrowhead scales, cotton boll worm, vegetables oriental tobacco budworm, diamondback moth and
The insects such as planthopper have good prevention effect.
Flufenzine：It is a kind of tetrazine class acaricide, there is stronger action of contace poison, it is strong to knock down power, into mite, deutonymph, children
Mite and ovum are effective.There is fine preventive effect to evil mites such as panonychus citri, blister mite, yellow tea mite, Tetranychus cinnabarinus and Tetranychus urticaes.
In addition, flufenzine has to insects such as pear sucker, oystershell scale and leafhopper classes simultaneous controls effect well.
The resistance problem of agricultural pests is a global problem, is always the emphasis class of agricultural science and technology worker concern
Topic.With using pesticide control pest continuity year in year out, the increase of Pesticide use amount and not scientifical use agricultural chemicals etc.
Factor, cause pest resistance getting worse, the pest species for producing resistance are on the increase.Meanwhile the use agricultural chemicals of high intensity, lead
Exceeded Practice for Pesticide Residue in Agricultural Products, pollution environment are caused and a series of problems, such as peasant's drug cost increase, be unfavorable for agricultural can
Sustainable development.
The present inventor is during further investigation sulfur-phosphor and flufenzine compounded formula, surprisingly nitre worm
Sulphur phosphorus and flufenzine are compounded, to the various pests on crops in the range of certain compound proportion, especially to citrus
Scale insect, wood louse on tree, red spider have significant synergistic function, after further study, complete the present invention.
The content of the invention
It is an object of the invention to provide a kind of component is reasonable, obvious synergy, insecticidal effect are outstanding, the lasting period
Length, drug cost is low, insect can be delayed to develop immunity to drugs, and to the composition pesticide of Crop securify.
Another object of the present invention is to provide a kind of composition pesticide preparation formulation containing sulfur-phosphor and flufenzine.
It is still another object of the present invention to provide scale insect of the above-mentioned composition pesticide on preventing and treating mandarin tree, wood louse, red
The purposes of the insects such as spider.
Technical scheme：To achieve the above object, the present invention provides a kind of agriculture containing sulfur-phosphor and flufenzine
Drug composition, effective active composition are made up of sulfur-phosphor and flufenzine, and the weight ratio of sulfur-phosphor and flufenzine is 20:1~
1:1, the preferably weight ratio of sulfur-phosphor and flufenzine is 15:1~1:1.
Further, in certain embodiments, the weight of sulfur-phosphor and flufenzine ratio is 7:1.
Further, in certain embodiments, the weight of sulfur-phosphor and flufenzine ratio is 5:1.
Further, in certain embodiments, the weight of sulfur-phosphor and flufenzine ratio is 3:1.
In composition pesticide of the present invention, the gross weight percentage composition of sulfur-phosphor and flufenzine is 1%~85%, preferably nitre
Worm sulphur phosphorus and the gross weight percentage composition of flufenzine are 5%~70%.
Composition pesticide of the present invention can be prepared into any formulation used in suitable agricultural production, and relatively good formulation has
Aqueous emulsion, missible oil, suspending agent etc..
In various application forms prepared by composition pesticide of the present invention, in addition to effective active composition, in addition in agricultural chemicals
Allow to use and the various auxiliary elements of acceptable.
Described auxiliary element includes but is not limited to solvent, emulsifying agent, wetting agent, dispersant, antifreezing agent, thickener, disappeared
Infusion, synergist and preservative etc., be all in pesticidal preparations commonly use or allow the composition used, be not particularly limited, specifically into
Divide and dosage passes through experiment according to recipe requirements and determined.
The production technology of the various application forms of composition pesticide belongs to existing known technology, will not be repeated here.
Compared with prior art, the advantage of the invention is that：
1st, sulfur-phosphor and flufenzine compounding have significant synergistic function, are used alone and significantly improve than single dose
To the prevention effect of insect on crops.
2nd, sulfur-phosphor and flufenzine two kinds of active components compounding, reduce Pesticide use amount, reduce use cost, subtract
The light pollution to environment.
3rd, sulfur-phosphor and flufenzine two kinds of active components compounding, the mechanism of action is different, action site increase, delays
The generation of pest resistance to insecticide, add the service life of agricultural chemicals.
