Description

A kind of containing ring bromine insect amide and the Pesticidal combination of paichongding
Technical field
The present invention relates to agricultural insecticide compositions and application thereof, specifically one contain Ring bromine insect amide and the Pesticidal combination of paichongding.
Background technology
Ring bromine insect amide, bisamide insecticides, there is the insecticidal activity of wide spectrum, to diamondback moth, Prodenia litura, aleyrodid, aphid, thrips, housefly, liriomyza bryoniae, Coptotermes formosanus Shtrari. etc. have well to be killed Effect, can use crop and include the multiple field crops such as Citrus, Cotton Gossypii, Caulis et Folium Brassicae capitatae, vegetable and fruit Tree etc., and there is good systemic activity, can be as sanitary insect pests such as bait formulation preventing and treating houseflies；To the greatest extent Structurally it possesses the biamide structure of ryanodine receptor inhibitor to pipe, it is reported that its tool There is different mechanism of action.
Paichongding, anabasine insecticide, there are good Uptake and translocation function, medicament after dispenser Can quickly be transmitted to each position of plant, various sucking pests are had preferable prevention effect.
The resistance problems of agricultural pests is a global problem, always agricultural science and technology work The emphasis problem that author pays close attention to.Continuity year in year out, pesticide along with Chemical Control of Harmful Insects The factors such as the increase of usage amount and not scientifical use pesticide, cause pest resistance day by day serious, The pest species producing resistance is on the increase.Meanwhile, the use pesticide of high intensity, result in agriculture Product pesticide residues exceed standard, pollute the series of problems such as environment and peasant's drug cost increase, no It is beneficial to the sustainable development of agricultural.
The present inventor, during further investigation ring bromine insect amide and paichongding compounded formula, makes People is surprised to find that ring bromine insect amide and paichongding compound, in certain compound proportion scope Interior to the various pests on crops, especially to lepidoptera pest, homoptera pest, half wing Mesh insect and Thysanoptera have significant synergistic function, after further study, complete The present invention.
Summary of the invention
It is desirable to provide a kind of containing ring bromine insect amide and the Pesticidal combination of paichongding, should Pesticidal combination has significant synergistic function, to the various pests on crops, especially Be lepidoptera pest (as striped rice borer, yellow rice borer, rice leaf roller, diamondback moth, Pieris rapae, Prodenia litura, beet armyworm, bean-pod borer, leaf roller, bollworm etc.), homoptera pest (as Scale insect, trialeurodes vaporariorum, pear sucker, Bemisia tabaci, planthopper, aphid, tea lesser leafhopper etc.), Hemipteran pest (such as fleahopper silk worm etc.) and Thysanoptera (such as thrips etc.) have the anti-of excellence Control effect.
Technical scheme: a kind of containing ring bromine insect amide and the Insecticidal combinations of paichongding Thing, including effective ingredient ring bromine insect amide and paichongding, ring bromine insect amide and the weight of paichongding Ratio is 20:1～1:15, ring bromine insect amide and paichongding weight summation weight in the composition Percentage ratio is 1%～85%, and remaining is agriculturally to accept and to allow the pesticidal preparations used auxiliary Co-ingredients.
Further, the preferred weight ratio of ring bromine insect amide and paichongding is 10:1～1:8.
In Pesticidal combination of the present invention, in addition to effective ingredient, also include solvent, cosolvent, breast Agent, dispersant, wetting agent, thickening agent, antifreezing agent, cyst material, pH adjusting agent, Defoamer, disintegrating agent, stabilizer, penetrating agent, diffusant, preservative, synergist, poisoning The pesticide such as palliative, binding agent, density adjuster and filler allow use and acceptable Auxiliary element is all conventional in pesticidal preparations or allows the composition used, and is not particularly limited, Concrete composition and consumption are determined by test according to recipe requirements.
Pesticidal combination of the present invention can be prepared as the multiple application being suitable in agricultural production using Dosage form, reasonable dosage form has microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, moisture Shot agent, wettable powder and ultra low volume liquids.
The production technology of the various application forms of described Pesticidal combination all belongs to existing known technology, Do not repeat them here.
Product described in the invention can provide with the form of finished product preparation, i.e. each thing in compositions Matter is the most blended.The composition of compositions can also the form of single dose provide, directly at tank before using Or bucket mixes, it is then diluted to required concentration.
The frequency of administration of Pesticidal combination of the present invention and amount of application are with crops, insect, weather feelings Condition changes and has small variations, can reach, by using suitable dosage, the mesh effectively prevented and treated 's.
Compared with prior art, it is an advantage of the current invention that:
1, ring bromine insect amide and paichongding compound and have significant synergistic function, than list Agent is used alone and significantly improves the prevention effect of insect on crops.
2, ring bromine insect amide and two kinds of active component of paichongding compound, and decrease Pesticide use amount, Reduce use cost, alleviate the pollution to environment.
3, ring bromine insect amide and two kinds of active component of paichongding compound, and the mechanism of action is different, Action site increases, and has delayed the generation of pest resistance to insecticide, has added the service life of pesticide.
