Abstract
The invention belongs to the field of plant protection and relates to a pesticide composition containing sulfoxaflor and pyridaben. The mass part ratio of sulfoxaflor to pyridaben in the composition is equal to (0.1-10) to 1; and the sulfoxaflor and the pyridaben are processed to be prepared into a suspending agent, water dispersible granules, wettable powder, granules and other dosage forms which are used for preventing and controlling diseases and insect pests of vegetables, corn, cotton, rice, fruit trees and wheat crops and particularly preventing and controlling insect pests such as thrips, aleyrodid, aphid, red spider, rice planthopper and leafhopper which all belong to homoptera and physopoda.
Description
Technical field
The invention belongs to plant protection field, relate to a kind of composition that contains fluorine pyridine worm amine nitrile and pyridaben.The present invention can be effective to prevent and treat the insects such as thrips, aleyrodid, aphid, two spotted spider mite, rice fulgorid.
Background technology
The insects such as thrips, aleyrodid, aphid, two spotted spider mite, rice fulgorid, leafhopper are the important pests on the crops such as paddy rice, vegetables, fruit tree or cotton, and these insect breeding amounts are large, and generation overlap is obvious.And the damage by disease and insect of same crop often occurs simultaneously, peasant often attends to one thing and lose sight of another when pest control separately or disease, not only delay work and miss control opportunity, from and strengthen dosage etc.In recent years, due to single and Scientific Usage of Drugs not, cause the destruction of the raising of peasant's cost, environmental pollution and ecotope etc.The composition of two kinds of different structures, the different mechanisms of action being carried out composite, is to reduce and the effective way of delaying drug resistance insect, expanding prevention target, raising drug effect.
Fluorine pyridine worm amine nitrile acts on the nervous system of insect, acts on binding site unique in nicotinoids acetylcholinergic receptor and brings into play insecticidal function.Can be through leaf, stem, root absorption and enter in plant corpus.Fluorine pyridine worm amine nitrile is applicable to prevent and treat all suckings pest such as cotton aleyrodid, fleahopper, aphid, plant hopper and coccid, efficiently, fast and the lasting period long, can effectively prevent and treat nicotinoids, chrysanthemum ester class, organophosphate and carbamate pesticide produces the sucking pest of resistance, by resistance to insecticides Action Committee, is regarded as unique brand-new active ingredient of Group4C class.Low to non-target arthropods toxicity, be integrated pest control preferred agents.
Pyridaben is wide spectrum, tagging property miticide, if to being the whole vegetative period of mite ovum, young mite mite and becoming mite to have good effect.This medicine is not acted upon by temperature changes, and no matter uses in early spring or autumn, all can reach promising result.
Inventor has carried out the test of pesticide effectiveness of the composition of a large amount of fluorine pyridine worm amine nitriles and pyridaben, has found many beyond thought effects.This invention improves drug effect and expanding prevention target, is beneficial to and reduces medication number of times, reduces agriculture originally and improve agricultural product economic benefit.
Summary of the invention
The object of this invention is to provide a kind of composition and application thereof that contains fluorine pyridine worm amine nitrile and pyridaben of a kind of energy delaying drug resistance insect, expanding prevention target, raising control efficiency.
The composition pesticide that contains fluorine pyridine worm amine nitrile and pyridaben, in composition, the ratio of quality and the number of copies of fluorine pyridine worm amine nitrile and pyridaben is 0.1-10:1, preferred, ratio of quality and the number of copies is 0.4-4:1.
Above-mentioned composition can be processed and be mixed with suspending agent, water dispersible granules, wetting powder, granule, microemulsion or aqueous emulsion etc., and processing method is the formulation preparation method of this area routine.
Composition of the present invention is for preventing and treating the insect pest of the crops such as vegetables, corn, fruit tree, cotton, paddy rice, wheat.
Controlling object of the present invention is the insects such as Homoptera, thrips, coleoptera, Lepidoptera.Preferably, insect is one or more in thrips, aleyrodid, aphid, two spotted spider mite, rice fulgorid, leafhopper etc.
Composition pesticide of the present invention compared with prior art, produces following beneficial effect:
(1) composition is obvious to synergistic effects such as insect thrips, aleyrodid, aphid, two spotted spider mite, leafhopper, rice fulgorids;
(2) composition has expanded control target, and a dispenser can prevent and treat multiple insect pest simultaneously, and has reduced agricultural cost;
(3) because the mechanism of action of composition active component is different, according to pest resistance to insecticide theory and practice, the application of composition can delay the resistance development of insect to fluorine pyridine worm amine nitrile, extends its service life.
