Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of insecticidal and bactericidal composition for water prevention chilo suppressalis, rice leaf roller, banded sclerotial blight and rice blast.
Background technology
Epoxiconazole (Epoxiconazole): belong to triazole bactericidal agent, the mechanism of action is C-14 demethylation enzyme inhibitor in sterol biosynthesis, has protection and therapeutic action concurrently.The control of the disease such as leaf spot, powdery mildew, rust, banded sclerotial blight on the crops such as suitable wheat, barley, paddy rice, beet, rape, legume, vegetables, grape and apple.Under recommended dose to crop safety, without poisoning.
Fenoxanil (Fenoxanil): belong to benzene oxanamide series bactericidal agent, its mechanism of action is melanin biosynthesis inhibitor, mainly suppresses the activity of pillar spore ketone dehydrogenase, thus suppresses the melanic formation of Pyricularia oryzae.Have good interior absorption, also have good effect after dispenser to the new blade launched, dispenser still can suppress coming off and dispersing of spore on scab for 40 days, thus avoids superinfection.
Ryanodine receptor inhibitor insecticides has the brand-new mechanism of action, activates ryanodine receptor, makes the improper long-time opening of receptor channel, cause calcium ion unrestrictedly to discharge, make the exhaustion of calcium storehouse, muscular paralysis, finally causes insect dead.At present, the principal item that ryanodine receptor inhibitor insecticides is successfully developed has chlorine fluorine cyanogen insect amide, fluorobenzene insect amide, Rynaxypyr, bromine cyanogen insect amide etc., these kinds all to the lepidoptera pest on crops, as striped rice borer, paddy stem borer rice leaf roller etc. have extraordinary control efficiency.
For the extermination of disease and insect pest agriculturally easily developed immunity to drugs, the use mechanism of action is different, the different pesticide species of control spectrum carries out the selection that mixture is a kind of the best.If reasonable mixture ratio, then can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose, expanding prevention is composed.Disease and the insect pest of large Tanaka often mix generation, as the striped rice borer on paddy rice mixes generation with damage by disease and insect such as banded sclerotial blights throughout the year, peasant needs to buy insecticide and bactericide simultaneously, the edge of a field mixes temporarily, random large, is not often Use out of range, cause waste, increase environmental pollution, use quantity not sufficient exactly, impact prevents and treats quality.And part bactericide and insecticide are due to reasons such as chemical reactions, and are not suitable for mixture and use together, mixture is improper also easily causes degradation problem under control efficiency.
Summary of the invention
The object of the invention is for above-mentioned Problems existing, a kind of insecticidal and bactericidal composition is provided, for preventing and treating striped rice borer on paddy rice, rice leaf roller, the multiple damage by disease and insect such as banded sclerotial blight and rice blast, a drug can parasitosis be double controls, simplify farming, joint medicine cost, reduces environmental pollution, improves and prevent and treat quality.
Technical scheme of the present invention: a kind of composition of pesticide-germicide, be made up of effective constituents A, B, C and conventional auxiliary element, effective constituents A percentage by weight is in the composition 0.1% ~ 60%, active ingredient B percentage by weight is in the composition 0.1% ~ 60%, active ingredient C percentage by weight is in the composition 1% ~ 60%, effective constituents A is selected from epoxiconazole, active ingredient B is selected from fenoxanil, and active ingredient C is selected from the one in chlorine fluorine cyanogen insect amide, fluorobenzene insect amide, Rynaxypyr, bromine cyanogen insect amide.
The present composition is also containing the auxiliary element needed for pesticidal preparations, comprise solvent, emulsifier, wetting agent, dispersant, antifreezing agent, thickener, disintegrant, binding agent, bleeding agent, defoamer, stabilizing agent, macromolecule cyst material, pH adjusting agent, film forming agent, synergist, liquid-carrier and solid carrier etc., it is all composition that is conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
The present composition can be prepared into the multiple application forms being applicable to agriculturally using, reasonable formulation has suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wetting powder, microcapsule suspending agent, ultra low volume liquids and granule, the production technology of various application forms all belongs to existing known technology, does not repeat them here.
