The insecticidal and bactericidal composition disclosed by the invention can be used for effectively preventing and treating various plant diseases and insect pests of rice and has the advantages of being wide in preventing and treating spectrum, relatively slow in resistance development, remarkable in synergic effect, low in preventing and treating cost and the like.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of pesticide-germicide composition pesticide for water prevention chilo suppressalis, rice leaf roller, banded sclerotial blight and rice blast.
Background technology
Fluoxastrobin (Azoxystrobin): belong to methoxy acrylic sterilization pesticide, efficiently, wide spectrum, to nearly all mycota (Ascomycotina, Basidiomycotina, Mastigomycotina and Deuteromycotina) disease, as powdery mildew, rust, glume blight, net blotch, downy mildew, banded sclerotial blight, rice blast etc. all have good activity.Can be used for cauline leaf spraying, seed treatment, also can carry out soil treatment, be widely used in the control of disease on cereal, paddy rice, peanut, grape, potato, fruit tree, vegetables, coffee, lawn.
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 paddy rice pesticide-germicide composition pesticide 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 pesticide for paddy rice 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 Fluoxastrobin, 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.
Composition pesticide of the present invention 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.
Composition pesticide of the present invention 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.
Composition pesticide of the present invention, is applicable to water prevention chilo suppressalis, rice leaf roller, banded sclerotial blight and rice blast.
Composition pesticide described in the invention, can finished product preparation form provide, namely in composition, each material mixes, and the composition of composition also can provide by unit dose form, directly mixes in bucket or tank, be then diluted to desired concn before using.
Composition pesticide provided by the invention, usually adopts spray-on process to use, also can adopt other operation techniques agriculturally applied as required.
Compared with prior art, the invention has the advantages that:
1, composition pesticide of the present invention has significant synergistic function, uses than single dose or binary built the control efficiency significantly improved damage by disease and insect, expands control spectrum simultaneously, has accomplished that a medicine is controlled more, damage by disease and insect is planted by Zhiduo County of holding concurrently.
2, composition pesticide of the present invention decreases Pesticide use amount, the service life reducing use cost, alleviate pollution to environment, delayed the drug-fast generation of damage by disease and insect, extended agricultural chemicals.
