Abstract
The invention relates to a sterilization composite containing cyazofamid and flusilazole and application of the sterilization composite. The sterilization composite comprises cyazofamid and flusilazole, wherein the weight ratio of cyazofamid to flusilazole is (40:1)-(1:60). The sterilization composite can be used for preventing and controlling diseases on commercial crops, cereal or flowers and plants, is wide in application range, excellent in effect, low in cost and residue, and safe to human, livestock, environment and the like.
Description
(1) technical field
The present invention relates to a kind of bactericidal composition and purposes, relate in particular to a kind of bactericidal composition that contains cyazofamid and Flusilazole, be mainly used in the control of economic crops disease.
(2) background technology
Cyazofamid (Cyazofamid, CAS 120116-88-3) is a kind of novel low toxicity bactericide, has good prolection and certain interior suction therapeutic activity, and the lasting period is long, and resistance of rainwater washing against is used safety, convenient.This medicine belongs to mitochondrial respiratory inhibitor, and its bactericidal mechanism is by suppressing the Qi in cytochrome b cl in germ metabolic process, and causes germ dead, is different from methoxyl group fluorine alkene esters of gallic acid medicament.All vegetative stages to oomycetes all have effect, and the germ that metalaxyl is produced to resistance or sensitivity all has activity.
Flusilazole (Flusilazole, CAS 85509-19-9) is triazole type wide-spectrum bactericide, and its mechanism of action is to suppress the biosynthesis of pathogen ergosterol, thereby cause cell membrane not form, reaches bactericidal action.After medicament is sprayed onto on plant, can be absorbed rapidly, and carry out Bidirectional Conduction, the systemic fungicide that therapeutic action is held concurrently in tool prevention.After Flusilazole spray medicine, a few hours are just infiltrated plant corpus, and distributivity is strong, the washout of resistance to rainwater, and the lasting period can reach 10～15 days.Mainly can be used for preventing and treating Ascomycetes, the fungus-caused disease of Basidiomycetes and Fungi Imperfecti.
Although cyazofamid has above-mentioned advantage, because cost is too high, at present domestic almost not application.Although Flusilazole drug effect is high, control spectrum is wide, application is also comparatively extensive at present, but the angle from pesticides application, the a certain agricultural chemicals of long-term single use, all easily cause preventive effect to reduce, the problem such as consumption increases, develop immunity to drugs, lasting period shortening, residual risk strengthens, and is unfavorable for environment harmonious development.Seeking scientific and rational agriculture chemical compounding, is to address this problem good way.At present at home and abroad there are no cyazofamid and the composite relevant report of Flusilazole.If both can be together composite, just can solve preferably the problem of above-mentioned appearance, the two is compared single dose after composite and has synergistic function simultaneously, improves the effect that single dose is used separately.Also there is no at present the composite relevant report of cyazofamid and Flusilazole at home and abroad.
(3) summary of the invention
One of object of the present invention is to overcome above-mentioned deficiency, provide a kind of applied widely, effective, consumption is low, cost is low, the lasting period is long, residual little and there is the bactericidal composition that contains cyazofamid and Flusilazole of synergistic effect.
Two of object of the present invention is to provide the purposes of a kind of bactericidal composition that contains cyazofamid and Flusilazole for control economic disease of pests evil.
The object of the present invention is achieved like this:
A bactericidal composition that contains cyazofamid and Flusilazole, the contained active component of described composition is cyazofamid and Flusilazole, the weight ratio of described cyazofamid and Flusilazole is 40:1～1:60.
The preferred weight ratio of described cyazofamid and Flusilazole is 3～35:5～45.
More preferably, the weight ratio of the two is 6:1～1:3;
Most preferred, the weight ratio of the two is 1:1.
Described combination dosage form is any one formulation allowing on agricultural chemicals.Such as wetting powder, water dispersible granules, suspending agent, aqueous emulsion, missible oil or seed coat agent etc.
Described cyazofamid and the Flusilazole percentage by weight in above-mentioned formulation is 5～85%.
Further, the invention provides a kind of purposes of the bactericidal composition that contains cyazofamid and Flusilazole as above, is for control economic disease of pests evil by described Bactericidal composite, preferably, described disease is: soybean downey mildew, phytophthora root rot, root rot, rust, tomato late blight, the climing rot of watermelon, fusarium wilt, cucumber downy mildew, powdery mildew, tea gall, bud blight, downy mildew of garpe, gray mold, white rot, anthrachose of grape, club root, tobacco downy mildew, balck shank, damping off, pear scab, rust, ring spot, rot, black spot, apple scab, brown spot, citrus anthracnose, foot rot, blossom-end rot, capsicum epidemic disease, leaf spot of peanut, damping off, sclerotinia rot of colza, potato late blight, cotton seedling blight, red rot, coffee rust, brown spot, mango anthracnose, sigatoka, scab, bunchy top, sheath maize ear rot etc.Be preferred for the control of sclerotinia rot of colza, pear scab, mango blossom-end rot, apple marssonina leaf spot and cucumber downy mildew.
Compared with prior art, the invention has the beneficial effects as follows:
(1) synergistic effect that the present composition is done well in certain ratio range, the bactericidal effect of composition has had and has significantly improved than single dose, and its co-toxicity coefficient is at least more than 120, has reduced agricultural chemicals using dosage and cost simultaneously, reduced residually, also alleviated the harmful effect to environment;
(2) in the present invention, the mechanism of action of two kinds of active components is different, and the application of composition can delay or overcome the resistance of pathogen, extends the service life of product;
(3) present composition is good to economic crops diseases control, in addition, also can be used for the control of its corps diseases.
(4) embodiment
In order to make object of the present invention, technical scheme and advantage clearer, the present invention describes with following instantiation, but the present invention is not limited to these examples.
