Description

A kind of bactericide that contains tridemorph

Technical field

The present invention relates to technical field of pesticide, specifically, relate to a kind of bactericide that contains tridemorph.

Background technology

Bactericide is the one type of agricultural chemicals that is used to prevent and treat the plant disease that is caused by various pathogenic microorganisms, refers generally to fungicide.But in the world, normally as the general name of medicament of all kinds of pathogenic microorganisms of control.Along with the development of bactericide, distinguish subclass such as bactericide, virucide, algicide again.According to investigations, the whole world pathogenic microorganism (fungi, strong bacterium, rickettsia, mycoplasma, virus, algae etc.) harmful to plant has more than 80,000 kinds.Using bactericide is a kind of cost-effective method of controlling plant diseases.

Early stage bactericide all is an inorganic compound, is wherein still using so far like Cosan and copper agent (like bordeaux mixture).Twentieth century four the fifties, developed the organosulfureous fungicides that three main series are arranged: beautiful type of good fortune, generation gloomy type of (like zineb) and trichloro-methylthio diformazan carboxylic acid imide, organochlorine, organic mercury, organoarsenic fungicide also have development in addition.These bactericide are protectant mostly, and limitation is arranged in the application.Since the sixties, more the bactericide of polyvoltine type constantly occurs, and wherein most important progress is the appearance of systemic fungicide.Meanwhile, farm antibiotics also has development faster.Organic mercury, organo-arsenic and some organochlorine bactericide are because of toxicity or problem of environmental pollution gradually are eliminated.The systemics bactericide of a new generation further enlarges the market of bactericide owing to control efficiency improves.To the eighties, the kind of bactericide is above 200 kinds.

At present, bactericide various in style, wherein; Tridemorph is a kind of interior absorption wide-spectrum bactericide, has protection and treatment double action, can be absorbed in the plant corpus through root, stem, the leaf of plant; And move up at xylem, but the transfer of having only slight extent in wound skin zone influences because of receiving climatic factor after the dispenser; So the lasting period is unstable, and be easy to generate pesticide resistance.

Fluoxastrobin: pure article are white crystalline solid; Former medicine is a brown solid, is methoxy acrylic bactericide, efficient, wide spectrum; Nearly all mycota disease such as powdery mildew, rust, glume blight, net blotch, downy mildew, rice blast etc. all there is good activity; Can be used for cauline leaf spraying, seed treatment, also can carry out soil treatment, be mainly used in cereal, paddy rice, peanut, grape, potato, fruit tree, vegetables, coffee, lawn etc.

Kresoxim-methyl: former medicine is the white powder crystalline solid, is a kind of efficient, wide spectrum, new type bactericide, and diseases such as powdery mildew of strawberry, melon powdery mildew, powdery mildew of cucumber, pear scab are had good preventive effect.Kresoxim-methyl not only has the bactericidal activity of wide spectrum, simultaneously with excellent protection and therapeutic action, does not have cross resistance with other bactericide commonly used; And it is longer than the conventional sterilization agent lasting period; Have the selectivity of height, to crop, people and animals and beneficial organism safety, pollution-free basically to environment.

Fluoxastrobin: the mechanism of action is the same with Fluoxastrobin and other methoxy acrylic bactericides with characteristics, also is the mitochondrial respiratory inhibitor, promptly shifts through electronics between cytochrome b and C1 and suppresses mitochondrial breathing.The fluoxastrobin application period is wide, no matter grows like spore germination, germ tube in early days and intrusion leaf portion at fungal infection, still at growth period of hypha extraordinary protection and therapeutic action can both be provided, but infect the most effective to spore germination and initial stage.Because of the systemic activity of the excellence that has, it can be by fast Absorption, and can transmit to the top equably in leaf portion, so have good resistance of rainwater washing against ability.

The phonetic phenol of second: belong to heterocyclic nitrogen-group fungicide, pure article outward appearance is white powdery solid, and former medicine outward appearance is white powdery solid.To the actual preventive effect of many crop powdery mildews such as strawberry, watermelon, cucumber, grape, safe to crop.

Difenoconazole: systemic fungicide, have protection and therapeutic action, be sterol demethylation inhibitor; Suppress the biosynthesis of cell wall sterol; Stop fungi growth, be widely used in crops such as fruit tree, vegetables, fungicidal spectrum is wide; Can effectively prevent and treat scab, anthrachose of grape, white rot, spot defoliation, powdery mildew, brown spot, rust, yellow rust, head blight etc.Difenoconazole is that safety is than higher in the triazole bactericidal agent, and foliar treatment or seed treatment can improve output and the guaranteed quality of crop.

Flusilazole: systemic fungicide, can suppress the sterol demethylation, destroy and stop the biosynthesis of ergosterol; Cause cell membrane not form, make germ dead, effective to disease due to sac fungi, basidiomycetes and the imperfect fungus; Invalid to oomycetes, pear scab there is special efficacy.Mainly can be used for preventing and treating Ascomycetes, Basidiomycetes and Fungi Imperfecti fungi, like venturia inaequalis, white powder germ, the wheat class nuclear cavity bacteria of cereal class, Septoria bacterium, snag shell bacterium etc., the various pathogens on Guignardia and the sweet Lay, leaf spot of peanut.

Propiconazole: interior absorption triazole bactericidal agent with protection and therapeutic action; Can be absorbed by root, stem, leaf portion, and can be soon in the plant strain body on conduction, the control sac fungi; The disease that basidiomycetes and imperfect fungus cause; Particularly to take-all, powdery mildew, rust, root rot, water rice bakanae disease, sigatoka have the better prevention effect.

Fluorine ring azoles: interior absorption triazole bactericidal agent; Its active component fluorine ring azoles suppresses the synthetic of germ ergosterol; Hinder the formation of germ cell wall; And fluorine ring azoles molecule has powerful compatibility to a kind of fungal enzyme (14-dencthylase), compares with present known bactericide, can more effectively suppress the germ fungal pathogens.Fluorine ring azoles can improve all fourth matter enzymic activitys of crop; Cause the contraction of fungi haustorium; Suppress germ and invade, diseases such as the anthracnose on leaf spot, powdery mildew, rust and the grape on the crops such as banana, green onion garlic, celery, Kidney bean, melon, asparagus, peanut, beet, white rot are had good preventive effect.Absorption is strong in the fluorine ring azoles, can be absorbed by plant rapidly and conducts to susceptible position, disease is infected immediately stop, and local dispenser control thoroughly.And the lasting period is splendid, and as reaching more than 40 days in the bacteriostasis on the cereal, effect is stayed in remarkable holding, and has reduced medication number of times and labour costs.

Fluorine bacterium azoles: belong to the hypotoxicity bactericide, be ergosterol demethylation inhibitor, have prevention, treat, root out effect, the systemic action conductivity is good, and anti-rain drop erosion can be prevented the sick fixed evil of various crop.Be applicable to the control of powdery mildews such as wheat class, fruit tree, vegetables, rust, peach brown rot.

Fludioxonil: belong to the wide-spectrum bactericide of non-internal-absorting, through the relevant transfer of inhibition glucose phosphorylated, and the growth of inhibition fungal mycelium, finally cause germ dead.The mechanism of action is unique, does not have cross resistance with existing biocide agent.Suitable crop: wheat, barley, corn, pea, rape, paddy rice, ornamental crops, xylocarp, vegetables Lay, grape and lawn etc.Controlling object: as the blade face bactericide, be used for the rotten sickle spore bacterium of control snow, wheat net bunt bacterium, rhizoctonia solani etc., gray mold is had special efficacy; As seed treatment, be mainly used in cereal and the fragrant-flowered garlic cereals crop control kind of biography and soil-borne disease bacterium such as Alternaria, Ascochyta, aspergillus, sickle spore bacterium bits, long wriggle spore bits, Rhizoctonia and Penicillium bacterium etc.
