Abstract

The invention discloses a prochloraz-containing fungicide, which is characterized by comprising an active compound prepared through compounding a fungicide A and a fungicide B, wherein the ratio of the fungicide A to the fungicide B is (1-80):(1-80); the fungicide A is prochloraz; and the fungicide B is one of the following fungicides: kresoxim-methyl, azoxystrobin, fluoxastrobin, flusilazole, triflumizole and fludioxonil. Compared with the prior art, the prochloraz-containing fungicide disclosed by the invention is prepared from the fungicide A and the fungicide B which are compounded together, and through the compounded application of the fungicides A and B, the production of drug resistance of germs to the prochloraz is slowed down, the duration period of the prochloraz-containing fungicide is prolonged, and meanwhile, an extremely strong synergistic effect of the prochloraz-containing fungicide is achieved.

Description

A kind of bactericide that contains Prochloraz

Technical field

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

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; Prochloraz belongs to the imidazoles bactericide; Be a kind of efficient, wide spectrum, low toxicity type bactericide, have multiple actions such as prevention, protection and treatment, work through the biosynthesis that suppresses sterol; No systemic action, splendid for the multiple diseases preventive effect that sac fungi and imperfect fungus cause.Though, Prochloraz to prevent and treat disease effect effect relatively good,, through abuse for a long time, germ has produced slight pesticide resistance to it.

Kresoxim-methyl: former medicine is the white powder crystalline solid, is a kind of efficient, wide spectrum, new type bactericide, and powdery mildew of strawberry, muskmelon are had good preventive effect from diseases such as powder disease, powdery mildew of cucumber, pears scab.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: 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.

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.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.

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.

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 the lasting period is long, 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.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.

Summary of the invention

The objective of the invention is to overcome the defective of prior art, a kind of bactericide that contains Prochloraz is provided.

For addressing the above problem, the technical scheme that the present invention adopted is:

A kind of bactericide that contains Prochloraz is characterized in that: it comprises that wherein, the proportioning of bactericide A and bactericide B is: 1-80: 1-80 by bactericide A and the composite former medicine that forms of bactericide B;

Said bactericide A is a Prochloraz; Said bactericide B is an optional one of which in the following bactericide: kresoxim-methyl, Fluoxastrobin, fluoxastrobin, Flusilazole, fluorine bacterium azoles, fludioxonil.

Say that further the proportioning of said bactericide A and bactericide B is: 3: 1.

Furtherly, said bactericide be missible oil, micro emulsion, water and milk, suspending agent (comprising: do outstanding, water is outstanding and oil outstanding), all formulations such as pulvis, soluble liquid, wetting powder, granula, soluble powder, water dispersible granules or suspension emulsion.

Owing to adopted technique scheme, compared with prior art, the present invention adopts bactericide A and forms with bactericide B is composite, and composite use has slowed down germ to the drug-fast generation of Prochloraz, the prolongation lasting period, and very strong synergistic effect is arranged.

Below in conjunction with embodiment the present invention is further specified.
