Technical field
The present invention relates to a kind of bactericidal composition containing SYP-3375, belong to technical field of compounded pesticide.
Background technology
Methoxy acrylic acid series bactericidal agent is bactericide kind newly developed in recent years, is a large milestone in bactericide field.Methoxy acrylic bactericide has unique mechanism of action, and it stops the ATP of cell to synthesize by the electron transmission pinned between cytochrome b and c1, thus suppresses its mitochondrial respiratory and play bacteriostasis.Bacterial strain 14-demethylation enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole being produced to resistance is effective.There is protection, treat, root out, permeate, systemic activity, and to degrade very soon in plant corpus, in soil and water.Although this series bactericidal agent mechanism of action is unique, the speed that pathogen produces resistance to it is also very fast, and use cost is high, so the spread limiting methoxy acrylic acid series bactericidal agent uses.
SYP-3375 is a kind of methoxy-methyl acrylate compounds, English common name: coumoxystrobin, chemical name: (E)-2-(2-((3-butyl-4-methyl-coumarin-7-base-oxygen base) methyl) phenyl)-3-methoxy-methyl acrylate.There is protection and therapeutic action; be a kind of disinfectant use in agriculture of high-efficiency broad spectrum, have good preventive effect to by mastigomycetes, the plant disease such as sclerotinia rot of colza, apple valsa canker, cucumber downy mildew, rice blast, sigatoka, the alternaria leaf spot of apple etc. that cause in conjunction with bacterium, sac fungi, basidiomycetes and imperfect fungus.
Oomycete belongs to Mycophyta, and be a guiding principle of Mastigomycotina, Oomycete mainly contains pythium spp, phytophthora, downy mildew etc., often causes the downy mildew of crop, epidemic disease, damping off etc.The medicament preventing and treating this kind of disease conventional has dimethomorph, metalaxyl, Propamocarb, phosethyl-Al agricultural chemicals and mixture thereof.
Dimethomorph, has another name called peace gram, English common name dimethomorph, chemical name: (E, Z)-4-[3-(4-chlorphenyl) 3-(3,4-Dimethoxyphenyl) acryloyl] morpholine.Single-mindedly kill Oomycete fungal bactericide, its action character is the formation destroying cell envelope, effect is had to each stage of oomycetes history of life, be widely used in the disease control that vegetable downy mildew, epidemic disease, seedling sudden fall ill, black shank etc. are caused by Mastigomycotina Oomycete fungal, tool systemic activity.Be used alone higher resistance risk.
Metalaxyl; other title: the spirit of Apron, conservation, metalaxyl, auspicious poison frost, the white peace of first, the many Mils of thunder; English common name metalaxyl; chemical name: D; L-N-(2; 6-3,5-dimethylphenyl)-N-(2 '-methoxyl group acetyl) methyl lactamine; for acid amide fungicides; there is interior absorption; there is protection and therapeutic action, can be absorbed by the root, stem and leaf of plant, have Bidirectional Conduction performance; to the various crop downy mildew that Pseudoperonospora cubensis, phytophthora root rot bacterium and rotten mildew fungus cause, phytophthora root rot, the millet downy mildew of gourd, fruit and vegetable class are effective.
Metalaxyl-M; English common name metalaxyl-M; chemical name N-(2; 6-xylyl)-N-(Methoxyacetyl)-D-alanine methyl esters; Metalaxyl-M than metalaxyl to higher as disease activity, excellent to the crop pest preventive effect such as vegetables, fruit tree, tobacco, oil plant, cotton, grain caused by Pseudoperonospora cubensis, phytophthora root rot bacterium, rotten mildew fungus.
M 9834, English common name benalaxyl, chemical name: N-phenylacetyl group-N-2,6-xylyl-DL-Alanine methyl esters.M 9834 is systemic fungicide.For preventing and treating oomycetes diseases, as the single shaft mould of grape, potato, strawberry, the phytophthora of tomato, tobacco, onion, the downy mildew of soybean, the false downy mildew etc. of cucumber.
Propamocarb, has another name called Pu Like, epidemic disease frost is clean, English common name Propamocarb.Propamocarb belongs to carbamate fungicide, has local systemic action preferably.Its mechanism of action suppresses the phosphoric acid of germ cell membrane component and the synthesis of fatty acid, suppresses mycelial growth to spread and sporangial formation and spore germination.Propamocarb is a kind of wide-spectrum bactericide, effective especially to algae Gammaproteobacteria fungi, and to downy mildew, epidemic disease is mould, corruption is mould etc., and fungi has good killing action, also can make impregnation process and seed protectant.Be applicable to the various crop such as the vegetables such as cucumber, tomato, pimento, lettuce, potato and tobacco, strawberry, flowers, fruit tree.
Phosethyl-Al, has another name called Yimeiling, the spirit of epidemic disease frost, fosetyl aluminium, and mould epidemic disease is clean, Methylpartricin Sodium Laurylsulfate, mould spirit, English common name phosethyl-Al, chemical name: three-(ethylphosphonic acid) aluminium.Phosethyl-Al is systemic fungicide, to disease tool special efficacy caused by oomycetes, can conduct up and down in plant corpus, has protection and therapeutic action.
Frost urea cyanogen, English common name cymoxanil, chemical name: 1-(2-cyano group-2-methoxyl group imido grpup)-3-ethyl carbamide.Frost urea cyanogen is a kind of efficient, low toxicity bactericide, to Peronosporales fungi as epidemic disease frost genus, Peronospora, single shaft frost belong to effectively.Frost urea cyanogen is how mixed with other protective fungicides, is applicable to the vegetables such as cucumber, grape, tomato, lichee, fruit tree and tobacco etc.
Cyazofamid, the chloro-2-cyano group of English common name cyazofamid, chemical name: 4--N, N-dimethyl-5-p-methylphenyl imidazoles-1-sulfonamide.Cyazofamid is sulphaguanidine azoles fungicide.Super protective fungicide, also has certain interior suction and therapeutic activity.To the plasmodiophora brassica bacteria of Oomycete fungal as downy mildew, Pseudo peronospara, phytophthora, pythium spp and Plasmodiophoromycetes, there is very high biologically active.Controlling object downy mildew, epidemic disease are as cucumber downy mildew, downy mildew of garpe, tomato late blight, potato late blight etc.
Fluopicolide, the chloro-5-trifluoromethyl of English common name fluopicolide, the chloro-N(3-of chemical name: 2,6-bis--2-pyridine radicals) methyl) benzamide.Fluopicolide is botanical fungicide, and protectiveness is good, permeability is strong, has higher biologically active to oomycetes diseases, has good control efficiency.Can conduct from leaves of plants basal orientation blade tip direction.To crop and Environmental security, be specially adapted to high-quality, green vegetables are produced.
Although SYP-3375 is a kind of disinfectant use in agriculture of high-efficiency broad spectrum, it is as methoxy acrylic ester compounds, and the mechanism of action is single, Field information is reused for a long time germ and can produce resistance, cause preventive effect to reduce, and use cost is high.Above-mentioned dimethomorph, metalaxyl, Propamocarb etc. prevent and treat the special agricultural chemicals of Oomycete, the speed that pathogen produces resistance to it is also very fast, use separately dosage increasing, with conventional dose as mancozeb agriculture chemical compounding, use resistance to strengthen year by year for many years, also there is no the patent report of these agricultural chemicals and SYP-3375 mixture at present.Inventor is found by test; by SYP-3375 different for the mechanism of action and prevent and treat the bactericide compounded of Oomycete class disease; there is obvious synergistic effect; treatment, the control efficiency protected can be significantly improved, reduce spraying times and dosage; slow down the generation of germ resistance; reduce cost accounting, high to crop safety.
