Description
Patent application of the present invention is dividing an application of following patent.
Invention and created name: a kind of bactericidal composition that contains SYP-3375;
The original bill applying date: 20110831;
Original bill application number: 201110253025.9.
Technical field
The present invention relates to a kind of bactericidal composition that contains SYP-3375, belong to technical field of compounded pesticide.
Background technology
The methoxy acrylic acid series bactericidal agent is in recent years bactericide kind newly developed, is a large milestone in the bactericide field.Methoxy acrylic bactericide has unique mechanism of action, and it stops the ATP of cell synthetic by the electronics transmission of pinning between cytochrome b and c1, thereby suppresses its mitochondrial respiratory and bring into play bacteriostasis.The bacterial strain that 14-demethylation enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole is produced to resistance is effective.There is protection, treat, root out, infiltration, systemic activity, and can be in plant corpus, degraded very soon in soil and water.Although this series bactericidal agent mechanism of action uniqueness, the speed that pathogen produces resistance to it is also very fast, and use cost is high, so limited the spread of 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-Ji-oxygen base) methyl) phenyl)-3-methoxy-methyl acrylate.There is protection and therapeutic action; a kind of disinfectant use in agriculture of high-efficiency broad spectrum, to by mastigomycetes, the plant disease that causes in conjunction with bacterium, sac fungi, basidiomycetes and imperfect fungus, as sclerotinia rot of colza, apple valsa canker, cucumber downy mildew, rice blast, sigatoka, alternaria leaf spot of apple etc., good preventive effect being arranged.
Oomycete belongs to Mycophyta, is a guiding principle of Mastigomycotina, and Oomycete mainly contains pythium spp, phytophthora, downy mildew etc., often causes downy mildew, epidemic disease, damping off of crop etc.Prevent and treat this class disease medicament commonly used dimethomorph, metalaxyl, Propamocarb, phosethyl-Al agricultural chemicals and mixture thereof are arranged.
Dimethomorph, have another name called the peace gram, English common name dimethomorph, chemical name: (E, Z)-4-[3-(4-chlorphenyl) 3-(3,4-Dimethoxyphenyl) acryloyl] morpholine.It is single-minded ovicidal Gammaproteobacteria fungi bactericide, its effect characteristics are to destroy the formation of cell envelope, stages to oomycetes history of life has effect, be widely used in vegetables downy mildew, epidemic disease, seedling stage damping off, black shank etc. by the fungus-caused disease control of Mastigomycotina Oomycete, the tool systemic activity.Use higher resistance risk is arranged separately.
Metalaxyl; other title: Apron, conservation spirit, metalaxyl, auspicious poison frost, the white peace of first, the many Mils of thunder; English common name metalaxyl; chemical name: D; L-N-(2; the 6-3,5-dimethylphenyl)-N-(2 '-methoxyl group acetyl) methyl lactamine; for acid amide fungicides; interior absorption is arranged; there is protection and therapeutic action, can be absorbed by the root, stem and leaf of plant, the Bidirectional Conduction performance is arranged; the various crop downy mildew that Pseudoperonospora cubensis, phytophthora root rot bacterium and rotten mildew fungus are caused, 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; the 6-xylyl)-N-(methoxyl group acetyl group)-D-alanine methyl esters; Metalaxyl-M than metalaxyl to higher as the disease activity, to crop pest preventive effect excellences such as the vegetables due to Pseudoperonospora cubensis, phytophthora root rot bacterium, rotten mildew fungus, fruit tree, tobacco, oil plant, cotton, grains.
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 the Oomycete disease, as the single shaft mould of grape, potato, strawberry, the phytophthora of tomato, tobacco, onion, the downy mildew of soybean, the false downy mildew of cucumber etc.
Propamocarb, have another name called Pu Like, epidemic disease frost only, English common name Propamocarb.Propamocarb belongs to carbamate fungicide, has local systemic action preferably.Its mechanism of action is to suppress the phosphoric acid of germ cell membrane component and synthesizing of fatty acid, suppresses mycelial growth and spreads and sporangial formation and spore germination.Propamocarb is a kind of wide-spectrum bactericide, effective especially to algae Gammaproteobacteria fungi, and mould to downy mildew, epidemic disease, the rotten fungi such as mould 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, have another name called Yimeiling, the spirit of epidemic disease frost, and fosetyl aluminium, 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 due to oomycetes, in plant corpus, can conduct up and down, 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, and the Peronosporales fungi is belonged to effectively as epidemic disease frost genus, Peronospora, single shaft frost.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, English common name cyazofamid, the chloro-2-cyano group-N of chemical name: 4-, N-dimethyl-5-p-methylphenyl imidazoles-1-sulfonamide.Cyazofamid is the sulphaguanidine azoles fungicide.Super protective fungicide, also have certain interior suction and therapeutic activity.The Oomycete fungi is had to very high biologically active as the plasmodiophora brassica bacteria of downy mildew, false downy mildew, phytophthora, pythium spp and Plasmodiophoromycetes.Controlling object downy mildew, epidemic disease are as cucumber downy mildew, downy mildew of garpe, tomato late blight, potato late blight etc.
Fluopicolide, English common name fluopicolide, the chloro-5-trifluoromethyl of 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, and the Oomycete disease is had to higher biologically active, 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 production.
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, reuses for a long time germ in the application of field and can produce resistance, cause preventive effect to reduce, and use cost is high.Above-mentioned dimethomorph, metalaxyl, Propamocarb etc. are prevented and treated the special-purpose agricultural chemicals of Oomycete, the speed that pathogen produces resistance to it is also very fast, use separately dosage increasing, with conventional dose as the mancozeb agriculture chemical compounding, use for many years resistance to strengthen year by year, the patent report that does not also have these agricultural chemicals and SYP-3375 to be mixed at present.The inventor finds by test; the different SYP-3375 and prevent and treat the bactericide compounded of Oomycete class disease by the mechanism of action; there is obvious synergistic effect; can significantly improve control efficiency, minimizing spraying times and the dosage for the treatment of, protection; slow down the generation of germ resistance; reduce cost accounting, high to crop safety.
