Description
Technical field
The invention belongs to technical field of pesticide, are related to a kind of bactericidal composition of fluorine-containing indenes azoles bacterium amine.
Background technology
Fluorine indenes azoles bacterium amine chemical name:3- difluoromethyls-N- (the fluoro- 2,3- dihydros -1,1,3- trimethyls -1H- indenes -4- of 7-
Base) -1- methyl-1 H- pyrazole-4-carboxamides, belong to wide spectrum SDHI series bactericidal agents, fungicidal spectrum covers all thifluzamides and Lu Na
Gloomy fungicidal spectrum, in addition to Rhizoctonia solani special efficacy, all to anthrax, rust, early blight, powdery mildew, leaf mold, false smut preventive effect
Very well.It will be high than Lu Nasen, green prince wife's activity especially in terms of powdery mildew.Structural formula is as follows:
Fludioxonil category wide spectrum, non-interior suction pyrroles series bactericidal agent, draw many pathogens such as sac fungus, basidiomycetes, Fungi Imperfecti
The kind risen passes and soil-borne disease has extraordinary preventive effect, inhibits mycelia to give birth to by inhibiting the related transhipment of glucose phosphorylated
It is long, eventually lead to germ death.Its unique mechanism of action does not have cross resistance with other known fungicide.Suitable for crop
Wheat, barley, corn, pea, rape, rice, ornamental crops, hard fruit and vegetable Lay, grape and lawn etc., as foliage fungicide
Rotten Fusariumsp, wheat net bunt bacterium, rhizoctonia solani etc. are avenged for preventing, has special efficacy to gray mold;As seed treatment:It is main
It is used to prevent kind of biography and soil-borne disease bacterium such as Alternaria, Ascochyta, aspergillus, a Fusariumsp in cereal and fragrant-flowered garlic cereals crop
Bits, long compacted spore bits, Rhizoctonia and Penicillium bacterium etc..
Azoles mepanipyrim is a kind of highly selective triazolo pyrimidine series bactericidal agent, belongs to mitochondrial respiratory inhibitor, can be efficient
Neatly prevent downy mildew and late blight.The product resistance of rainwater washing against, can redistribute in blade, cover crop health at
It is long, give full play to growth potential.
Cyprodinil chemical name:There is 4- cyclopropyl -6- Methyl-N-phenyl pyrimidine -2- amine protection, treatment, blade to wear
Saturating and root systemic activity is mainly used for preventing gray mold, powdery mildew, scab, net blotch, glume blight and wheat eyeprint disease
Deng, to crop safety, no poisoning.
Amisulbrom chemical name:3- (the fluoro- 2 methyl indole -1- bases sulfonyls of the bromo- 6- of 3-)-N, N- dimethyl -1H-
1,2,4- triazole -1- sulfonamide, is the triazolylsulfonamide series bactericidal agent of Japanese Nissan exploitation, and amisulbrom is sterilized for contact killing type
Agent has certain osmotically active and good resistance of rainwater washing against ability, has very high activity to epidemic disease and downy mildew, especially
It is very high to germ spore activity of dissociating, can inhibit fungi breathing and spore germination, be a medicament aimed at prevention.Indazole
Flusulfamide is mainly used for preventing potato blight, downy mildew of garpe, cucurbit downy mildew and brassica vegetable clubroot etc..
Fluorine thiazole pyrrole ethyl ketone chemical name 1- (4- { 4-[(5RS) -5- (2,6- difluorophenyls) -4,5- dihydro -1,2- Evil
Azoles -3- Jis ]- 1,3- thiazol-2-yls } -1- piperidyls) -2-[5- methyl -3- (trifluoromethyl) -1H- Bi Zuo-1-Jis ]Ethyl ketone is
The newly developed first piperidyl thiazole isoxazoline series bactericidal agent of E.I.Du Pont Company.Fluorine thiazole pyrrole ethyl ketone has very favorable toxicity
Learn and environmental characteristics, dosage is also few, higher to the safety of user, agricultural producer and environment, to cause potato and kind
The phytophthora infestans of eggplant blight are efficient.Fluorine thiazole pyrrole ethyl ketone activity is high, effective to phytophthora infestans each stage of development, can be in host
