Description
Technical field
The present invention relates to a kind of agricultural bactericidal composition and uses thereof, be specifically related to a kind of with fludioxonil with hymexazo is the bactericidal composition and the application thereof of main active.
Background technology
Crop is subjected to infecting of various diseases, particularly fungal disease easily in growth and development process, it is of a great variety, and harm is serious.Silborne fungal diseases is the difficult point of control of plant disease especially, and its infringement that plant growth and output are caused is from saying.For a long time, chemical control is the main effective means of preventing and treating soil-borne disease.Because unscientific tillage method is as continuous cropping for many years, make that germ accumulates all the year round in the soil, can not get effective removing, add single drug and other various unscientific application methods, cause multiple soil-borne pathogen that the agricultural chemicals of current use has been produced serious resistance.Because germ accumulates the generation resistance in a large number, cause the frequent dispenser of peasant to cause drug cost to increase and increasing environmental pollution.In some vegetables and melon and fruit planting base, the independent use of conventional pesticide has been difficult to play control efficiency.
Therefore, be badly in need of efficient, low toxicity, safety, environmental protection, the bactericide that helps resistance management and composition thereof and solve the problems referred to above.
Fludioxonil (fludioxonil) is the pyroles bactericide, it is the analog of the secondary metabolites pyrrolnitrin (pyrrolnitrin) that produces of (the Pseudomonas pyrrocinia) not of the same race of pseudomonas (Pseudomonas spp.), because it is than the anti-photodissociation of natural products pyrrolnitrin, can selectivity ground mould fungus inhibition and be widely used in fungal disease in the control agricultural production.The antibacterial mechanism of fludioxonil then is to suppress mycelial growth by suppressing the transhipment relevant with the glucose phosphorylated, finally causes the death of germ.For bacterial disease good effect is arranged also in addition.
Fludioxonil is used for the rotten sickle spore bacterium of control snow, wheat net bunt bacterium, rhizoctonia solani etc. as the blade face bactericide, and gray mold is had special efficacy; As seed treatment: be mainly used in cereal and the fragrant-flowered garlic cereals crop control and kind pass and soil-borne disease bacterium such as Alternaria, Ascochyta, aspergillus, Fusarium, Helminthosporium, Rhizoctonia and a Penicillium bacterium etc.But the fludioxonil cost is higher, is difficult to large tracts of land and promotes.
Hymexazo (hymexazol) is a heterocycle compound, is a kind of systemic fungicide, soil disinfectant, also is a plant growth regulators simultaneously.Can directly be absorbed, enter in the plant corpus, move very rapid by plant root.In root system, move and only just moved to stem in 3 hours, moved to the plant whole body in 24 hours.Mechanism of action uniqueness, efficient, low toxicity, nuisanceless can suppress mycelial normal growth of disease fungus or direct killing pathogenic bacteria, can promote plant growing again.Soil fungi all there is significant fungistatic effect as: sickle-like bacteria, root shell bacterium, rhizoctonia, pythium spp, the rotten bacterium of seedling, photovoltaicing leather bacteria etc., can be applicable to prevent and treat diseases such as damping off, seedling rot, damping off, fusarium wilt, verticillium wilt, stalk break, anthracnose, eqpidemic disease, dry rot, scab, sclerotium soft rot, seedling blight, stem wilt, leaf blight, to macerate root, continuous cropping continuous cropping obstacle has better effects.Hymexazo to the preventive effect of bacterial disease relatively a little less than, and because to prevent and treat the medicament kind of soil-borne disease less, using method is improper in the practical operation, the single use preventive effect of ， hymexazo obviously descends at present, the pesticide resistance problem occurs.
