Description
Technical field
The invention belongs to pesticide field, being specifically related to a kind of bactericidal composition avenging rotten Fusariumsp for preventing and treating pea.
background technology
Avenge rotten Fusariumsp aerial hyphae light fleece shape or one-tenth pionnote on PSA medium, sticky spore layer is yellowish pink to honey gold.The root of infringement seedling, causes dead seedling.The root of infringement seedling, causes dead seedling, mostly occurs in 2 ~ 4 leaf phases of seedling.The sick seedling flavescence look of their early stage or darkviolet, root browning, namely wilts withered soon, and serious causing is short of seedling disconnected ridge.
Germ survives with mycelium or spore or survives the winter in soil, is soil-borne disease.The plot susceptible disease of temperature low, rainy time in general 5, June or hypsography low-lying, impeded drainage.
(1) crop rotation in more than 3 years is carried out.
(2) the plot cultivation millet of high and dry easy draining is selected.
(3) chemical control 35% Apron (metalaxyl) seed dressing is dressed seed or the wet-mixing that adds water by grain weight 0.2% ~ 0.3%, or 50% first frost copper wetting powder dislikes white bacterium pellet (Ceftlofur) wetting powder by grain weight 0.2% ~ 0.25% seed dressing by grain weight 0.3% ~ 0.4% seed dressing, 64% Sandofan wetting powder by the grain weight seed dressing, 80% of 0.4% ~ 0.5%.After dosing is mixed thoroughly, should sow immediately.
Fludioxonil is a kind of contact bactericide, can be used for seed treatment, can prevent and treat seed-borne fungi and soilborne fungal disease.
For wheat, barley, corn, pea, rape, paddy rice, vegetables, grape, lawn, ornamental crops leaf surface treatment, control snow rotten Fusariumsp, wheat net raw meat black rot, rhizoctonia solani etc., have special efficacy to gray mold; To cereal and non-cereal seed process, control kind passes and soil-borne disease bacterium, as Alternaria, Ascochyta, aspergillus, Fusarium, Helminthosporium, Rhizoctonia and Penicillium bacterium.
Fludioxonil is non-interior suction benzene pyroles suspension seed-coating agent, high-efficiency broad spectrum.Extraordinary preventive effect is had to the microbial kind biography of many cause of diseases such as sac fungi, basidiomycetes, imperfect fungus and soil-borne disease.It suppresses mycelial growth by suppressing the relevant transhipment of glucose phosphorylated, finally causes germ dead.The mechanism of action of its uniqueness, does not have cross resistance with the bactericide that other is known.When seed germination, fludioxonil can be absorbed on a small quantity, thus can control the germ of seed and caryopsis inside; Fludioxonil moves hardly in soil simultaneously, therefore, it is possible to be retained in the region around seed always, provides long-term protection to crop root.The formulation that fludioxonil is excellent in addition makes seed pelleting film forming fast, does not come off.Fludioxonil is to crop seed safety, and better tolerance, capsuled seed can directly be sowed, and also can put to next sowing sowing season under suitable storage requirement.Fludioxonil is one of product of whole world acquisition few in number EPA EPA " low-risk " certification.Fludioxonil is widely used in various crop, as cotton, wheat, peanut, soybean, paddy rice etc.
The Fluquinconazole mechanism of action and feature Main Function mechanism are sterol demethylation inhibitors, and the biosynthesis of the cell membrane important composition composition ergosterol of destruction and prevention germ, causes cell membrane not formed, and make germ dead.There is interior absorption, protection and therapeutic activity.
Suitable for crop wheat, barley, paddy rice, beet, rape, legume, vegetables, grape and apple etc.To under crop safety recommended dose to crop safety, without poisoning.Controlling object control by the fungus-caused multiple diseases of Basidiomycetes, Fungi Imperfecti and Ascomycetes as can Major Diseases on effectively preventing apple as apple scab and apple mildew, to following pathogen as Powdery Mildew, chain sclerotinia sclerotiorum, the mould genus of tail spore, Phoma, Septoria, bury the fungus-caused diseases such as Sclerotinia, Puccinia, hunchbacked spore Rust and nuclear disk mattress genus and all have good control efficiency.
