Description
Technical field
The present invention relates to a kind of mixed pesticide technology, relate to specifically a kind of compound sterilization preparation and application thereof being formed by pyraclostrobin, Difenoconazole, propiconazole compound.
Technical background
Pyraclostrobin
Its mechanism of action of pyraclostrobin is mitochondrial respiratory inhibitor.Make mitochondria can not produce and provide cell eubolism institute energy requirement, finally cause cell death.It can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete.Growth to spore germination and leaf intramatrical mycelium has very strong inhibitory action, has protection and therapeutic activity.Have permeability and local systemic activity, the lasting period is long, resistance of rainwater washing against.
Difenoconazole
The commodity Difenoconazole by name of Difenoconazole (english common name difenoconazole), opposes the pellet that withers, and generation is high.Formulation products has 3% suspension seed-coating agent, and 10% aqueous dispersion can granula.
Propiconazole
Universal Chinese character title: propiconazole
English common name: propiconazole
Chemical name: 1-[2-(2,4-dichlorophenyl)-4-propyl group-DOX-2-methyl]-1 hydrogen-1,2,4-triazoles
Molecular formula: C15H17Cl2N3O2
Molecular weight: 342.2
Former medicine outward appearance is faint yellow sticky silk fabric liquid, 180 ℃ of boiling points (13.3Pa), vapour pressure (20 ℃) 0.133mPa, index of refraction 1.5468, proportion (20 ℃) 1.27g/cm3.In water, solvability is 110mg/L, is soluble in organic solvent.320 ℃ following stable, more stable to light, is hydrolyzed not obvious.More stable in acid, alkaline medium, corroding metal not.
Propiconazole is a kind of interior absorption triazole bactericidal agent with protection and therapeutic action; can be absorbed by root, stem, leaf portion; and can be soon in plant strain body on conduction; control sac fungi; the disease that basidiomycetes and imperfect fungus cause; particularly to take-all, powdery mildew, rust, root rot, water rice bakanae disease, sigatoka has good control efficiency.
The main medicament of processing with regard to rice paddy seed below and prevent and treat the situation of disease, is described below:
The U.S. favourable incoming road chemical industrial company develops defends good fortune (active ingredient: carboxin, tmtd) 40% suspending agent, is mainly used in preventing and treating rice seedling blight (160～200g/hm2), bakanae disease (120～160g/hm2).
The Frontline that Rhone-Poulenc Company develops (active ingredient: ethiprole) 5% seed dressing, be mainly used in rice hoppers, rice leaf roller, rice thrips, rice gall midge (80～160g/100kg seed, assorted effect rice: 20～40g/kg, conventional Rice).
The good year winter (active ingredient: carbosulfan, 35% seed treatment, for preventing and treating rice thrips (210～400g/100kg seed), rice gall midge (600～800g/100kg seed) that U.S. Fu Meishi company develops.
Above three kinds of external seed treatment kinds, although obtain registration in China, its price is high, is difficult to spread at home.
Bakanae disease, main line parasitosis, rice blast, banded sclerotial blight, bacterial leaf-blight and the helminthosporium leaf spots etc. of paddy rice of causing harm are many to be propagated by seed and Soil infection.On rice paddy seed, with a lot of pathogens, can, in rice strain growth different times, stage, show various disease symptom.
By seed transmission, there are bakanae disease, main line sick.Bakanae disease is mainly passed the winter with seed, after seed germination, infects seedling basal part of stem and passes sick; And by Soil infection, propagated have banded sclerotial blight, rice blast, a bacterial leaf-blight etc.Wherein banded sclerotial blight generation area is maximum, and the incidence of disease is the highest, and the field underproduction rate of being injured is up to more than 50%, its mainly with remain in sclerotium in soil survive the winter pass sick.After seed-borne disease occurs, the growth of rice strain, growth, output, quality are had to impact in various degree.
Secondly, because seed rice carries disease germs, be the first dip-dye source that causes rice strain morbidity, in the season of growth, can cause infecting again, occur, spread, endangering of disease.Traditionally, the control to seed-borne disease, present stage people adopt always and before broadcasting, carry out seed treatment and eliminate seed-borne disease, and make seed and seedling exempt from causing harm of soil-borne disease and insect.Bactericide kind for the bactericide seed treatment of seed treatment is a lot, has inorganic with organic, volatile or nonvolatile, interior suction or non-interior suction.After preparation, with pulvis, water solube powder, wetting powder, emulsion, liquor or suspending agent, use.A good seed treatment should not leave any the Harmful Residue that affects seed sprouting, seedling development, plant strain growth and product.
