Abstract
The invention discloses a compound bactericide containing jinggangmycin and difenoconazole. The bactericide comprises the following raw materials in percentage by weight: 0.1 to 70 percent of the jinggangmycin, 0.1 to 70 percent of the difenoconazole, 1 to 15 percent of dispersant, 1 to 15 percent of wetting agent, 1 to 5 percent of antifreeze agent, 0.1 to 5 percent of preservative, 0.1 to 5 percent of defoaming agent, 0.1 to 5 percent of thickener, and the balance of water. Tests prove that the compound bactericide can be used for effectively preventing and controlling rice sheath blight and other epiphyte diseases.
Description
Technical field
The present invention relates to a kind of agricultural double-crossed disinfectant, specifically a kind of composite bactericide that contains jinggangmeisu and Difenoconazole.This invention can be used for preventing and kill off fungal diseases such as rice sheath blight disease.
Technical background
Paddy rice is the important cereal crops of China, and sowing area accounts for 1/4 of national cereal crops, and output accounts for over half.Rice sheath blight disease claims moire disease again.Generally begin morbidity in tillering stage, occur water stain shape elliptical spot at first on the leaf sheath of the nearly water surface, later scab increases, and normal healing mutually becomes the moire shape spot of irregular big shape, and its edge is a brown, middle part celadon or filbert.Basic identical on symptom on the blade and the leaf sheath.Disease is expanded from bottom to top, can go up sword-like leave when serious, even causes the morbidity of fringe portion, large stretch of lodging.Banded sclerotial blight is mainly survived the winter in soil with sclerotium.The sclerotium of 1 year showy water surface is sprouted and is grown mycelia, immerses leaf sheath immediately and forms scab, grows mycelia again near the new scab of formation that spreads from scab.When sclerotium falls into the water and can borrow current to propagate.Excessive nitrogen fertilizer application, high dense planting, the dark too much or inclined to one side nitrogen fertilizer application of pouring water is the principal element of bringing out disease.Paddy rice reaches onset peak since the morbidity in tillering stage around the booting stage, the state of an illness descends after milk ripe stage.
Jinggangmeisu is the water soluble antibiotics-glucoside compounds that is produced by the mutation of water streptomycete well ridge.Have 6 components, main active substances is jinggangmycin A and B.Jinggangmeisu is the very strong agricultural antibiotic of a kind of systemic action, after the mycelia of rice sheath blight disease pathogen touches jinggangmeisu, can be absorbed very soon and in thalline, conduct, and disturb and the growth of inhibition somatic cells normal growth, thereby play therapeutic action by somatic cells.Difenoconazole is a kind of triazole bactericidal agent sterol demethylation inhibitor; to Ascomycetes, Basidiomycetes and comprise Alternaria, Ascochyta, the mould genus of tail spore, Colletotrichum, ball Cuo Pseudomonas, Phoma, Ramularia, Septoria, Venturia partly know disease, Erysiphaceae, Uredinales and some are planted and are passed pathogen lasting protection and therapeutic action are arranged.
Difenoconazole is a kind of low toxicity, have the bactericide of protection, treatment and interior suction; be characterized in wide spectrum, efficient, low toxicity, low-residual and to people and animals and Environmental security; to suppressing the biosynthesis of cell wall sterol; can stop the crop fungi growth; fungicidal spectrum is wide, thereby becomes one of present China suitability for industrialized production large-tonnage agricultural chemicals.
Suspending agent (SC) be insoluble or the former medicine that is slightly soluble in water by some auxiliary agent, be scattered in more equably in the water by the wet method ultramicro grinding, form a kind of particle higher suspension slightly, liquid-solid attitude system that can be fluidly stable.Suspending agent normally is made up of active ingredient and " five doses " (dispersant, thickener, antiprecipitant, defoamer, antifreezing agent) and water, and content of effective is generally 5%-50%, and the average particle diameter is about 3um.Because (dispersiveness and plate-out ability) is all relatively good, and the suspensibility height for " two property " of suspending agent, the ability that sticks to the plant corpus surface is more intense, resistance of rainwater washing against.So the drug effect of said preparation is remarkable than wetting powder, and the drug effect phase is longer.
Jinggangmeisu and Difenoconazole are carried out composite, not only can strengthen medicament in plant corpus surface adhesive capacity, and can also improve protection effect, reduce the loss that disease caused.
Up to the present, patent does not also have the composition of mentioning jinggangmeisu and two kinds of Fungicidal compounds of Difenoconazole both at home and abroad.
Summary of the invention
The object of the present invention is to provide a kind of composite bactericide that contains jinggangmeisu and Difenoconazole.
Another object of the present invention provides a kind ofly can effectively prevent and kill off the disinfectant use in agriculture of rice sheath blight disease.The objective of the invention is to be achieved through the following technical solutions:
Composite bactericide of the present invention is characterized in that it is to contain two kinds of active components, i.e. jinggangmeisu and Difenoconazole.
Composite bactericide of the present invention is characterized in that each constituent content of suspending agent of described jinggangmeisu and Difenoconazole is (mass fraction): jinggangmeisu 0.1-70%, Difenoconazole 0.1-70%, dispersant 1-15%, wetting agent 1-15%, antifreezing agent 1-5%, preservative 0.1-5%, defoamer 0.1-5%, thickener 0.1-5%, water surplus.
This is invented compared with prior art, has fully proved through land for growing field crops drug effect extend trial and has adopted composite bactericide of the present invention to have following advantage and good effect:
(1) composite bactericide of the present invention can be realized " two delay " (delay drug-fast development, delay the medicament life cycle).
(2) composite bactericide of the present invention can be realized " two reductions " (reducing agricultural chemicals usage amount, reduction plant protection cost on the unit are).
(3) composite bactericide of the present invention can be realized " two increases " (increase rice yield, increase farmers' income).
(4) composite bactericide of the present invention can be realized " two minimizings " (reduce the persticide residue of agricultural chemicals on paddy rice, reduce the pollution of agricultural chemicals to environment).
