Description
Technical field
The present invention relates to a kind of control medicament of rice blast.
Background technology
Rice blast claims again rice blast, is one of three the most serious large diseases of hazard rice, can cause the significantly underproduction of paddy rice, underproduction 40%-50% when serious, and even No kernels or seeds are gathered, as in a year of scarcity.Rice blast all has generation throughout the country, occurs as manyly with leaf portion, joint portion, and main Types has seedling pest, leaf pest, joint pest, panicle blast and grain acne.
Rice blast pathogen is survived the winter on sick paddy, sick grass with conidium and mycelium, sprouts and produce conidium under good growing weather condition, borrows air-flow to propagate, and belongs to polycyclic disease.It is prerequisite that method for integrated control takes to eliminate the bacterium source of surviving the winter, and selects centered by disease-resistant variety, and Healthy culture is basis, and chemical control is auxiliary Comprehensive Control Strategy, generally to select disease-resistant variety and chemical control to attach most importance to.
Aspect rice blast chemical control, the biological control medicament by national agriculture chemical registration is bacillus amyloliquefaciens, bacillus subtilis at present, chemical control medicament is tricyclazole, kasugarnycin, cytosintetidemycin, fenoxanil, propiconazole, Isoprothiolane, carbendazim, prochloraz, tolelofos-methyl, chlorine nalidixic bacterium ester, own azoles alcohol, Tebuconazole, jinggangmeisu, Difenoconazole, cyprodinil, triazolone, iprobenfos, thiophanate-methyl, sulphur, prochloraz-manganese chloride complex, edifenphos, phosethyl-Al, alkene azoles alcohol, S-Ethyl ethylthio sulfonate, tmtd, oxime bacterium ester, pungent bacterium amine acetate, polyoxin, this thiazole of Western-style pastry, the single dose of tpn etc. or complex preparation.Biological control weak effect, takes effect slow, can not meet the needs of agricultural production; The good medicament of chemical control preventive effect is tricyclazole, and the good medicament of result for the treatment of is kasugarnycin.
By the single dose of national agriculture chemical registration kasugarnycin, be mainly used in preventing and treating rice blast, fusarium wilt, leaf mold, angular leaf spot, wildfire at present; Relevant complex preparation, as the complex preparation with chlorobromide isocyanuric acid, sulphur, Isoprothiolane, for preventing and treating rice blast; Composite with carbendazim, for preventing and treating anthracnose; With the complex preparation of prochloraz-manganese chloride complex, for preventing and treating rust; With the complex preparation of Cupravit, be used for the treatment of canker, downy mildew, leaf mold, peronospora tabacina.But on the whole, aspect rice blast prevents and treats, the good medicament of integrated control effect is the complex preparation of tricyclazole and kasugarnycin, and control efficiency is 70%-80%.
CN200710085999.4(publication number is CN101258851A) a kind of production technology by amino-oligosaccharide-kasugarnycin and soluble powder that nutritive element forms disclosed.Its ratio of components is: amino-oligosaccharide 0.2%-12%, kasugarnycin 1-20%, nutritive element 98.8-68%, described nutritive element is mineral salt and the chelates thereof such as B, Zn, Mn, Fe, Mo.
For this reason, be necessary to provide the better rice blast control of a kind of prevention and result for the treatment of medicament.
Summary of the invention
The object of this invention is to provide a kind of rice blast control medicament.
The control medicament of a kind of rice blast of the present invention, its active component contains kasugarnycin and Portugal's polyene sugar.
Concrete, the active component of described control medicament contains following weight portion composition: kasugarnycin 0.1-55.0 Fen He Portugal polyene sugar 0.1-25.0 part.
Preferably, the active component of described control medicament contains following weight portion composition: kasugarnycin 0.1-50.0 Fen He Portugal polyene sugar 0.1-20.0 part.
In control medicament provided by the invention, also comprise solubility filler, described solubility filler is the conventional various solubility fillers in this area, according to those skilled in the art's common practise, the mineral salt or the organic matter that preferably contain plant nutrient ingredient, as the mineral salt or the organic salt that contain potassium, phosphorus, magnesium, calcium, manganese, copper, zinc, ammonium etc., the urea that contains nitrogen etc., are specially calcium chloride, potassium chloride, manganese chloride, magnesium chloride, ammonium chloride, urea, ferrous sulfate, zinc sulphate, copper sulphate, ammonium sulfate, magnesium sulfate, calcium acetate or potassium dihydrogen phosphate.
In above-mentioned control medicament:
Described weight portion can be the known unit of weights of pesticide field such as μ g, mg, g, kg, can be also above-mentioned known unit of weight multiple, as one of 10 times, 100 times, 1/10th, percentage.
Control medicament provided by the invention is preparation well known in the art, preferred solvable pulvis and aqua.
The present invention also provides the preparation method of above-mentioned control medicament, and the method comprises the following steps: according to proportioning, take each composition, mix, obtain.
The present invention also provides the application of above-mentioned control medicament in the agricultural chemicals of preparation control rice blast.
Control medicament provided by the invention generally adopts foliage-spray, and its effective ingredient consumption is generally 2-3g/ mu, and active ingredient spraying concentration is generally 50-80ppm.Those skilled in the art can adjust consumption as required.
The control medicament of rice blast provided by the invention has the following advantages:
1, in control medicament provided by the invention:
Kasugarnycin (kasugamycin), have another name called kasugarnycin, chemical name: (5-amino-2-methyl-6-(2,3,4,5,6-hydroxy-cyclohexyl oxo) tetrahydropyran-3-base) amino-α-IMDA, is the metabolite that actinomycetes produce, and sterling is white, needle-shaped crystals solid, hydrochloride is soluble in water, in 25 ℃ of water, dissolves 12.5%(W/V); Stable at normal temperatures, stable under acid and neutrallty condition, under alkali condition, easily decompose.Absorption antibiotic in kasugarnycin belongs to, the micro-poison of toxicity, for preventing and treating various bacterial disease and fungal disease, has preventive and therapeutic action concurrently, is the special-purpose antibiotic of control rice blast.
Portugal's polyene sugar, belongs to polysaccharose bioactivator, is a kind of novel plant resistance to environment stress derivant, and micro-poison is soluble in water.Portugal's polyene sugar can produce the protective plant protecting agent that can kill pathogenic microorganism by inducing plant as external source regulatory factor, reduces the generation of various crop disease; Can also be as the effective Promoting plant growth of growth regulator, branch, bloom, every metabolic activity such as result, improve crop yield.
Research finds, after above-mentioned two kinds of active principle kasugarnycin and Portugal's polyene sugar are mixed, to have synergy, can significantly increase the effect of control rice blast.
The agricultural chemicals of the control rice blast of 2, applying in production is at present the single dose of bactericide or the complex preparation of bactericide and bactericide, and control efficiency is poor.
3, the active ingredient of rice blast control medicament of the present invention is mixed and is formed by antibiotic kasugarnycin and active polysaccharide Portugal polyene sugar, utilize the synergy of antibiotic bactericidal activity and active polysaccharide induction of resistance, strengthen control efficiency, generation and the development of prevention and control rice blast.The present invention prevents and treats rice blast and has preventive and therapeutic action concurrently, and medication optimum period is long, and after premorbid or morbidity, use all can reach significant control efficiency.
