Description
Technical field
The present invention relates to a kind of pesticide control of rice blast.
Background technology
Rice blast is also known as rice blast, and be one of the most serious three large diseases of hazard rice, can cause the paddy rice significantly underproduction, underproduction 40%-50% time serious, even No kernels or seeds are gathered, as in a year of scarcity.Rice blast all has generation throughout the country, occurs as many 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 produces conidium, propagate by means of air-flow, belong to polycyclic disease under good growing weather condition.Method for integrated control is taked, to eliminate premised on bacterium source of surviving the winter, to select centered by disease-resistant variety, and based on Healthy culture, chemical control is auxiliary Comprehensive Control Strategy, under normal circumstances to select disease-resistant variety and chemical control to attach most importance to.
In rice blast chemical control, be bacillus amyloliquefaciens, bacillus subtilis by the biological control medicament of national agriculture chemical registration 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, olefin conversion, 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.
At present 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; 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, in rice blast is prevented and treated, 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) disclose a kind of by amino-oligosaccharide-kasugarnycin and nutritive element form the production technology of soluble powder.Its ratio of components is: amino-oligosaccharide 0.2%-12%, kasugarnycin 1-20%, nutritive element 98.8-68%, and described nutritive element is mineral salt and the chelates thereof such as B, Zn, Mn, Fe, Mo.
For this reason, the rice blast pesticide control that a kind of prevention and therapy better effects if is provided is necessary.
Summary of the invention
The object of this invention is to provide a kind of rice blast pesticide control.
The pesticide control 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 pesticide control contains following parts by weight ingredient: kasugarnycin 0.1-55.0 part and Portugal's polyene sugar 0.1-25.0 part.
Preferably, the active component of described pesticide control contains following parts by weight ingredient: kasugarnycin 0.1-50.0 part and Portugal's polyene sugar 0.1-20.0 part.
Also soluble filler is comprised in pesticide control provided by the invention, described soluble filler is the various soluble filler that this area is commonly used, according to the common practise of those skilled in the art, mineral salt preferably containing plant nutrient ingredient or organic matter, as the mineral salt containing potassium, phosphorus, magnesium, calcium, manganese, copper, zinc, ammonium etc. or organic salt, urea etc. containing nitrogen, is 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 pesticide control:
Described weight portion can be the known unit of weights of pesticide field such as μ g, mg, g, kg, also can be above-mentioned known unit of weight multiple, as 10 times, 100 times, 1/10th, one of percentage.
Pesticide control provided by the invention is preparation well known in the art, preferred solvable pulvis and aqua.
Present invention also offers the preparation method of above-mentioned pesticide control, the method comprises the following steps: take each composition according to proportioning, mix, to obtain final product.
Present invention also offers the application of above-mentioned pesticide control in the agricultural chemicals of preparation control rice blast.
Pesticide control 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 pesticide control of rice blast provided by the invention has the following advantages:
1, in pesticide control 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, be the metabolite that actinomycetes produce, sterling is white, needle-shaped crystals solid, hydrochloride is soluble in water, in 25 DEG C of water, dissolve 12.5%(W/V); Stablize at normal temperatures, stable under acidity and neutrallty condition, easily decompose in the basic conditions.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 antibiotic of control rice blast.
Portugal's polyene sugar, belonging 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 killing pathogenic microorganism by inducing plant as external source regulatory factor, reduces the generation of various crop disease; Can also as the effective Promoting plant growth of growth regulator, branch, bloom, every metabolic activity such as result, improve crop yield.
Research find, above-mentioned two kinds of active principle kasugarnycin and Portugal's polyene sugar mixture after, there is synergy, can significantly increase control rice blast effect.
2, the agricultural chemicals producing the control rice blast applied at present is 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 pesticide control of the present invention is formed by antibiotic kasugarnycin and active polysaccharide Portugal polyene sugar mixture, utilize the synergy of antibiotic bactericidal activity and active polysaccharide induction of resistance, strengthen control efficiency, the generation of prevention and corntrol rice blast and development.The present invention prevents and treats rice blast and has preventive and therapeutic action concurrently, and medication optimum period is long, and premorbid or the rear use of morbidity all can reach significant control efficiency.
