Abstract
The invention relates to a pesticide composition, in particular to a pesticide composition containing tebuconazole and validamycin A in effective dose for synergism, wherein the weight ratio of the tebuconazole to the validamycin A is preferably 10:1-1:10, more preferably 10:1-1:6, further preferably 1:1-1:6 and optimally preferably 1:3. The pesticide composition is particularly suitable for controlling false smut of rice.
Description
Technical field
The present invention relates to a kind of synergetic pesticide composition, particularly relate to a kind of synergetic pesticide composition that comprises Tebuconazole and jinggangmycin A.
Background technology
Tebuconazole (tebuconazole) is the wide spectrum triazole bactericidal agent by Bayer AG's exploitation, inhale therapeutic action in having, partially absorb and conduct by plant is vegetative to the top, suppress germ ergosterol demethylation, promote plant growth, make it well developed root system, the leaf look dark green, robust plant, effective tiller increases, thereby improves output.All effective to multiple germ, but lack the prevention protective effect, agricultural cost is also higher relatively.
The chemical structural formula of Tebuconazole is:
Jinggangmycin A is a kind of Glucosamine glycoside antibiotic that is produced by the mutation of streptomyces hygroscopicus well ridge.It is a desirable biopesticide of preventing and treating efficient, the low toxicity of rice sheath blight disease, apply nearly 30 in the period of, high yield, the stable yields of China paddy rice have been made significant contribution.But because long-term single use, develop immunity to drugs in some areas.
The applicant is through discovering in a large number, and Tebuconazole and jinggangmycin A are used with has unforeseeable control efficiency to preventing and treating rice disease such as rice sheath blight disease and false smut, and its synergistic effect is fairly obvious.And the two is used with, and paddy rice fungal diseases such as banded sclerotial blight and false smut have efficiently, quick-acting is good, the lasting period is long to preventing and treating, delay pesticide resistance, environmentally safe etc. characteristics, therefore are extraordinary paddy rice fungal disease control medicaments.In addition, the applicant finds still do not have relevant Tebuconazole and jinggangmycin A to be mixed at present and prevent and treat the play-by-play of paddy rice fungal disease control medicament by retrieval both at home and abroad.Based on above-mentioned discovery, the applicant has finished the present invention.
Summary of the invention
The object of the present invention is to provide a kind of mixed ratio reasonable, control efficiency is good, the synergetic pesticide composition that drug cost is low.
Another object of the present invention is to provide agricultural chemicals suspension agent (SC), wetting powder (WP), water dispersible granules (WG) and aqueous emulsion (EW), the solubility aqua preparations such as (SL) made by the formulated employing conventional production process of this composition pesticide.
Another object of the present invention is to provide the purposes that this composition pesticide is used to prevent and treat rice sheath blight disease and false smut.
Technical scheme of the present invention is as described below:
A kind of composition pesticide is characterized in that containing the Tebuconazole and the jinggangmycin A of synergy effective dose.
Wherein, the weight ratio of Tebuconazole and jinggangmycin A is preferably 10 in this composition pesticide: 1-1: 10, more preferably 10: 1-1: 6, more preferably 1: 1-1: 6, most preferably be 1: 3.
Composition pesticide of the present invention can be mixed with agricultural chemicals suspension agent (SC), wetting powder (WP), water dispersible granules (WG) and aqueous emulsion (EW), solubility aqua preparations such as (SL) according to the conventional production process of this area.Its administration form depends on specific application; In all cases, must guarantee that their dispersion is trickle as much as possible and even.
These preparations can prepare in a known manner, for example by reactive compound is mixed with liquid flux and/or solid carrier, if desired, surfactant such as emulsifier, dispersant, wetting agent can be added simultaneously, thickener, defoamer, antifreeze, oxidant, dyestuff etc. can also be added.If use water as thinner, also available other organic solvent is made cosolvent.
The organic solvent that is fit to comprises aromatic compound (for example dimethylbenzene), chlorinated aromatic hydrocarbons compound (for example chlorobenzene), paraffin (for example petroleum distillate), alcohols (for example methyl alcohol, ethanol), ketone (for example cyclohexanone), amine (for example monoethanolamine, dimethyl formamide) etc.
The synthetic mineral matter (for example high molecular silicic acid, silicate etc.) that solid carrier commonly used has natural mineral matter (for example kaolin, talcum, bentonite, attapulgite) and grinds.
Surfactant can be emulsifier, dispersant or wetting agent; Can be nonionic or ionic.For example, lauryl sodium sulfate, Teepol, neopelex, polyoxyethylene fatty acid ester, polyoxyethylene aliphatic alcohol ether, polyoxyethylene fatty amine or directly use the commercial emulsifier: agricultural newborn 0201B, 0203,0203B, 600# etc.Material as dispersant and wetting agent has: sodium lignin sulfonate, draw back powder, calcium lignosulfonate and sldium lauryl sulfate, alkylol polyoxyethylene groups ether sodium sulfate, octylphenol polyethylene oxyethylene group ether sulfate, alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, sodium alkyl sulfonate, neopelex etc.
Thickener; can be for example carbonyl methylol, polyvinyl alcohol or the polyvinyl acetate that synthesizes; or natural water-soluble polymer; for example xanthans, gelatin, gum Arabic, phenolic resins, shellac, carboxymethyl cellulose and sodium alginate etc. add in the preparation with powder, particle or latex form.
Defoamer is: bubble enemy, silicone, C
8-10Fatty alcohol, phosphoric acid ester, C
10-20Saturated fat acids (as capric acid) and acid amides etc.
Oxidant is: potassium chlorate, sodium chlorate, potassium perchlorate, sodium nitrate, potassium nitrate, potassium permanganate etc.
Antifreeze is urea, calcium chloride etc.
Usually composition contains 0.01 to 90% active component by weight, and usually according to the difference of preparation type, preferably contains 1 to 30% active component by weight.
The application dosage of the present composition, the difference according to factors such as Different Crop, time of application, weather conditions is generally 1-1000g a.i./ha, preferred 5-300g a.i./ha.The general foliage applying that adopts, for example foliar spray is used.
The present composition has the following advantages: the one, and composition shows fabulous synergistic effect in certain ratio range, mixed composition has obviously improved bactericidal effect than its single agent, thereby reduced application dosage, when reducing drug cost, reduced influence environment.The 2nd, enlarged fungicidal spectrum, a kind of medicament can be prevented and treated multiple diseases simultaneously; The present composition all has good therapeutic action to rice sheath blight disease, rice blast and false smut.
