Abstract
The invention relates to a pesticide composition for preventing and treating a fungal disease. Tebuconazole and bacillus subtilis are used as effective ingredients, the weight ratio of tebuconazole to bacillus subtilis is 10:1-1:4, additives and filler acceptable for pesticide are adopted, and a dispersing agent, a wetting agent, a disintegrating agent and/or a binding agent are adopted as the additives. The effective ingredients, tebuconazole and bacillus subtilis in the pesticide composition account for 1-5% of the product by weight. The drug form is a water dispersing agent. The composition has the advantages of not influencing the seed germinating stage of crops and having a synergistic effect of preventing and treating the fungal disease.
Description
Technical field
The invention belongs to technical field of pesticide, particularly to a kind of composition pesticide preventing and treating fungal disease, wherein effective ingredient is Tebuconazole and bacillus subtilis.
Background technology
Tebuconazole; chemical name: (RS)-1-(4-chlorphenyl)-4; 4-dimethyl-3-(1H-1; 2; 4 triazol-1-yl methyl) penta-3-alcohol; being a kind of efficient, wide spectrum, interior absorption triazole type sterilization pesticide, have protection, treat, root out three zones, fungicidal spectrum is wide, the lasting period is long. Tebuconazole is mixed even with seed stirring before being mainly used in crop seeding, then sows seed, to reach preventing and treating farm crop fungus infection effect, is particularly useful for preventing and treating loose smut of wheat. Dressing seed crop seeds is sprouted due to Tebuconazole and have inhibitory action, causing crop growth cycle stretch-out, thus affecting proportion of crop planting cost.
Bacillus subtillis is a kind of gram-positive bacterium being distributed widely in various different living environment, can sprout in producing born of the same parents, at the surface ubiquity of soil and plant, simultaneously or a kind of endophyte common in plant, to person poultry harmless, free from environmental pollution. Bacillus subtilis is applied to prevent and treat wheat scab relevant report; the preliminary study of wheat scab " the bacillus subtilis bacterial strain A014 bacterial strain prevent and treat " delivered by force such as Wang Yaping, Liu Yi is pointed out; gibberella saubinetii is had stronger bacteriostasis by bacillus subtilis bacterial strain A014; and have certain protection effect; make infection process rate reduce by 50%, can protect the wheat head not by the extension of infection process or restriction fringe portion pathogenic bacteria preferably.
At present, using Tebuconazole, bacillus subtilis as the preventing and treating crops germination period fungal infection of effective ingredient but without relevant report, both are optionally combined crops germination period without impact also to there is no prior art enlightenment, and prevent and treat and have potentiation on pathogenic bacteria.
Summary of the invention
It is an object of the invention to, it is provided that a kind of composition pesticide preventing and treating fungal disease, there is high-efficiency low-toxicity, reduce the using dosage of Tebuconazole and do not affect the advantages such as crops germination period.
To achieve these goals, the technical solution used in the present invention is:
A kind of composition pesticide preventing and treating fungal disease, including effective ingredient Tebuconazole and Bacillus subtillis, wherein Tebuconazole is 10:1��1:4 with the weight ratio of Bacillus subtillis, and acceptable auxiliary agent and filler on pesticide.
The weight ratio of described effective ingredient Tebuconazole and Bacillus subtillis is 5:1��1:2, it is preferred to 2:1.
Described auxiliary agent is dispersant, wetting agent, disintegrating agent and/or binding agent, the optional dodecyl sodium naphthalene sulfonate of wherein said dispersant or sodium methylene bis-naphthalene sulfonate, the optional sodium lauryl sulphate of wetting agent or dodecyl sodium sulfate, disintegrating agent may select carbamide, and binding agent may select xanthan gum.
Described filler may select Kaolin.
In described composition pesticide, shared by each component, mass percent is: effective ingredient Tebuconazole and Bacillus subtillis account for 1��5%, dispersant accounts for 3��12%, wetting agent accounts for 2��8%, disintegrating agent accounts for 1��8%, binding agent accounts for 0.001��5%, and surplus is filler.
In described composition pesticide percent mass shared by each component preferably than accounting for 2% for: effective ingredient Tebuconazole and Bacillus subtillis, dispersant accounts for 8%, wetting agent accounts for 5%, disintegrating agent accounts for 4.5%, binding agent accounts for 3%, surplus is filler.
Invention also provides the method preparing this composition pesticide, in proportion effective ingredient Tebuconazole is mixed together with Bacillus subtillis, dispersant, wetting agent, disintegrating agent and filler component, pulverizes; Add binding agent, obtain granulation materials, granulation materials are granulated, are drying to obtain, wherein granulate and dry employing fluidized bed process.
Described fluidized bed process is granulated and dry fluid is noble gas.
Described fluidized bed process is granulated and dry fluid temperature (F.T.) is 30��60 DEG C.
Described composition pesticide is water dispersant.
The present invention has the following advantages and significant technique effect:
(1) medicament high-efficiency low-toxicity, compares Tebuconazole, and the toxicity of people and animals is substantially reduced by medicament, it is to avoid the risk of production and application person poultry poisoning.
(2) active component Tebuconazole and Bacillus subtillis Synergistic, use with in the reasonable scope, can reduce the amount of application of each single dose, advantageously reduces drug cost and reduces environmental pollution.
(3) avoid because Tebuconazole suppresses seed germination to extend the agronomic crop seed germination phase, thus reducing proportion of crop planting cost.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with embodiment.
One, indoor joint toxicity measuring test
The indoor joint toxicity measuring test of Tebuconazole, bacillus subtilis and mixed agent thereof, active constituent content gradient series 5 concentration of dilution are pressed with Tebuconazole, bacillus subtilis and mixed agent thereof, compare with sterilized water, test with fusarium graminearum for for examination antibacterial, blank is set, Tebuconazole, bacillus subtilis single dose and mixture preparation thereof are adopted dip method, carries out toxicity test and do statistical analysis.
Evaluate the potentiation of pharmacy mix with the co-toxicity coefficient method (CTC) of the abundant method of Sun Yun, namely CTC��80 are antagonism, and 80<CTC<120 is summation action, and CTC>=120 are potentiation. Statistical result is as shown in table 1:
Table 1: Tebuconazole, bacillus subtilis and mixed agent thereof the Toxicity Determination table to fusarium graminearum
Showing according to table 1 measurement result, when the mixed ratio of Tebuconazole and bacillus subtilis is 12:1, co-toxicity coefficient (CTC) is 114.21, and both mixtures are summation action; When the mixed ratio of Tebuconazole and bacillus subtilis is 1:8, co-toxicity coefficient (CTC) is less than 80, and both mixtures are antagonism; When the mixed ratio of Tebuconazole and bacillus subtilis is 10:1��1:4 scope, co-toxicity coefficient (CTC) is all higher than 120, and namely potentiation is obvious, and wherein 2:1 potentiation is best.
