Abstract
The invention discloses Tebuconazole bactericidal agent belonging to the technology of bactericidal agent in the field of plant protection. The invention comprises tebuconazole 10-800 parts, humectant20-40 parts, dispersing agent 20-40 parts, disintegrant 20-80 parts, adsorbent 10-50 parts, adhesion agent 10-60 parts, stabilizing agent 10-80 parts and filler 50-500 parts. The above components aremixed according to a certain proportion, homogeneously agitated, disintegrated for mesh powder, mesh powder and adhesion agent are homogeneously mixed, and then the Tebuconazole water dispersible granule is achieved after granulation, drying and riddling. The invention overcomes the defects of prior Tebuconazole agent, decreases the application costs for farmers and environment pollution. Besides, the invention has the advantages of high content, rapid disintegration, good dispersibility, convenient storage, stability, high activity degree, good effect and safety.

Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, active ingredient is Tebuconazole, and formulation is water dispersible granules and preparation method thereof.Be mainly used in the control of wheat powdery mildew, sigatoka, alternaria leaf spot of apple, pear scab.
Background technology
At present; disinfectant use in agriculture is a lot; Tebuconazole is wherein a kind of, belongs to systemic fungicide, has protection and treatment double action; ergosterol biosynthesis inhibitor; can be rapidly partially absorbed and mainly shift by plant is vegetative, not only have bactericidal activity, can also promote plant growth to the top; make it that well developed root system, leaf look dark green, robust plant, effective tiller increase, thereby improve output.Can prevent and treat wheat powdery mildew, sigatoka, alternaria leaf spot of apple, pear scab effectively.And water dispersible granules has not only reduced peasant's use cost, and has reduced the pollution to environment, and the present invention in use has content height, fast, the good dispersion of disintegration, is beneficial to the advantage of storing and stability, and activity is high, usefulness is good, safety.
Wheat powdery mildew: be that China wheat belt threatens one of maximum disease, all can large tracts of land take place every year, distributed pole extensively and extremely difficult control, present single agent product can't effectively have been controlled disease and take place, and continues in rising trend in some areas incidence.
Sigatoka: in banana producing region, China south generation being arranged all, is the topmost disease of banana, incidence of disease height, the extent of injury is big, directly causes the serious underproduction of banana, no commodity value, plant is had very big influence, and present single agent product can't reach desirable preventive effect, and consumption is big, cost is high.
Alternaria leaf spot of apple: claim brown line disease again, spread over northern apple producing region in recent years, many orchards have become one of main disease, and the blade of causing harm causes caducously, and also cause harm young sprout and fruit influence tree vigo(u)r and output.
Pear scab: be a kind of quarantine venereal disease evil, mainly directly invade the people from plant leaf blade, fruit, the climing epidermis of stem, also can invade from pore and wound, disease portion begins depression to occur, is the silly shape of dun sore, and flows out translucent jelly, then become amber, diseased tissues stops growing, bending, and when not deliquescing, without putrefaction, high humidity, sick portion produces the mould layer of black.
Summary of the invention
Wood of the present invention be improve low, an easy packing of use cost, storing is convenient, do not have injury and an environmentally safe while and improved the availability and the medication efficient of effective ingredient again the people is healthy, overcome prior art cost height, polluted greatly, storage inconvenient shortcoming far away.Another purpose is to be prepared into outstanding formulation and easy to use, the high high-content water-dispersion granula of practical efficiency.
Technical scheme among the present invention and such realization, its composition of a kind of tebuconazole water dispersible granule comprises: Tebuconazole 10-800 part, wetting agent 20-40 part, dispersant 20-40 part, disintegrant 20-80 part, adsorbent 10-50 part, adhesive agent 10-60 part, stabilizing agent 10-80 part, filler 50-500 part.Wherein, the required auxiliary agent type of agent is found in aqueous dispersion according to claim 1, prepares according to the product concrete condition.
Owing to add the auxiliary agent of heterogeneity, make active quantities height of the present invention among the present invention, pollutes little, availability height, convenient, the stable easily use of storing.Have also that disintegration rate is fast, the advantage of good dispersion, good fluidity.
The preparation method's of a kind of tebuconazole water dispersible granule of the present invention technology, the technical indicator of product is as follows:
Tebuconazole content 1-80%
