    P34260BE00 / RR BE2019 / 5736 Title: Preparation of pyrazole ether Mycobacterium ester prothioconazole suspending agent and suspension seed coating agent Technical field The present invention belongs to the field of pesticide production and use, in particular to the formulation development and application of a 12% water suspending agent from prothioconostrobin and pyraclonazrobin.
    Background technology Water suspending agents are becoming increasingly popular with users due to their environmental protection, their high efficiency, their practical application, their low production costs and their low pollution.
    This is the main direction for the development of green pesticide preparations.
    When processing water suspending agents, the suspension system of the water suspending agent is very different due to the different content of reagent and additives.
    Pyraclostrobin is one of the strobilurin fungicides with high efficiency and a broad spectrum; Prothioconazole is a triazole fungicide with good endoscopic and biological activity.
    Drug compounding is one of the effective ways to expand the bactericidal spectrum and to delay drug resistance.
    Pyraclostrobin and prothioconazole belong to fungicides with different mechanisms of action and can play a very complementary synergistic role after mixing.
    Currently, the water suspending agent has some problems such as crystallization, aggregation and sedimentation.
    A good additive system can compensate for these deficiencies in the water suspending agent and play a very good role.
    SUMMARY OF THE INVENTION The object of the present invention is to provide a process for the preparation of a 12% pyraclostrobin-prothioconazole water suspending agent and its use for combating wheat scab and rust disease.
    The bactericide combination preparation is stable and has a good control effect.
    It can achieve very good multi-prevention by spraying once.
    The present invention offers the following technical solution: The preparation of the 12% pyraclostrobin-prothioconazole water suspension medium is carried out according to the following steps (the amount of reagents is not limited to this): Please take 6% prothioconazole and 6% pyraclostrobin, mix emulsifier, thickener , Antifreeze and other ingredients, fill up with 100% water,
    -2- BE2019 / 5736 grind to 3-5 µm with a sand grinder, add defoamers and other substances, mix evenly to make suspending agents.
    Among them, the emulsifier is preferably selected from one or more compositions of sodium lignin sulfonate, NNO, polyethylene glycol, castor oil and ethylene oxide condensate, sorbitan fatty acid ester, JFC, etc.
    The thickener is preferably selected from one or more compositions of magnesium aluminum silicate, xanthan gum, R-cyclodextrin, sodium carboxymethyl cellulose, polyvinyl alcohol and penetration agent JFC.
    The antifreeze is selected from one or more compositions of ethylene glycol, glycerin, glycerin and urea.
    The grinding time is 0.3-1 hour.
    The water suspending agent made by this invention has the advantages of stable performance, uniform spray particle size and a high suspension rate.
    The water suspending agent made by this invention has the advantages of a short meal, energy saving and reduced consumption. The production method with water as a carrier also corresponds to the concept of environmentally friendly development of pesticide preparations.
    The 12% pyraclostrobin-prothioconazole water suspending agent produced by this invention can be used not only to control and prevent wheat scab, rust disease and mildew, but also to coat peanuts, soybeans, corn, wheat, rice and other crops by adding pigments and film formers be used.
    The 12% pyraclostrobin-prothioconazole water suspending agent disclosed by the invention differs from the suspending agent in other previously disclosed patents. Compared to the disclosed suspending agent, the water suspending agent disclosed by the invention has more advantages in terms of storage stability and use on site. The advantages of the present invention are: (1) The total content of the two suspending agents is limited to 12%. It is not only suitable for spraying, but also for coating; (2) it can prevent many diseases of wheat and other crops by single-spray multi-prevention, which is very effective, convenient to use and lowers the cost; (3) The physical properties of the suspension agent produced are more stable and the droplet size is more uniform when sprayed.
