This invention relates to the field of pesticide technology, specifically to a fungicidal composition, its preparation method, and its uses. The invention provides a fungicidal composition comprising an active ingredient, a first functional component, a second functional component, and an adjuvant; the active ingredient comprises fluthiazopyrone and cyazofamid; the first functional component comprises at least one selected from silica, titanium dioxide, and zinc oxide; the second functional component comprises at least one selected from citric acid, acetic acid, benzoic acid, urea, and triethanolamine. By introducing specific first and second functional components, this invention synergistically works with the active ingredient, effectively overcoming the key defects of fluthiazopyrone's easy photodegradation and cyazofamid's easy hydrolysis, thus improving the stability of the compound formulation; while ensuring the excellent control efficacy and resistance management advantages of both against oomycete diseases such as grape downy mildew, it extends the duration of action and weather resistance of the agent, providing a more stable, efficient, and long-lasting solution for field application.

The invention provides a matte adjustable resin composition and an asparagus polyurea matte coating composition, and relates to the technical field of coatings. The matte adjustable resin composition comprises the following raw material components: aspartic ester resin and an acrylate polymer, the weight ratio of the acrylate polymer in the matte adjustable resin composition is 5 to 30 percent; and the side chain of the acrylate polymer contains alkyl groups with C4 and longer carbon chains in a molar ratio of not less than 5%. According to the invention, a certain amount of acrylate resin with a specific structure is added into the aspartic polyurea coating and has certain incompatibility with aspartic ester resin, so that the matte performance of the aspartic polyurea coating can be obviously improved.

The invention provides a pyraclostrobin thioneb water dispersible granule and a preparation process thereof, and belongs to the technical field of pesticide preparations. The preparation process comprises the following steps: loading pyraclostrobin thioneb on modified tungsten trioxide nanoflowers; the micro-capsule of the tungsten trioxide nanoflower loaded with the pyraclostrobin metiram is flexible; preparing a polymer binder; preparing a nano auxiliary agent; and preparing the water dispersible granules. Pyraclostrobin thioneb is loaded by tungsten trioxide nanoflowers, and the tungsten trioxide nanoflowers have unique optical performance, can absorb and scatter light rays such as ultraviolet rays and reduce direct irradiation of the light rays to pyraclostrobin thioneb, so that decomposition and failure caused by photolysis of the pyraclostrobin thioneb are reduced, the validity period and the lasting period of the pesticide are prolonged, and the pesticide is safe and environmentally friendly. Meanwhile, the slow release speed of pyraclostrobin thioneb can be adjusted after modification of polyethylene glycol and lauryl sodium sulfate, so that the pesticide can continuously exert the pesticide effect on the surfaces of crops.
