Abstract

The invention relates to a flusilazole and pyraclostrobin compounded suspending bactericide and a preparation method thereof, which belong to the technical field of pesticides. The suspending bactericide is prepared from the following components by weight percentage under the condition that the content of flusilazole is 95% and the content of pyraclostrobin is 98%: 0.1 to 40% of flusilazole, 0.1 to 40% of pyraclostrobin, 0.1 to 2% of an antifoaming agent, 0.5 to 20% of a wetting agent, 0.5 to 20% of a dispersant, 0.1 to 4% of an antifreezing agent, 0.1 to 5% of a thickening agent, 0.1 to 4% of a pH value conditioning agent, 0.1 to 10% of a stabilizing agent and 0.1 to 5% of an osmotic agent, with the balance being deionized water. The suspending bactericide has the characteristics of high efficiency, low toxicity, no pollution, no damage to environment, human beings and livestocks and low resistance generating possibility of pathogen.

Description

technical field [0001] The invention relates to a fungicide suspension compounded with flusilazole and pyraclostrobin and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Pesticide preparations are gradually developing towards safety, environmental protection, and water-based. Pesticide suspension concentrates have the following advantages: ① no dust hazard, safe for operators and the environment; ② using water as the dispersion medium, there is no flammable and Injury problem; ③Compared with wettable powder, it is allowed to use different particle sizes of the original drug, so as to achieve the best biological effect and physical stability of the preparation; ④Liquid suspension spreads well in water and can be directly made into spray liquid Use; ⑤ specific weight, small packaging volume. ⑥The dispersibility and spreadability of the suspension are relatively good, the suspension rate is high, the ability to adhere...
