Embodiment 1

[0015] Embodiment 1, 50% thiamethoxam · thifuramide wettable powder

[0016] 25% of thiamethoxam, 25% of thifluzamide, 10% of fatty alcohol polyoxyethylene ether, 6% of pulling powder BX, and 100% of bentonite. After the above-mentioned materials are uniformly mixed in a double-screw mixer, they are pulverized by a jet mill to a mesh size below 800 to obtain a 50% thiazide-thiazide wettable powder meeting the standard.

Embodiment 2

[0017] Example 2, 45% thiamethoxam boscalid water-dispersible granules.

[0018] 20% thiamethoxam, 25% boscalid, 7% alkylphenol polyoxyethylene ether, 6% sodium lauryl sulfate, 1% ammonium sulfate, 0.2% aluminum oxide, 5% starch, diatomaceous earth supplement to 100%. The above-mentioned material is made into water suspension, and the particle size of the particles in the suspension is pulverized and ground to below 5um with a pipeline crushing pump and a sand mill to make a water suspension, and the solid content in the suspension is adjusted to a suitable ratio. The suspending agent is pumped into a special spray granulation drying tower with a mud pump to prepare 45% thiamethoxam-boscalid water-dispersible granules that meet the standard.

Embodiment 3

[0019] Embodiment 3, 35% thiamethoxam · penthiopyrad suspension

[0020] Thiempyridone 17%, Penthiopyrad 18%, Fatty Alcohol Polyoxyethylene Ether 7%, Calcium Alkylbenzene Sulfonate 8%, Polyethylene Glycol 2%, Silicone Oil 0.2%, Propylene Glycol 3%, soft water to 100% %. The above materials are made into a suspension, and the suspension is crushed and ground by a pipeline crushing pump and a sand mill until the particle size of the particles in the suspension is below 5um, and a 35% thiamethoxam-pethiopyram suspending agent that meets the standard is prepared.

Abstract

The present invention discloses a bactericidal composition containing benziothiazolinone and succinic dehydrogenase inhibitor. The composition comprises two active components, a component A and a component B; the component A is benziothiazolinone, and the component B is a succinic dehydrogenase inhibitor fungicide selected from the group consisting of thifluzamide, boscalid, Penthiopyrad, Isopyrazam, biphenyl penthiopyrad, fluorine myclobutanil amide, Fluxapyroxad, penflufen, fluopyram or Benzovindiflupyr. The weight ratio of the component A and component B is 1:50-50:1, preferably 1:10-10:1. The composition can be prepared into a wettable powder, a water dispersion granule, a suspending agent and an emulsion in water for prevention and control of wheat rust, and downy mildew and epidemic diseases of vegetables, melons and fruits.

Description

technical field [0001] The invention relates to a bactericidal composition containing thiamethoxamin and a succinate dehydrogenase inhibitor, which belongs to the technical field of pesticide compounding. technical background [0002] Benziothiazolinone is an isothiazole heterocyclic compound, which is a high-efficiency, low-toxicity, broad-spectrum fungicide. Its mechanism of action is to combine with anions on the cell membrane surface of bacteria and fungi or react with sulfhydryl groups to destroy proteins and Synthetic system of cell membranes, thereby inhibiting the reproduction of bacteria and molds, interfering with the metabolism of pathogenic bacteria cells, making them physiologically disordered, and leading to the death of pathogenic bacteria. In 2008, Shanxi Xidahuate Technology Industrial Co., Ltd. developed and produced thiamethoxam, which was officially registered as the first pesticide by the Ministry of Agriculture, and has been widely promoted and applied....
