The invention discloses a dinotefuran and isoprocarb compound suspending agent and a preparation method thereof, relating to the technical field of control of plant diseases and insect pests of rice and ornamental flowers. The compound suspending agent is prepared from the following components in parts by weight: 6 parts of dinotefuran, 24 parts of isoprocarb, 3 parts of fatty alcohol-polyoxyethylene ether, 5 parts of phenethyl phenol polyoxyethylene ether, 0.5 part of xanthan gum, 0.3 part of sodium benzoate, 0.5 part of an antifoaming agent and 60.7 parts of deionized water. The preparation method comprises the following steps: introducing all the raw materials into a preparation vessel, mixing and stirring, performing preliminary grinding on the mixture by virtue of a colloid mill, performing fine grinding by virtue of a sand mill, sampling, analyzing, filtering, metering, packing and warehousing after the product is qualified. The 30% dinotefuran and isoprocarb compound suspending agent is formed by mixing dinotefuran and isoprocarb according to a ratio of 1:4, an obvious synergistic effect can be achieved, and the other preparations mixed according to the ratio cannot achieve the obvious synergistic effect. Meanwhile, the actual toxicity of different ratios is not improved along with increase of theoretical toxicity, and regular change does not exist between the actual toxicity and the theoretical toxicity.

The invention relates to the technical field of pesticide for controlling rice sheath blight diseases and false smut, in particular to a suspending agent of thifluzamide and tebuconazole composite pesticide and a preparation method of the suspending agent. The suspending agent is prepared by the following ingredients in parts by weight: 20 parts of thifluzamide, 32 parts of tebuconazole, 18 parts of emolsifier and 30 parts of solvent. The prepared suspending agent is obviously superior to products prepared according to other proportions in suspensibility, persistent foamability, wet sieving test, thermal stability and the like. Experiments verify that the cotoxicity coefficient of the suspending agent reaches 154.19, the suspending agent falls in an obvious synergistic action scope, and preparations mixed in other proportions cannot reach the obvious synergistic action scope. In addition, the actual toxicity of different proportions is not raised with theoretical toxicity, and no change law exists between the actual toxicity and the theoretical toxicity. The suspending agent of the thifluzamide and tebuconazole composite pesticide is suitable for controlling the rice sheath blight diseases and the false smut, and has good popularization and application values.
