A thifluzamide, amino-oligosaccharin and hexaconazole compound suspending agent and its preparation method relate to the field of pest control techniques in paddy fields. The compound suspending agent is prepared from the following ingredients, by weight, 5 parts of thifluzamide, 5 parts of amino-oligosaccharin, 10 parts of hexaconazole, 4.5 parts of fatty alcohol-polyoxyethylene ether, 7.5 parts of styrylphenol polyoxyethylene ether, 1 part of xanthan gum, 0.5 part of sodium benzoate, 1 part of organosilicon and 6.5 parts of solvent naphtha. The preparation method comprises the following steps: pumping raw materials into a preparation vessel, mixing and stirring, carrying out preliminary grinding by a colloid mill, carrying out fine grinding by a sand mill, carrying out sampling analysis, filtering after qualified, metering, packaging and warehousing. The thifluzamide, amino-oligosaccharin and hexaconazole compound suspending agent has a good effect of controlling rice sheath blight disease and rice blast. The synergistic effect of the three ingredients thifluzamide, amino-oligosaccharin and hexaconazole is realized, and an obvious synergetic effect is achieved. Meanwhile, the compound suspending agent has a double effect of prevention and treatment and has a long persistent period. According to the compound suspending agent, its bactericidal activity is performed mainly by inhibiting demethylation of sterol in pathogenic fungus so as to block biofilm formation.

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.

The invention provides a pyrazosulfuron-ethyl, fenoxaprop-P-ethyl and penoxsulam compound dispersible oil suspension concentrate and a preparation method thereof, relating to the technical field of control of weeds in direct sowing paddy fields. The pyrazosulfuron-ethyl, fenoxaprop-P-ethyl and penoxsulam compound dispersible oil suspension concentrate is prepared from 7.5 parts of pyrazosulfuron-ethyl, 4 parts of fenoxaprop-P-ethyl, 6 parts of penoxsulam, 5 parts of fatty alcohol-polyoxyethylene ether, 8 parts of styrylphenol polyoxyethylene ether, 2 parts of xanthan gum, 1 part of sodium benzoate, 2 parts of organic silicon and 64.5 parts of solvent oil by weight. The preparation method is characterized by pumping the raw materials into a preparation kettle, mixing and stirring the raw materials, then carrying out primary milling with a colloid mill, then finely milling with a sand mill, carrying out sampling analysis, and filtering, metering, packaging and warehousing after samples are qualified. The pyrazosulfuron-ethyl, fenoxaprop-P-ethyl and penoxsulam compound dispersible oil suspension concentrate achieves better control of annual grassy weeds, cyperaceous weeds and part of broadleaf weeds in the direct sowing paddy fields, and achieves united synergy of pyrazosulfuron-ethyl, fenoxaprop-P-ethyl and penoxsulam, thus achieving obvious synergistic effects; therefore mixing pyrazosulfuron-ethyl, fenoxaprop-P-ethyl and penoxsulam to control the weeds in the direct sowing paddy fields is feasible and is also necessary.

The invention provides a fluroxypyr-mepthyl, 2,4-D isooctyl ester and fluorasulam compound suspending agent, and relates to the technical field of wheat field weedicides. The suspending agent comprises, by weight, 0.5 part of florasulam, 12.5 parts of fluroxypyr-mepthyl, 37 parts of 2,4-D isooctyl ester, 3 parts of fatty alcohol-polyoxyethylene ether, 5 parts of styrylphenol polyoxyethylene ether, 0.5 part of xanthan gum, 0.3 part of sodium benzoate, 0.5 part of organic silicon and 40.7 parts of deionized water. All the raw materials are put into a preparation kettle, mixed and stirred, then are ground roughly through a colloid mill, ground fine through a sand mill, sampled and analyzed, and then are filtered, measured, packed and stored after being qualified. The compound suspending agent has a good control effect on broadleaf weeds such as clivers, flixweeds, starwort, polygonum weeds and asteraceae weeds in a wheat field, and can obviously improve the effects of the fluroxypyr-mepthyl, the 2,4-D isooctyl ester and the fluorasulam.
