Embodiment 1

[0032] Preparation of 30% wettable powder of indazole sulfasulfame tebuconazole

[0033]

[0034] The various ingredients are mixed together, and the product is obtained by jet milling and passing through a 325-mesh sieve.

[0035] Preparation of 60% indazole sulfamethoxazole wettable powder

[0036]

[0037]

[0038] The various ingredients are mixed together, and the product is obtained by jet milling and passing through a 325-mesh sieve.

Embodiment 2

[0040] Preparation of 60% Indazolesulphamide Tebuconazole Suspension Concentrate

[0041]

[0042] The various ingredients are mixed together and ground in a sand mill until the particle size of the active ingredient is less than 4 μm. The addition of sodium lignosulfonate, JFC, and Nongru 600# is helpful to the preparation of the dosage form, can maintain the stability of the dosage form, is helpful for storage and transportation, and ensures the efficacy of the drug.

[0043] Preparation of 25% Indazolesulprofesmin Meconazole Suspension Concentrate

[0044]

[0045]

[0046] The various ingredients are mixed together and ground in a sand mill until the particle size of the active ingredient is less than 4 μm. The addition of sodium lignosulfonate, JFC, and Nongru 600# is helpful to the preparation of the dosage form, can maintain the stability of the dosage form, is helpful for storage and transportation, and ensures the efficacy of the drug.

Embodiment 3

[0048] Preparation of 20% tebuconazole · indazole sulfasulfame microemulsion

[0049]

[0050] After the indazole sulfasulfame and tebuconazole are completely dissolved, add an emulsifier and stir evenly to form an oil phase, and finally add water and stir to form a uniform transparent homogeneous liquid.

Abstract

The invention provides a pesticide composition capable of preventing and controlling plant diseases and particularly relates to a pesticide active composition which consists of amisulbrom or crystals thereof and one or more of tebuconazole, fenbuconazole, metconazole, tetraconazole, triticonazole, bromuconazole, fluquinconazole and myclobutanil in a compounding way, wherein the mass ratio of amisulbrom to other active substances is 1:9 to 9:1 and the weight percentage of effective components is 1-90 percent. The pesticide composition can prevent and control virus diseases, downy mildew, gray mold, droop, anthracnose, epidemic diseases, blight, pythium rot, verticillium wilt, stalk break, powdery mildew, rust diseases and gibberellic diseases.

Description

technical field [0001] The invention relates to the field of compound pesticide compositions, in particular to a synergistically effective pesticide active composition. Background technique [0002] In recent years, the large-scale outbreaks of fungal diseases of food crops, commercial crops and vegetables in China, as well as the lack of effective antibacterial agents have led to the occurrence of fungal diseases and the trend of the spread of "China-Southeast Asia-East Asia" global pattern of fungal diseases, making Agricultural fungus has become the bottleneck and obstacle affecting the normal and orderly development of my country's agriculture and the world's agriculture. How to quickly and effectively obtain high-efficiency and low-cost green antibacterial pesticides has become the focus of current agricultural science. Plant diseases caused by downy mildew, gray mold, fusarium wilt, anthracnose, blight, blight, cotton rot, verticillium wilt, sclerotinia, powdery mildew,...
