Embodiment 1

[0064] Embodiment 1: 30.03% thiamin · humic acid microemulsion

[0065] Components: Methiamin 30%, humic acid 0.03%, non-ionic active agent Nongru 600#3%, anionic surfactant Nongru500#3%, xylene 1%, methanol 5%, water supplement 100%.

[0066] Preparation method: Mix the emulsifier and the original pesticide to form a solution, then add other solvents, drop into water under high-speed stirring, and form a transparent o / w microemulsion.

Embodiment 2

[0070] Embodiment 2: 25.05% methiamine · humic acid water dispersible granules

[0071] Components: Methiamin 25%, Humic Acid 0.05%, Sodium Alkyl Naphthalene Sulfonate 5%, Sodium Lignosulfonate 7%, Sodium Lauryl Sulfonate 2%, Ammonium Sulfate 5%, Kaolin Sulfonate Remain.

[0072] Preparation method: Mix the components uniformly to obtain a mixture, the mixture is mechanically pulverized and then jet-pulverized to obtain a secondary mixture, add water with 10%-15% of the mass of the secondary mixture to the secondary mixture, mix uniformly, and then pass through Extrude and granulate to form columnar or spherical granules, and finally dry to obtain 25.05% thiamin·humic acid water-dispersible granules.

Embodiment 3

[0076] Embodiment 3: 25.25% Methiamin Humic Acid Suspension Concentrate

[0077] Components: Methiamin 25%, Humic Acid 0.25%, Sodium Methyl Naphthalene Sulfonate Formaldehyde Condensate 1%, Sodium Lignosulfonate 3%, Xanthan Gum 2%, Bentonite 1%, Glycerol 5 %, make up to 100% with water.

[0078] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and you can prepare 25.25% thiamin. Glycolic acid suspension.

Abstract

The invention provides a bactericidal composition and applications thereof, and belongs to the field of combination of pesticides. The effective components of the bactericidal composition are methiadinil (A) and biostimulant (B), and the weight ratio of (A) to (B) is 10 : 0.01 - 0.01 : 10; the biostimulant (B) is humic acid, a seaweed extract product, an alternaria tenuissima activator protein orbeta-lupin globulin polypeptide; the compounding of the effective component (A) and (B) has obvious synergism, so that the application amount of each single dosage can be effectively reduced. The composition can add auxiliary components that are allowed to use in other pesticides and be processed into any dosage form; the composition is used for enhancing the autoimmune abilities of plants, so that the prevention of viral diseases, fungal and bacterial pathogens can be achieved; and the composition is mainly used for preventing fungal and bacterial diseases such as downy mildew, phytophthora,anthrax, early blight, rice blast, wheat powdery mildew, leaf spots of banana, viral diseases, bacterial angular spot diseases and soft rot diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericide composition containing methiamide and biostimulant and its application. Background technique [0002] Pesticides have played a huge role in increasing agricultural production and ensuring income with the characteristics of fast, effective and low price. However, unscientific and single use of pesticides have led to the continuous enhancement of bacterial resistance and the continuous increase of pathogenic varieties. At the same time, frequent use of pesticides is also It increases the economic burden, and leads to a series of serious ecological and social problems of environmental pollution and agricultural product safety. With the continuous improvement of people's living standards, the concern for environmental protection and the safety and quality of agricultural products have put forward higher requirements. Therefore, how to use scientifically, reduce th...
