Embodiment 1

[0075] Embodiment 1: 51% thiamin lentinan microemulsion

[0076] Components: Methiamin 50%, Lentinan 1%, Non-ionic surfactant Nongru 600# 3%, Anionic surfactant Nongru 500# 3%, Xylene 1%, Methanol 5%, Water 100% %.

[0077] 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

[0078] Example 2: 31% formosan · lentinan water dispersible granules

[0079] Components: Methiamin 30%, Lentinan 1%, Sodium Alkyl Naphthalene Sulfonate 5%, Sodium Lignosulfonate 7%, Sodium Lauryl Sulfonate 2%, Ammonium Sulfate 5%, Kaolin Supplement .

[0080] 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 31% formosan·lentinan water-dispersible granules.

Embodiment 3

[0081] Example 3: 26% Methiamin · Lentinan Suspension Concentrate

[0082] Components: Methiamin 25%, Lentinan 1%, Sodium Naphthalene Sulfonate Formaldehyde Condensate 1%, Sodium Lignosulfonate 3%, Xanthan Gum 2%, Bentonite 1%, Glycerin 5% , make up to 100% with water.

[0083] Preparation method: Mix the components, mix them evenly by high-speed shearing, and then grind them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and then you can prepare 26% thiamin · shiitake mushrooms polysaccharide suspension.

Abstract

The invention provides a bactericidal composition and applications thereof, wherein the active components are methiadinil (A) and a saccharide compound (B), a weight ratio of (A) to (B) is 50:1-1:50,and the carbamate compound (B) is lentinan, amino oligosaccharin, chitosan, mushroom proteoglycan, glucosan or oligosaccharin. According to the present invention, by compounding the active componentssuch as methiadinil (A) and the saccharide compound (B), the significant synergistic effect can be provided, and the application amount of each single agent can be effectively reduced; the compositioncan be added to the acceptable auxiliary components of other pesticides so as to be processed into any one dosage form; and the bactericidal composition is mainly used for preventing and controllingdowny mildew, Phytophthora capsici, anthracnose, early blight, rice blast, wheat powdery mildew, banana leaf spot, virus diseases, bacterial angular leaf spot, soft rot and other fungal diseases and bacterial diseases.

Description

technical field [0001] The invention relates to a fungicide composition, in particular to a compound fungicide composition containing methiamide and carbohydrate compounds 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, redu...
