Embodiment 1

[0028] The preparation method of 55% azoxystrobin Jinggangmycin wettable powder: by mass percentage.

[0029] Azoxystrobin 50%;

[0030] Jinggangmycin 5%;

[0031] Sodium dodecylbenzenesulfonate 2%

[0032] Sodium lignosulfonate 4%;

[0033] Silica 10%;

[0034] Kaolin balance / 2;

[0035] Attapulgite balance / 2

[0036] Preparation method: Add the above components into a mixer according to the formula ratio, mix them evenly, and then carry out airflow crushing. After the crushing is completed, stir well and evenly to get a wettable powder product. The amount of preparation per mu is 40-60g, and the effect of controlling rice sheath blight can reach more than 85%.

Embodiment 2

[0038] The preparation method of 32% azoxystrobin Jinggangmycin suspension concentrate: by mass percentage.

[0039] Azoxystrobin 30%;

[0040] Jinggangmycin 2%;

[0041] Sodium Methylenebismethylnaphthalene Sulfonate 5%;

[0042] Castor oil ethoxylate 3%;

[0043] Xanthan gum 0.15%;

[0044] Tributyl phosphate 0.3%;

[0045] Propylene Glycol 5%;

[0046] water balance.

[0047] Preparation method: According to the formula, weigh the above components in proportion, add to a ball mill and mill for 30 minutes, filter Jinggangmycin after fully dissolving, pump into a dispersion tank for 3 minutes at high speed and then fully grind with a sand mill to control the solid components The particle diameter is within 2 microns, and after grinding, stir evenly to obtain a suspension product. The amount of preparation per mu is 50-70g, and the effect of controlling rice sheath blight can reach more than 85%.

Embodiment 3

[0049] The preparation method of 30% azoxystrobin Jinggangmycin suspension concentrate: by mass percentage.

[0050] Azoxystrobin 25%;

[0051] Jinggangmycin 5%;

[0052] Sodium lignosulfonate 5%;

[0053] Alkylphenol-ethylene oxide condensate 3%;

[0054] Sodium alginate 0.2%;

[0055] Tributyl phosphate 0.3%;

[0056] Urea 6%

[0057] water balance.

[0058] Preparation method: with embodiment 2. 50-70g per mu is used to control rice sheath blight and the effect can reach more than 85%.

Abstract

The invention discloses a sterilization composition containing mepanipyrim and validamycin, wherein a mass ratio of the mepanipyrim and the validamycin is 20:1-1:20. The sterilization composition containing the mepanipyrim and the validamycin has a good control effect against crop fungous diseases such as a rice sheath blight disease. Due to the fact that the mepanipyrim and the validamycin are matched in application, a dosage can be reduced. Due to the fact that the validamycin is a biopesticide, when the sterilization composition containing the mepanipyrim and the validamycin is in use, ecological damage and environmental pollution can be effectively reduced, and output and quality of crops can be improved. Due to the fact that the mepanipyrim and the validamycin are both low in toxicity, the sterilization composition containing the mepanipyrim and the validamycin is safe to people, livestock and beneficial organisms, and can delay drug resistance of germs to a single agent.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and in particular relates to a fungicidal composition of azoxystrobin and Jinggangmycin. Background technique [0002] Mepanipyrim (English common name: mepanipyrim), molecular formula is C 14 h 13 N 3 , the structural formula is as follows: [0003] [0004] The general chemical name is N-(4-methyl-6-prop-1-ynylpyrimidin-2-yl)aniline, which is a new type of pyrimidine amine fungicide, and its mechanism of action inhibits the secretion of cell wall decomposing enzymes produced by pathogenic bacteria to the outside of the bacteria At the same time, it inhibits the absorption of nutrient sources such as amino acids and glucose by the bacteria, thereby preventing pathogenic bacteria from invading plants. It can be used to control crop diseases caused by various fungal pathogens. [0005] Jinggangmycin (English common name: Validamycin), the molecular formula is C20H35O13N, and the stru...
