Problems solved by technology

The disease mainly harms wheat, not only affecting the yield of wheat, but also causing spoilage and deterioration of wheat grains. The toxins secreted by the disease bacteria can also poison humans and animals. In normal years, the yield can be reduced by 10-20%, and in pandemic years, the yield can be reduced by 50-60%, or even no harvest. serious threat to wheat production

Embodiment 1

[0019] Example 1: 55% metconazole·oligosaccharide water dispersible granules

[0020] 5g metconazole, 50g oligosaccharides, 4g sodium lauryl sulfate, 2g laureth, 2g lignin sulfonate, 2g sulfonic acid polyformaldehyde condensate (NNO), 2g polyethylene glycol , 4g ammonium sulfate, 10g sodium carboxymethyl cellulose, and kaolin make up to 100g to prepare 55% metconazole·oligosaccharide water dispersible granules.

Embodiment 2

[0021] Example 2: 55% metconazole·oligosaccharide water dispersible granules

[0022] 50g metconazole, 5g oligosaccharides, 4g sodium lauryl sulfate, 2g laureth, 2g lignosulfonate, 2g sulfonic acid polyformaldehyde condensate (NNO), 2g polyethylene glycol , 4g ammonium sulfate, 10g sodium carboxymethyl cellulose, and kaolin make up to 100g to prepare 55% metconazole·oligosaccharide water dispersible granules.

[0023] According to the formulas of Examples 1 and 2, the active ingredients, additives, and fillers were mixed, stirred evenly, and then pulverized to obtain a master powder. The master powder and the binder sodium carboxymethyl cellulose were mixed uniformly, and then granulated, After drying and sieving, metconazole·oligosaccharide water dispersible granules can be prepared.

Embodiment 3

[0024] Example 3: 50% metconazole·oligosaccharin wettable powder

[0025] 25g metconazole, 25g oligosaccharin, 4g sodium lauryl sulfate, 4g sodium lignin sulfonate, 2g open powder (BX), diatomaceous earth make up 100g. The 50% metconazole·oligosaccharin wettable powder was prepared.

Abstract

The invention discloses a sterilizing agent containing metconazole and oligosaccharide. The effective ingredients of the sterilizing agent are metconazole and oligosaccharide, the weight ratio of the metconazole to the oligosaccharide is (1:10) to (10:1). The invention further discloses application of the sterilizing agent to the prevention and curing of wheat scab. Practical tests show that the sterilizing agent provided by the invention has a remarkable effect of preventing and curing the wheat scab.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a fungicide containing metconazole and oligosaccharides and its application. Background technique [0002] Wheat head blight, also known as red-headed malaria and rotten wheat-head, occurs in all wheat regions across the country, with the most severe occurrence in the middle and lower reaches of the Yangtze River and spring wheat regions in the northeast. The disease mainly harms wheat. It not only affects wheat yield, but also causes wheat grains to spoil and deteriorate. The toxins secreted by the pathogen can also poison humans and animals. In general, the production can be reduced by 1-20%, and in pandemic years, it can be reduced by 5-6%, or even no harvest. A serious threat to wheat production. [0003] Head blight mainly damages the ears, but it can be damaged at all stages of wheat growth. Infection at the seedling stage causes seedling rot, and mid-late infection...
