Problems solved by technology

However, many studies have shown that if these two agents are used alone to prevent and control diseases, they can make pathogenic bacteria resistant to them in a short period of time, resulting in reduced control effects and even failure of control.

Embodiment 1

[0036] Embodiment 1 (the preparation method of 60% Thiofuramide Chlorazurin wettable powder)

[0037] Raw material formula: by mass percentage

[0038]

[0039] Preparation method: uniformly mix the above-mentioned substances, and pulverize the mixture through a jet mill to obtain a wettable powder.

Embodiment 2

[0040] Embodiment 2 (the preparation method of 30% Thiofuramide Chlorazurin Suspending Concentrate)

[0041]

[0042] Preparation method: According to the formula, weigh each component in proportion, put it into a ball mill and mill it for 30 minutes, filter, pump it into the dispersion tank for 3 minutes, and then grind it fully with a sand mill to control the particle diameter of the solid component within 2 microns , and stir evenly after grinding to obtain a suspension product.

Embodiment 3

[0043] Embodiment 3 (preparation method of 40% thifuramide · cloxastrobin water-dispersible granule)

[0044]

[0045] Preparation method: mix thiofluxamide, chlorpyrexate, sodium methyl fatty acid amides benzene sulfonate, sodium carbonate, and attapulgite evenly, and then pulverize it with a jet mill to a particle size of 5 μm to obtain the mother powder. Fully mixed with sodium lignosulfonate, granulated, dried, and sieved to obtain water-dispersible granules.

Abstract

The invention discloses a bactericidal composition containing triclopyricarb and thifluzamide. The bactericidal composition consists of active components of triclopyricarb and thifluzamide in the mass ratio of 20:1-1:20, and the active components account for 5-60%. The bactericidal composition provided by the invention has high bactericidal activity, and delays the emergence and development of pathogen resistance, and reduces the dosage of prevention in actual production, and has the advantages of economical performance, high efficiency, safety and environment-friendliness. The bactericidal composition provided by the invention has good control effect on a variety of crop diseases, particularly significant control effect on rice sheath blight disease.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicidal composition containing chlorpyrastrobin and thifuramide and an application thereof. Background technique [0002] Rice sheath blight is a worldwide epidemic disease caused by Rhizoctonia solani, and it is also one of the most important diseases of rice in my country. Its distribution is very wide, and it occurs in all major rice producing areas in my country, especially in the middle and lower reaches of the Yangtze River and South China. The damage is very serious, resulting in a sharp decline in yield. Breeding and promoting disease-resistant varieties is one of the important measures to prevent and control rice sheath blight. In recent years, although scholars at home and abroad have made a lot of progress in disease-resistant breeding, there is still no one that is completely resistant to rice sheath blight. Immunized rice varieties. At present, the contr...
