Problems solved by technology

[0004] However, in agricultural production activities, the long-term use of a single bacteriostatic agent is likely to cause the risk of drug resistance, resulting in unsatisfactory drug efficacy. In order to improve the bactericidal effect, farmers often increase the dosage to ensure the efficacy, but increasing the dosage not only increases the cost of pesticide use Also increases the environmental self-degradation load

preparation example Construction

[0031] The preparation method of the suspending agent of the present invention is not particularly limited, and the technical solution for the preparation of the suspending agent well-known to those skilled in the art can be adopted. In the present invention, the preparation method of the suspending agent preferably combines the The finished product is obtained by mixing and grinding mycotylin, copper quinoline, emulsifier, antifreeze, thickener and water.

[0032] In the present invention, the particle size of the ground product is preferably below 5 μm.

[0033] In the present invention, when the dosage form of the fungicidal composition is a water-dispersible granule, the water-dispersible granule preferably includes the following components in mass percentages: 1% to 28% of thiamethoxam, 1% to 28% of copper quinolate %~48%, wetting and dispersing agent 1%~4%, emulsifier 3%~6%, disintegrant 2%~6%, filler white carbon black 15%~25%, starch to 100%; more preferably It is a c...

Embodiment 1

[0052] Weigh 5g of thiamethoxam, 45g of copper quinoline, 6g of wetting and dispersing agent sodium lignosulfonate, 2g of sodium lauryl sulfate, 3g of pull-off powder BX, 5g of filler white carbon black, and make up to 100g of kaolin. After the material is fully mixed and uniform, it is crushed by airflow to a fineness of 500 mesh, and a 50% thiamethadin·copper quinoline wettable powder is obtained.

Embodiment 2

[0054] Weigh 1g of thiamethoxam, 48g of copper quinoline, 4g of wetting and dispersing agent sodium lignosulfonate, 3g of sodium lauryl sulfate, 4g of pull-off powder BX, 3g of filler white carbon black, and make up to 100g of kaolin. After the material is fully mixed and uniform, it is crushed to a fineness of 800 mesh by air flow, and 49% thiamethoxamyl quinoline copper wettable powder is obtained.

Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises benziothiazolinone and copper quinolate at a weight ratio of (80-1):(1-80). When the weight ratio of benziothiazolinone to copper quinolate is in a range of (80-1):(1-80), toxicity index level cotoxicity coefficient (CTC), calculated by the SunYunpei method, of the bactericidal composition is less than 100, and it is explained that coordinated application of benziothiazolinone and copper quinolate exerts obvious synergistic effects; compared with bactericides prepared by the independent use of benziothiazolinone or copper quinolate, the bactericidal efficacy of the bactericidal composition is greatly improved, and the use amount and the negative effects on the environment are reduced.

Description

technical field [0001] The invention relates to the technical field of biopesticide fungicides, in particular to a fungicidal composition containing thiamethoxamin and copper quinolate. Background technique [0002] At present, in domestic agricultural production activities, crop root or stem diseases caused by fungi, bacteria, nematodes and viruses are becoming more and more serious. In addition, long-term land continuous cropping, multiple cropping and unscientific fertilizer application have aggravated the occurrence of diseases, such as damping-off Disease, root rot, blight, etc. can easily cause seedling death, lack of rows and broken ridges, and even cause seedlings to fall and die in pieces. [0003] Quinoline copper (oxine-copper) is a quinoline-type low-toxic protective fungicide. After spraying, a tight protective film is formed on the surface of the plant. The slowly released copper ions inhibit the germination and invasion of germs, thereby achieving anti-corrosi...
