Problems solved by technology

[0007] However, using a single fungicide alone cannot completely and effectively control the occurrence of cucumber powdery mildew. In the actual process of agricultural production, due to the current non-standard use of pesticides, the disease is becoming more and more resistant to pesticides, resulting in The use of pesticides is increasing year by year, so that the pollution of the environment is becoming more and more serious

Abstract

The invention relates to a bactericidal composition containing Pyridaclometyl and fluorophenyl ether amide, a preparation containing Pyridaclometyl and fluorophenyl ether amide and application thereof. The mass ratio of the effective components, namely Pyridaclometyl to the fluorophenyl ether amide, is (1-3): (5-1), and the mass percent of Pyridaclometyl and the fluorophenyl ether amide in the bactericidal composition / preparation is 20-80%, and the balance is auxiliary materials. The bactericidal composition / preparation shows an obvious synergistic effect on prevention and treatment of powderymildew of cucumbers. The sterilization composition and the preparation are suitable for preventing and treating powdery mildew of cucumbers and application in rice blast and banded sclerotial blight.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a bactericidal composition containing Pyridachlometyl and fluphenamide. Background technique [0002] Cucumber powdery mildew is one of the major diseases in current cucumber production. Cucumber powdery mildew, commonly known as "white hair disease", is the most serious damage to leaves, followed by petioles and stems. After powdery mildew infects petioles and tender stems, the symptoms are similar to those on leaves, with smaller disease spots and less powdery matter. Small yellow dots start to appear on the leaves, and then expand and develop into round or oval lesions with a white powdery mold layer on the surface. Generally, the lower leaves are more than the upper leaves, and the back of the leaves is more than the front. The mildew spots are scattered separately in the early stage, and then combined to form a large mildew spot, which can even cover the whole leaf, serio...
