Bactericide composition aiming at plant bacteria and fungus diseases and application thereof

Abstract

The invention relates to the technical field of pesticides, and particularly relates to a bactericide composition which takes zhongshengrnycin and copper oxychloride as effective ingredients, has an obvious and enlarged bacteriocidal spectrum and no phytotoxicity, and is used for treating plant bacterial diseases as well as fungal diseases. The weight proportion of the zhongshengrnycin to the copper oxychloride is 1:5-60. The bactericide composition has obvious synergistic effect, high field prevention effect and a wide bacteriocidal spectrum, is used for preventing and treating cucumber bacterial angular leaf spot, cucumber downy mildew, tomato bacterial macula disease, tomato leaf mold, pumpkin soft rot, watermelon bacterial angular leaf spot, watermelon sponge, apple alternaria leaf spot, apple brown blotch, pear scabs, grape downy mildew, grape powdery mildew, anthracnose of grape, jujube rust diseases, jujube anthracnose, citrus canker, citrus scab, citrus anthracnose, peanut leaf spot diseases and peronophythora litchii, and has the advantages of good effect and reduction of prevention and treatment cost.

Description

technical field [0001] The invention relates to the technical field of agricultural fungicides, in particular to a fungicide composition for plant bacteria and fungal diseases, and also relates to the application of the fungicide composition. Background technique [0002] In agricultural production practice, plant bacterial diseases are becoming more and more serious, and plant bacterial diseases often occur in combination with fungal diseases. And the medicament kind for plant bacterial disease is few, and effect is poor. Some fungicides have strong selectivity so that the control spectrum is narrow, and farmers must use multiple fungicides together. The abuse of chemical fungicides has caused serious environmental pollution and food safety problems. The development of new fungicides is an important way to solve the above dilemma. [0003] Zhongshengmycin (zhongshengmycin) belongs to N-glycosides and is a broad-spectrum agricultural bactericidal antibiotic. It inhibits t...

Problems solved by technology

[0005] In order to solve the above problems that there are fewer types of compound preparations of Zhongshengmycin and copper preparations are prone to phytotoxicity, the present invention provides a kind of Zhongshengmycin A fungicide composition that mainly treats plant bacterial diseases and also treats fungal diseases with copper oxychloride as an active ingredient, significantly expanded bactericidal spectrum, and significantly reduced phytotoxicity
