Bactericidal composition containing benziothiazolinone and pyraoxystrobin and application

Abstract

The invention discloses a bactericidal composition containing benziothiazolinone and pyraoxystrobin. The bactericidal composition is prepared from active ingredients of benziothiazolinone and pyraoxystrobin and auxiliary ingredients, wherein the mass ratio of the benziothiazolinone to pyraoxystrobin is (1 to 80) to (1 to 80). The bactericidal composition can be used for preventing and controllinga plurality of bacterial and fungal diseases of fruit trees, vegetables and cereal crops, realizes an obvious synergistic effect, delays drug resistance of pathogenic bacteria, has long duration, reduces the frequency of drug administration as well as the dosage, and lowers the using cost. The bactericidal composition disclosed by the invention can be used for preventing and treating the diseasessuch as citrus canker, cucumber downy mildew, rice blast and wheat scab, and realizes a remarkable effect.

Description

technical field [0001] The invention relates to the field of agricultural disease prevention and control, in particular to a combined fungicide containing thiamethoxam and pyraclostrobin and its application. Background technique [0002] Benziothiazolinone is a heterocyclic fungicide developed by Shaanxi Xidahuate Technology Industry Co., Ltd. Molecular formula: C 7 h 5 NOS, chemical name: 1,2 benzisothiazolin-3-one. [0003] Thiemadone is a high-efficiency, low-toxicity, broad-spectrum fungicide, which can destroy the cell membrane protein and synthesis system of pathogenic bacteria, thereby inhibiting the reproduction of pathogenic bacteria, interfering with the metabolism of pathogenic bacterial cells, making them physiologically disordered, and leading to the death of pathogenic bacteria. The compound has good control effects on various crop diseases caused by bacteria and fungi, is very safe to crops and the environment, has low toxicity and no residue. [0004] Pyr...

AI Technical Summary

Problems solved by technology

Seedlings and saplings are particularly severely damaged, resulting in fallen leaves and dead shoots, which will affect the tree vigor; the severely damaged fruit will drop fruit, and the light one will have disease scars, which will not tolerate storage and rot, which will greatly reduce the commodity value of the fruit and increase the cost of disease and pest control for fruit farmers. , loss of economic benefits

At present, there is no report on the combined fungicides of thiamethoxam and pyraclostrobin to control cucumber downy mildew, rice blast, wheat head blight, and citrus canker
