Problems solved by technology

[0007] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge

Abstract

The invention discloses a bactericidal composition containing benthiavalicarb-isopropyl and carbendazim, and applications thereof. Benthiavalicarb-isopropyl and carbendazim are the main active components of the provided bactericidal composition, and the weight ratio of benthiavalicarb-isopropyl to carbendazim is 1-70:1-50. The invention also discloses an application of the bactericidal composition in the prevention and control of diseases of cereals, fruit trees, and vegetables. A high synergistic effect is generated. The drug resistance of pathogens is overcome and delayed. The bactericidal effect is quick. The bactericidal effect can last for a long time. The application cost is reduced. The control effect is obviously better than that of single component. The bactericidal composition can be used to prevent fungal diseases of crops, especially phytophthora root rot, late blight, downy mildew, powdery mildew, anthracnose, early blight, and the like, and the using effect of the bactericidal composition is better than that of single component.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition containing benthiazil and carbendazim and its application. Background technique [0002] Benthiavalicarb-isopropyl, molecular formula: C 18 h 24 FN 3 o 3 S, chemical name: [[(6-fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl]carbamate isopropyl ester. [0003] Benthiopyram has good bactericidal activity against Phytophthora, and it has a good inhibitory effect on the formation of sporangia and the germination of sporangia at low concentrations, but it has a good inhibitory effect on the release of zoospores and the movement of zoospores. No effect. In field trials, benthiazil was used at a lower dose (25-75g a.i. / hm 2 ) can effectively control late blight of potato and tomato, downy mildew of grape and other crops. [0004] Carbendazim (Carbendazim), molecular formula: C 9 h 9 N 3 o 2 , chemical name: N-(2-benzoimidazo...
