Abstract

The invention discloses a fungicidal pesticide composition containing benzothiostrobin and mandipropamid. The fungicidal pesticide composition comprises effective components, namely the benzothiostrobin and the mandipropamid, and common auxiliary components; the weight ratio of the benzothiostrobin to the mandipropamid ranges from (1 to 45) to (45 to 1). A lot of indoor and outdoor experiments show that the fungicidal pesticide composition provided by the invention has remarkable synergistic interaction effects on a plurality of diseases which are harmful to growth of crops, especially cucumber downy mildew and powdery mildew; the aims of reducing the drug dosage and increasing the prevention and control effects can be realized and the fungicidal pesticide composition is worthy of being popularized and applied in production.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to a fungicidal pesticide composition of penthiostrobin and mandiprod and its application. Background technique [0002] The single use of pesticides and other unscientific use methods are prone to risk of resistance and increased dosage. For example, early blight pathogens, late blight pathogens, downy mildew, etc. have developed resistance to some commonly used agents, thereby increasing the cost of medication and Environmental issues. The emergence of bacterial resistance leads to a decline in control efficiency and rampant disease, which in turn leads to frequent application of pesticides, resulting in increased cost of medication and aggravated environmental pollution. According to the different action mechanisms of drugs, using pesticide compounding to screen out compositions with significant synergistic effects is a common method to delay the development of ...
