Compounded botanical synergistic fungicide containing sophocarpidine and osthol and preparation method of compounded botanical synergistic fungicide

Abstract

The invention discloses a compounded botanical synergistic fungicide containing sophocarpidine and osthol. The obtained compounded botanical synergistic fungicide takes sophocarpidine and osthol as main components, and is added with accessory ingredients in a synergistic manner; the morphology of the compounded botanical synergistic fungicide is environment-friendly missible oil, microemulsion, aqueous solution or soluble liquid; and in addition, the compounded botanical synergistic fungicide contains sophocarpidine accounting for 0.1 to 20 percent and osthol accounting for 0.1 to 20 percent, and the rest is the accessory ingredients. The compounded botanical synergistic fungicide is mainly used for controlling downy mildew, gray mold, anthracnose, powdery mildew, cladosporium cucumerinum, soft rot and basal stem rot. The compounded botanical synergistic fungicide does not contain any chemical pesticide component, is easy to degrade in environment, has no consideration of environment pollution and residual hazard, is safe to human, livestock and environment; germs are not easy to be drug-resistant to the compounded botanical synergistic fungicide; the compounded botanical synergistic fungicide is of great value to be applied and popularized on main agricultural and sideline products that earn foreign exchange through exports, such as melons, fruits, vegetables, tea leaves and medicinal materials; and in addition, the compounded botanical synergistic fungicide is an ideal novel pollution-free bactericide.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and specifically relates to a synergistic fungicide with matrine and osthole as active components and a preparation method thereof, which is mainly used in the prevention and treatment of melons, fruits, vegetables and tea trees Downy mildew, gray mold, anthracnose, powdery mildew, scab, soft rot, stem rot and other agricultural diseases. Background technique

[0002] Downy mildew, gray mold, anthracnose, powdery mildew, scab, soft rot, stem rot, etc. are the main diseases on melons, fruits and vegetables, with a wide range of damage and great difficulty in prevention and control. At present, the medicaments used to prevent and control these diseases are mainly chemical fungicides. However, the long-term use of a large number of chemical drugs has led to the emergence of problems such as drug resistance, environmental pollution, and harm to human health; The use of many chemical pesticides ha...
