Abstract

The invention belongs to the technical field of pesticides, and relates to a fungicidal and insecticidal composition containing lentinan. The fungicidal and insecticidal composition is characterized by comprising the following components in percentage by weight: 1 to 20 percent of fipronil and 0.1 to 2 percent of the lentinan. The fungicidal and insecticidal composition can be prepared into a suspending agent. The fungicidal and insecticidal composition provided by the invention improves the control effect of medicaments on plant virus diseases by controlling insects which are virus transmission media of the virus diseases and treating the virus diseases.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, in particular to a suspending agent with fipronil and lentinan as the basic formula, which is used as a plant fungicide. Background technique [0002] Lentinan not only has a strong inhibitory and killing effect, but also has obvious effects of disease resistance, yield increase and crop quality improvement. It is used to prevent and control viral diseases of rice, tomato, pepper, cucumber, tobacco, potato, flower and other crops. Lentinan has been used in the field of medicine for a long time. It has the effects of improving human immunity, anti-cancer, treating malignant tumors, and anti-virus, and has been widely proved in clinical practice. However, because of its complex production process and expensive products, it was not applied to the agricultural field until the late 1990s. Due to factors such as high raw material prices, complex production process, unstable active ingre...
