Physcion Uses

Compared with chemical pesticides, physcion has low risk of drug resistance, high activity, low dosage, good and stable disease prevention effect, and broad bactericidal spectrum. More than 10 important pathogenic bacteria such as bacteria and anthracnose have bactericidal activity, which is an ideal substitute for chemical fungicides, especially suitable for green and organic vegetable production.

The stability control of botanical pesticides is currently a recognized problem in the world. Due to the instability of natural substances, botanical pesticides are easily decomposed and fail in sunlight and high temperature, which has become a limiting factor for the development of botanical pesticides. The rhubarb extract can obtain a very stable control effect no matter under the acid-base condition or under the extreme temperature (-20~80℃). In particular, the 0.5% physcion aqueous preparation has good stability to the light and temperature conditions in the growing period of cucumber, which solves the disadvantage of unstable field application of plant pesticides. Due to the good stability of emodin methyl ether, it will have great development prospects in botanical pesticides.
