INTRODUCTION
Physcion (CAS NO. 521-61-9, Chemical formula: C16H12O5) is synthetized from the emodin extracted from the root of Polygonum cuspidatum Sieb.et Zucc and the The root and rhizome of Rheum palmatum L．
Physcion (CAS NO. 521-61-9, Chemical formula: C16H12O5) is also known as Parietin, Physcion (CAS NO. 521-61-9, Chemical formula: C16H12O5) has also shown anti-fungal activity against barley powdery mildew and cucumber powdery mildew, more efficiently in the latter case than treatments with fenarimol and polyoxin B.
It has good systemic conduction effect, inhibits the formation of fungal hyphae, haustoria and spores by interfering with the biosynthesis of chitin in the cell wall of pathogenic fungi, thereby blocking the spread of diseases. It not only inhibits the germination and growth of fungi, but also induces stress-resistant defense responses in crops. It has a preventive effect on powdery mildew of most crops, and also has a good control effect on downy mildew, gray mold, anthracnose, etc.
APPLICATION
Physcion (CAS NO. 521-61-9, Chemical formula: C16H12O5) – A high activity fungicide of botanical resource. The Physcion has a very strong inhibition on about 26kinds of the bacteria, such as staphylococcus aureus，Escherichia Coli，Pseudomonas aeruginosa，streptococcus and shigella dysenteriae etc.
In agriculture, the Physcion (CAS NO. 521-61-9, Chemical formula: C16H12O5) is used as fungicide to control Powdery mildew, Downy Mildew, anthracnose and gray mold etc. Disease of Fungi.
