1.Introduction of Physcion:
The extraction source of Physcion is Rheum palmatum L. Is a terpenoid compound.
The component is a secondary metabolite of plants and has the function of controlling plant diseases.
Physcion 10%；13%；20%；40%；75%,95% 98%
Physcion is a highly active plant-derived fungicide. It is made from natural plant rhubarb and carefully extracted
from its active ingredients. It is very good for powdery mildew, downy mildew, gray mold, anthracnose, etc.
Control effect. It is low-toxic to humans and animals and environmentally friendly, especially suitable for green
and organic vegetable production. The emodin methyl ether is a protective fungicide, which induces a protective
response of the crop, inhibits the spore germination of the pathogenic bacteria, the growth of the hyphae, and the
formation of the sip, so that the crop is protected from the pathogen and the disease prevention effect is achieved.
* Inhibits the growth of fungi, and induces crops to produce an anti-retroviral response.
* It has excellent control effect on most crops of powdery mildew, and also has good control effect against downy
mildew, gray mold and anthracnose.
*Emodin has very low toxicity to humans and animals and is environmentally friendly. It is especially suitable for
biological preparations of green and organic vegetables.
* The results of indoor activity measurement and field efficacy test showed that it has good inhibition and control
effect on cucumber powdery mildew. Spraying at the beginning of the onset of powdery mildew, the dilution factor
is 1000 times, foliar spray, the number of application depends on the condition, usually 2~3 times, interval 7-10 days.
*Good compatibility with other pesticides
* For the safety of crops within the dosage range, no phytotoxicity was produced.
* When using in the field, it is necessary to avoid the flowering period of silkworm area and honey plant, protect birds
and avoid pollution to waters. It is forbidden to clean application equipment in rivers and other waters.
