Physcion

Emodin methyl ether is a highly active plant-based fungicide. It is extracted from natural plants such as rhubarb, and processed to obtain its active ingredients. It has excellent control effects on powdery mildew, downy mildew, gray mold, anthracnose, etc. It is low in toxicity to humans and animals and friendly to the environment, and is particularly suitable for green and organic vegetable production. Emodin methyl ether is a protective fungicide that induces the plant to produce defense responses, inhibits the germination of pathogen spores, the growth of hyphae, and the formation of appressoria, thereby protecting the plant from pathogen attack and achieving disease prevention effects.

Action mechanism: It belongs to plant-based pesticides and has systemic properties. It mainly inhibits the oxidation and dehydrogenation of sugars and sugar metabolism intermediate products of bacteria, and inhibits the synthesis of proteins and nucleic acids. It has good control effects on cucumber powdery mildew.

Natural anthraquinone compounds have the most significant inhibitory effect on pathogen development before the pathogen invades, that is, before the formation of appressoria protoplasts. The mechanism of action lies in significantly inhibiting the germination and attachment of spores of pathogenic fungi and the formation of appressoria protoplasts, causing most of the attachment protoplasts to be abnormal and unable to form appressoria protoplasts.

It not only inhibits the germination and growth of fungi, but also induces the plant to produce stress-resistant defense responses.

It has control effects on powdery mildew of most crops, and also has good control effects on downy mildew, gray mold, anthracnose, etc.

Emodin methyl ether has extremely low toxicity to humans and animals and is friendly to the environment. It is particularly suitable as a biological agent for green and organic vegetable production.

High activity and strong persistence

No cross-resistance with other chemical components

It should be sprayed before or in the early stage of disease occurrence. It can be sprayed 2-3 times continuously, with an interval of about 7 days. 2. It is recommended to use this product at the initial stage of powdery mildew. The application method is spraying. 3. The best time for spraying is in a windless or light wind condition without dew.
