The medicine is a systemic contact antifungal agent.
Sold in specialized stores in small bags with a capacity of twenty-five grams. But you can also find other packaging - bags of one and five kilograms.

Mechanism of action
Do not allow the solution to flow down the treated surface.
The mechanism of action of the drug consists of penetration into the crop, creating a barrier to the penetration of fungal spores throughout the entire area of the plant - from the root system to the fruits and tendrils.
A kind of protective film is formed on the surface of the entire green part of the bush. At the same time, the active ingredients gradually create a stable, but very short-term immunity to the fungus.
Properties
The drug Ridomil Gold is a therapeutic and prophylactic agent.

Components
The active components in the drug help cure the plant.
- M ancozeb is Chemical substance , belonging to the dithiocarbamate class. The mechanism of action is contact with the top layer of the plant.
- Metalaxyl is a phenylamide agent, affecting the “insides” of the bush. Penetrates into the tissues of the trunk, branches, leaves, shoots.
Features of the medicine
