Mechanism of action
The main principle of impact "Healer" on plants of any type - contact system. 
Metalaxyl, one of the main active ingredients of this product, is absorbed by your culture at a sufficiently high rate and is evenly distributed throughout its structure, thus forming a reliable barrier for various pathogens of fungal diseases, regardless of the intensity of the infection process.
This substance inhibits the development of mycelium inside the plant, has a pronounced post-contagious activity and inhibits the formation of spores.
The second of the substances - mancozeb - is a contact action fungicide, which is aimed at the formation of external protection against pathogens by forming some similarity of "protective film". In addition, the presence in the tool of this component prevents the possible occurrence of tolerance to the action of the fungicide in disease-causing organisms.
Method of application and consumption rates
