The drug "Topsin-M" is a fungicide that affects plants due to the contact-systemic effect on the source of infection. The tool can be used for the prevention and control of fungal diseases attacking cultivated plants, as well as for the destruction of harmful insects: leaf beetles and aphids.

Purpose and mechanism of action
Topsin-M has a protective and therapeutic effect on plants. Due to the main active substance phytopathogenic fungi are destroyed, the defeat of the root system is slowed down, the culture is improved.

"Topsin-M" is also used to combat diseases of indoor plants: orchids, dracaena, azaleas, streptocarpus, cyclamen.
The penetration of the fungicide into the plant occurs along the root system. At that moment, when the active substance gets to the source of infection, the growth of mycelium is blocked, and spores cannot germinate. The active ingredient gradually disperses throughout the plant, thereby providing a therapeutic effect on the affected organs and tissues of the culture.
Did you know? The permissible daily dose of thiophanate methyl for humans is 0.02 mg / kg. This is an insignificant concentration that does not affect the health.Thiophanate-methyl has an insecticidal effect, which can cause toxic reactions in various insects and pests.
