Mechanism of drug action

Herbicide penetrates into weeds through leaves and roots. The active substance inhibits photosynthesis. The herbicide slowly decomposes in the soil, therefore it has a long protective effect, protecting crops from weeds throughout the growing season.

Plant growth stops immediately after the active substance gets inside. After 2-5 days, necrosis and chlorosis occurs. Weeds completely die in 2-3 weeks. Herbicide shows the highest activity on the initial growth of weeds.

Advantages and disadvantages of herbicide

Zontran Advantages:
