Composition and release form of the herbicide
Metribuzin belongs to the triazinone class and is the active ingredient in herbicides.Available in the form of water-dispersible granules, concentrated suspension and wettable powder.

Spectrum and mechanism of action of the product
"Metribuzin" is used to destroy 1-year-old 2-lobed weeds and the cereal family in areas with tomatoes, potatoes, 2nd season alfalfa, soybeans and echinacea, and essential oil rose. The substance works as a photosynthesis inhibitor and is absorbed by leaves and roots. Decomposes in soil in 1-3 months.
Instructions for use of the drug "Metribuzin"
On tomatoes, Metribuzin is used on young plants at the 2-4 leaf stage; in potato plots, the soil is sprayed until germination. The consumption of the solution depends on the soil characteristics and the time when the treatment occurs. On light soils with a small fertile layer, the norm is lower than on fertile or clay soils. It is recommended to take the largest volume when spraying the soil, and the minimum when spraying tomato seedlings.
On alfalfa, treatment is done in the spring, before the plants begin to grow, or when the plants reach a height of 10-15 cm. On roses, the soil in the rows is sprayed before the growing season begins. Effective period: 6-8 weeks, the period varies depending on the type of soil, its level of heating and humidity. The herbicide "Metribuzin" does not cause phytotoxicity in many popular potato varieties. The destruction of weeds in the early stages ensures that crops receive nutrients, light and water in full.
Safety precautions
"Metribuzin" belongs to drugs with class 4 toxicity for humans and bees, that is, slightly toxic. Products with this toxicity class almost do not cause poisoning or irritation, but you still need to work with them using safety glasses, gloves and a respirator.

After work, you need to wash your hands and face with soap and water and rinse the sprayer.
