The drug has a number of advantages over other similar agents. Its main feature is that the active substance is able to penetrate into plant cells through the root system and leaf plates.
After weed treatment, metribuzin penetrates the cell membranes, moving acropetally, that is, from the base to the top. As the substance progresses, inhibition of electrons occurs, which take an active influence in photosynthesis. A similar process leads to the gradual death of the weed. The aftereffect of Zenkora is possible up to 2 months from the date of processing. 
Despite the safety of the drug for humans, in order to avoid possible health problems due to individual intolerance, it is necessary to use protective equipment.
The effectiveness of the herbicide depends on a number of factors.:
- climate;
- ambient temperature;
- humidity of air and soil;
- type of soil.
In the process of processing, the agent creates a kind of protective film on the soil. It disappears during mechanical processing of the soil. This action is possible before germination.

At the same time, the potato tops themselves can be sprayed, since through it the herbicide affects the weeds. The consumption of funds depends on the composition of the soil.
Zenkor herbicide for tomatoes can be used for seed and seedlings. The first treatment is recommended in the pre-sowing period. It is important to apply a significant amount of the product to form a film on the soil.

The use of Zenkor on alfalfa is allowed after the second year of the growing season. The soil can be sprayed before the first crop emergence to create a protective film. The second treatment should follow when the alfalfa reaches 10-15 cm in height.
