Timely protection of crops from weeds helps increase yields and simplifies garden maintenance. Prometrin provides a long-lasting protective effect. Its advantages include low cost, ease of use when diluting the working solution, and control of a wide range of grasses and annual broadleaf weeds.
What is included in the composition and existing forms of release
Prometrin is a systemic soil-applied herbicide. Its distinctive feature is its long-lasting protective effect. It is used to control broadleaf and grass weeds in various cultivated crops and is available as a suspension concentrate.
When purchasing this product, keep in mind that promethrin (deltamethrin) is sold in ampoules—an insecticidal acaricide for killing ticks, flies, and other pests. For weed control, manufacturers offer Promethrin and various promethrin-based herbicides packaged in 5- and 10-liter plastic canisters.
Purpose and principle of operation
Penetrating through foliage and roots, the product spreads to plant seedlings and inhibits photosynthesis. It is applied before sowing or directly during sowing. The herbicide's effects are visible within 2-4 days after weed emergence. Complete weed control occurs within a week or a week and a half.
By spraying, it is possible to clear the area of white goosefoot, field mustard, black nightshade, barnyard grass, common vetch, medicinal fumitory, spreading and garden orach, chickweed, shepherd's purse, garden purslane, field violet, stinging nettle, yellow fulvous, common datura, common ragweed, field cabbage, wild radish, field and white mustard.
Prometryn is most effective when the soil is moist. If the soil is dry, it is not recommended to sow winter cereals or perennial grasses in the treated area in the fall.

Instructions for use
To ensure the effectiveness of the herbicide, it is recommended to follow the manufacturer's instructions for consumption rates and application rules.
| Processing object | Consumption rates | Type of weed | Features of application |
| Carrot | 1.50 | annual cereals and dicotyledons | cultivate the soil before sowing/before the crop emerges |
| Potato | 2.0-3.5 | spray the soil before the crop germinates | |
| Sunflower | 2.0-3.5 | simultaneously with sowing or before the emergence of crop shoots | |
| Corn for grain | 2.0-3.5 | simultaneously with sowing or before the emergence of crop shoots | |
| Soybeans | 2.5-3.5 | spray the soil before the crop germinates |
Safety precautions
The herbicide "Prometrin" is considered to be of low toxicity to humans. However, when spraying the area, safety precautions must be observed:
- During the processing, personal protective equipment (respirator, safety glasses, special clothing, rubber shoes and gloves) is used;
- During work, it is prohibited to drink, smoke, eat, or remove protective equipment;
- The treatment is carried out in calm, dry weather.
The working solution does not cause irritation when in contact with the skin. However, it is important to protect mucous membranes and the nasopharynx from contact with the herbicide. Symptoms of poisoning include drowsiness, a sore throat, and an unpleasant taste.
In case of poisoning, it is recommended to seek medical attention.
Is compatibility possible?
Prometryn can be used in tank mixes with most herbicides used to protect similar cultivated plants. However, prior testing of the mixtures is recommended.
How and how long can it be stored?
The concentrate has a shelf life of 3 years from the date of manufacture. It is recommended to store the herbicide in its original packaging in a dry, ventilated room. Do not use the room for storing the herbicide, food products, feed, or animal feed simultaneously.
What to replace it with
Prometryn is the active ingredient in many herbicides. Several popular products are available.
- Promenade is effective in destroying annual broadleaf and grass weeds. It also protects potato, carrot, and corn crops.
- The advantage of the herbicide "Gezagard" is its ability to destroy some difficult-to-eradicate weeds. The product completely decomposes in the soil during the growing season.
Prometrin is considered one of the best herbicides for protecting potato crops. Its protective period lasts 2.5-3 months (weather conditions must be taken into account). The product does not accumulate in the soil, so there are no restrictions on crop rotation plans.
