Did you know? The herbicidal effect of ferrous sulfate was discovered in 1897, and in 1908 the American Argon Bolley published data on the use of sodium compounds and ferrous sulfate for the destruction of weeds on wheat crops.
The mechanism of action of the active substance
The effectiveness of the herb "Prima", the use of which allows you to eliminate up to 95% of weeds, provide two active substances with different principles of action:
- Florasulam - inhibits the synthesis of amino acids in weeds, the content - 6.25 g / l.
- Ether 2.4-D - quickly penetrates the leaves of weeds and blocks the activity of the hormone that regulates plant growth, 452.42 g / l.
Thus, the combined herbicide affects weeds that are sensitive to at least one of the active substances.
You can use herbicides to control weeds in your area: Agrokiller, Zenkor, Lazurit, Lontrel-300, Ground, Titus, Stomp.
Technology and instructions for use
Plants are sprayed with a solution of the concentrate with water. The optimal time for processing is spring, when plants have 2-8 true leaves. During this period, they are most sensitive to the components of the herbicide. 
Tips and tricks
- Before working with the Prima herbicide, carefully read and follow the instructions for use.
- Equipment for processing plants should be well regulated, adjusted to the average spray radius.
- The use of slotted nozzles is recommended.
- When you make a working solution, you need to take into account the weather forecast, within 24 hours before and after, there should be no frost.
- The optimum temperature for introduction is from +8 to + 25 ° С.
Important! If the recommended concentrations are exceeded, selective herbicides can destroy all vegetation in the area.
Consumption rates for different crops
The application rate of the drug per 1 hectare is 0.4-0.6 l. concentrate, depending on:
- crop density;
- stages of development and density of weeds;
- weather, temperature.
To prepare the solution for spraying, the concentrate is diluted with water. Solution consumption per 1 hectare - 150-400 liters. 
Grain, spring and winter crops, millet - crops that are processed at the tillering stage before the plants enter the tube or form 2 internodes in the initial phases of weed development. Consumption per 1 hectare:
- concentrate - 0.4-06 l;
- aqueous solution - 200-400 l.
- concentrate - 0.4-06,
- an aqueous solution - 200-400.
Important! The test for miscibility of the preparations is carried out before preparing the mixture, combining them in a small amount in a separate container.
Herbicide compatibility with other drugs
Herbicide "Prima" is compatible with most plant protection products:
- insecticides;
- nitrogen fertilizers (liquid);
- plant growth regulators;
- fungicides;
- other herbicides.

- feed and premix;
- seeds;
- food;
- pharmaceutical, medical and veterinary drugs;
- flammable substances and pyrotechnics.
The use of concentrate and working solution "Prima" allows you to quickly and efficiently get rid of weeds, to increase the yield and quality of the grown product. When using pesticides, it is necessary to follow the rules of safety, dosage and concentration of the drug, thus avoiding unnecessary costs and risks.
