The combined action substance contains the following components:

• florasulam;
• ether 2.4 D.

The chemical can be of two types. This is the herbicide "Prima Forte" - a water-soluble emulsion that is used to remove all types of weeds

• has a wide range of effects on weeds;
• effective against all types of weeds, including chamomile and thistle;
• long-term result;
• can be used at all stages of weed development;
• the result is noticeable immediately after application;
• the components quickly disintegrate in the soil and do not cause problems during subsequent sowing of grain crops;
• Can be used during rain.

Among the disadvantages, it is necessary to note the toxicity of the substance to the human body. If the instructions for preparing the solution are not followed, it may affect grain plants.

Mechanism of action of weed killer

After spraying, the components begin to interact and penetrate the plant, blocking the process of cell division and oxygen absorption. The active components disperse throughout the plant, blocking its growth and leading to death at the root level.

Consumption rates for various plants

When preparing the working solution, the consumption rate will depend on the spraying method. When spraying manually, the norm will be 500 liters of working solution. The use of machine spraying reduces the consumption rate to 300 liters of the working mixture.The use of aircraft implies a consumption of up to 200 liters per 1 hectare. Also, the consumption rate will depend on the type of crop, the average consumption is 0.5 emulsion per 1 ha.

Preparation of working solution

To prepare the working mixture for spraying, you need to shake the substance, as there may be sediment at the bottom. The emulsion is mixed in a proportion of 5 liters of chemical with 15 liters of water. The resulting solution is poured into the spray tank and the land is treated.

Important. After opening the package with the drug, you must immediately prepare the solution and use it for its intended purpose. Working fluid is not stored.

Instructions for use

The substance is used in the morning or evening. A continuous processing method is carried out. The period of use is when the weed is at the formation stage. However, the substance eliminates even adult plants. When using a post-sowing substance, treatment is carried out after the formation of the 5th leaf on the grain crop.

After preparation, the solution is sprayed. The result will be noticeable within a day after treatment. The drug is used once a season, but if necessary, the treatment process can be repeated after 14 days.

Precautions for use

When spraying, special protective clothing must be used. Special glasses and a respirator are also used. After treatment, the person should take a shower with soap.

Do not use the substance near open fire, children and pets. Also, the drug is not recommended for use at the time of pollination of the crop, as this can harm pollinating insects.

Herbicide "Prima" can be used in combination with other chemicals. When using analogues, this criterion must be clarified. Each of the analogues may have specific uses depending on the type of crop.

Bottom line

The use of the Prima herbicide keeps the land clean and reduces the risk of diseases on grain crops. A properly prepared working solution does not affect crop growth and allows you to eliminate all types of weeds in a short time. During spraying, it is necessary to hide all areas of the body, since the substance can cause irritation and burns upon contact with skin.
