Instructions for use of the herbicide Racer, mechanism of action and application rates

Field work includes the fight against weeds that suppress the development of useful crops. Herbicide Racer is a drug that has a selective inhibitory effect on weeds during the growing season. The product completely decomposes in the soil, without having a harmful effect on the growth of agricultural plants planted later.

Composition, purpose and release form of the herbicide Racer

The main component of the herbicide is flurochloridone, which belongs to the class of fluorine-containing substances.

The racer is used in processing fields from:

• ambrosia;
• quinoa;
• sow thistle;
• thistles;
• black nightshade;
• chamomile;
• tenacious bedstraw.

The racer is used to protect winter wheat, rye, corn, sunflower, potatoes, carrots, and parsley from weeds.

Release form: 25% emulsion in a 5-liter canister. The solution is applied by air spraying (air spraying).

Advantages and disadvantages

The drug belongs to the soil herbicides, allowing to control the growth of weeds before the emergence of the cultivated crop. The herbicide is indispensable in the fight against ragweed, grass, and quinoa.

The correct combination of the period of introducing herbicide into the soil and sowing cultivated plants prevents the inhibition of their growth by weeds at the beginning of the growing season.

Racer has low toxicity towards warm-blooded organisms, including humans (hazard class 2). In relation to insects, it has a hazard class of 3. It is prohibited to spray over a body of water due to the risk of harm to freshwater inhabitants.

Mechanism and speed of action

The action of the chemical compound is to suppress the photosynthesis reaction in the leaves of the weeds. The mechanism is carried out through penetration from the soil through the roots and stems into the leaves. The validity period lasts for 2 months.

The effectiveness of the drug depends on soil moisture. After spraying flurocholidone, rainy weather with a precipitation level of 25-30 millimeters is required in the first week. Reducing the amount of moisture to 10-15 millimeters will correspondingly reduce the effectiveness of the treatment.

Calculation of consumption for different plants

The manufacturer indicates the consumption rates of the active substance for spraying agricultural crops in the instructions. Based on the available data, in order to obtain 200 liters of a solution of the required concentration (2-3 liters per hectare), you need to mix 190 liters of water and 2x5 liter Racer canisters.

How to prepare a working solution

To prepare the working solution, use water with a temperature of at least 15 degrees, with a neutral or slightly acidic reaction. A clean tank is filled 1/3 with water, the required amount of emulsion is added, and mixed. Add the remaining amount of water.

How to use the ready-made mixture?

The instructions for use indicate the crops, planting dates, consumption of the active substance and the finished solution:

1. Potato. Air processing is carried out 2-3 days after landing. The concentration of the active substance is 200-300 grams per liter. The consumption rate is 200 liters per hectare.
2. Carrot. Spraying fields before emergence. The amount of active substance is 200-300 grams per liter, the consumption rate is 200 liters per hectare.
3. Sunflower. Tilling the soil before germination. The concentration of flurocholidone is 300-400 grams per liter. The herbicide consumption rate is 200-300 liters per hectare.
4. Wheat, rye, and corn are sown six months after Racer is added to the soil.
5. Tomatoes, onions, cabbage, radishes, pumpkins, and zucchini are planted a year after the fields are cultivated.

To effectively kill weeds, a single application of the herbicide throughout the year is sufficient. The application rate is adjusted depending on the soil structure: on loams with a large amount of organic matter it increases, on sandy loams it decreases.

Safety precautions for use

When preparing the working solution, it is necessary to protect your eyes, respiratory organs, and hands from contact with the emulsion:

• glasses;
• respirator;
• gloves.

Clothing made of thick fabric should cover the skin as much as possible.

Toxicity of the drug

Racer is phytotoxic to cereal plants and annual dicotyledonous weeds.

The drug does not pose a danger to humans if its concentration does not exceed:

• in soil – 0.03 milligrams per 1 kilogram;
• water – 0.04 milligrams per 1 liter;
• working area (air) – 1.2 milligrams per 1 cubic meter;
• potatoes – 0.1 milligrams per 1 kilogram;
• carrots – 0.1 milligrams per 1 kilogram;
• sunflower (oil, seeds) – 0.1 milligrams per 1 kilogram.

Signs of human poisoning with a herbicide occur at a concentration of flurocholidone of 0.04 milligrams per kilogram of weight.

Damage to the central nervous system has symptoms:

• slow reaction;
• unsteady gait;
• trembling in the arms and legs;
• drooping eyelids;
• inability to take a full breath.

For bees, the herbicide has a hazard class of 3.

Compatibility with other herbicides

To destroy the quarantine weed ragweed, Racer tank mixtures with soil herbicides are used:

• Acetochlor, which acts on weed seedlings for 3 months;
• Prometrex, which inhibits seedlings and adult plants;
• Triflurex, which affects the protein synthesis of germinating weed seeds.

Racer can be mixed with other soil herbicides.

The absence of sediment, foam, or signs of separation indicates the compatibility of the chemicals.

Storage rules and periods

The shelf life of the emulsion is 36 months from the date of issue.

Herbicides are stored in a dry room with plastered walls, natural ventilation, on a cement floor.

Analogues of the product

Soil selective herbicides similar to Racer in purpose, timing and methods of application to the soil:

• Base (active ingredient – ​​acetochlor);
• Promex (a.v. – prometrin);
• Dual Gold (active ingredient – ​​metolachlor);
• Challenge (d.v. – aclonifen);
• Zenkor Liquid (d.v. – metribuzin).

The difference lies in the preferred application for individual plants.
