Herbicide Racer: instructions for use, mechanism of action and consumption rates

Field work includes the fight against weeds that inhibit the development of useful crops. Herbicide Racer - a drug that has a selective inhibitory effect on weeds during the growing season. The agent completely decomposes in the soil, without adversely affecting the growth of agricultural plants planted later.

Composition, purpose and release form of herbicide Racer

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

Racer is used in processing fields from:

• ambrosia;
• swans;
• thistle;
• baddies;
• black nightshade;
• daisies;
• tenacious bedstraw.

Racer is used to control weeds of winter wheat, rye, corn, sunflower, potato, carrot, parsley.

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

Advantages and disadvantages

The drug refers to soil herbicides that allow you to control the growth of weeds before the emergence of cultivated crops. The herbicide is indispensable in the fight against ambrosia, shiritsa, quinoa.

The correct combination of the period of application of the herbicide in the soil and sowing of cultivated plants prevents the oppression of their growth by weeds at the beginning of the growing season.

Racer has low toxicity to warm-blooded organisms, including humans (hazard class 2). In relation to insects, it has a hazard class 3. Do not spray over water due to risk of harm to freshwater life.

Mechanism and speed of action

The action of a chemical compound is to suppress the reaction of photosynthesis in the leaves of weeds. The mechanism is carried out due to the penetration from the soil through the roots and stems into the leaves. The validity period is valid 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 accordingly reduce the effectiveness of processing.

Calculation of consumption for different plants

The manufacturer indicates the consumption rates of the active substance for spraying crops in the instructions.Based on available data, to get 200 liters of solution of the desired 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 a working solution, use water with a temperature of at least 15 degrees, with a neutral or slightly acidic reaction. A clean tank is filled with water by 1/3, the required amount of emulsion is added, mixed. Add the remaining amount of water.

How to use ready mix?

In the instructions for use, crops, planting dates, consumption of the active substance and the finished solution are indicated:

1. Potatoes. Aerial processing is carried out 2-3 days after landing. The concentration of the active substance is 200-300 grams per liter. Consumption rate - 200 liters per hectare.
2. Carrots. Spraying fields before germination. The amount of active substance is 200-300 grams per liter, the consumption rate is 200 liters per hectare.
3. Sunflower. Soil tillage before emergence. The concentration of flurocholidone is 300-400 grams per liter. The herbicide consumption rate is 200-300 liters per hectare.
4. Wheat, rye, corn are sown six months after the Racer is introduced into the soil.
5. Tomatoes, onions, cabbage, radishes, pumpkins, zucchini are planted a year after the fields have been cultivated.

For the effective destruction of weeds, a single application of the herbicide during the year is sufficient. The consumption rate is adjusted depending on the structure of the soil: on loams with a large amount of organic matter, it increases, on sandy loams it decreases.

Safety when using

During the preparation of the working solution, it is necessary to protect the eyes, respiratory organs, hands from getting the emulsion:

• glasses;
• respirator;
• gloves.

Clothes made of dense fabric should cover the skin as much as possible.

Drug toxicity

Racer is phytotoxic to grasses and annual dicotyledonous weeds.

The drug is not dangerous to humans if its concentration does not exceed:

• in the 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 herbicide poisoning occur at a flurocholidone concentration of 0.04 milligrams per kilogram of body weight.

Death of the central nervous system has symptoms:

• delayed response;
• unsteady gait;
• trembling hands and feet;
• drooping eyelids;
• inability to take a full breath.

For bees, the herbicide has a hazard class 3.

Compatibility with other herbicides

For the destruction of the quarantine weed ragweed, tank mixtures of Racer with soil herbicides are used:

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

Racer can be mixed with other soil herbicides.

Lack of sediment, foam, signs of delamination indicates the compatibility of chemicals.

Rules and terms of storage

Emulsion shelf life is 36 months from the date of issue.

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

Means analogues

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

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

The difference lies in the preferred application for individual plants.
