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

Chemical weeding helps remove weeds from crops. Herbicides provide long-term protection against weeds, increasing yield and fruit quality. Gambit is a soil herbicide of systemic action, which, when the processing regulations are followed, does not have a negative effect on crops and does not cause resistance.

Active ingredient of the drug Gambit

Active ingredient herbicide - prometrin. The substance is a representative of the triazine class, developed in the 50s of the 20th century in Switzerland. In Gambit it is found in a concentration of 500 grams per liter.

Prometrin is one of the most popular herbicides of this class; many drugs have been created based on it. It has a soil effect, so it is most effective in the early stages of weed development.

Note that the peak of popularity of triazines (and prometrin) occurred at the end of the last century. Now the use of this group of herbicides is gradually being reduced.

Preparative form of the drug

The drug is prepared in the form of a concentrated suspension, poured into plastic canisters of 5 and 10 liters.

Spectrum of action of the herbicide

Gambit is intended for the destruction of cereals and dicotyledonous weeds:

Resistance to the action of the herbicide is demonstrated by various species of pickles and bedstraws.

Mechanism and speed of impact

Type of action – systemic. It enters sensitive plants from the soil (slightly through the foliage), through the root system and seedlings. The herbicide particles are carried through the conductive system to all tissues. Gambit suppresses activity:

• respiratory system;
• processes of chlorophyll formation – photosynthesis;
• inhibits the production and activity of enzymes.

The most powerful effect is at the stage of weed germination and for 4-7 days on young seedlings. Young shoots lose turgor, dry out and curl. After 1-2 weeks, the weeds completely die.

Increased soil and air temperatures accelerate the action of Gambit. An additional benefit is that the soil is kept moist when the herbicide is sprayed before weeds begin to grow.

Period of protective action

The duration of action of the herbicide is influenced by the weather - temperature, humidity. On average, the activity of the drug lasts 10-12 weeks.

Advantages and disadvantages

Let us note the properties of Gambit that determine its relevance and popularity:

• one treatment is sufficient - the protective effect lasts almost the entire growing season;
• absence of negative effects on the soil and protected crops;
• decomposes during the season, does not limit the change of crops during crop rotation;
• wide range of protective action - effective against a large number of weeds;
• convenient preparative form.

Gambit can be used at different times; its destructive effect on weeds is visible within a week.

The drug is not expensive; processing fields does not require high costs.

The herbicide is washed off by precipitation and when watering from the top layer of soil to the lower level (up to a depth of 1.2 meters). Due to this, it can enter reservoirs and artesian waters, polluting them.

Consumption rate

When preparing the working mixture for spraying, adhere to the following standards:

The working solution is used in a volume of 100-300 liters per hectare.

Preparation and use of the working mixture

Begin preparing the solution immediately before use. Mixing work is carried out on compacted or concrete areas where spilling the herbicide is not dangerous to the soil or plants.

The instructions for use indicate that the container with Gambit should be shaken vigorously beforehand to make the suspension homogeneous. Half the volume of water is poured into the sprayer container and the required amount of herbicide is introduced while the hydraulic mixer is operating.

The canister is washed several times with water, pouring it into the tank. Then add the remaining volume of water. During the entire spraying process, the mixture must be constantly stirred, so the hydromixer must not be turned off.

Rules of application:

• Gambit's properties are better revealed at a temperature of 10-20 °;
• timing of pollination – soil before sowing, during sowing, before and when the first shoots appear;
• the lower limits of the amount of herbicide are chosen for light fertile soils with a good degree of moisture;
• the maximum concentration and volume of the working solution is used on heavy, dry soils;
• when cultivating crops on peat soils, wait until seedlings emerge;
• if the humidity is insufficient, it is better to embed the drug into the soil (depth 2-5 centimeters);
• the soil should have a fine cloddy structure - large clods are broken, remnants of vegetation are removed.

The herbicide decomposes with the help of soil microorganisms, therefore, when the humus content in the soil is high, the upper volumes of the drug are chosen.

Note: It is recommended to loosen the crops after the weeds have died, since if the soil is disturbed, the effectiveness of the herbicide is reduced.

Safety precautions for use

The herbicide belongs to the 3rd class of hazardous substances. When working with it, protective suits, masks, and goggles are used.The solution is prepared at special sites, and the remaining mixture is disposed of.

After work, wash thoroughly using liquid products. If signs of poisoning appear, the person is removed from the area where the herbicide is being applied, clothes are removed, washed, and given sorbents. If signs of toxic effects persist, consult a doctor.

Phytotoxicity

If the consumption standards and regulations for use are observed, Gambit does not have a negative effect on the protected crops.

Possibility of resistance

To avoid addiction in plants, when treating crops, it is recommended to change herbicides to preparations with other active ingredients.

Compatibility with other chemicals

Gambit can be used to formulate complex mixtures with other herbicides to increase treatment efficiency and cover a wider range of weeds. Combined use with drugs containing C-metolachlor, trifluralin, acetochlor, and other active substances is allowed.

Before spraying onto crops, the mixture is tested for toxicity in a small area.

Storage conditions and shelf life

It is recommended to store chemicals in storage rooms. Storage in sealed containers at temperatures from -5 ° to +35 °. If the temperature drops significantly, the herbicide should be moved to another room, since the drug cannot be frozen to avoid loss of properties.

Existing analogues

The widespread demand for prometrin has led to the creation of several drugs based on it, which are analogues of Gambit:

• Alfa-Prometrin, ALFACHEMGROUP;
• Gesagard – Syngenta, Switzerland;
• Gezadar, AGRus;
• Honor, AFD Chemicals;
• Positive Plus, Himagromarketing;
• Fortis, RosAgroKhim.

All preparations contain 500 grams of prometrin per liter.

The use of soil herbicides prevents weeds from even appearing on the surface; they are destroyed in the bud. In order for Gambit to exhibit all herbicidal properties, the soil should be prepared and the drug should be applied on time in the appropriate dosage. A single treatment of crops is required; the drug does not have a negative effect on the quality of fruits.
