Herbicide Grader: instructions for use, mechanism of action, consumption rates

The group of imidazolinones belongs to highly active and selective herbicides. They are used to clean heavily weedy fields of rapeseed, sunflower, peas, soybeans, non-agricultural land. The use of herbicide "Grader" from the company "August" helps farmers grow forage crops, increase yields, and also prepare sites for construction.

Composition and release form of Grader herbicide

A heavy-duty continuous herbicide can deal with annuals, perennials, shrubs, trees that cover non-agricultural areas.The drug is used in fields where hybrids of rapeseed, sunflower, pea varieties resistant to imidazolinones are grown.

The formulation of the herbicide is an aqueous solution of imizapyr, ready to use. A liter contains 250 grams of a substance. The ready-made working solution of the herbicide is poured into 1 liter bottles, canisters - 10 liters.

Advantages and disadvantages

The drug has many advantages. Note that Grader herbicide:

destroys all types of weeds, unwanted shrubs, woody shoots;
acts systemically, penetrating inside the plant;
remains in the soil, stopping the development of young weeds;
protects the treated area from weeds throughout the year;
does not wash off with rain;
has moderate toxicity to humans, bees.

Aqueous solution acts effectively at any stage of plant development, regardless of their contamination.

The disadvantages of the drug include the fact that it can destroy crops located near the place of processing.

Mechanism and speed of action

The action of the active substance imazapyr begins with a h alt in the growth of grasses and shrubs on the treated area 7 days after spraying. After 30-45 days, everything that grew on the field dies. Therefore, herbicide spraying is used to clean areas overgrown with weeds and shrubs near highways, railroad tracks, and runways. With the help of an aqueous solution, areas for the construction of houses, gas pipelines, power lines are freed from weeds. Fields with rapeseed and sunflower can be treated with this herbicide when hybrids resistant to the drug are planted.

No vegetation will appear on the site for 3-5 years after spraying.

Expense calculation

For non-agricultural land, 2 to 5 liters of water solution are used per hectare. Processing is carried out from April to September.

The destruction of annual grasses and dicotyledonous weeds should be carried out in the 2-4 leaf phase.

At the same time, sunflower and rapeseed should have up to 5 real leaves. Only 0.12 liters of herbicide solution is needed per hectare of field.

How to prepare a working solution

The working fluid is prepared in a special atomizer tank. First, the container is filled with clean water by a third. The required amount of the agrochemical aqueous solution is then carefully added. Stir thoroughly, adding to the full volume of the tank.

Do not pre-prepare the liquid, just before spraying.

How to use the product

Toxic substance requires instructions for use to be read before spraying it on wastelands or forage fields.

Processing is carried out mechanically in compliance with safety rules. It is best to spray areas in the early morning or after sunset. The weather should be calm, calm.

Safety when using

There are restrictions on the use of herbicide. Be sure to take into account the location of the area under processing. It should be located 1.5-3 kilometers from water basins, parks, forest plantations, fields with grain crops, apiaries. It is necessary to control the departure of bees to the treated areas. Nearby there should be no pastures for cattle, private gardens, orchards, recreation centers.

Phytotoxicity and potential for resistance

Greyder herbicide has been assigned the 3rd class of toxicity for humans and bees. The drug is not considered dangerous for microorganisms, worms living in the soil.

The chemical is toxic to rodents, harmful insects.

Weeds do not develop addiction to the drug for a long time. Vegetation will take a long time to recover in the treated area.

Compatibility with other herbicides

Suitable agrochemical "Grader" for tank mixes. Before use, check compatibility with other drugs. If there is no sediment, then you can safely use the combination of "Grader" with "Tornado", "Magnum". The effectiveness of the agent increases if the herbicide is combined with preparations of the 2.4D type, metsulfuron agents.

Rules and terms of storage

Container with herbicide solution must be tightly sealed.Storage is carried out in specially designed rooms inaccessible to children and animals. The room must be equipped with fire extinguishing equipment. Cleaning the premises is carried out at least 1 time per month using disinfectants such as bleach. Store the drug for no more than 3 years.

Means analogues

Imperial, Arbonal, Arsenal are produced based on imidazolinones. They act similarly to the Grader herbicide, clearing large areas of continuous weeds.
