Herbicide "Grims" is a one-component tool that allows you to cope with annual and perennial grasses, as well as some dicotyledonous weeds. It can be used for planting corn and potatoes. In order for the drug to give the desired effect, it is required to strictly follow the instructions for its use. Compliance with safety rules is important.

Active ingredient and dosage form of the drug

The herbicide is produced in the form of granules that dissolve in water. The substance does not have a pronounced aroma. The composition goes on sale in containers of 100 grams. The active ingredient is rimsulfuron. In 1 kilogram, its amount is 250 grams.

How it works and scope

"Grims" is predominantly absorbed by weed foliage and quickly shifts to merisystemic tissues of roots and shoots. The substance blocks acetylcholinesterase, a special enzyme involved in the production of amino acids. This causes weed cells to stop dividing, stop their growth and lead to death.

The tool helps to cope with such cereals as wild oats, different types of millet, timothy grass, couch grass. Also, the drug successfully destroys dicotyledonous plants - ragweed, thistle, field thistle, sowing vetch. This is not a complete list of plants that Grims can handle

The main advantages of the tool include the following:

high performance against a large number of grasses and dicotyledonous weeds;
long period of use - at the stage of appearance of 1-7 leaves;
no restrictions on crop rotation;
possibility of application in different security programs;
economical consumption - 40-50 grams of the substance is required per hectare;
ease of use - the composition is odorless and has a convenient preparative form;
high efficiency against creeping wheatgrass;
can be used in tank mixes.

How to apply the herbicide

Grims is mainly used with ETD-90 adjuvant. This substance helps to improve the penetration of the active substance into the weed. The optimal content of ETD-90 in the working solution is 0.1%. For 100 liters of working solution, you need to use 100 milliliters of the substance.

In drought conditions, the dose of working fluid should be increased to 300 liters per 1 hectare. At the same time, the amount of ETD-90 must also be increased to 300 milliliters.

"Grims" has a systemic effect on weeds, but does not have significant activity in the soil. As a result, it is possible to control the growth of only the grass that sprouted at the beginning of the application of the herbicide.

The most vulnerable phases of weed development include the following:

perennial root shoots - at the stage of formation of a rosette of leaves up to 10-15 centimeters in diameter;
annual dicots - from the formation of cotyledons until the appearance of 4 true leaves;
field bindweed - when lashes 10-15 centimeters long appear.

Like most analogues from the category of sulfonylurea, "Grims" begins to work already at temperatures of +5 degrees. However, the range of + 8-24 degrees is considered the best option. The absence of precipitation within 2 hours from the moment of processing is also important.

When exposed to overgrown weeds, it is important to apply the maximum dosage. Since "Grims" allows you to mainly control cereal weeds, in case of mixed weeding, it must be combined with anti-dicotyledonous herbicides "Lart" and "Asterix".

It is recommended to spray plantings at the stage of appearance of 2-6 corn leaves and 15-20 centimeters of potato sprouts or immediately after hilling it. For 1 hectare, 50 grams of the substance is required. In the absence of overgrown weeds or perennial grass, the dosage can be reduced to 40 grams.

Fractional use of "Grims" is recommended for uneven appearance of weeds and involves 2 treatments. For the first time, the procedure is carried out at the stage of up to 3 leaves of cereals and no more than 4 leaves of dicotyledonous weeds. In this case, it is worth using 30 grams of the substance per 1 hectare.

The second treatment is recommended when a new wave of weeds appears.At this stage, it is worth using 20 grams of the drug per 1 hectare. At the stage of the second treatment, it is worth adhering to the restrictions on the height of the potato. This indicator should not be more than 20 centimeters.
