The composition successfully copes with annual dicotyledonous weeds. With its help, it is possible to destroy the field thistle, ambrosia, sparrow. Also, the substance inhibits the growth of chickweed, mustard and other plants.

Composition and formulation of the herbicide

The active ingredient of the product is tribenuron-methyl. In 1 kilogram of the product there are 750 grams of this component. The composition belongs to the chemical class of sulfonylurea. It is produced in the form of water-dispersible granules.

The product is sold in a package of 600 grams. It contains 30 water-soluble bags of 20 grams.

The principle of action and purpose of the drug "Grand Plus"

Tribenuron-methyl is considered to be the active component of the herbicide. This substance belongs to the chemical class of sulfonylurea. The active substance differs in systemic activity. It is absorbed by the foliage and root system of plants and easily moves through the weed structure. In susceptible plants, the herbicide inhibits the enzyme acetolactate synthase. This substance takes part in the production of valuable amino acids. When the enzyme is suppressed, grass growth quickly stops, and then it dies.

The substance produces a herbicidal effect on susceptible weeds for 1 month. Under certain conditions, a second wave of grass may appear.

However, many cereal plants are resistant to the active component of the product. This applies to winter and spring wheat. To a lesser extent, this is true for oats and barley.

The main benefits of the herbicide include the following:

1. Different in high efficiency. At the same time, the composition is selective in relation to cereal plants.
2. It has a broad spectrum of influence on weeds, which is resistant to hormonal herbicides - MCPA, dicamba, 2,4-D. Therefore, the product can be used against many types of weeds, including those resistant to other herbicides.
3. Applicable in cold spring. The substance does not provoke toxic effects.
4. Decomposes in the soil structure in a short time. Therefore, there are no restrictions on other plants, subject to the rules of crop rotation.
5. Affects enzymes that are found exclusively in plants. Because the substance is almost safe for animals and humans.
6. It is a systemic agent that is absorbed by the foliage.
7. Helps significantly reduce herbicide load on the soil.

The development of sensitive weeds stops within a couple of hours after using the product. At the same time, it is possible to significantly reduce the consumption of useful elements and water. Noticeable manifestations occur 2-3 days after treatment. In this case, the complete death of weeds is observed later. This happens after 10-15 days or later - it all depends on the weather.

Dosage and application

To avoid an overdose of the product, it is important to properly set up the equipment. When processing, it is important to avoid re-applying, turning or slowing down. The cost of the working fluid, on average, is 200-300 liters per 1 hectare. It is important to avoid contact with other agricultural plants, as they may be susceptible to this herbicide.

The most pronounced effect of "Grand Plus" produces during the active development of young weeds. It is recommended to use it at the stage of appearance of 2-4 leaves. Symptoms vary depending on grass variety, growth stage and weather.

The first signs in the form of chlorosis and necrosis are observed a few days after treatment. At the same time, after 1-2 weeks, the weed completely dies. When using formulations for less susceptible weeds, signs may appear later in the later period or during drought. Individual weeds, which are of medium sensitivity, remain green for a long time. However, their development has already been suppressed.

After a couple of hours after treatment, the grass stops developing and stops absorbing water and minerals from the soil structure. Thus, there is no competition with cereal crops.

It can be concluded that the increased selectivity of the herbicide in combination with effective control of the development of weeds at an early stage of development helps to achieve high yields of cereals. To get this effect, you should follow the rules for using the substance. The dosage of the product is given in the table:

Annual and individual perennial dicotyledonous weeds

Culture	Substance use rate, grams per 1 hectare	Weed	Features of use	Waiting period (number of treatments)
Oats	15-20	Annual dicotyledonous weeds, including resistant to 2,4-D and 2M-4X	Spray plantings need at the stage of 2-3 leaves. This is done at the initial stage of tillering and in the early stages of weed growth. 200-300 liters of working solution are required per hectare.	60 (1)
Spring and winter cereals , except for oats	20-25	Annual dicotyledonous weeds, including those resistant to 2,4-D and 2M-4X, field calendula	It is necessary to spray crops at the stage of tillering and at the initial stages of weed growth.Winter plantings are processed in the spring. 200-300 liters of working solution are required per 1 hectare. -50
Spray plantings in the phase from 2-4 to 6-8 true leaves and in the initial stages of weed growth herbs. For 1 hectare it is worth spending 200-300 liters of working solution.

Precautions
