Zenkor herbicide: instructions for use, composition and release form of the product

Zenkor herbicide is widely used in agriculture, detailed instructions for use are attached to the chemical preparation, which is available in the form of powder, granules or concentrated emulsion. The destruction of weeds is carried out before sowing and after germination of plants. From the moment of processing to the death of weeds, it takes from two to three weeks.

Composition and release form of the product

Zenkor, a German weed killer, has been known for a long time. New generation chemicals - Zenkor Ultra and Liquid, have an improved herbicide formula with a reduced content of the main substance - metribuzin, which did not affect the quality of the chemical.

The first preparations were produced in the form of powder and granules in 20-gram bags or 5-kilogram packs. Now the release of an emulsion or suspension in bottles of 20 or 100 milliliters has been established, which dissolve better in water and foam less .

Pros and cons

Like any chemical substance, Zencor has its positive and negative properties. The advantages include the following: ease of use, filters do not clog when spraying, does not have a strong odor, an effective and relatively safe product.

The minus of the herbicide is that this product cannot be used to treat the beds on which garden and garden plants that are not compatible with the chemical are grown annually. These crops include: onions, garlic, lettuce, cabbage, melons.

Mechanism of action

When processing the area, metribuzin, which is part of the herbicide, penetrates the roots of the weed and begins to circulate throughout the plant, gradually destroying it. The uniqueness of the drug lies in the fact that the herbicidal composition can penetrate into the weeds not only through their root, but also through the leaves.

Preparing the solution

Zenkor in powder or granules completely dissolves in water within thirty minutes. Before use, the solution must be stirred until the complete disappearance of small particles.

Herbicide in suspension mixes quickly with water, does not clog filters when sprayed.

Consumption rate

The amount of chemical used is related to several factors.

First - you should pay attention to the amount of weed on the site; the more it is, the more saturated the solution is made, but not higher than the maximum dosage.

Second - the consumption of the herbicide depends on the type of vegetables grown. For example, 200-300 milliliters of the product is used per hectare of carrots or cereals, and 0.7 liters for potatoes and tomatoes. Also, the amount of herbicide used depends on the structure of the soil.

500-700 milliliters of the substance is used to treat one hectare of sandy soils.

For black soil, you will need from 700 milliliters to a liter of solution per hectare. Clay soil is treated with 1.0-1.65 liters of prepared substance.

Instructions for the complex use of weeds

Zenkor is an excellent tool in the fight against weeds. The first spraying of the soil must be carried out in the spring. A protective film forms on the surface of the treated area, which should not be destroyed. After germination, the herbicides penetrate the structure of the weeds, destroying them.

Before spraying, it is necessary to level and moisten the soil surface. The solution should be applied evenly over the entire area. The minimum dose of the drug is used on light soil. Accordingly, for heavy soil use the maximum dose.

Tomatoes

The land under the tomatoes grown from seeds is treated after the appearance of two to four true leaves on the plant. Tomato seedlings are recommended to be planted in already cultivated soil. A solution for tomatoes is prepared from seven grams of the drug and five liters of water.

Potatoes

Depending on the structure of the soil, the solution is prepared from 5-15 grams of herbicide and 5 liters of water. The site must be processed before the shoots of potatoes.

Soybeans

Soybeans are processed similarly to potatoes.

Carrots

You can spray the soil under carrots before germination or at the time of root formation. A solution for ordinary soil is prepared from 10 grams of the drug and 5 liters of water.

When is it better not to use?

Some types of vegetables and herbs are sensitive to Zenkor, so the drug does not need to be used in fields with crops such as pumpkin, cabbage, beets, peppers. Also, the herbicide is dangerous for onions, garlic, lettuce.
