Zenkor and Zenkor Ultra weed killers: instructions for use (photo)

Fertilizers and preparations

Weeds are always the true enemy of summer residents and gardeners. If you run a large farm, however, weed control can escalate into a full-blown battle. To avoid stress and prevent the labor-intensive process of weed control from becoming a simpler procedure, you should familiarize yourself with a product called Zenkor Ultra.

Modern agronomists recommend choosing this herbicide over the many commercially available chemicals. Zenkor Ultra is a safe, selective herbicide. This means it kills weeds but leaves potatoes and other cultivated vegetables untouched. Weeds interfere with the metabolism of nutrients in vegetables and hinder potato growth. The instructions for Zenkor Ultra weed control recommend abandoning the traditional, grueling methods of weed control. These new products provide long-lasting results and are used only 2-3 times during the entire gardening season. Weed control is most effective when they are just beginning to grow. This is what Zenkor Ultra is designed for.

It comes in a wettable powder form. It is applied before plant emergence, on practically bare soil, after plowing. A single application of the herbicide rids the field of dicotyledonous and monocotyledonous weeds such as ragweed, shepherd's purse, deadnettle, and chickweed.

Weeding is ineffective, especially during the rainy season. Gardeners need a chemical that will eliminate all weeds and leave only potatoes in their beds. Zencor, a leading herbicide for weed control, is such a product. It is designed to kill broadleaf dicotyledonous weeds and annual grass weeds. It is a selective herbicide, meaning it kills weeds without harming cultivated plants. Its affordable price makes it suitable for large plantings of potatoes, tomatoes, carrots, and other crops.

Thanks to the main component, all fertilizers that contain it have a long-lasting effect, as they dissolve slowly and remain active in the fertile soil layer for almost the entire gardening season.

Description of the product "Zenkor Ultra"

The key properties of Zenkor Ultra help gardeners quickly eliminate weeds. These properties make it suitable for use in both private gardens and industrial-scale plantations. Experience has shown that it is most effective on potato plantations.

Important action: It doesn't interfere with the growth of the main crop in the field; the potatoes grow and thrive, but weed growth is suppressed, regardless of the growth stage—even in the form of ungerminated seeds. The very first treatment of the field completely removes all weeds from the area.

Zenkor creates a protective film on the soil that prevents weed growth in the treated area. This protective film is long-lasting, killing grass and broadleaf weeds. Zenkor's active ingredient is Metribuzin, a well-known ingredient among agronomists and soil technicians. Its safety for growing food crops has long been proven and time-tested.

Metribuzin's ability to affect plants in all their growth stages is enhanced. The herbicide penetrates the roots through the root system, infecting the shoots and infecting the entire mature plant. Metribuzin also attacks the foliage of mature plants, destroying them and then penetrating all parts of the plant, causing further damage. The active ingredient belongs to the class of triazinone derivatives.

Zenkor is also used as part of a garden weed control mixture. Several herbicides are mixed in a tank, and the addition of Zenkor enhances the tank mix's spectrum of activity. The herbicide is effective only until the potato rows form a smooth carpet of foliage.

You need to know! The active component of the drug, Metribuzin, according to the classification of the Ministry of Health, is classified as hazard class III for humans and class IV for bees.

Composition of the drug Zenkor Ultra

The main ingredient in Zencor Ultra, responsible for its action, is metribuzin. Its chemical formula is C8H14N4OS. It belongs to the class of triazinone derivatives. Zencor contains metribuzin in a ratio of 7:10, or 70%. Zencor contains 600 g/L of the active ingredient in dissolved form.

The chemicals in the packaging are identical in their composition and effectiveness. Zenkor is available in various packaging sizes:

powder in 20 g sachets;
in bottles up to 100 ml;
in tanks up to 5 l.

Accordingly, large-volume packaging is purchased by farmers for processing large plantations, while small-sized packaging is produced specifically for use in summer cottages and private farms in rural areas.

Please note! The packaging allows for convenient dosing for a large plantation or a small garden plot. The liquid form of the product is an excellent base for mixing in tanks.

Advantages of Zenkor Ultra

Zencor's action and long-lasting stability on the surface layers of the soil allow it to be used after spring rains, ensuring weed control throughout the season.

The drug "Zenkor Ultra" has many advantages:

Weeds do not develop resistance to it;
easy to use;
no pre-dissolution required;
it can be used in different climatic zones of the country;
efficient spending;
the sprayer filters remain clean;
granules dissolve completely, without sediment;
perhaps spraying plantations, beds on freshly plowed, just sown soil, and already when seedlings appear;
The herbicide has no distinct odor.

A special advantage of Zenkor Ultra is its lack of danger to humans and beneficial insects. It does not harm the phytohealth of neighboring crops and is non-toxic.

Important! In large garden plots and summer cottages, crop rotation is always planned. The use of herbicides containing Metribuzin does not interfere with crop rotation plans.

Toxicity of Zencor

Research has shown that any herbicide should be used strictly according to its instructions. This will ensure a high yield and will not have a negative impact on vegetables or human health. Zencor does not accumulate in the soil and is therefore considered completely safe, despite its intimidating name, "herbicide." This name is frightening to anyone unfamiliar with modern weed control products.

Medicines of the future! Ongoing scientific research continually improves safety levels, and manufacturers compete for market share and produce products completely free of harmful substances.

The principle of operation of Zencor

It's beneficial to treat the soil with Zenkor before the first shoots appear, as this creates a protective barrier against weeds. Once the shoots emerge, the film penetrates the weeds' growth, inhibiting their photosynthesis. The product works on weeds both through the emerging shoots and through the soil. This is why it's important to keep the soil moist before applying the herbicide. For the same reason, before applying herbicide to potato plantings, it's recommended to check the weather forecast for the week to prevent rain from washing the herbicide out of the soil.

The active ingredient is a systemic pesticide. It is readily absorbed by the shoots and root system, resulting in the death of the entire plant. The substance works by inhibiting electron transport during photosynthesis, resulting in the immediate death of the weed.

Metribuzin's excellent action is through the leaf surface. When sprayed on plants, Zencor hits the leaves, and its active ingredient, Metribuzin, penetrates the leaf structure into the plant stems, killing them. Metribuzin is destructive to both monocotyledonous and dicotyledonous weeds. With its dual effect on roots and foliage, Metribuzin has a long-lasting effect on arable land. If the product is used before the first shoots emerge, sensitive weeds will not grow at all.

Important: Check the weather forecast. Wet weather promotes faster germination, while dry weather takes a little longer. Protection lasts for a month.

How to use Zencor

Metribuzin-based products—Zenkor and its analogs—have long been successfully used by gardeners around the world, and their effectiveness is widely recognized due to their numerous positive aspects. This is reflected in the characteristics of the herbicides themselves and in the technologies used to apply them. Zenkor Ultra is produced in several forms: granules, dispersible powder, suspension, and liquid concentrate. These different formulations offer advantages in use: the mixture is quickly diluted; the solution is physically stable; and no sediment remains in the container.

Instructions for use

Each package of Zencor comes with instructions for use. This essential accompanying document will help users easily understand the instructions for use, application times, and spraying techniques.

The working mixture is applied with a hand-held sprayer. Some manufacturers warn that eye and respiratory protection should be worn, while others consider this an optional precaution. However, herbicides are chemicals, and it's reasonable to assume that protection is still necessary, just as we take certain measures to protect ourselves from even household chemicals.

The higher the quality of the sprayer, the more effective the application will be. Zenkor is easy to use; no special preparation of the potatoes is required before application. Simply plant the root crops, plow the area, and immediately apply Zenkor to the soil while it still retains high moisture.

Manufacturers recommend treating the field with a preparation of one brand in several steps during the gardening season:

Treatment before the first sprouts appear; apply 2-3 days before potato growth begins. According to the growth cycle of different plants, dicotyledonous weeds begin to emerge from the soil by this time, and herbicide treatment is just in time to kill the weed sprouts. This is according to the instructions for using Zencor on potatoes. To ensure the film protects potato plants longer, avoid loosening or watering the soil.
Post-emergence treatment is carried out a couple of weeks after the first spraying. Experienced gardeners base this treatment on the height of the potato sprouts, which should not exceed 5 cm.

For the first and second treatments, a different concentration of the working solution is recommended, therefore, less powder is used the second time than when preparing the first solution.

Must know! Zencor's instructions strictly prohibit treating plantations and beds during the middle of the day. This should be done either early in the morning or at sunset.

How to dilute chemicals

In accordance with the manufacturer's requirements, the dosage of the product is calculated based on the properties of the regional soil.

Consumption for the first treatment:

for light chernozem soil – up to 0.6 l/hectare;
for average podzolic soil – up to 0.75 l/hectare;
for heavy clay soil – up to 1.2 l/hectare.

It is best to spray Zenkor Ultra immediately after light rain, as humidity significantly increases the effectiveness of the product.

The dilution rate for the chemical depends on the plant to be controlled. Granular chemicals are diluted at a rate of 15 g per 5 liters of water. Complete dissolution takes ½ hour. Liquid chemicals require 7-11 ml per 5 liters of water. In any case, the instructions for each package contain detailed instructions for preparing the working solution for each soil type.

Precautionary measures

Herbicides containing the active ingredient Metribuzin are considered virtually harmless to humans and the environment. However, there are certain rules that must be followed when working with chemicals of any safety class.

There are also precautions:

This herbicide must be applied according to the manufacturer's instructions and the dosage must be followed. However, this will only cause yellowing of the foliage on mature plants, but will not cause harm to humans from the ripened fruit. Yellowing of foliage most often occurs after herbicide treatment of large, open fields with sandy soil.
Another warning from the manufacturers of Zencor and its analogues: do not treat early potato varieties.
Manufacturers recommend not eating, drinking, or smoking before weeding. After finishing work and cleaning up equipment, it's recommended to thoroughly wash your face and hands with soap, even if you were wearing protective clothing.

The herbicide is considered completely safe. Complications are extremely rare, occurring only in cases of direct, immediate contact. These may include allergic reactions, irritation, or dermatoses, which, of course, require medical attention.

Special warnings:

The disposal of herbicide waste requires special attention. This is a technically complex process, requiring adherence to specific regulations and knowledge of disposal technology. If the waste is very small, basic rules should be followed, which require burying the remains of herbicide mixtures only in a designated area, away from bodies of water and water intakes, in a deep pit.
The disposal of remaining Zenkor mixtures and packaging requires adherence to strict rules: underground structures must be located far from residential areas and bodies of water.

Compatibility with other pesticides

Zencor, Zencor Ultra, and its analogs, which contain the active ingredient Metribuzin, offer a wide range of potential applications with pesticides. Therefore, Zencor can be used in complex mixtures or as a standalone product for staged pollination of plantations. Manufacturers recommend combining the product with their own products and purchasing products in advance with compatibility information.

Rules for storing the drug

The expiration date and storage instructions are specified in the instructions for use and are always indicated on each package. Zenkor and Zenkor Ultra can be stored for 2 years from the date of manufacture. Some companies specify a shelf life of at least 3 years from the date of manufacture. Storage temperature ranges from -10°C to +40°C.

Do not transfer powder or liquids to other containers during storage. Keep chemicals in their original packaging, with the label intact. The designated storage area should be dry and cool. The storage area should be securely separated from animal feed, fuels, and lubricants. This area should be a designated area specifically for the temporary storage of pesticides.

A must! Store herbicides out of the reach of children.

Reviews of Zencor

Zenkor Ultra has earned positive reviews because it's relatively safe, doesn't accumulate in the soil, and doesn't harm crops. Experienced gardeners give positive reviews for its effectiveness, convenient dosing, and ease of use. Consumers also appreciate its format—powders, fine, water-soluble granules, and liquids. To prepare them, simply pour the chemical from the bottle into a container of water and mix thoroughly. Another reason for Zenkor's positive reviews is its affordable price.
