How to use Zenkor against weeds for potatoes
Herbicides are formulated for effective pest control. They have a neutral effect on the soil. The taste and quality of vegetables does not deteriorate from them. They are easy to use. After using them, the land does not need to be fertilized for the next year.
Characteristic
Zenkor is a broad-spectrum drug. It is used for various horticultural crops: tomatoes, soybeans, carrots, apple trees, pears, etc. But it gives the best results for potatoes. It is rational to use it on large fields.
According to the instructions, it has the following characteristics:
- spectrum of activity of the drug - annual dicotyledonous, cereal weeds;
- systemic nature of the action;
- suspension concentrate (liquid creamy solution) or in the form of water-soluble granules;
- minimum exposure temperature - 10 ° C, maximum - 35 ° C.
The product is produced in Germany, it is stored at room temperature so that the sun's rays do not fall on it.
1 package can contain 20 or 100 g, if it is a bottle. For home use, 5-20 granules weighing 20 g are sufficient. The active ingredient is metribuzin.
Composition
The effect of a drug depends on its components. The main components of Zencora Ultra are active chemicals.
Metribuzin inhibits the transport of electrons in the photosynthesis of pest plants. Subsequently, the weeds die and dry out.
The duration of exposure is explained by the ability of metribuzin to penetrate the leaves and roots. Other herbicides are limited to the roots, which is sometimes insufficient for weed control.
Features of the drug
The weeds are retreating
The product destroys broadleaf and cereal pests, is non-toxic to animals, people, soil and the environment.
Based on the instructions for use, the drug has a number of features:
- fights a lot of weeds;
- completely dissolves in water in 10-15 minutes;
- applied before and after potato shoots;
- not addictive to pest plants;
- processing of a large amount of land is possible;
- used both independently and in conjunction with pesticides;
- promotes soil cleanliness for at least 2 months;
- used as an agrochemical in the agricultural industry or private fields.
Thanks to Zenkor Ultra, crops grow quickly, get enough water and light. The drug saturates the soil with nutrient and mineral components.
In accordance with the instructions, the liquid is mixed with other herbicides. This is necessary to enhance the spectrum of action. The solution damages the underground and aboveground parts of the potato, prevents the development of any mechanically transmitted viruses. The herbicide should not be applied to sandy soil. The leaves of the plant may turn yellow and fall off. The root will dry out slightly.
Drug action
Zenkor kills weeds that have already come down. After the preparation, they simply dry out. For the next season, the soil can be left untreated. In the future, the probability of the appearance of weeds in the next 3 months is zero. Treatment with a product will help when the plants have just begun to germinate.
The effectiveness of the action depends on the average air temperature, soil moisture, soil type.
The herbicide creates a protective film on the surface of the land and crops. After mechanical treatment of the soil, the shell is destroyed. This mechanism of action is realized before the rise of cultures.
After germination, metribuzin is actively involved. Processing speed - a week or 14 days.
Zenkor does not increase the yield, but prevents it from decreasing. To achieve the desired effect, be sure to follow the instructions for use in the instructions.
What weeds are used for
Working without grass is much easier
Thanks to its wide range of applications, Zenkor copes with a large number of weed plants. Their list:
- wild chamomile;
- ambrosia;
- amaranth;
- deaf nettle grass;
- kalachiki;
- yellow thistle;
- medium stellate;
- thin-legged, etc.
Zenkor shows low efficiency with a small amount of humus in the soil. It is also not recommended for use against field bindweed, black nightshade, creeping wheatgrass and bedstraw. If the pest plants are perennial, Ultra will not help.
Application
Initially, it is necessary to level the soil and break it into lumps. Zenkor is diluted with water. According to the instructions for use, the consumption rate for potatoes does not exceed 11 ml of the drug per 5 liters of water. This is enough for one hundred square meters.
The drug is sprayed with a sprayer. The main requirement is to distribute the product evenly throughout the entire area. The preparation should saturate the soil by at least 3 cm.
The dose depends on the type of soil. For heavy soils, take the maximum (11 ml), for light and airy soils - the minimum (5 ml).
If rainy weather is foreseen, processing is carried out in the morning, 4-5 hours before rain. The rain will moisten the soil and Zenkor Ultra will penetrate deep inside.
Recommendations
In order not to harm anyone during the soil treatment with Zenkor Ultra, it is important to follow the tips:
- During dry periods, use the maximum allowed amount, during the rainy season, use the minimum dose.
- Use the product only outdoors. Soil cultivation in greenhouses and greenhouses can increase phototoxicity.
- Observe the consumption rates - 200-300 ml per 1 hectare.
- Do not throw product residues into open water.
If everything is done correctly, the suppression of weeds will be rapid, reaching the closing of the tops in separate rows.
Restrictions on use
Zenkor Ultra cannot be used in too dry and hot weather due to evaporation. High humidity will not allow the preparation to penetrate deep into the ground. Heavy rains can wash out the drug and render it ineffective.
Exceeding the recommended dose will lead to a deterioration in the quality of the potatoes. In the fruits, darkening is formed, the leaves turn yellow or turn white. The tips become dry and crumble.
You should not treat the land with a herbicide with a strong sensitivity of different varieties of potatoes to any herbicides. For cereal plants with legumes, the remedy will be ineffective. If frequent frosts, a sharp change in weather, drought are possible, the product should be discarded. It is used with extreme caution in planting early potato varieties.
Conclusion
Zenkor Ultra is an excellent weed control agent. Just 5-11 ml per 5 liters of water is enough for 1 are of land. In addition to the protective function, the drug provides potatoes with nutrients, does not harm animals, other crops (carrots, tomatoes, soybeans). Not a threat to human health.
Pay attention to the weather conditions before treating the soil. In anticipation of rainy weather, the herbicide is sprayed in advance.At the same time, make sure that the temperature is not lower than 10 ° C and not higher than 35 ° C. Under the influence of the drug, the taste of potatoes does not suffer.
