The drug Zenkor Liquid is well known to both professionals and amateur gardeners who have chosen vegetables as cultivated crops. All of them require reliable and highly selective weed control. The German company BAYER has developed an innovative formulation for the herbicide Zenkor Liquid 600 SC. The product provides an equivalent or even better result in comparison with the previous Zenkor Liquid in the form of water-soluble granules WG 70, while there is no need to increase the dose of the herbicide.
Group: Herbicides
Active ingredient: metribuzin 600 g/l
Preparative form: suspension concentrate
Packaging: 5 l
Key advantages Herbicide Zenkor Liquid (Zenkor Liquid Ukrainian) produced in the form of a suspension concentrate ensures the achievement of a higher quality and stable solution for work, increases the activity of the main ingredient and significantly reduces the possible risks of product sedimentation when using side mixes. Zenkor® Liquid as an SSR for post-emergence treatment is optimally combined with other herbicides, the active substance of which is rimsulfuron (on those cultures where it is registered for use). In this variant of crop treatment from weeds, the dose of Zenkor® Liquid does not exceed 200–300 ml/ha, depending on the consumption dose of the partner drug. The product can be sprayed on the land both before and after crop emergence. Such a wide window allows for a sufficiently long period of action of the herbicide. At the same time, the high selectivity of the inhibition of plants, in relation to the cultivated culture, is observed. The effectiveness and reliability of the herbicide Zenkor Liquid is perfectly demonstrated on monocot broad-leaved and grass weeds. If the recommended norms of the drug are observed, the toxicity for bees is minimized. However, the herbicide should be used with caution near water bodies.

The mechanism of drug influence
The main active substance is metribuzin, which has the property of being easily and quickly absorbed into the root system and shoots of weeds, and if necessary, it is also absorbed by the leaves. Inside the plant, it moves acropetally (roughly speaking, from the base to the top). The systemic influence of metribuzin is ensured by its ability to inhibit the process of photosynthesis in plants. Correspondingly, weeds quickly die without the ability to "breathe".
The effect of applying
Zenkor Liquid when applied before emergence actually does not even allow weeds to germinate, and when applied after emergence, weeds die in 10-20 days. Compliance with the manufacturer's recommendations for using the drug effectively protects crops from weeds for at least 1-2 months. Also, thanks to the ability to stay on the ground for some time, the second wave of clogging is removed.
Features of processing
When processing the fields of SZR Zenkor Liquid, if there is a need for reseeding for objective reasons, it should not be done with pepper,
cabbage, onions, lettuce, sugar and table beets,
spinach, pumpkin, tobacco, rapeseed, cucumbers. It is also not recommended to plant onion and beet types in the next hour after the herbicide is applied. These cultures are considered sensitive to the drug. If the maximum permissible dose of herbicide is used for processing soybeans, a certain loss of leaf color is sometimes observed. This phenomenon disappears on its own over time and does not affect the overall yield in any way. Zenkor Liquid is usually well perceived by many varieties of potatoes. In rare situations, under stress or other adverse conditions for culture, slight discoloration of potato leaves is possible. It would be more rational in such a situation to reduce the concentration of the drug, reduce the recommended dose and spray
potatoes already after the germination of weeds. More detailed information regarding crop sustainability is provided by seed potato producers.
