Every year, gardeners and gardeners are confronted with the fact that, in areas other than the crops planted by them, all kinds of weeds begin to grow, taking nutrients from cultivated plants. For weed control, herbicides were invented, one of which - the drug "Zenkor" - will be discussed in this article.
Did you know? Herbicide means "kills the grass", from the Latin. herba - grass, caedo - I kill.
Active ingredient and preparative form
"Zenkor" is produced in the form of water-soluble granules, the active ingredient of which is metribuzin (700 g / kg).
The scope and mechanism of action of the drug
Herbicide "Zenkor" has a systemic selective effect, it is used in the pre- and post-emergence period of weeds growing on plantings of tomatoes, potatoes, alfalfa, essential oil crops. The drug penetrates into weeds, suppressing the processes of photosynthesis.
It turns out that not every weed that we find in the garden is harmful. For example, honey is made of dandelions, nettle is able to heal wounds, and wheat grass is used for problems of the genitourinary system.
Herbicide Benefits
The drug has several important advantages:
- extensive range of action - effective on grass weeds and on annual broadleaf;
- herbicidal effect is manifested for several weeks after application;
- compatible with many pesticides;
- protects crops about 6-8 weeks;
Important! To improve the effectiveness of the drug sprayed soil should be slightly wet.
- there is no resistance or habituation of weeds to this tool;
- effective in different soil and climatic areas;
- applied both before and after the emergence of weeds and crops.
How to use: method of application and consumption rates
When using the herbicide "Zenkor" it is recommended to follow the instructions for use exactly. The soil before spraying means must be loosened. Seedless tomatoes sprayed with a solution after the formation of 2-4 leaves. For seedlings tomatoes sprayed the soil before planting seedlings in the ground. 7 g of the drug is diluted in 5 liters of water, this amount is enough for processing 1 hundred square meters of land.
Important! The drug "Zenkor" can not be used in greenhouses.The use of "Zenkora" on potatoes is also carried out by spraying the soil, but before the crop emerges. For the treatment of 1 hundred, it is necessary to dissolve 5-15 g of the drug in 5 l of water. Soybean is processed similarly to potatoes, consumption of 0.5-0.7 kg / ha. The second year alfalfa is sprayed until the culture grows, the consumption is 0.75-1 kg / ha.
Compatibility with other pesticides
Although Zenkor is compatible with many pesticides, it is necessary to check for chemical compatibility before mixing. It is advisable to avoid mixing the dry ingredients without first diluting them with water.
Did you know? In the forests of the Amazon live living "herbicides" - lemon ants. The acid they exterminate destroys all plants except Duroia hirsute. Thus, the "devil's gardens" appear - tracts of forest with only one type of tree.
Toxicity
Herbicide "Zenkor" does not affect the yield of cultivated plants. Some phytotoxicity signs can be observed on individual varieties.
Term and storage conditions
Keep 2 years from the date of production in a place protected from children.
