The drug helps to quickly get rid of annual dicotyledonous and cereal species of weeds - foxtail, common dope, field mustard, cornflower, quinoa, ragweed and schirin.

Herbicide Lapis Lazuli works selectively
Lapis lazuli - tablets, powder for dissolution in water and emulsion, which include metribuzin - an active substance that is characterized by a fast action. The powder is packaged in sachets weighing 20 g, the emulsion in plastic containers of 5 liters.
When spraying vegetable beds, metribuzin penetrates into the stems and leaves of the weed, getting into its root system. The herbicide inhibits photosynthesis in the weed plant, impairs the absorption of moisture, nutrients and oxygen saturation, as a result of which it dies.
The instruction for the use of Lazurite from weeds emphasizes that concentrated metribuzin has a detrimental effect not only on weeds, but also on soil and vegetables. Therefore, the herbicide must be diluted with water before use.
Features and benefits of the tool
Lapis lazuli from weeds on potatoes has several advantages over other herbicides. The action of the drug begins immediately after spraying vegetable beds - after 6-7 days weeds begin to dry out gradually, and after 10-14 days they completely disappear from the garden.
The main advantages of Lazurite:
- The herbicide is completely water soluble. Thanks to this, it quickly penetrates the stems, leaves and other parts of the plant.
- A properly prepared solution does not accumulate in soil and vegetables. It does not harm the crop and the environment.
- The drug acts not only on adult weeds, but also on their seedlings, stopping their further growth.
- According to the manufacturer, Lazurite not only destroys weeds, but also strengthens the immunity of potato bushes to late blight and negative weather conditions.
- Lapis lazuli is safe for the ecological environment. It has no toxic effect on bees and is moderately toxic to fish.
- The herbicide has an affordable cost (about 90-100 rubles per 20 g), which makes it possible to use it on large household plots or agricultural fields.
The action of the herbicide Lazurite is aimed at combating more than 50 varieties of weeds, including ragweed, wild oat, meadow chamomile, bristle grass, blue cornflower, shepherd's purse.
Instructions for the use of Lazurite
How to apply lapis lazuli against weeds, as well as the frequency of using the herbicide depends on the degree of their growth.
Preparation of working solution:
- fill the sprayer reservoir with ½ the required volume of liquid;
- fill in the required amount of the drug;
- mix the liquid well so that the herbicide particles are completely dissolved;
- add clean water to the tank to the required volume specified in the instructions.
With a small amount of weeds, it is enough to carry out one treatment of the beds.To do this, prepare a solution of 10 g of the drug and 3 liters of cool water. Lapis lazuli herbicide for seedlings potatoes used for spraying in a volume of 1.5 liters per 1 m².
In the case of extensive weed growth, at least two treatments of vegetable beds are carried out. For this, a concentrated solution is used, prepared from 20 g of the drug and 18 liters of water. The solution should be used only after the height of potato shoots reaches 5-6 cm. The consumption of the preparation will be 6 liters per 5 m².
There are highlighted cases in which the use of Lazurite is not allowed. This is a prolonged drought, sudden changes in air temperature, and recent plant diseases. Herbicide treatment is not carried out for early varieties of vegetable crops and with a minimum amount of weeds.
Features of the solution
In order for the treatment of the beds with Lapis Lazuli to bring the expected result, several important nuances of using the herbicide must be taken into account.
- Processing vegetables with a solution should be carried out in warm, dry and calm weather. The air temperature should warm up to + 18-24 ° С. Precipitation accelerates the penetration of the drug into the soil, reducing its effectiveness.
- Be sure to consider the type and fertility of the soil. For "heavy" soil, you will need the maximum concentration of the drug, for the light less concentrated.
- Before the first spraying, loosen the soil a little and moisten it well, then let it settle slightly.
- After treating weeds in potato beds, you must not loosen the soil. This will cause the drug to penetrate the potato tubers.
- In order for the herbicide not to harm the potato tubers, deepen them into the soil by about 10-15 cm.
- For early potato varieties, a solution with a minimum concentration of Lazurite is used.
- The duration of the action of the herbicide depends on the weather conditions. In warm, dry weather, lapis lazuli remains effective for up to 7-8 weeks.
The prepared solution of Lazurite can be watered with weeds under the root or sprayed with a sprayer.
When treating corn, potato or tomato beds with a herbicide, it must be borne in mind that it does not belong to fertilizers. Even the complete absence of weeds does not guarantee a rich harvest. That is why Lazurite is often combined with other drugs - fertilizers, pesticides, insecticides, acaricides and nematicides. Such combinations will help to eliminate the imbalance of nutrients in the soil, to protect vegetables from many diseases and pests.
