According to experts, the most suitable period for processing is the time before the emergence of seedlings, as well as after 3 - 4 weeks from the moment of their emergence. Treatment with the drug, as a rule, is carried out once or twice. Further, we will consider the ways of using "Lazurit" on the example of potatoes, the most often cultivated crop.

A single application of the drug Lazurite for weeds is carried out by spraying the soil, in an amount of 700 g to 1.4 kg per hectare. When the tubers are planted at the optimum depth, the buried sprouts will not be affected by the herbicide. Processing is carried out, if possible, on a windless day, not forgetting to moisten and loosen the soil in advance. These actions will improve the effectiveness of the drug.

In case of double treatment, the amount of the drug applied for the first time should be from 500 g to 1 kg per hectare. The second time the soil is treated with an even smaller amount of herbicide - no more than 300 g per hectare.

Important to rememberthat the appearance of 5 cm potato shoots on more than three quarters of the cultivated area is an indicator that it is no longer possible to apply the drug.

Instructions for the use of Lazurite for weeds contains the minimum and maximum dosage of the drug, which depend on the quality of the soil. For example, for heavy soils that do not differ in air permeability and moisture capacity, the dosage of the drug is increased to the maximum. And for light and loose soil, on the contrary, they are limited to the minimum amount of the applied preparation.

In addition, if the content of nutrients in the soil is less than 1%, this drug is not recommended at all.

The working solution, as already noted, is prepared by mixing the drug with water. To begin with, the drug is diluted in a small amount of water, ensuring its maximum dissolution, and then the water is added to the required volume. For example, a 20-gram sachet of a substance is first dissolved in 1 liter of water, and then the volume of the solution is brought to 6 liters. A solution of this concentration can be used for the first soil treatment, when the seedlings are not yet visible. If it is necessary to reapply the drug, its dosage should be 20 grams of dry matter per 20 liters of water. It should be remembered that the maximum concentration is permissible in the amount of 0.5% of the active substance. The prepared solution is not stored.

When carrying out treatment with herbicides, it is necessary to observe safety measures. Despite the fact that the drug is less toxic than other herbicides, when working with it, it is important to protect the skin of the hands, face, and respiratory organs. Therefore, it is necessary to carry out treatments, especially by spraying, with gloves, a mask, glasses, as well as wearing a robe or apron. Manual work on the site is possible no earlier than a week after its processing.

The possibility of contact of the drug with food products, as well as animal feed, should not be allowed.
