For each owner of a personal plot, saving the crop from pests and adverse weather conditions is the main task of the season. Various pesticides - herbicides come to the aid of agriculture. Some of their species are universal, successfully used for a wide range of weeds, others - selective action. One of them will be discussed.
Description of the drug
The herbicide is called "Lapis lazuli". Its main purpose is the destruction of annual weeds, which usually grow between crops of potatoes and tomatoes. The main object of destruction by the drug is euphorbia, sow thistle, thistle, bluegrass and other annual cereals and dicotyledons. Due to the ability to penetrate into plants not only through the root system, but also leaves, the Lapis lazuli herbicide allows complex action on weeds, well clearing areas from them with cultivated crops. Another plus of the drug is the duration of exposure. This means that after one spraying, green pests, having died, do not bother with their new appearance for a long time. In other words, the Lapis lazuli herbicide is a wide range agent, having a devastating effect on harmful cultures both before their emergence and after. The amount of chemical can be dosed depending on the degree of soil contamination and the size of farmland.
Active substance and control mechanisms
Lazurit herbicide is a powdery mass. The main active ingredient is metribuzin. Its concentration is quite strong - 700 grams per 1 kg of the drug. For soil treatment, the product should be diluted with water. Once in the ground, the solution is absorbed by the weeds through the roots, as well as by spraying seedlings through the leaves. It destroys plants even before germination,
during the growing season. If sow thistle, tramp and other pests managed to fill the area, then the chemical dealt with them in about 2 weeks. Lapis lazuli, like other selective herbicides, protects crop crops for a period of 30 to 60 days. The duration of the drug depends primarily on the weather. Naturally, if it is dry, the product in the soil and on the surface of the leaves lasts longer (2 months). With increased humidity and dampness, repeated treatment will be required more often (after a month). Secondly, on the degree of contamination of the land and those specific types of weeds that occupied it.
Spectrum of exposure and instructions for use
At Lazurit, like other herbicides, the price is not too high. It ranges from 50 to 120 rubles per bag weighing 10 kg (powder) or concentrated liquid (canisters of 5 liters). Therefore, the drug is beneficial for use both for large farms, for small plots. Shelf life is 3 years. The most sensitive to it are
weeds such as quinoa, chicken millet, cornflower, icteric, colza, nightshade, datura, highlander, purslane, chamomile and many others. Of course, most of these herbs are considered medicinal, successfully used in pharmaceuticals. But in the fields and gardens they do great harm, and this should be reckoned with. As for the use of "Lazurite" - it can be combined with other herbicides, in turn dissolving them in containers for spraying. Consumption rates depend on which vegetable crop is saved from weeds, and range from half a kilogram to one and a half per hectare for potatoes at different stages of germination and growth; from 1 kg 400 g to 0.5 kg per hectare for tomatoes; from 0.5 kg to whole for soy and corn.
The Lazurit weed remedy is produced by the Russian company August.
