Application of Lazurite from weeds on potatoes

Potatoes are the most popular vegetable crop grown in vegetable gardens around the world. Being a fairly unpretentious plant, it is quite suitable for mass planting in our country. However, we still have to deal with one of the problems – these are weeds: you won’t get a good crop on a neglected field. The most popular Weed Control Method is chemicals. Lapis lazuli from weeds on potatoes – what are its advantages?

Principle of action

The active ingredient of the drug is metribuzin. The chemical aims to destroy weeds through their seedlings, roots and foliage. This is a fundamental difference from mechanical processing, in which only the surface layer of weeds is removed, and the root system remains intact. The first rain will again bring the "pests" into activity. Poison after getting into the soil acts directly on the root, and also blocks the process of photosynthesis, depriving the weed grass of sunlight. It begins to fade and gradually dries out completely, giving the potato free breath. Many species are sensitive to the Lazurite weed remedy, such as dicotyledonous annuals and cereals (chamomile, quinoa, dandelion, ragweed, sow thistle), as well as perennial herbs. Used by gardeners to protect potatoes and tomatoes from weeds by controlling them.The farmer must remember that the preparation helps to clean the field, but is not fertilizer, and therefore in the empty soil with a low humus content it will not help the cultivation process.

One of the main advantages of this herbicide is its safety for the crop itself with an effective destructive impact on the weed. However, for the correct action of the drug, the user must clearly follow the instructions.

Operating rules

The herbicide is a chemical agent, and therefore it should be handled very carefully, following all points. If Lazurite is used correctly, neither people nor plants will suffer from weeds.
  1. The time when you should start using the drug is before potato seedlings, before they rise 5 cm above the ground (about 75% of seedlings ) As the culture grows, its protection against the chemical weakens - that is why timely treatment is so important.
  2. You can’t loosen the soil after spraying so that the drug does not move to the lower layers, where its effect is ineffective.
  3. So that heavy rainfall does not wash the drug out of the ground, seedlings should be hung. Drought also negatively affects the action of metribuzin.
  4. A little irrigation is still necessary - so that the particles of the substance spread in the soil.
  5. There is an established dosage of the diluted spray preparation, which must be strictly adhered to. According to the instructions for potatoes, it is 250-300 liters per 1 ha.During the first treatment, 10 g of substance is consumed per 3 l of water per 100 m2. At the second stage, 10 g of the drug and 9 l of water are added to the above ratio. The maximum concentration of the working solution should not be higher than 0.5%.
Two methods of using the herbicide differ in the number of stages of spraying procedures. Two-step described above: one-time involves the consumption of funds from 0.8 to 17 kg per ha. Care must be taken to ensure that the poison does not get into the vegetable crop, so it should be hidden deep in the ground. Moisten the soil and wait for the ridges to settle.

Application Summary

When the potato tops close, it will be too late for the spread of annual weeds. In addition to combating them, the tool helps to prevent a disease such as late blight, which negatively affects the yield and preservation of the plant. On peat and bog soils, the treatment is carried out after germination.
