Chemicals called herbicides are designed to kill excess vegetation. They are selective or continuous action. The first type differs from the second in that it affects some types of plants, while the rest are not damaged. Substances that kill all plants are often used in industrial areas, in deforestation, on railways and highways, under high-voltage lines, in drainage channels, on ponds and lakes.
What are herbicides and their features
They are used to protect plants from harmful weeds, cannabis, coca. You can regulate the strength of the substance by doses and costs. Therefore, the above induced distribution can be considered inaccurate, since several packages of a selective agent will be detrimental to sunflowers, corn, and weeds.
They are also classified according to the purpose of elimination, or rather by plants. The herbicides themselves are intended for weeds. Their variety is arboricides for shrubs and trees, and algicides – for aquatic vegetation.
The method of application is also different – contact and system. It is recommended that you first read reviews about each method and how to choose the tool itself, and then make a purchase. The first type of product does not spread throughout the plant, but acts locally. Only those parts where the means have got are damaged. In the system method, the agent penetrates the weeds or trees through the leaves and roots, and is destroyed.

Substance advantages and disadvantages
When choosing any product, you need to look at its price, instructions for use and understand where it will be used. In a summer cottage, such a tool can be fatal to all vegetation. Therefore, you need to take a poisonous product wisely and determine the proportions correctly.
The main advantages of the products are fast effect, minimal financial costs and effort. After damage to the vegetation, it is enough to simply remove the residues by machine or by hand. The action of the mixture extends for 1-12 months, depending on the initial proportion and the desired effect.
Many soil chemicals are combined with fertilizers, so the gardener doesn't need to do any additional processes. In complex mixtures, there are 2-3 active components that increase selectivity.
Negative indicators include dependence on weather conditions. Herbicides work well in wet soil or in foliar soil in dry weather. If one optimal temperature is maintained, the effectiveness of the product will increase.
All chemicals kill the soil microflora, destroy its structure, reduce the content of organic elements in the soil. An excess of this component increases phytotoxicity. Preparations require special care and storage conditions. Since it is a chemical, it should only be kept in a dry, ventilated area and out of direct sunlight. It can be stored for 2 or more years, and this should be considered before using the product.
