When growing any cultivated plants, you have to devote considerable time to weed control. However, thanks to herbicides - weed killers, the weeding procedure is significantly simplified and shortened. Manufacturers produce a wide range of products for various purposes and prices. To get the expected result, it is important to adhere to the rules for using herbicides.
Advantages and disadvantages
Any preparations intended to destroy weeds are classified as pesticides. Therefore, the means exhibit both advantages and disadvantages.
Benefits of using herbicides:
- the quality of the harvest improves, since when growing some crops it is difficult to separate weeds;
- the care of the beds is simplified and the time for weeding the plots is reduced;
- Thanks to the destruction of weeds, the incidence of diseases in cultivated crops is reduced, and the number of harmful insects is reduced;
- cultivated species receive more nutrients and water due to the absence of weeds.
Despite the advantages of herbicides, we must not forget about the disadvantage of drugs - toxicity. Neglecting protective measures when using products can cause serious poisoning of both humans, animals, and insects. It is also necessary to take into account that the use of certain herbicides must be taken into account when drawing up crop rotation schemes.
What are herbicides in agriculture
On farms it is impossible to do without herbicides when growing crops over large areas. Two types of preparations are used for soil treatment:
- continuous action - are considered the most “aggressive”, since they destroy most plants. They are divided into three subspecies: contact (destroy weeds when they come into contact with green mass), soil (help destroy weed seeds), systemic (affect the root system);
- Selective herbicides have a destructive effect on certain types of weeds. Such means are considered more gentle. However, you need to carefully study the instructions to choose the right drug.
If you choose and apply herbicides correctly, you can get rid of weeds for the season. This is very significant, since in agriculture it is sometimes impossible to manually clear a field of weeds.
Best representatives
Naturally, every farmer strives to use high-quality preparations that cause minimal harm to crop plants. When choosing funds, their cost is essential.
Budget segment
"Glyphos" refers to continuous action pesticides. The product helps get rid of broadleaf and grass-type weeds. It is also possible to destroy vegetation of trees and shrubs. The drug is used in agriculture and forestry. The nuance of use is that the effect does not appear immediately - the death of weeds is observed after 3-4 weeks.
“Tornado” is a systemic drug that helps get rid of climbing plants. The pesticide also destroys weeds, both annual and perennial. It is recommended to apply during the period of initial growth of weeds (April-June). Pros: practicality when used on an industrial scale, safety for humans, maintaining efficiency at temperatures close to zero. Disadvantage - it is not advisable to use in heavy dew or rainy weather.
Expensive drugs
“Lazurit” is a selective herbicide used to protect potato, tomato, and soybean beds. It is recommended to treat the area immediately after the spring snow melts. The downside is toxicity, so when using it is important to protect the skin and respiratory system.
"Ground" is a strong herbicide of continuous action, used at any temperature.Both perennial and annual weeds are destroyed. It is noteworthy that the pesticide destroys not only the above-ground part of the vegetation, but also the root system.
It is necessary to take a responsible approach to the choice of herbicides, since some continuous action preparations do not involve planting cultivated plants in the current season. But most products are not toxic to cultivated plants.
