When buying herbicides for weeds, it is very important to make a competent and correct choice in order to exclude the likelihood of destroying not only weeds, but also a useful plant. Before buying, you should carefully study the characteristics of the granular weed killer, otherwise you can cause irreparable harm from its use. Regardless of whether weeds belong to the same family or not, control of them is possible with the use of a certain type of herbicide. It is necessary to carefully study the purpose and use of herbicides.
The effect of herbicides is directly dependent on the externally anatomical differences in plants. Many plants have natural defenses to withstand chemicals because the herbicide cannot penetrate. So, for example, crops such as onions, garlic, in their structure, are equipped with narrow leaves, thanks to which the chemicals drain away without having time to get inside.
The situation is difficult when dealing with weeds such as sow thistle, horsetail, and creeping bitterness. The roots of such cultivated plants go deep into the ground and over time the herbicide has no effect on the bottom, the chemical simply does not reach their roots.
Thanks to modern technology and great breakthroughs in genetic engineering, scientists have deduced a code for cultural sustainability. This code is grafted into plants before sowing, which helps to withstand protection from the harmful effects of chemical poison.
Each herbicide is unique in its principle of action and component composition. The price for them is formed based on these properties. Continuous herbicides are less expensive than selective chemicals because they are less effective on weeds.
The effectiveness of herbicides
Effectiveness when using herbicides is achieved due to the correct dosage, the use of certain methods of application and strictly follow the attached instructions. Chemicals quickly become non-toxic, since when they hit the top layer of the earth, they are exposed to certain factors: wind, ultraviolet rays, etc. Each drug has its own specific time of chemical exposure. In most cases, the decomposition period is 22-24 days. Thanks to irrigation and rain, the herbicides are evenly distributed.
Spring preparation and tillage have a great influence on the efficiency of herbicide use. It is important that after processing (plowing) the earth there are fewer large lumps, as this makes it difficult to evenly distribute the product over the entire surface. Regardless of how good the watering is, poor plowing will prevent the herbicides from fully activating.
After sowing, it is recommended to immediately add the drug to the soil and for a more effective and active action, it is necessary to loosen the top layer of the soil. The effectiveness of herbicide use is achieved in the early stages, when the weeds have 3-7 leaves. All herbicides are activated slowly.
Application of herbicides
Today, there are a large number of herbicides that can help increase yields. The developers made it easier for the gardeners and carried out the sorting of chemicals. Thanks to this, everyone can independently determine which herbicide to use. It is enough to study in detail the instructions for use, methods of application and study the characteristics of the drug. Before use, be sure to study the anatomical properties of weeds, which will allow you to achieve a greater and better effect from the drug used. Remember that each type of herbicide is endowed with its own properties and principle of action!
