What are weeds? How can we control them?
Solution
Weeds are destructive, undesirable, and durable plants that interfere with the growth of other crops, affecting human activities, agriculture, natural processes, and the national economy. Weeds are plants that are considered undesirable in certain circumstances, that is to say, “plants out of place”. Weed control is essential for agriculture because weeds can reduce yields, increase production costs, interfere with the harvest, and reduce product quality.
Complete answer:
The undesirable plants that grow along with the crops are called weeds. These weeds feed on the nutrients provided to the crops, thereby reducing the nutrient supply to the crops, thereby hindering their growth. The growth of these weeds must be restricted to improve plant growth.
The process of removing weeds is called weeding. To achieve this goal, weedicides are used, which are essentially chemicals specifically designed to destroy weeds. They are sprayed regularly before planting and flowering.
Some important weeding methods are as follows:
Weedicides can be used to control weeds: It is a chemical that is sprayed in the field to kill all available weeds. Weedicides are harmless to crops.
Tillage before sowing also helps to eliminate weeds: tillage can remove weeds. The best time to remove weeds is before flowers and seeds grow.
Manual method of removing weeds includes the use of a hoe tool. It involves regularly pulling or cutting weeds close to the ground.
Manual method: walking through the fields and weeding.
By mechanical means: Use a trowel to traverse the field, fill the space between the rows of crops, and cut / remove weeds.
Note:
The presence of weeds does not necessarily mean that they will damage crops, especially in the early stages of growth, when weeds and crops can grow undisturbed. However, as growth progresses, each of them begins to require more water and nutrients. Estimates show that weeds and crops can coexist in harmony for about three weeks, and then the competition becomes fierce.
