Protection from Weeds
- In a field, several undesired plants may naturally grow alongside the crop known as weeds.
- Weeding is the process of eliminating weeds.
- Weeds compete with crop plants for resources like light, space, water, and nutrients, hence weeding is important.
- Some weeds can even prevent harvesting and provide a risk of poisoning both humans and animals.
- Before planting crops, tilling aids in uprooting and eliminating weeds, which may then dry out and combine with the soil.
- The manual removal process occasionally involves physically removing weeds by uprooting or cutting them close to the ground.
- Khurpi assistance is used to do this. In order to remove weeds, a seed drill is also employed.
- The use of weedicides, such as 2,4-D, is another method of controlling weeds.
- With the appropriate amount of water dilution, the weedicides are applied to the fields using a sprayer.
- Weedicides are sprayed on weeds during their vegetative growth, which occurs before they flower and produce seeds.
- During the spraying of these chemicals, the farmers should use a piece of cloth to protect their mouths and nose.
