What is Weed?
Weed is the unwanted plants that grow along with the Desirable plants or Crops. Weeds affect the growth of the crop, and they can be very poisonous, may produce burrs or thorns and are also distasteful. Weed also interferes with the management of the desirable plants by contaminating the harvest of the crops. These unwanted plants are even more susceptible and more significant than the profitable crops, and thus they compete with the vegetables for space in the field and also for water and light, and this majorly affects the growth of the plant which is a case of loss for farmers.
Need for Weed Control
As mentioned above as well, weed is dangerous for the growth of the plant, and thus, it is essential to control it. Though the competitive abilities of the pots for nutrients and sunlight vary with conditions and seasons and their effect on the adjacent crop also depends upon the size of the plants. For example, a vigorous and tall-growing weed would have the most pronounced impact as compared to a low growing weed. One way or the other the weeds continue to spoil the growth of your crop and can also be responsible for the diseases and the pests spread to the cultivated plants. Many of the pests initially attack the weeds, but then they move on to the crops which ruin them after a time. To produce a healthy crop, one must take care of the plants.
How to Control Weed
Weed controlling is significant for farmers. Thus there are a lot of methods that are practised by them for weed control, and they can be divided into biological, Chemical, Cultural and Physical processes of weed control.
- Coverings – Farmers usually covers the area of ground to create a hostile environment for weed growth with a specific material and that covering is known as a weed mat. Sometimes several layers of newspaper are also used to cover the crops.
- Manual Removal – In this method of weed control, the gardeners remove the weeds by manually plucking them out, and they make sure that the roots are also pulled out so that it can prevent some to re-sprout.
- Tillage – By Ploughing or tilling the soil, we can uproot the weed and cause them to die. As we are technologically advanced these days and we also have the option for mechanical tilling which can also remove the plants in the growing process only.
- Thermal – One can also use severe heating for removing the weeds, Flame weeding is the similar method in which we give the pots a sudden heat, but the goal of this method is not to burn the plant, but instead it causes a lethal wilting in the plants by denaturing proteins in the weed.
- Stale seedbed – Another method to manually remove the weeds is cultivating the soil and then leaving it like that for a week or more, and in this way, you can hoe the weeds away from the ground at the initial stage only and even before the planting of the desired crop.
- Crop Rotation – This is a prevalent method of weed control in which one can kill weeds by rotating the previous crops with the kind of vegetables which can kill the weeds such as mucuna pruriens.
- Animal Grazing – In this method, people use animals as they can graze the leafy spurges and knapweed and also other toxic weeds sprouted across the crops.
- Organic approaches – there is a combination of various techniques used to control the weed in this case, but one will not at all use the manufactured chemicals if the approach is organic.
- The Herbicides can also do herbicides – Weed control can kill specific targets without harming the desired crops. There are a variety of Herbicides available in the market to control the weed.
- Bradley method – This is a method in which one uses the ecological process more and do much of the work that way only.
There are many more ways which one can use to control the weed and keep their crops healthy.
