Methods of Weed Control
Weeding: the removal of unwanted plants (weeds) growing along with desired crop from the field is called weeding. The most common weeds are Amaranthus (chaulai), Convolvus (hiren khuri), grass etc. Weeds are required to be removed because they compete with the crop plants for their basic needs like water, sunlight , nutrients. Weeds often grow faster than the main crop. The process of removing weeds from the field is done by two ways:
1. Manually: by pulling out the weeds with the help of trowel (khurpa).
2. Use of weedicides: certain chemicals are sprayed in the filed with the help of a sprayer. Some common weedicides are 2,4 D, Dalapon, Metachlor and Siniazine. These are poisonous chemicals. Therefore grains as well as other crops must be washed thoroughly before use. During spraying, farmer must cover his nose and mouth.
