Weeds are the plants, which grow where they are not wanted. They grow in the fields where they compete with crops for water, soil nutrients, light and space and thus reduce crop yields.
Harmful Effects: They harbor insect pests and micro-organism. Certain weeds release the inhibitors or poisonous substances into the soil which are harmful to the plants species and other live-stocks.
Weed Control includes the spraying of new generation Weedicide/Herbicide over the weeds (unwanted plants) growing on the land/premises.
