We all know and believe that bad things accompany each and every good thing.
Likewise, weeds compete with the mainstream crop in every area. Let’s understand some facts about these unwanted plants, called weeds.
What is ‘Weed’?
Weed. The term stands for plants growing in a wrong or undesired place. Weeds, generally, act as competitors for the main crop or plants for sunlight, nutrients from ground and space. These factors mainly affect the growth of the desired flora.
Taxonomically, there is no term called weed in botany as a plant which is treated as a weed in one context is not weed in a situation where it is grown as the main crop. The term weed is also used for plants that reproduce at a large scale within a small period.
Eradication of weed is essential in case of agriculture or other human controlled setups like farm fields, gardens, lawns or parks. Methods of removing the weeds vary depending on the personal choice, weather conditions and other factors.
Weed control techniques can be broadly classified into five categories, irrespective of the area or where from the weeds are to be removed.
