Weeds are ubiquitous in nature and invade both crop and non-crop lands. When present in crop fields, weeds compete with the crops for nutrients, soil moisture, solar radiation and space; hence reduce their productivity and quality. But, they have been the most underrated crop pests despite the fact[r]
