Weed Management: Principles and Practical approaches

Weeds are probably the most ever-present class of crop pests and are responsible for marked losses in crop yields. Of the total losses caused by pests, weeds have a major share (30%). They reduce the crop yield and deteriorate the quality of produce and hence reduce the market value of the turnout. Therefore, management of weeds in all agro- ecosystems is imperative to sustain our crop productivity and to ensure the food security to the burgeoning population.
