Understand what weeds are, why they survive so successfully, and why weed management is central to profitable crop production.

Weed Biology and Ecology — reproduction, seed bank dynamics, competitive interactions, and allelopathy in weed populations.

Weed Classification and Identification — grasses, broadleaves, sedges, and parasitic weeds with key identification features.

Cultural and Mechanical Weed Management — crop rotation, stale seedbed technique, hand weeding, and tillage-based weed control methods.

Chemical Weed Control — Herbicide Classification covering pre/post-emergence timing, contact vs systemic action, and selectivity principles.

Herbicide Selectivity and Mode of Action — ALS inhibitors, ACCase inhibitors, PSII inhibitors, EPSPS inhibitors, and auxin mimics.

Herbicide Resistance — mechanisms of resistance, resistant weed populations worldwide and in India, and management strategies.

Learn how cultural, mechanical, chemical, biological, and preventive methods are combined in an integrated weed-management system.
