  2. Methods of Weed Control

  3. Integrated Weed Management (IWM) • Definition: combination of multiple management methods to reduce weed population to an acceptable level while preserving the quality of existing habitat, water, and other natural resources. • Involves 2 critical elements: - using multiple control tactics (cultural, mechanical, biological, and chemical control methods). - integrating a knowledge of weed biology and ecology into the management system.

  4. IWM - Rice

  5. IWM - Maize

  6. IWM - Sugarcane

  7. Can develop a long-term weed management plan, that considers all available management control techniques to control weeds. Likely to hinder the adaptation of weeds to any single control tactic, i.e. chemical control-herbicide resistance. IWM takes a common-sense approach to weed control (helps reduce hazards to people, animals and the environment). IWM works well for agricultural, home, garden and workplace environments. Advantages of IWM*

  8. Advantages of IWM cont… • Avoid unknown problems in the future i.e. some biological agent may become invasive spp., insect may mutate and change their diet attack other crops and plants; mechanical will reduce soil nourishment and cause erosion; water scarcity is a major issue nowadays. • Consists of a series of evaluations, decisions, and control practices which focus on economical and effective control of weed with consideration of ecological conservation. • Most important, IWM helps decrease herbicide use.

  9. Principle of IWM: “THE RIGHT COMBINATION OF DIFFERENT WEED CONTROL METHODS FOR THE RIGHT CROP & ENVIRONMENT AT THE RIGHT TIME”

  10. Future weed control - the super IWM???
