Ecological Weed Management

One of the best philosophies for successful weed management comes from a not-so-old but wise adage: use "many little hammers". The phrase was coined in 1997 by Matt Liebman (Iowa State) and Eric Gallandt (Univ. of Maine). This concept is now widely accepted; it means integrating various tools and tactics to reduce weed seed establishment and dispersal, and limit weed competition. The 'little hammers' approach has framed the basis for ecological weed management.

Examples include: seedbank depletion - mechanical control (cultivation, flaming) - biological control (use of beneficial insects or other organisms) - management based on weed biology - crop diversification - herbicide rotation to avoid resistance - and much more. If you are intrigued by this concept, we recommend reading the original concept paper here [link .pdf]. and browse the resources below to learn about ecological weed management strategies in Oregon vegetable crops.
