Weed management tools and their impact on the agro-ecosystem

Weed management tools, including cultural biological, physical and chemical control methods, may have both positive and negative impacts on the agroecosystem. Through proper choices of weed management tools, weed scientists and farmers have the opportunity to contribute to long-term agro-ecosystem sustainability. The choices of weed control options should be those which cause the least environmental perturbations, contribute to the economic well-being of users, and do not result in food quality problems.
