Dry beans are sensitive to weed competition. Weed growth reduces bean yields by competing for light, moisture, and nutrients. High weed populations also are likely to cause a buildup of disease and/or insect problems that may affect bean growth, development, and marketability. Weeds also increase harvest losses, reduce bean quality, and make seed cleaning more difficult and expensive.

In some seed-producing regions, contracting seed companies or seed associations have secured special local needs (SLN) labels for members. These labels may not be listed here because the authors of this handbook wish to honor the third-party ownership of these labels and their restricted use. SLNs for Syngenta products are only found on the website farmassist.com , therefore we have included specific directions in the text of each section on how to access these labels, or we have at least referenced other sections where that information is available.
