2015 Herbicides for Weed Control in Snap and Dry Beans

2015 Herbicides for Weed Control in Snap and Dry Beans
Have you had problem weeds slipping through your snap or dry bean weed control program? Have lambsquarters, ragweed, hairy or Eastern black nightshade, nutsedge, etc, been escaping? Herbicide choice and rate, application timing, soil or foliar application, rainfall and temperature near the time of application, soil organic matter, clay/silt content, and moisture, etc. can all affect how well herbicides work. Some bean classes are more sensitive to bean phytotoxicity/damage than others. Some herbicide residues last a long time in soils and there are restrictions on what crops can be planted 8, 10 or 12 months after the application.The 2015 update to the Herbicide for Snap and Dry Bean Weed Control chart includes information on all these factors and will help you choose the best herbicide programs for your fields.

Announcements

Cornell Crop and Pest Management Guidelines Paused

From Cornell IPM:

Highlighting its commitment to quality and long-term sustainability, Cornell Integrated Pest Management's Pesticide Safety Education Program has announced
a pause in production of the 2026 Cornell Crop and Pest Management Guidelines.

Cornell IPM Director Alejandro Calixto said this temporary measure is the result of a comprehensive reimagining process facilitated by Illume Projects of Ithaca, which included end-user interviews, internal surveys and sales data analytics.

"It became clear to us that we cannot continue producing the guidelines and fully restructure them at the same time," Calixto said. "By pausing production, we can dedicate all available resources and time to rebuilding the production process, ensuring that when we re-launch in 2027, the guidelines will reflect a modernized approach built around the grower and other user experience."

A series of annually updated reference manuals produced by Cornell IPM and the College of Agriculture and Life Sciences (CALS), the Cornell Crop and Pest Management Guidelines are widely used by farmers, agronomists, crop consultants and extension educators in New York and throughout the Northeast. They include information about current IPM recommendations, pesticide options, cultural practices, nutrient management, disease, insect and weed identification and resistance-management strategies.

Calixto and Pesticide Safety Education Program Lead Mike Helms will spearhead efforts to restructure the guideline process over the next 12 months, with a goal of launching a more streamlined, user-friendly version in 2027.

Limited copies of the 2025 guidelines remain available for purchase while supplies last through The Cornell Store. The 2026-2027 Greenhouse Guidelines will be available.
