MANA announces online resource for white mold information & prevention

MANA Crop Protection has developed a new online resource for dry bean growers to seek information and disease prevention strategies on white mold. The website,, allows growers to enroll for Dry Bean White Mold Weekly Updates.

Growers who access the online resource and subscribe to Dry Bean White Mold Weekly Updates can expect to receive reports beginning in early May and continuing through June. Weekly reports from MANA Crop Protection will be sent to growers via email delivery.

Dave Feist, Project Development Leader for MANA Crop Protection, says the resource was created to deliver highly relevant information to dry bean growers seeking disease management insight behind the complexities of white mold.

“Growers who have dry beans in high alert areas for white mold are encouraged to utilize this resource to increase their knowledge of the disease’s profile and proliferation trends, ways to minimize spreading between fields, evaluate its economic impact on yields, and learn preventative approaches to minimize risk. Also, growers can opt to receive a weekly email update which will give additional insights during the season along with regional planting progress and outbreak reports.”

To encourage participation, growers who sign up for the Dry Bean White Mold Weekly Updates will be registered to qualify for a Grand Prize drawing for a $1,000 certificate, or one of two Runner-Up Prize drawings for a $500 certificate at Acme Tools®. Random selection for each prize will occur at the conclusion of the program with winners notified by June 30, 2012.

The disease typically shows up in early summer about the time dry bean plants begin to bloom. It is known to thrive in cool temperatures alongside moisture-rich soil conditions caused by heavy spring rains. Hosted by a lush crop canopy, the environment can become “a perfect storm” for the disease to infect a field.

Dr. Sam Markell, Extension Plant Pathologist at North Dakota State University (NDSU) in Fargo, says a grower only has to look back as far as the 2009 to see this economic impact play out. “Temperatures were cool to moderate into July of that year and moisture was optimum for a white mold outbreak that covered much of the North Central region. Some North Dakota growers lost entire fields.”

Markell adds that the 2009 epidemic was an eye-opening experience for many, and with a repeat of high white mold pressure in 2010, he believes white mold should be on every grower’s radar. He continues by saying that there is still plenty of white mold inoculum in the soil, making it necessary to take precautions to minimize the disease risk in 2012.
