Less N.D. Seed Passes Field Certification
January 15, 2008

According to the North Dakota State Seed Department, less dry bean seed passed field certification this year. The department statistics show that 2,195 acres of dry beans seed passed field inspection in 2007, about 1/3 of the average of the last three years.

Harvested seed still must pass lab testing to be certified.

The number of acres that pass field inspection varies from year to year, says Steve Sebesta, deputy commissioner of the North Dakota State Seed Department.

Disease and weeds (eastern black nightshade) are the usual reasons for failing a field inspection, he says.

The 2007 product year was most similar to 2000-2002 when the average pass rate was approximately 20%, he says. The last four years we have averaged about 55% pass rate with a high of 82% in 2003.

North Dakota certification rules require that seed harvested from edible bean fields be tested for bacterial blight and anthracnose. The dome test for bacterial blight requires two pounds of seed and costs $60. The anthracnose test requires three pounds of seed and costs $70.
