BASF and The SCN Coalition continue soybean cyst nematode education for the third annual SCN Action Month this October

  • Soybean cyst nematodes (SCN) are the No. 1 pests in soybeans
  • Nematodes can cause up to a 30% loss in soybean yield before growers see any symptoms

BASF Agricultural Solutions and The SCN Coalition are joining forces for the third consecutive SCN Action Month to raise awareness of the dangers that soybean cyst nematodes (SCN) pose this October.

This month-long initiative educates growers on why and how to defend against this devastating pest that continues to be the leading cause of soybean yield loss in the United States.

SCN is present in most areas where soybeans are grown and continues to rapidly spread each year with an estimated annual yield loss potential of $1.5 billion. Last year during SCN Action Month, SCN was present in 77% of soil samples BASF received, up 4% from the previous year, and damaging levels of nematodes were found in half of the submitted samples received.

“Many growers aren’t aware of SCN or don’t believe it’s damaging their fields, and identifying it can be difficult as the cysts are about 10% the size of a soybean nodule,” said Nick Tinsley, BASF Technical Field Representative, Seed Treatments.

“Testing your soil during the fall is key to this educational effort. When growers learn their SCN numbers, they can use that information to make a strong preventive management plan for the following year based on real data from their own field.”

There are four steps growers can take to manage SCN: test fields for nematodes, rotate crops, plant a resistant variety and consider a seed treatment. Fortunately, BASF has a seed treatment on the market that protects against both SCN and SDS, a well known problem that often is present with SCN.

ILEVO ® seed treatment is proven to protect against the unpredictability of nematodes, foliar and root rot phases of SDS in soybeans and helps produce strong stands and healthy roots, even in the absence of foliar SDS symptoms.

SCN protection starts at the very beginning by selecting the best seed variety for your field. “Selecting the right variety for the right acre can help reduce SCN pressures in the field,” said Bill Backhaus, BASF Midwest Agronomist.

“Xitavo brand offers varieties that can help protect soybeans from SCN and SDS impact and recently announced the 11 new varieties available for the 2024 growing season, all of which offer native traits that resist SCN.”

BASF and The SCN Coalition encourage growers to get out in their fields this month and test for nematodes to help manage their soybean fields against SCN in the future.
