Symptoms of SDS are easily recognizable. SDS begins as small, bright, pale green to yellow circular spots on the leaves during late vegetative or early reproductive growth stages.

Sampling helps determine whether current management strategies, such as crop rotation and use of resistant soybean varieties, are effectively reducing nematode numbers. Without testing, populations can build silently, resulting in significant long-term yield losses.

Indigo Ag today announced the commercial launch of the company’s first bionematicide for the U.S. market. Produced as a flowable powder formulation, biotrinsic Z15 is labeled for use on both corn and soybeans, requires no special equipment or training to apply and is adaptable for commercial or on-farm application.

Growing soybean varieties with a source of soybean cyst nematode (SCN) resistance other than PI 88788 can increase yields as a result of better nematode control, says Iowa State University. For improved resistance to SCN, check out this resource when selecting soybean varieties.
