Report shows need for diversity in soybean cyst nematode resistant varieties
A report analyzing nearly 20 years of field data collected by Iowa State University on soybean cyst nematodes shows the tiny, parasitic roundworm has continued to adapt to the industry’s most popular resistant variety. The analysis looked at PI 88788, a type of soybean cyst nematode resistance in seed varieties, and found the ability for the nematodes to reproduce on PI 88788 soybeans increased approximately 2%, annually, from 2001 through 2023. If the trend continues, varieties with PI 88788 resistance would have just 40% control of soybean cyst nematode by 2030. This could lead ...
