Pay attention to SCN

soybean cyst nematode management
Long an issue in soybean fields, soybean cyst nematode is still a pest to watch for.

No, we didn’t rerun an old 1990s story about soybean cyst nematode.

This is SCN 2000s – the resistant species. Like weeds, diseases and insects, overuse of a repeated practice will infect and erode your bottom-line soybean profits.

These bad, resistant nematodes are ignoring SCN-resistant (PI 88788) soybean varieties, continuing to reproduce and invade their roots.

Genetic resistance is faltering, and seed companies are currently not offering many alternatives.

If you’ve soil tested and are on top of your SCN numbers in every field, that is impressive. And perhaps you’ve even documented how current SCN-resistant varieties are not reducing SCN populations like they have in the past.

But if you’re in the more popular camp that believes SCN isn’t a yield loss concern – or you use SCN-resistant varieties regularly as a preventive measure without knowing your SCN population numbers – then check out our story.

In an effort to magnify the importance of this yield-stealing, resistant microscopic worm, a new SCN Coalition has been formed to launch a national effort against this pest. The group hopes to repeat the success from 1998, when our magazine helped the first SCN Coalition encourage farmers to incorporate various management practices along with the new SCN-resistant soybean varieties.

This time we focus on SCN as a chronic plant health problem that won’t go away, ever. However, there are critical management practices along with rotation of SCN-resistant varieties and seed treatments that can help keep nematode numbers low so they won’t impact soybeans and your profits.

Stay tuned during the months ahead as we work with the SCN Coalition and partners to dissect this problem and outline state-by-state strategies to reduce losses to SCN.
