Igniting more soybean growers to actively manage SCN
SCN Profit Checker
You may know SCN is lurking in your fields, but do you know how much it’s costing you? Our new SCN Profit Checker tool tells you. Powered by data collected from 25,000+ university research plots, this tool defines that economic toll, field by field, driving home the need for active SCN management.
SCN Overcoming
Resistance.
It’s similar to the herbicide resistance problem. After 20+ years of farmers using the same source of soybean cyst nematode (SCN) resistance, nature is finding a way around it.
Take the test.
Know your numbers.
Managing SCN involves more than just planting an SCN-resistant variety. You need to know your numbers. Here’s why:
- Nearly all SCN-resistant varieties have the same source of resistance: PI 88788.
- SCN populations are adapting and reproducing on PI 88788 — they’re becoming resistant to the resistance.
- As SCN reproduction increases, yield decreases.

That’s why The SCN Coalition recommends that you work with your advisors to develop a plan to manage SCN:
Test your fields to know your numbers
Rotate resistant varieties
Rotate to non-host crops
Consider using a nematode-protectant seed treatment
More soybean growers are actively managing SCN.
The SCN Coalition conducted a survey of soybean growers in 17 states in 2015 to find out if they knew about weakening SCN resistance and strategies to actively manage SCN. The survey was repeated in 2020 and revealed the projected economic impact of the Coalition is staggering: 6% to 18% more soybean growers are actively managing SCN than in 2015. That’s tens of thousands of growers, millions of acres and hundreds of millions of dollars.
