Alfalfa planting.

Asked July 18, 2014, 10:37 AM EDT

Do you have any experience planting alfalfa on ground with high SCN egg counts? Egg numbers range from 20000-33000 eggs/100cc of soil.All the information i have been able to find so far says it would not be a problem,but SCN issues are pretty new in this area.Any info would be very helpfull. Thank you,Dave Olson Fosston Tri Coop.

Sorry for the slow response; I've been on vacation for the last 10 days.
I don't have experience with planting alfalfa after soybean in a field infested with SCN. Alfalfa is an alternate host to SCN; therfore, alfalfa is not a good rotational crop to reduce SCN numbers. SCN will reproduce in alfalfa, but it is generally not a problem and should not reduce yield.
I've referred you to Seth Naive in Minnesota, who may have more experience with this in your area.
