CROP: Potato
No current practice in potato production provides more benefits than soil fumigation. Soil fumigation with Strike allows plant roots to develop in an environment where nematodes and other soil borne diseases are managed.

Less Potato Seed Needed
A potato is unique in that daughter tubers will grow as big as they have room to grow. A larger tuber set will require more spacing (typically 14” as compared to 10” between). This can lead to a 20% reduction in seed needed, which equates to roughly $100/acre savings by growing healthy plants.
