Across the corn belt depending on time of year | Growing continuous corn without rotation is not a preferred agronomic practice. However farmers follow that course of action due to external factors like feeding cattle, dairy operations, high debt load etc. That is the reason for trait failure and maybe rootworm becomes resistant to biocontrol nematodes in these high pressure systems also. Time will tell for sure.
Rootworm should be a minor problem if a farmer is truly using a multi-year, multi-crop rotation and can get by without an insecticide or traits. If so, that farmer will not see much benefit from biocontrol nematodes against rootworm. If the rotation caused wireworm problems, then a farmer might see a return on investment for the cost of the biocontrol nematodes. |
