Foliar nematodes are a big problem in the hosta and ornamental plant industry and in hosta gardens
Merit 75 is not labeled for nematodes so we are not sure if it would provide any type of control for this pest. We would recommend contacting your local cooperative extension office to seek further information on the type of nematode that is infesting certain plants on your property. In most situations you can manage nematode populations without any type of chemical control.
