Evaluation of Nemastrike for Control of Nematodes in NC Cotton

Nematodes have become more problematic in NC cotton over the past few years, primarily due to the loss of aldicarb.  Growers have adopted in-furrow liquids as their primary control measures for thrips, and many are no longer equipped to apply granular insecticides even as aldicarb returned to the marketplace.  Cultivar tolerance to nematodes are primarily focused on root-knot nematodes, however, several other species also affect cotton.  Velum Total has been evaluated as a control measure but can only be used by growers who are equipped to apply infurrow liquids.  Nemastrike seed treatment was commercially released in 2018 and is touted to provide broad spectrum control of nematodes.  The objectives of this research were to evaluate Nemastrike activity on multiple nematode species, and to evaluate the effects this seed treatment may have on yield in fields with a problematic history of nematode pressure.
