April 18, 2023

MSU Extension Sweet Potato Specialist Lorin Harvey calls into the Crop Doctors’ Podcast studio in Stoneville to discuss the Guava root-knot nematode and the potential problems for Mississippi sweet potato. The guava root-knot nematode is similar to the southern root-knot nematode and is considered the most damaging root-knot species in the world because of its wide host range, aggressiveness, and ability to overcome the root-k not resistance developed for many crops. Lorin, Jason, and Tom talk about the origins of the guava root-knot nematode, how it can be detected, and suggestions for management.
