Pityophthorus juglandis, a newly discovered invasive pest species in eastern Tennessee, threatens to significantly diminish populations of Juglans nigra (black walnut) throughout its native range. Two insecticides (imidacloprid, dinotefuran) and one fungicide (potassium phosphite) are under evaluation as potential chemical control agents for P. juglandis and the thousand canker disease.
