Host resistance and metam sodium for managing root-knot nematodes in a pepper-cucumber rotation
HortScience 40 (7), 2080-2082
Abstract: Root-knot nematode-resistant 'Charleston Belle' bell pepper (Capsicum annuum L. var. annuum) and metam sodium treatment were evaluated for managing the southern root-knot nematode [Meloidogyne incognita (Chitwood) Kofoid and White] in fall-cropped cucumber (Cucumis sativus L.). 'Charleston Belle' and its susceptible recurrent parent, 'Keystone Resistant Giant', were planted as spring crops at Blackville, S.C., and Tifton, Ga. 'Charleston Belle' exhibited high resistance and 'Keystone Resistant Giant' was susceptible at both locations. After termination of the bell pepper crop, one-half of the plots were treated with metam sodium delivered through the drip irrigation system. Cucumber yields and numbers of fruit were highest for cucumber grown in plots treated with metam sodium following either 'Charleston Belle' or 'Keystone Resistant Giant'; however, root gall severity and numbers of M. incognita eggs in the roots were lowest for cucumber grown in plots treated with metam sodium following 'Charleston Belle'. Conversely, root gall severity and nematode reproduction were highest for cucumber grown in plots following 'Keystone Resistant Giant' without metam sodium treatment. Application of metam sodium through the drip irrigation system following a spring crop of root-knot nematode-resistant bell pepper should reduce severity of root galling and reproduction of M. incognita as well as increase fruit yield of fall-cropped cucumber.
