Technical Abstract: A root-knot nematode resistant bell pepper cultivar, Charleston Belle (Capsicum annuum), and metam sodium were evaluated for managing southern root-knot nematode (Meloidogyne incognita) in fall-cropped cucumber (Cucumis sativus). 'Charleston Belle' and its susceptible recurrent parent, 'Keystone Resistant Giant', were planted as spring crops at Blackville, SC and Tifton, GA. 'Charleston Belle' exhibited high resistance and 'Keystone Resistant Giant' was susceptible. After termination of the bell pepper crop, one-half of the plots were treated with metam sodium delivered through the drip irrigation system. Cucumber grown after 'Charleston Belle' x metam sodium had the lowest root gall severity and lowest nematode reproduction. Root gall severity and nematode reproduction were highest for cucumber grown in plots following 'Keystone Resistant Giant' x control. Cucumber yields and numbers were highest for cucumber grown following metam sodium with either cultivar.
