Abstract: A new disease in cucumber, brought about by a distinct forma specialis, Fusarium oxysporum f.sp. radicis-cucumerinum that causes a stem and root rot, was evident in the Ahituv region of Israel in the winter and spring of 2002 and 2003. The identity of the pathogen was verified by pathogenicity and VCG tests. The first record of this disease in Israel was in 1998 at Hatzav, with subsequent appearance at additional sites. This pathogen produces masses of aerial macroconidia on the plant stem, which have the potential of spreading the pathogen. Means to reduce the inoculum and disease incidence were examined. Application of 0.1 g per plant of the fungicide Bavistin at 2-week intervals, starting 7 days after planting, reduced disease incidence. In three greenhouse experiments applying structure solarization and reaching maximal temperatures of 50-70° C, inoculum reduction was 46-97% after 22 to 27 days of solarization. Dipping contaminated support strings in 1% sodium hypochlorite eradicated the pathogen. The disease was totally controlled when the resistant rootstock 148-TZ was used. It is concluded that a holistic approach to control that integrates sanitation, grafting, fungicides and crop rotation, is necessary in order to achieve satisfactory reduction of inoculum and disease.
