Fusarium wilt of spinach
During the last few years Fusarium wilt of spinach, a disease new to Monterey County and California, has been observed. This disease was first suspected as the cause of severe losses in a 50-acre field adjoining the Salinas River, 4 miles south of Salinas, in 1967. In 1969 it was positively identified on a ranch in the Moss Landing area, where it caused almost complete loss of a summer spinach crop in a 10-acre field. The organism which incites the disease is Fusarium oxysporum f. sp. spinaciae.
