CDFA Interception Records for Pratylenchus coffeae in
California (Courtesy of J. Chitambar, CDFA):
1952 – 1972: Detection of P. coffeae within California is
summarized in Siddiqui, Sher, and French (1973). The nematode was found in
association with ornamentals, strawberry, cherry, and raspberry plants in 175
Nursery (land or greenhouses), 22 Urban (residential properties, golf
courses, parks), and 1 Commercial (cultivated fields and orchards)
samples collected throughout the State.
Siddiqui, Sher and French (1973) obtained much of their information from UC
Berkeley, UC Riverside and UC Davis nematode distribution records, as well as
identificaton records maintained by certain County Agricultural Commissioner
offices and the CDFA Nematology Laboratory.
1973 – 1999: P. coffeae was detected in 223 Quarantine
samples (originating outside California), 32 Nursery samples (field-grown
or greenhouses), 2 Commercial samples (cultivated fields and orchards),
and 27 Dooryard/residential samples.
