NEMATOLOGY SECTION
Compiled by Robert P. Esser, Ph.D.
A total of 2,972 samples were processed in January and February. Details are shown below:
Multistate Certification Identification for National and (Invertebrate) 2
International Export1721 Plant Problem 126
California Certification 507 Out of State Survey, via Premovement 38
Florida Interceptions27
Site or Pit Approval 69 Instate Survey, Random165

Asparagus virgatus (slender asparagus) -- The following nematodes (Aphelenchoides sp., Criconema sulcatum, Henicriconemoides minutus, Hemicycliophora floridensis, Hoplolaimus tylenchiformis, Longidorus sp., and Xenocriconemella macrodora) detected in Umitilla, Lake County (25 January 94, W. Smith, N94-00127) and Barberville, Volusia County (1 February 1994, J. Beckwith, N94-00148). FIRST TIME IN SOIL ASSOCIATED WITH THIS PLANT SPECIES.
Citrus sp. -- Xiphinema tarjanense, a dagger nematode, detected in Haines City, Polk County (21 January 1994, M. F. Fuller, N94-00101). FIRST TIME IN SOIL ASSOCIATED WITH A SPECIES OF CITRUS. Originally described and associated with an oak tree in Winter Haven, Florida.
Citrus limon (lemon) -- Rotylenchulus reniformis, reniform nematode, in Miami, Dade County (21 December 1994, C. Ferguson and T. Perez, N93-1699). FIRST TIME IN SOIL ASSOCIATED WITH THIS SPECIES.
Podocarpus gracilior (fern podocarpus) -- Xiphinema krugi, a dagger nematode, in Ft. Lauderdale, Broward County (21 December 1994, B. Coy, N93-1698). FIRST TIME IN SOIL ASSOCIATED WITH THIS SPECIES.
NEMATODE NOTE 124: Nematodes are the second largest cause of yield loss in cotton. (Seedling diseases account for the largest loss of cotton, with 836,309 bales lost in 1992.) There were over 13 million acres of cotton planted in 16 states in the United States in 1993, valued at 6 billion dollars. Mississippi has the largest cotton acreage at 1,030,000 acres. Florida grows ca. 53,000 acres of cotton.
In 1992, plant parasitic nematodes accounted for a conservative estimated yield loss of 528,000 bales of cotton valued at 184,951,200 dollars. The yield loss of bales estimated in 1982 was much less (161,000 bales); however, the 1982 figure was considered low because damage loss by nematodes was erroneously attributed to soil infertility, pH problems, or "weak" fields.
