The state of Florida in the United States has over 2.5 million ha of turfgrass which brings in
over $10 billion US to the state economy annually. Turfgrass is used on lawns, golf courses,
athletic fields, sod farms, parks, and other venues. Plant-parasitic nematodes are among the
most important pests on turfgrasses in Florida, however effective nematicides are not
available for most turf uses. Fenamiphos has been the most widely used turfgrass nematicide
in the U.S. for over thirty years, but as of 2006 it is longer being manufactured in the U.S.
due to environmental concerns. Over the past eight years a great deal of research effort in
Florida has sought to find innovative ways to manage plant-parasitic nematodes on turfgrass
in the absence of fenamiphos. These efforts include: a) new uses of older nematicides such
as 1,3-dichloropropene, b) development of new nematicides based on chemicals and plantderivatives
such as furfural, mustard-bran, and sodium azide, c) new nematicides based on
novel chemistries, d) biological control organisms such as Pasteuria spp. and Paecilomyces
lilacinus. These efforts have met with varying degrees of success from complete failure to
registration and industry acceptance of commercial products. Experimental results from field
trials with numerous management tactics will be presented and future directions will be
discussed.
