Abstract
A survey of 103 soybean fields in five north-central Florida counties was conducted to determine the incidence of Meloidogyne species and grower practices used to manage these nematodes. All fields sampled were infested with Meloidogyne spp. The most prevalent species was M. incognita (Kofoid and White) Chitwood found in 70% of the soybean fields, followed by M. javanica (Trueb) Chitwood in 24% and M. arenaria (Neal) Chitwood in 6%. Management practices for the Meloidogyne spp. in descending order of usage were resistant cultivars, crop rotation, and nematicides. The survey confirmed the potential threat of M. javanica and M. arenaria to this relatively new soybean production area of Florida.
