Abstract
Quantitative assays of soil samples from areas heavily infested with M. xenoplax consistently indicate low populations in samples collected after prolonged dry weather. Modifications of Jenkins'' centrifugal-flotation procedure were tested to improve extraction of this nematode from dry field soil. Mixing dry samples from the field in water with a Waring Blendor just prior to extraction, or increase in the sucrose concentration in the flotation procedure, increased the numbers extracted. Best results were obtained when the soil was moistened to 16-24% (vol/wt) 1-7 days before the routine procedure was done.This publication has 1 reference indexed in Scilit:
