The N.C. Department of Agriculture and Consumer Services’ Nematode Assay Lab is warning North Carolina growers to expect turnaround times of 15 weeks or longer for routine (predictive) nematode samples submitted this year. Samples submitted for diagnostic testing, including molecular diagnosis of guava root-knot nematode species, will be given priority and those results should be available in around five working days. Currently, there are around 15,400 samples waiting analysis.
