Which of the following statements regarding nematodes in turf is not true?

The statement that mid-summer is the best time to assay soil for nematodes is not true. The best time to sample for nematodes is typically during the cooler months of spring or fall when nematode populations are more active, and their effects on turf can be more easily observed. In mid-summer, high temperatures can lead to stress in turf, making it more difficult to distinguish between damage caused by nematodes and other environmental factors.

This highlights the importance of understanding nematode life cycles and seasonal behavior when determining the appropriate time for nematode sampling and management practices. Sampling at the wrong time can lead to inaccurate assessments of nematode populations, resulting in ineffective pest management decisions.
