What is a typical nematode management approach in turf?

• A. Use labeled nematicides only when needed, improve drainage and turf vigor, and consider resistant cultivars or biological options when labeled
• B. Use any available pesticide anytime
• C. Apply broad-spectrum insecticides regularly
• D. Ignore drainage and rely on mowing

Answer: (B)

Managing nematodes in turf relies on an integrated approach that combines cultural practices with targeted, labeled control options and, when possible, resistant cultivars or biological tools. The idea is to reduce nematode pressure while keeping the stand healthy and resilient. Start with monitoring and thresholds to decide if treatment is warranted. Use nematicides only if products labeled for turf nematodes are appropriate and apply them according to the label. Timing is important—products must reach the root zone and are most effective when irrigation and application timing align with nematode activity. After a treatment, rotate chemical modes of action to minimize resistance and follow all label directions. Cultural practices play a big role. Improving drainage and avoiding prolonged soil saturation reduce stress on roots and can lessen nematode damage. Maintaining turf vigor through proper fertility, irrigation management, aeration, and appropriate mowing height helps roots cope with nematode feeding and recover more quickly. Consider resistant cultivars or biological options when available and labeled. Plant materials that resist nematode feeding or use beneficial organisms designed to suppress nematodes can provide ongoing suppression with fewer non-target impacts. Why not just spray anytime or rely on broad, non-targeted controls? Using pesticides whenever available can waste resources, harm beneficial organisms, and promote resistance. Broad-spectrum insecticides and improper timing often fail to address nematodes effectively and can worsen turf problems. Ignoring drainage and relying on mowing alone does not change the root-zone conditions that drive nematode damage.
