Controlling Root-Knot Nematodes in Vegetable Gardens

A gardener with wilting tomatoes, cucumbers, and cantaloupes showing knotted roots asked for nematode control and resistant varieties.

Control Product

Chitin-based products (e.g., Hi-Yield Nem-i-cide, made from crab shells) suppress nematodes. Till in several weeks before planting.
Available at independent garden centers.

Look for VFN after the variety name (Verticillium, Fusarium, Nematode resistant). Examples:

Ask your garden center what VFN varieties they carry; search online seed catalogs (Johnny's, Territorial, Burpee) for current listings.

Combine chitin amendments with resistant varieties for best results.
