What’s Hot Now?
by Randy Swett
What are those strange looking bumps on the roots of my tomato plants?
Root knot nematodes are small (0.01-1.0 inch) galls that form on tomato roots. These galls can interfere with the flow of water and nutrients to the plant which can make them less vigorous and yellowed when compared to healthy plants. Control by using nematode resistant tomato varieties and rotating with non-host crops like black eyed peas which are resistant to some root knot species.
See the UC IPM guidelines on Root Knot Nematodes for more information.
