Nematode Management in Cucurbits (Cucumber, Melons, Squash)

Plant-parasitic nematodes are small microscopic roundworms that live in the soil and attack the roots of plants. Crop production problems induced by nematodes therefore generally occur as a result of root dysfunction; nematodes reduce rooting volume and the efficiency with which roots forage for and use water and nutrients. Many different genera and species of nematodes can be important to crop production in Florida. In many cases a mixed community of plant-parasitic nematodes is present in a field, rather than having a single species occurring alone. Most cucurbits are extremely susceptible to root nematodes and also are often damaged by sting nematodes; other nematodes occasionally cause some losses. Published: March 1999.
