CULTURAL METHODS FOR MANAGING NEMATODES ON VEGETABLES AND ORNAMENTALS

B.B. Westerdahl
The loss or restriction of use of nematicides in recent years has rekindled an interest in the use of cultural practices to manage microscopic roundworms that feed on the roots of vegetables and ornamentals. Although the nematode control obtained through individual cultural practices is likely to be less than that provided by traditional fumigant nematicides, recent developments offer new tools to fine tune the use of cultural practices in vegetable and ornamental cropping systems. The development or selection of cover crop varieties for use against particular nematode species, the use of biofumigation and trap cropping are promising areas of current research in cultural practices. The development of molecular techniques for identification of plant-parasitic nematodes to species, online databases to rapidly search out nematode resistant crops, computerized soil temperature monitoring equipment, computer models for calculating nematode degree-days, and a greater understanding of nematode biology and population dynamics make it possible to develop promising scenarios to reduce damaging nematode populations and increase yields.
