Content: Most such materials will injure or kill plants if applied too close to their root zones. As the number of commercially available nematicides decreases, greater emphasis has been placed on the development of alternative IPM practices. 4. Biological Control
• Although not widely available, scientists have explored the use of antagonistic fungi like Arthrobotrys dactyloides to trap and parasitize plant pathogenic nematodes. Pasteuria penetrans, a bacterial parasite, can also be used as biological control. Figure 4. White female soybean cyst nematodes on root surface. Photo courtesy R. D.

• Avoid importing soil (or plants with soil on their roots) from areas that could be loaded with a dangerous nematode species new to the area.
