Suppressive effects of beneficial nematodes on plant-parasitic nematodes / by Ganpati Jagdale

Effects of beneficial nematodes on plant-parasitic nematodes- Nematodeinformation

Several previous studies (Lewis and Grewal, 2005) have showed that beneficial entomopathogenic nematodes have a potential to control plant-parasitic nematodes that cause a severe economic damage to many economically important crops.

A recent study by Caccia et al (2013) also shows that the entomopathogenic nematodes such as Steinernema rarum and Heterorhabditis bacteriophora suppressed over 53% of reproduction of one of the most important plant-parasitic nematode, Nacobbus aberrans, which is a pest of many crops including potato, tomato etc.

These studies on interactions between beneficial nematodes and plant-parasitic nematodes suggest that the beneficial nematodes can serve as environmentally safe and health conscious alternatives to chemical nematicides to control plant-parasitic nematodes.
