| Abstract | ||
| This study aims to use safe agents and microorganisms to control citrus nematode, Tylenchulus semipenetrans infected Naval orange to protect humans and plants from bad side effects of different chemical pesticides. The tested agents are Indole butyric acid (IBA); Entomopathogenic nematode (Steinernema feltiae) and Predacious nematode (Diplogaster lheritieri) singly or in combination under greenhouse conditions. The results showed that, the superiority of the nematode predator, D. lheritieri giving reduction percentages (73.9%) on citrus nematode compared to entomopathogenic nematode, S. feltiae (50.8%). The combined treatment (IBA+ D. lheritieri) recorded the highest reduction percentages on citrus nematode (77.4%) compared with the nematicide Tervigo (77.2%). In addition, achieved combined treatment gave a better enhancement of Naval orange growth parameters such as plant height which increased by (84.7%), shoot weight increased by (64.2%), and root weight increased by (131.9%) , meanwhile, the percentage of citrus nematode females per 1 g roots was decreased by (90.3%) compared to control treatment. This study recommends that, the use of certain safety methods for combating citrus nematodes can substitute of chemical control. Also, it recommends that, entomopathogenic nematodes not to be used with predatory nematodes in the same control program against citrus nematodes because there were negatively effect between each other. | ||
