Which of the following fungi is Predaceous on nematodes?
The Endoparasitic fungi are species of Cephalosporum, Meria, Verticillium, Catenaria, Meristacrum etc. Catenaria anguillulae produces zoospores which track down Nematodes by swarming, eventually encyst near Nematode body orifice, penetrate and colonize the prey.

How do you control nematode?
The most reliable practices are preventive, including sanitation and choice of plant varieties. You can reduce existing infestations through fallowing, crop rotation, and soil solarization. However, these methods reduce nematodes primarily in the top foot or so of the soil, so they are effective only for about a year.
Which bacteria is used as biocontrol agent?
Bacteria, fungi and viruses can all act as biocontrol agents due to the large diversity of target species and the variety of methods of action. Important examples of microbial biocontrol agents include Bacillus thuringiensis, fluorescent pseudomonads and Beauveria bassiana.
What is plant parasitic nematode?
Plant parasitic nematodes are microscopic worms which are generally filiform (at least at one of their stages), ranging from 0.5 mm (e.g. Meloidogyne, Pratylenchus) to 4–5 mm (e.g. Xiphinema). A wide variety of nematodes affect plants and some of them have a significant economic impact on commercial crops.
