Nematode Control Questions

Question 1

Submit Answer 1

Answer 1

Nematodes are uncommon; pest nematodes are usually rare. However, low densities of pest nematodes can cause considerable damage to crop plants, and population size can change rapidly. Fungi that control pest nematodes will also control beneficial nematodes, thus a specific interaction is preferable. It is extremely difficult to have biocontrol agents present in sufficiently high concentrations to prevent early stages of damage, but classical approaches may enable pest nematode populations to be suppressed.


Question 2

Submit Answer 2

Answer 2

Probably. The organic matter will support a high density and diversity of all microbes, including nematode-trapping and parasitic fungi. Nematodes can be parasitised by a range of microbes and eaten by other arthropods. These organisms will be present in organic matter. However, organic matter breaks down rapidly, and in agricultural and horticultural systems, requires regular replenishment.
