Nematodes are considered beneficial because they will help compost and provide nutrients for the soil the plants are growing in. Insects and arachnids help the growing process because they prey on non beneficial organisms that consume plants for food. Fungi help the growing process by using long threads of mycelium that can reach very long ...
The idea that plants can benefit from the application of their herbivore's enemies is the principle behind biological control. Consequently, much of EPN biological research is driven by agricultural applications. Examples of the top-down effects of entomopathogenic nematodes are not restricted to agricultural systems.
Soil mesofauna feed on a wide range of materials including other soil animals, microorganisms, animal material, live or decaying plant material, fungi, algae, lichen, spores, and pollen. [4] Species that feed on decaying plant material open drainage and aeration channels in the soil by removing roots.
Depending on its species, a nematode may be beneficial or detrimental to plant health. From agricultural and horticulture perspectives, the two categories of nematodes are the predatory ones, which kill garden pests; and the pest nematodes, which attack plants, or act as vectors spreading plant viruses between crop plants.

Heterorhabditis bacteriophora is a species of entomopathogenic nematode known commonly as beneficial nematodes. They are microscopic and are used in gardening as a form of biological pest control . They are used to control ants , fleas , moths , beetles , flies , weevils , and other pests.
Feeding types of plant-parasitic nematodes This article is an attempt to list all agricultural pest nematodes . Species are sorted in alphabetical order of Latin name.
They have been used in companion planting as pest control in agricultural and garden situations, and in households. Certain plants have shown effectiveness as topical repellents for haematophagous insects, such as the use of lemon eucalyptus in PMD, but incomplete research and misunderstood applications can produce variable results.

plant disease control agents: include Trichoderma spp. and Ampelomyces quisqualis (a hyperparasite of grape powdery mildew); Bacillus subtilis is also used to control plant pathogens. [6] beneficial nematodes attacking insects (e.g. Steinernema feltiae) or slugs (e.g. Phasmarhabditis hermaphrodita) entomopathogenic viruses (e.g..
