Biocontrol fungus

One of the earliest successes in biocontrol was the use of Aschersonia aleyrodes to control citrus white flies in Florida Berger, Another species of rust has also been tested for the control of thistles Fig.

Disadvantages High concentrations of spores are often needed to get adequate control of pests in a crop, which can cut down on the cost effectiveness of fungal products.

Biological pest control

Naturally occurring albino strains of Ophiostoma are being tested to control dark staining fungi. Insect cavity filled with fungal spores.

However, the specific reasons for these declines were never reached. Paecilomyces fumosoroseus is effective against white flies, thrips and aphids; Purpureocillium lilacinus is used against root-knot nematodesand 89 Trichoderma species against certain plant pathogens.

Several large cities in the Midwest have recently detected alarming levels of herbicides and other pesticides in their water systems. Not removing dead annuals and non-hardy plants in the autumn allows insects to make use of their hollow stems during winter. Mymaridae has been introduced to control the glassy-winged sharpshooter Homalodisca vitripennis Hemiptera: However, there are problems associated with using this fungus.

Scouting A regular monitoring program is needed for early detection and to insure the success of a biological control program.

Integrated Pest Management Program

Although not commercially available, predatory hunter flies Coenosia attenuataand the parasitoid Synacra pauperi may also help to manage fungus gnats. Bti does not reproduce or persist indoors, so infestations in potting media might require repeated applications at about five-day intervals to provide control.

Most strains are highly adapted to an asexual life cycle. One reason for this is host specificity. The spores of commercially developed fungi in the group hyphomycetes are spread passively by the action of the wind, rain, or contact with other hosts or animals in the environment.

Phytophthora palmivora has been used to control milkweed or strangler vine, a major problem on citrus in south Florida Fig.

This success was repeated in California using the beetle and a parasitoidal fly, Cryptochaetum iceryae. They tend to be much more host specific; one well known species only infects aphids. These include Steinernema nematodes, Hypoaspis predatory mites, and the biological insecticide Bacillus thuringiensis subspecies israelensis Bti.

Mycoherbicides have advantages over chemical herbicides in that they can be more host-specific, preparation costs will be less expensive, and human health hazards can be eliminated. Consult with your supplier for compatibility information with other pesticides or with the following resources on the Internet:Hirsutellia Biocontrol Fungus Home» Beneficial Microorganisms» Hirsutellia Biocontrol Fungus Hirsutella is a genus of asexually reproducing fungi in the Ophiocordycipitaceae family, which contain about 65 species (Hodge ).

Commercially-available and naturally-occurring biological control agents can also control this pest.

Biological pest control

Insecticides are considered an important control option in some commercial plant production but generally aren’t recommended for fungus gnat management in and around the home. Fusarium oxysporum strain CS reduces incidence of Fusarium wilt in tomato and other crops.

To be integrated into most production systems, strain CS must be compatible with other management practices. We assessed the compatibility of strain CS with.

A biocontrol tactic used is to treat soil with the fungus Gliocladium virens before planting the cotton seed. The production of the antifungal compound, gliovirin, plays an important role in the control of damping-off. Golfers needn’t be distracted by the prospects of this biocontrol fungus quietly working underfoot, though.

How to Manage Pests

Its absolute preference for infecting white grubs and other insect turf eaters means people, pets and wildlife won’t suffer the same fuzzy fate as these pests. Fungi for the biological control of insect pests.

Organic Agriculture July 19, eOrganic author: Fungi make good biological control agents for a variety of reasons. They generally do not affect people or other mammals, making them extremely safe to use. drift from nearby fields could impact the success of a fungal biological.
