many fungi have antagonistic activity such as Chaetomium globosum ,Penicillium dangeardii ,Verticillium lecanii , Pythium oligandrum ,Gliocladium and some yeast like Aureobasidium pullulans.
Yes, there are a lot of antagonistic fungi such as Talaromyces flavus , Gliocladium sp.
Actually, it depends on your target, for example, if you want to control Tylenchulus semipenetrans (nematode), you can use an antagonistic fungus such as Paecilomyces, Cladosporium, Acremonium even Fusarium! So you have a lot of choices.
The most common antagonistic fungus that I encounter in my work is the coelomcyete Sphaerellopsis filum (syn. Darluca filum), which is a hyperparasite of rust pathogens and has been found on rust sori produced by the fungi causing Chrysanthemum White Rust (Puccinia horiana) and lemongrass rust (Puccinia cymbopogonis) from Mexico.
Of course, there are many fungi can be used as antagonestic fungi against other pathogenic fungi, insects, nematodes and other pathogenic microorganisms. These fungi are:some species of the genera Paecilomyces , Verticillium, Metarhizium , Gliocladium, Cladosporium, Penicillium, Chaetomium, non pathogenic isolates of Fusarium, non pathogenic isolates of Rhizoctonia..... etc.
Paecilimyces against root knot nematode, Phanerochate in root rot fungi... also helping in expedite the decompotion process helpful in increasing nutients in soil
Yes There is ...Depend on what you want from your Biocontrol Agent
For example Trichoderma is used both at Classical and "mainly" Augmentative control.
the large use (application) of Trichoderma make it god good as symbio (Boost Plant growth) and parasitic against soilborne ... areal germs (fungi most of the time)/insect ..
Trichogramma which has same Prefix as Trichoderma is a Biocontrol parasitoid Wasp oriented towards Insect parasitism though !
For Fungi there is many different way to use them
Rhizoctonia / Verticillium / against other pathogenic fungi
Metarhizium popular against Locust/crickets
I just now learn in that page question new things too ...Thank you for Valuable Informations and for sharing knowledge
