How is Trichoderma used as a biocontrol agent?

How is Trichoderma used as a biocontrol agent?

Biocontrol mechanisms of Trichoderma: The Trichoderma may suppress the growth of the pathogen population in the rhizosphere through competition and thus reduce disease development. It produces antibiotics and toxins such as trichothecin and a sesquiterpine, Trichodermin, which have a direct effect on other organisms.

What is biocontrol mechanism of Trichoderma spp?

Trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promoting plant growth and plant defensive mechanisms and antibiosis, or directly, by mechanisms such as mycoparasitism.

What is Trichoderma PPT?

Trichoderma  Free living fungus common in soil and root ecosystem  Highly interactive in root, soil and foliar environment  Suppresses the pathogen by different mechanism of biocontrol Trichoderma harzianum.

Is Trichoderma a microbial biocontrol agent?

Short conclusion. Trichoderma being an efficient biocontrol agent, their characteristics and mechanisms should be well understood to apply them in field conditions to restrict the proliferation of phytopathogens.

Which disease is controlled by Trichoderma viride?

Trichoderma viride is a fungus and a biofungicide. It is used for seed- and soil treatment for suppression of various diseases caused by fungal pathogens….

Is Trichoderma a fungicide?

TRICHODERMA VIRIDE (BIO FUNGICIDE)

What is the use of Trichoderma viride?

Trichoderma viride is a fungus and a biofungicide. It is used for seed- and soil treatment for suppression of various diseases caused by fungal pathogens.

How do you isolate Trichoderma?

Method for isolation of Trichoderma Soil samples are collected, air dried, and ground into powder. Stock solution of sample is prepared by dissolving 10 g of powdered soil sample into 90 mL of distilled water. Next, serial dilution of samples were prepared as 10−1, 10−2… 10−5.

Is Trichoderma a fertilizer?

Trichoderma used in almost all type of crops, with or without any amendments, but if Trichoderma biofertilizer is used as an amendment with compost may gives better results than any other fertilizer. The biofertilizer also used as soil conditioner, improves the population of plant beneficial microorganisms in soil.

What is the biocontrol ability of Trichoderma?

Biocontrol of Bacteria and Phytopathogenic Fungi – Trichoderma stimulates growth and flowering of several plant species. Thus, the biocontrol ability of Trichoderma strains is most likely conferred by more than one Trichoderma stimulates growth and flowering of several plant species.

How many species of Trichoderma are there?

Trichoderma 6 fungal species that include Trichoderma (6 strains), Gliocladium virens (2 strains), Trichoderma harzianum (2 strains), Trichoderma viride Biocontrol of Bacteria and Phytopathogenic Fungi – Trichoderma stimulates growth and flowering of several plant species.

What is the best media for the growth of Trichoderma?

PDA medium was the best for biomass and spore production of Trichoderma species (Mustafa et al., 2009). (PDA/ Waksman Agar/Agar Agar/ Corn Meal Agar/ Czepak’s Agar). Mycelial growth was good at the temperature range of 30-37ºC while sporulation was favored by 30-45ºC.

How does Trichoderma interact with the root cortex?

Trichoderma–plant interaction Plant root colonization The hyphae penetrate the root cortex but the colonization by Trichoderma is stopped, probably by the deposition of callose barriers by the surrounding plant tissues.
