Trichoderma sp. and resistance to plant pathogen

  • Trichoderma sp.
  • Trichoderma sp.is Deuteromycetes fungi (Rifai, 1996).
  • Trichoderma can grow and form spores on media rich in cellulose such as tofu residue, cob, rice bran, rice, beer residue. Most Trichoderma grow at temperature 25 - 350C, pH 5–6.

  • Mechanism of resistance against plant pathogens of Trichoderma sp.
  • Parasitic mechanism: Trichoderma mycelium surrounds and tightens diseased mycelium, then penetrates the diseased mycelium, perforating the outer membrane and causing the decomposition of the protoplasm inside the diseased mycelium.
  • Antibiotic mechanism: Trichoderma biosynthesis of some antibiotics: Gliotoxin, Viridin, Trichodermin and Dermadin. These antibiotics are toxins that kill microorganisms that damage plants.
  • Enzymes lysis Mechanism: Trichoderma biosynthesis of some lysis enzymes: laminarinaza, chitinaza, β-glucanase, enzyme β-1,4-N-acetylglucosaminidase and enzyme endochitinase. These enzymes help Trichoderma break down cell walls, inhibit the growth of pathogenic fungi.
  • Competition mechanism: Trichoderma compete with plant pathogens for nutrients, location. Trichoderma takes up location as well as nutrients of pathogenic fungi.
  • Product Trichoderma sp. antagonizing plant harmful microorganisms
  • National Center for Technological Progress – Ho Chi Minh has been very successful in the use of strains Trichoderma sp. for many years. The branch that has produced Trichoderma product. The product is accepted and appreciated by many domestic markets. The product has very high application efficiency in agriculture.

  • The product include strains T.hazianium, T. Viride, T. asperellum and many other trains Trichoderma sp., has the ability to strongly decompose insoluble compounds into soluble substances, helping plants to absorb easily and have the ability to prevent and treat many plant diseases caused by microorganisms.
  • In addition, in this product, there are many other types of phosphorus-degrading and nitrogen-fixing microorganisms such as: Bacillus sp., Pseudomonas sp., Streptomyces sp….
