Encapsulation of Trichoderma harzianum Rifai in sodium alginate pellets

The introduction of antagonistic fungi in the soil as biocontrol agents (BCA) against phytopathogenic soil borne fungi is often difficult. The introduced antagonistic fungi must adjust to the environment and survive. Initially, it is compete with harmful microbes for the occupation of the rhizosphere, trying to colonize the available sites along the plant roots and prevent pathogens from making contact with the root tissue. Therefore, BCA that use competition to suppress disease generally need to be applied in high densities before the pathogen is present. The development of effective, low-cost fungal inocula engineered to maintain inoculum potential during transport, storage and application, is one of the keys to the commercialisation of the fungal soil remediation. Most of the examples on different types of fungal inocula carriers for biological control include peat, granular vermiculite or clay mixtures, grains and alginate pellets. The objectives of this work was to determine the possibility of dispersal of an isolate of Trichoderma harzianum (TKP) in the soil in the form of sodium alginate pellets, and to determine the effects of the isolate TKP on the germination of the ˛pelleted˛ flax seed (seed coated with spore suspension of the isolate TKP and sodium alginate).
