A fungal biocontrol preparation for control or prevention of plant fungal diseases comprises sporulated fungal biomass, a carrier and acid. The carrier preferably is vermiculite. The biocontrol preparation is resistant to bacterial proliferation in storage and handling and is effective in controlling damping-off diseases caused by soilborne fungal pathogens.

Fungal formulation for biocontrol of soilborne plant pathogens

This invention relates to a method for preparing pellets containing living biocontrol fungi and nutrient dispersed throughout. Living fungi are selected and grown for inoculum. The fungal propagules and wheat bran are added to a sodium alginate solution. The fungal propagule-alginate-bran mixture is added dropwise into a solution of calcium chloride. The resultant alginate gel pellets containing living fungi can be dried and used to inoculate agricultural fields infested with soilborne diseases.

Preparation of pellets containing fungi and nutrient for control of

A new strain of the fungus Trichoderma viride designated as T-1-R9 is described. The new strain is an effective biocontrol agent for fusarium wilt of chrysanthemum.
