What does the published scientific research say about Typhula phacorrhiza?

Typhula phacorrhiza is a fungal biocontrol agent studied in peer-reviewed research for suppression of gray snow mold, a turf and small-grain disease caused by Typhula ishikariensis and T. incarnata. PubMed indexes one published study on this organism in a plant-input context (PMID 30856825), documenting its field performance applied to turfgrass prior to snowfall.

The study also evaluated pelletized alginate formulations of Typhula phacorrhiza containing kaolin clay. After 64 weeks of storage, viability exceeded 85% at -15°C and 70% at 4°C, though it dropped below 30% at warmer temperatures. The published data report that 20 g/m² of pelletized inoculum achieved snow mold control equivalent to 200 g/m² of mixed grain inoculum, a formulation efficiency finding cited in peer-reviewed literature.
