A zeolite-water heterogeneous mixture (1:2 w/v) was found suitable medium for growing Turkish isolate of Trichoderma harzianum T1. Pelletized formulations of zeolite containing conidia of Turkish isolate of Trichoderma harzianum T1 in alginate were prepared. Formulations were more viable at 4°C than at 30°C.

Key words: Trichoderma harzianum T1, formulation, sodium alginate, zeolite, survival.
