Abstract
This invention relates in part to the use of osmoticants to provide desiccation tolerance to growth producing cells of microorganisms upon drying and reconstitution. This invention also relates in part to the discovery of liquid fermentation media permitting production of high levels of conidia of Trichoderma harzianum in liquid fermentation, and modifications to these media that produce conidia that are resistant to desiccation and that provide enhanced biocontrol efficacy.
