Conteúdo: | Gray mold caused by Botrytis cinerea is an important disease of strawberry. Clonostachys rosea is a mycoparasite of B. cinerea that reduces fruit losses when used as a biocontrol agent. Since spore production by C. rosea has not been optimized, we investigated factors affecting sporulation under aseptic conditions on white rice grains. The greatest spore production in glass flasks, 3.4 109 spores/g-dry-matter (gDM),occurred with an initial moisture content of 46% (w/w wet basis), inoculated with 1 106 spores/gDM and hand shaken every 15 days. However, a lower inoculum density (9 103 spores/gDM) and no shaking also gave acceptable sporulation. In plastic bags 1.1 108 spores/gDM were produced in 15 days, suggesting that larger scale production may be feasible: with this spore content, 24 m2 of incubator space would produce sufficient spores for the continued treatment of 1 ha of strawberry plants.
