Five fungal biocontrol agents useful in agriculture were grown on rice flour in plastic bags. The flour, infested with Colletotrichum truncatum, an Alternaria sp., Paecilomyces fumosoroseus, or atoxigenic Aspergillus flavus and A. parasiticus, was mixed with wheat flour, kaolin, and water and extruded into granules. The inoculum survived extrusion and fluid bed drying at 50°C 3–92 times better than inoculum produced in liquid fermentation. Depending on the agent, the high level of flour infestation permitted a 1:9 to 1:1600 dilution to yield the 1×106 cfu/g in the final product which is usually needed for biocontrol efficacy. © Rapid Science Ltd. 1998 [ABSTRACT FROM AUTHOR] |
