Synchronous Production of Conidial Powder of Several Fungal Biocontrol Agents in an Upright Multi-tray Conidiation Chamber

CHEN Chun, FENG Ming-guang (Institute of Microbiology, College of Life Sciences, Zhejiang University, Hangzhou 310058, China)  
A self-developed upright multi-tray conidiation chamber was used to synchronously produce high-quality conidial powder of fungal biocontrol candidates including two strains of Metarhizium anisopliae, one strain of M. anisopliae var. anisopliae and two strains of Beauveria bassiana. Six kilograms of steamed rice (dry weight) was inoculated with liquid cultures of each fungal strain and then equally allocated to three trays of the chamber for six-day growth and conidiation at 25℃. Among the five strains tested, the strain B. bassiana 2860 had a maximal yield of 2.2×1012 conidia per kg rice and could be potential for development into commercial formulations against insect pests.
