摘要

The Organic Materials Review Institute (OMRI) is a non-profit organisation providing an independent review of products intended for use in organic production systems to certify compliance with US national organic standards. Since all adjuvants to be used in organic agriculture production are required to meet these standards, OMRI's certified list of products is a convenient starting point when developing organic pest control formulations. In the current study, six OMRI-certified surfactants are tested for their compatibility with three common entomopathogens: Beauveria bassiana, Metarhizium brunneum and Isaria fumosorosea. The fungi were evaluated in two common propagule forms, solid-state produced conidia and liquid-media produced blastospores. The results show that most of the surfactants are compatible with the fungi at a high surfactant concentration (2% w/v). In general, the conidia showed a higher susceptibility (greater reduction in spore germination) to the surfactants than the blastospores under these conditions. In addition, the surface tension and foaming properties of the surfactants were determined.
