Abstract: | The incorporation of the photoactive red food dye, phloxine B, into integrated pest management strategies has been suggested for the control of various insect pests. Inclusion of such a chemical pest control agent may interfere with a microbial pest control agent. Thus, representative fungi with potential for biocontrol were tested for their responses to phloxine B (0.01%) at different temperatures. Growth rates at selected temperatures were inhibited by dye in the presence of light for Coniothyrium minitans and Verticillium lecanii. Trichoderma virens growth was inhibited in light and dark. At optimal growth temperatures, Beauveria bassiana growth was inhibited only by the photoactivated dye species, while growth of Stilbella erythrocephala was not affected by the dye even in the presence of light. |
