SUMMARY: Conidia of germinate in the presence of sublethal concentrations of benomyl to produce swollen and distorted germ tubes which branch more frequently than those of normal conidia. Multiple germ-tube emergence also occurs to a greater extent in treated conidia.

The orientation of organelles towards the hyphal tip is disorganized in benomyl-treated germ tubes. Endoplasmic reticulum which occurs as multiple strands surrounding the nuclei in normal germinating spores is broken up into a fragmented network. Part of the endoplasmic reticulum occurs as strands and vesicles close to the plasmalemma, a configuration which corresponds closely to the situation in resting conidia. The findings inchemically fixed sections are confirmed by the appearance of freeze-etched replicas. Benomyl treatment seems to stimulate lomasome formation, and freeze-etched treated nuclei appear deeply lobed and convoluted.
