Abstract/Contents: | "Bioassays using pellets of agar, thatch-agar and turfgrass-agar were developed using benzimidazole-sensitive Penicillium expansum Link, to detect the fungicide methyl benzimidazol-2-ylcarbamate (MBC) which is the major fungitoxic degradation product of benomyl [methyl 1-(butylcarbamoyl)benzimidazol-2-ylcarbamate] in thatch and turfgrass clippings. These bioassays were used to estimate the amount of fungicide that was biologically available and hence, by subtraction from that applied, the amount that remained bound and biologically unavailable. The limit of quantitation was 0.5 mg kg⁻1. From 19.9% to 93.2% of the applied fungicide was bound depending on the concentrations used. In-vitro degradation studies showed that MBC had a half life of approximately 2.5 weeks at 23°C in non-sterilized thatch." |
