AbstractAn ultraviolet spsctrophotometric and a microbiological assay were used to determine residues of benomyl and its derivative carbendazim on banana skin and pulp. Two alternative procedures for the purification of pulp extracts are described and recovery values from laboratory‐treated bananas are compared.

Reproduction, teratogenic, and mutagenic studies with benomyl
Toxicology and Applied Pharmacology, 1975Abstract In a three-generation rat reproduction study with benomyl fungicide, no reproduction or lactation differences were observed among control and test groups of animals at the highest dietary level of 0.25% benomyl. No pathologic changes were found in tissues from weanling pups of the F 3B litter. In a teratogenic study, feeding of as much as 0.

Methyl, ethyl, and hexyl isocyanate homologues of benomyl (MBC-MIC, MBC-EIC, and MBC-HIC, respectively) were prepared and compared with benomyl (MBC-BIC). In water (pH 6.2), the half-lives of these compounds were 2.7-7.7 times greater at 178 μM than at 1.78 μM. They were less stable at 10 and 25 o C than at 1 o C.

The Metabolism of Benomyl Fungicide in Mammals
Xenobiotica, 1973Abstract1. The metabolism of Benomyl (methyl 1-(butylcarbamoyl)-benzimidazol-2-ylcarbamate) has been studied in mice, rabbits and sheep, and in enzyme preparations from these species.2. In all three species two metabolites were formed by hydroxylation, and two by ester hydrolysis.

Benomyl-induced aneuploidy in mouse oocytes
Mutagenesis, 1992Benomyl (methyl-1-[butylcarbamoyl]-2-benzimidazole carbamate) is a plant fungicide which acts by inhibiting tubulin polymerization. It is also a carcinogen and a teratogen. A substantial number of reports consistently show that benomyl inhibits cellular division and induces numerical chromosome changes in somatic cells, while results from standard ...

Monitoring of Exposure to Benomyl in Nursery Workers
Journal of Occupational & Environmental Medicine, 1996We compared urinary levels of the metabolite methyl-5-hydroxy-2-benzimidazole carbamate (5-HBC) among nursery workers exposed to the fungicide benomyl (specifically Benlate 50 DF [DuPont, Wilmington, DE]) and workers not exposed to benomyl. Environmental exposures were quantitated from gloves, body patches, and air samples collected with area and ...

Effectiveness of Benomyl and Benomyl-Folicote Treatments in Reducing Ozone Injury To Pinto Beans
Journal of the Air Pollution Control Association, 1972The body of information presented in this paper is directed to individuals interested in effects of air pollution on vegetation. The effectiveness of the systemic fungicide benomyl (methyl i-(butylcarbamoyl)-2-benzimidazolecarbamate) and the ahtitranspirant Folicote (hydrocarbon paraffin wax emulsion) in reducing ozone injury to plants of Phaseolus ...

Effect of benomyl on reproduction in the male rat
Toxicology Letters, 1982Adult Sprague-Dawley male rats (65 days of age) received 10 daily treatments of 0, 200 or 400 mg benomyl/kg/day by gavage. Body weight, tissue weights, total epididymal sperm counts and sperm concentration from the vas deferens were measured 14 days after the last treatment.

SUMMARYA bioassay using Botrytis cinerea detected 0–05 ppm benomyl in potato dextrose agar. Nine species of Cochliobolus, fourteen of Drechslera, four of Helminthosporium and five of Pyrenophora tolerated the presence of benomyl to the same extent, and grew on agar plates containing 40 ppm of the compound.

Bacterial breakdown of benomyl. II. Mixed cultures
Antonie van Leeuwenhoek, 1978Experiments with mixed bacterial cultures grown in liquid media which contained the benzimidazole fungicide benomyl, with or without Na-lactate, as source of carbon provided circumstantial evidence for cleavage of the benzimidazole heterocyclic ring.
