ECOTOXICOLOGY

Effect on birds: Acute oral LD50 for Mallard is >1590 mg/kg. Effect on fish: Acute LC50 (96 h) for Rainbow trout is 1.134 mg/l. Effects on aquatic invertebrates: Acute EC50 (48 h) for Daphnia magna is 6.75 mg/l. Effects on algae: Acute 72 hour EC50 for Pseudokirchneriella subcapitata is 4.9 mg/l. Effects on bees: contact acute 48 hour LD50 is >30 μg/bee, oral acute 48 hour LD50 is >112 μg/bee. Effects on earthworms: Acute 14 day LC50 is >331.5 mg/kg.

ENVIRONMENTAL FATE

Animals After oral administration, penconazole is rapidly eliminated practically to entirety with urine and faeces. Residues in tissues were not significant and there was no evidence for accumulation. Plants Metabolic pathways are hydroxylation of the propyl side-chain, conjugation to glucosides or metabolism to triazolylalanine and triazolylacetic acid. Soil/Environment DT50 in soil is 133-343 d, depending on soil type. DT50 for photolysis is 4 d (natural sunlight).  

Usage: Penconazole was introduced by Ciba-Geigy AG (now Syngenta AG). It is a fungicide used to control fungal pathogens, particularly Ascomycetes, Basidiomycetes and Deuteromycetes.

Application: Biochemistry Sterol demethylation inhibitor; inhibits cell membrane ergosterol biosynthesis, stopping development of the fungi. Mode of action Systemic fungicide with protective and curative action. Absorbed by the leaves, with translocation acropetally. Uses Control of powdery mildew, pome fruit scab and other pathogenic Ascomycetes, Basidiomycetes and Deuteromycetes on vines, pome fruit, stone fruit, ornamentals, hops and vegetables, at 25-75 g/ha.
