Description

paclobutrazol: RN given refers to (R*,R*)-(+-)-isomer [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

paclobutrazol : A racemate comprising equimolar amounts of (2R,3R)- and (2S,3S)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-ol. It acts as a plant-growth retardant and fungicide via inhibition of gibberellin biosynthesis.

Research Excerpts

Toxicity

Paclobutrazol is used as a fungicide and as a plant growth regulator. There are few studies about its potential toxic effects. The neurotoxicity of paclobUTrazol can be interpreted as the mediating effect of oxidative stress in zebrafish.
