Description	Kinetic fluorescence imaging was used to set a new detection limit for plant exposure to low levels of destruxins - phytotoxins of Alternaria brassicae . A general experimental algorithm is presented that can be used to identify the combination of fluorescence parameters providing the highest contrast between the affected and unaffected plants or plant segments. Leaves of canola (Brassica napus) and white mustard (Sinapis alba) were exposed to various concentrations of destruxins and images of key fluorescence signals (F-0, F-M, F-P, and of F-S) were captured in a single kinetic experiment. Contrast was quantified within these images between the leaf areas exposed to destruxins and the untreated areas. The highest contrast was found in the image constructed by pixel-to-pixel division of images F-0 by F-P and F-0 by F-M. Using the F-0/F-M ratio image, we were able to detect exposure to destruxin concentration as low as approximately 0.05 mg l(-1) applied to canola leaf and approximately 10 mg l(-1) whe Kinetic fluorescence imaging was used to set a new detection limit for plant exposure to low levels of destruxins - phytotoxins of Alternaria brassicae .
