Jordan it won't be possible to put your flasks under the UV light, because the intensity that will kill the fungi will also most probably kill the plantlets. See how I say 'most probably' there would be no way to actually determine it without a bit of experimenting with different exposure times and intensities etc. You may find that the fungi dies, the plants survive with some defects, or the plants die and the fungii surviveor both die or both survive LOL. Even if the fungii died and your plantlets survived they will have severe mutations, UV light is a leading cause for mutations which give rise to skin cancers in humans which you already might know (living in Aus and Nz). Yes as BD pointed out there are UV lights that come in a broad range of energy spectrum from 100 to 400 nm wavelengths, but the wavelenths from 250 to 300 are the most germicidal ones. But I guess UV is not an option fro killing the contamination. One option would be to immediately deflask and plant the plantlets in compots after thoroughly cleaning them with mercuric chloride or replanting them in other sterie flasks after the mercuric chloride decontamination step.
