The sun and other stars generate electromagnetic radiation at all wavelengths. The relative strength of the wavelengths depends on the star's blackbody temperature.
However, Earth has an atmosphere which prevents many wavelengths of EM radiation reaching the ground, including UV light below 290 nm.

"Sunlight is below 400nm on the UV spectrum but all that is needed to be germicidal is 100-280nm. (Thanks Wikipedia!) Sawdust will also aerate in dry weather which is just good composting. Some of you guys are getting too hung up on walking through bug poo as a reason not to cut wood. Cut on a sunny day over a tarp if you're really worried. Doing nothing is not a solution."
I think you now need to explain how light from the sun that can't get through the atmosphere to the ground helps your argument.
