|The white fuzzy stuff sounds like a fungus, not the results of spider (or spidermite feeding). It's difficult to diagnose without seeing the plant but gray mold (botrytis) oftens attacks plant stems and causes the symptoms you describe. Once you see the damage, you can't really control the problem - the disease is throughout the tissues and fluids of the plant. Insects can sense when plants are stressed and generally will gravitate towards sickly plants so their presence is of secondary concern. You don't want to hear this - but the best thing to do is dispose of your begonias and start all over with healthy new plants. I don't think yours can be saved.
