Help stem is rotting!!

I noticed this patch at the base of the stem that is rotting. Now the branch has broken. The plant has about 1 month of flowering left. Will it survive?

Oops big pic...

looks like fusarium, i would say stem rot but that is almost always at the base of the stem. If it is only a month it will probably survive. but fusarium will spread to all your plants. I would put some hydrogen peroxide on it, use a q-tip just dab it on dont let the stem get to wet. Or maybe a fungicide but i wouldnt this close to flowering.
Hope that helps, also if it is fusarium it will have spores clean whole room with bleach solution

well looked at pic again and you are outside wheeeww

Fusarium?! eek :O

Thanks for the input. Think I will just leave the tree alone and see what happens. Other plants are fine. This is my biggest plant though.
