does anyone know what i can do to treat or stop this? i heard i can prune, and i got some fungicide, Organocide 3-in-1 garden spray ? but are plants sprayed safe to eat? i saw some instances where it dis get ride of the disease but it harmed the plant. i also think it might be too late to spray, they said to spray early in the season.
also, will it effect my other plants like roses? should i protect them too?

Welcome! I think your best bet is to contact your local Extension office and see what they recommend. The Organocide label lists fruits and vegetables and the manufacturer should be able to tell you (toll free) how long after treatment you can eat good fruits from the tree but, having said that, the label does not list rust as one of the diseases it will control.

Depending which pear rust it is it may affect another plant but I do not think it will infect roses. There is more than one type of pear rust and each affects different plants as well as pear. Your Extension office (if you're in the USA) should be able to identify the problem you have and tell you what treatment is recommended/available in your area.
