I have a sizable collection of aloes and I suspect a few of my aloes may be infected with 'aloe cancer'; although, no signs of abnormal lesions/galls are apparent. (I had acquired a number of aloes at a nursery which later I found had infested aloes in their collection).
As a preventative/proactive measure, is there a chemical treatment I could use to boost the immunity of my aloe collection against the 'aloe cancer'? Or should I just keep a close eye for any abnormal lesions and then treat accordingly? Thanks
