Hey Helpful Gardener forum-goers! Long-time lurker, gardening wannabe, and first-time poster here.
Kinda wish it was somewhere other than the plant disease forum, but hey! So, up 'til noqw my vege garderns have been fine. My own inexperience aside, stuff has grown pretty well, and I've been super happy with the resuts. Until now. Recently I've started to notice black marks appearing on the potatoes that I've pulled so far.
At first I thought it might just be dirt / dried mud stuck to them (have had a lot of rain recently), but after poking around a bit and doing some searching I'm now worried it might be Rhizoctonia (spelling?). Looks very similar to this:
The black marks are pretty stubborn, and definitely aren't dirt (i wish they were!). It's a little too early to tell if anything else is wrong with them. None of the other telltale signs have popped up just yet. But I'd rather be safe than sorry!
Keen to hear if anyone else has dealt with this before. And, more importantly, whether anyone has any natural methods for dealing with / treating this? I've kinda resigned myself to this batch not pulling through, but I'd like to do something to save the next lot before I plant them if possible!
Thanks in advance
