Author Topic: Seeking suggestions on how to deal with a fungal infection on young Trichocereus  (Read 36 times)

Hey everyone, some of my Trichocereus have what I assume is a fungal infection thats spreading. I've isolate them from healthy plants and treated with copper fungicide but it hasn't had much effect. Just hoping maybe someone who's dealt with something similar could offer any advice.

Daconil works well for me. It isn’t systemic, so it works on the surface and won’t absorb into the plant.

Of course, always use a well draining soil mix and don’t overwater.

That doesn’t look too bad though. It is mostly already healed. The tan color is scarring that will never go away. Black or red indicates actively growing fungus.
Undergoing the formality of being alive.
