How effective is potassium permanganate against cucumber diseases? - John@ - 09-04-2017
I've been trying to find some facts about this to no avail. All I found was that potassium permanganate is a fungicide and bactericide that can be used against oidium, fusarium ( cucurbit family), peronospora, verticulium (solanaceae family), phomopsis cane and leaf spot of grape vine. Pls does anyone have additional info about this? Tnks.

It may work for some diseases, but until you're very sure, it is safer to use well-known systemic and contact fungicides. Or better still, rotate it with well known fungicides.

You can buy it anywhere they sell school laboratory chemicals.

Thanks @Henlus. I was scouting out for possible organic means of controlling crop pests and diseases.

I have tried potassium permanganate on young pepper plants at 1g per liter with no bad effect.
