Great product for fighting mysterious rots/virus/disease on orchids. I wouldn't use it on vegetables, but for orchids it is the ultimate last resort when you're scared for your collection.
use it very dilute. comes with very detailed instructions for every type of application imaginable. also great for sterilizing work areas and tools before orchid repotting/dividing.
