Uses of Clean Cup
As a fungicide, Clean Cup can be applied to agricultural fields to control crop diseases.
Bacillus subtilis, the active ingredient in Clean Cup, has no adverse effect on crops. Therefore, Clean Cup can be pre-applied to farmland. In this way, Clean Cup can prevent microorganisms that can cause crop diseases from infecting the crops. Specifically, Clean Cup is highly effective in preventing powdery mildew and gray mold. It is also effective against leaf mold in tomatoes and mini-tomatoes, as well as downy mildew and brown spot in cucumbers.
