- Alternaria alternata in sunflower (Leaf spot)
- Botrytus faba in bean (Leaf spot)
- comprising the steps of:
- chelating copper salt with;
- acrylic polymer and natural resin by dissolving the copper salt in water with agitation, by dissolving acrylic polymer in water with agitation, and by dissolving natural resin in water with agitation to form a solution of a fungicidal composition;
- and
- applying the fungicidal composition solution to plant tissue with the water carrier to enable the fungicidal composition to penetrate the plant tissue to control fungi that may be residing in the plant.
