How to prevent
It is best to take the necessary preventive measures to avoid septoriosis. They include but are not limited to collection and disposal of fallen leaves and fruits, pruning of dead shoots with parts of healthy tissue, and fungicide solutions treatment (such as copper and iron sulfate) in much lower concentrations than the therapeutic ones. Plants with strong immunity can fight any disease if they have a suitable growing environment and appropriate care. As is often the case, this disease affects the weakest plants, those that lack proper care.
The smartest method of fighting septoria pathogens in plants is by using fungicides. Still, many planters oppose plant treatments involving chemical substances and rely on less toxic natural remedies that prevent the negative consequences of such treatment, like the chemical burns of leaves. However, if the damage is substantial, there might not be any other effective approach than industrial fungicides.
