Product Description

Viathon® is a broad-spectrum fungicide that utilizes three modes of action for cost-effective disease control in various crops. It contains two active components — tebuconazole and potassium phosphite. Tebuconazole works systemically for consistent disease control. Potassium phosphite controls diseases with two modes — first by inhibiting fungal growth and second by activating the plant’s immune system in a process called SAR (Systemic Acquired Resistance).

In order to achieve maximum results in controlling/suppressing the diseases, carry out spraying before the appearance of the diseases or when diseases are first observed.
