    Improved fungicide

    With Southwell AC Broad-spectrum Fungicide, viticulture and horticulture have an advanced product that helps control both fungal and bacterial diseases of plants.

    ​How does Southwell AC work?

    Southwell AC Fungicide is Chlorine Dioxide in aqueous solution which kills by penetrating the cell wall of the target organism and disrupting its food supply. The triggering action for Southwell AC is the sugar-like substances that are an integral part of the target pathogen cell walls.  Due to this mode of action, disease bearing organisms cannot build up resistance to the product.   

    Under certain conditions (heavy rain, high humidity, specific temperatures), disease multiplication can be very aggressive in susceptible host plants.  Southwell AC kills rapidly on contact so early detection of disease should be followed by an application of Southwell AC Fungicide.

    Winning the War

    Fungal growths are easy to fight because they’re visually apparent.  Bacterial diseases, however, are harder to combat because they are caused by an unseen, well organised enemy.  These concealed microbes spread disease by fooling plants into keeping their defenses down.  What makes fighting these pathogens even more difficult is their ability to develop a resistance to most chemicals. 

    Except Southwell AC Fungicide.  Southwell AC controls both fungal and bacterial diseases and is not subject to  bacterial or fungal resistance.
