How does Southwell AC work?
Southwell AC Fungicide is Chlorine Dioxide in an 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 defences down. What makes fighting these pathogens even more difficult is their ability to develop a resistance to most chemicals.
Except for Southwell AC Fungicide. Southwell AC controls both fungal and bacterial diseases and is not subject to bacterial or fungal resistance.

Used it on a buxus headge with blight. Sprayed soil surrounding as well. Really effective with new growth in earler dead patches. Good order process and delivered promptly..(The headge needs a cut I know)
Don't need a handler's certificate for this. Helped dry up the botrytis in our flowers.
I had some early blight showing on leaves and fruit from December. I have pruned all leaf and fruit with disease and then sprayed DX50 fungicide 4 times in the evenings of that first week. One week later (after being away), i have come home to disease free fruit and vines!
I will keep up with the evening spray a couple times a week still.
Works well on red thread on the lawn
The only effective fungicide.
Haven't used yet. Sick of getting these review emails so putting this on to stop them
Very happy with service
Have sprayed my lawn twice in 2 weeks. It's looking better already. Seems to kill the redthread that was badly effecting my lawn
Product delivered promptly. Instructions on container are clear and concise.
Have sprayed the soil and am awaiting results.
Prompt delivery. Easy to deal with. Sprayed my lawn for brown patch virus. Two weeks now and still spreading. Applied a second spray, waiting to see.
