Hi Happy Easter to all. Am finding a white powder like substance on the underside of my Broccoli and cauliflower leaves. (see picture). Gisborne Victoria has been very humid lately which is unusual for our area this time of year. Is this a fungus and if so how can i treat it ?

Hi guys thanks for the information. Have done some research over the past few weeks and found that some people use downy mildew treatments on White blister or white rust. Treated early for best results. So, I tried using Baking Soda mixed 1 tablespoon to 1 litre of water. They say rain or mineral water is best. Spray only when the leaves are dry and no sign of rain for a while, apply to both sides of the leaves.

Fantastic result and as you can see proof is in the eating.
