White Rust Disease – What is White Rust?

What is white rust? It’s a disease that causes distinctive chalky white spore masses sometimes referred to as pustules that first show up on the underside of leaves. These blister-like masses, called sori, form under the leaf’s dermis (skin) and can’t be scraped off without damaging the leaf. The stem and leaves can become twisted and deformed. White rust disease can and will infect the floral parts as well. Broccoli and cauliflower, in particular, will produce grossly deformed heads and for those gardeners who collect seed for the following year’s planting, those seeds will be sterile.
 

White Rust Treatment

If your garden has been plagued by white rust disease in the past, you should look for resistant strains in the future. There are no fungicides specific to white rust treatment and once the disease becomes rampant, there is little to be done. That being said, fungicides used to treat downy mildew are sometimes effective against white rust, particularly the leafier crops. Treatment must begin at the first signs of infection. The methods for controlling white rust fungus or how to prevent white rust are largely organic.

The control of white rust fungus depends on the understanding of the life cycle of fungi in general. Fungi reproduce by producing spores; tiny, microscopic cells, each of which is capable of becoming a fungus and thus establishing a new colony– what we see on the leaf or stem. Due to their minuscule size, these spores are carried easily from plant to plant, or garden to garden, by wind or water. Since there is a protective coating, many of these spores can lay dormant for long periods of time, surviving in both cold and arid conditions. When conditions are right again, they ‘blossom.’
