Hello all. Since there are approximately 100,000 species of plant rusts
around the world, i f one's garden is infected, I think it might be
premature to destroy one's collection. It's like killing the baby to cure
All diseases (in general) are dependent on an interaction of factors,
presence of the disease organism, resistance of the host, conditions in the
external environment favoring appearance of the disease.
Rusts, for the most part are hindered by dry weather, enhanced by moist
conditions and lack of circulating air.
The Gusman's note in their book, unfortunately is insufficient to learn
about control. I had a lot of what appeared to be rust come in on gladiolus
bulbs this spring, and it appeared to be internal to the corms rather than
on the outside. I have seen it on plants in my yard and I regard it as a
sign that the plant is lacking in some kind of nutrient, or necessity. My
advice is, treat it with a broad well-rounded liquid fertilizer with a full
range of micronutirients. Don't use manure or composted material from an
unknown source, wait until next year to see what transpires. Consider an
aspirin drench for each plant of approximately 2 tabs per gallon of water.
I use this on all plants which are in any way endangered ansd have saved
many. Refefences are available on the internet using keywords such as
aspirin, acetylsalicylic acid, SAR (syemic acquired resistance.). Good lu
ck and let us know how you do. Regards, Adam in Glenview, IL USDA Zone 5a
