Don’t let allium rust deter you from growing this great plant family. Take measures to keep rust out of your garden and you’ll do fine.
Cease and Sonata also only come in gigantic sizes and I think you need a farmers/growers license to purchase one of them. Smaller sizes of biofungicides I’ve found are Monterey Complete Disease Control and Bonide’s Revitalize. A lot of these, including Serenade, need to be applied preventatively to work well but they are not fail safe and disease can still occur! Considering the time, effort, cost, and effectiveness – best just to follow your advice and rotate or take a break.
If you use grow bags or containers for alliums and they still get rust, can you pour out the soil, disinfect the containers, and you’re good to go? Or is it just lurking everywhere in your garden now for the next 3 years waiting to pounce w the right conditions?
In containers you can change out the soil and that improves chances of not getting rust again on alliums. We wish the biofungicides were available in consumer quantities, but we haven’t found any readily available since Serenade was taken off the consumer market. We’ll keep looking though!
