Bee-safe fungicide for brown rot? #874296
Asked June 23, 2024, 1:57 PM EDT
The article about brown rot in stone fruit trees was very helpful. Several fungicides were listed at the end of the article as being effective in fighting brown rot when used in combination with cleaning and pruning. I looked up each fungicide and learned that all of them are toxic to bees. Is there a known fungicide that is effective against brown rot without endangering pollinators?
