Since I had the day off and actually had access to a laptop instead of a small cellular phone I decided to study fungicides.Here are some of the active ingredients and some of the most popular brands
Azoxystrobin. Chlorothalonil Copper Sulfate Pentahydrate
I started by making a list of fungicides for anthracnose in stone fruit. I came up with a list of Phyron35. Abound
Amistad . Brovo. Daconil
After studying the active ingredients and how they work. I came to the conclusion that I like Abound but it's a little expensive. Now there are generic alternatives that have the same active ingredient Azoxystrobin 22.9 but don't list all the fruit trees that abound does on their labels as Abound. Abound seems to list anthracnose more often and list mangoes soursop and guava Phyton35 only list things like dogwood Bougainvillea Palm strawberries blackberries and tomatoes does not mention avocado Citrus or mango. Could just be poor marketing
Azoxystrobin is a systemic fungicide used for the protection of plants and crops from harmful fungal diseases. Azoxystrobin is part of a class of chemicals known as ß-methoxyacrylates, which are derived from the naturally-occurring compounds and are used mostly in agricultural settings. At this time, Azoxystrobin is the only fungicide with the ability to offer protection against the four major types of plant fungi.
Azoxystrobin was first discovered in the midst of research being conducted on fungal mushrooms commonly found in the forests of Europe. These small mushrooms fascinated scientists due to their strong ability to defend themselves.
It was found that the defense mechanism of the mushrooms were based on the secretion of two substances, strobilurin A and oudemansin A. These substances gave the fungi the ability to keep their competitors at bay and kill them when in range. Observations of this mechanism led to research that resulted in the development of Azoxystrobin fungicide
This is my first day of really studying this but I do see they say that FRAC group 11 fungicides have a risk of resistance developing and should be tank mixed with a low-risk protective but I do not know if that's true for Abound. Any assistance or input would be extremely appreciate it.
Azoxystrobin 22.9

I can only find two articles on this subject

However, in field studies, azoxystrobin is degraded quite rapidly in soils with a half-life of 1 to 5 weeks. Both photodegradation and, to a lesser degree, microbial metabolism are involved in its dissipation since the compound is relatively stable to hydrolysis. The half-life for photolysis in soils is in the range of 11 to 15 days depending on nature of the soil, azoxystrobin has a low to moderate potential for mobility in soil, but little movement down the soil profile was seen in field studies
