What is growing at the base of this peach tree? These are mushrooms from the fungal root disease Armillaria Root Rot (Armillaria spp.). This soil-borne disease is of major concern for the stone fruit industry as it causes premature tree decline. There are currently no resistant rootstocks available. Therefore, cultural control methods, like planting on berms and using root collar excavation, are the best tools we have to combat the issue. Another thing for growers to consider is leaving known armillaria sites fallow before replanting in peach trees, although, this can be very difficult with the availability of land. Check out the Armillaria Root Rot Solutions Blog to learn more about the work being done to address this disease.
