Bacterial Spot Control in Almonds with Magna-Bon CS 2005
Bacterial Spot control in almonds with CS 2005 is gaining strong attention among growers seeking proven, sustainable disease management program. Caused by Xanthomonas arboricola pv. pruni, Bacterial Spot remains a persistent threat to almond production, leading to defoliation, yield loss, and reduced nut quality.
In recent University of California Riverside field trials led by Dr. Jim Adaskaveg, Magna-Bon CS 2005 delivered up to 95% control of Bacterial Spot. The results demonstrate a cleaner, highly effective solution that supports both conventional and organic production programs while helping growers protect yield and crop quality with confidence.
