Bacterial Spot Control in Almonds with CS 2005

Bacterial Spot Control in Almonds with Magna-Bon CS 2005

Bacterial Spot Control in Almonds with CS 2005 is gaining attention among growers looking for proven, sustainable disease management. Bacterial Spot, caused by Xanthomonas arboricola pv. pruni, continues to challenge almond producers—leading to defoliation, reduced yields, and lower nut quality. In recent University of California – Riverside field trials by Dr. Jim Adaskaveg, Magna-Bon CS 2005 delivered up to 95% control of Bacterial Spot, providing a cleaner, more sustainable solution that fits both conventional and organic production programs.
