We have been able to prevent both Japanese beetles and SWD 100% in the first year of nutritional foliar treatments when sing sap analysis to balance.

SWD is just straight nutritional integrity. Balance the plants and SWD fails to arrive in your crop even when surrounded with other berry crops with severe SWD.

Japanese beetles seem to respond best to nutrition management, plus strong doses of Rejuvenate foliar fed. We have observed large populations of Japanese beetles disappearing with this type of application.
