Evaluation of HLB Treatments
By Stephanie Slinski Evaluating how well bactericides, nutritional programs or other treatments work against HLB can be difficult.

HLB and ‘Tolerance’ as a Practical Matter in Choosing Rootstocks
By Bill Castle (Editor’s note: Click on the graphs throughout the article to enlarge them.)

Grower: Try Fewer Inputs for HLB Before Quitting
Mid-Florida Citrus Foundation grove’s experience of doubled production while cutting expenses in half is not unusual and should encourage some growers to hang on in the face of HLB.
