For detailed information on management of blueberry problems, consult the Highbush Blueberry Production Guide published by NRAES. Specific pesticide and fertilizer recommendations vary by state (e.g. Cornell Pest Management Guidelines for Berry Crops - 142RSF).

Positive identification of fungal pathogens and nematodes can be obtained through the Cornell Plant Disease Diagnostic Clinic or your state university.

Suspected nutrient deficiencies can be verified with a foliar analysis.

Return to the Diagnostic Tool.

Much information exists on controlling plant pests and problems, but one must first identify the problem before intervention can occur. This diagnostic tool was developed by Dr. Marvin Pritts to assist the student, grower, and extension educator in identifying potential causes of plant problems in berry crops.

The photographs used in the diagnostic tool are owned by others, and are for educational purposes only. They are not to be used for any commercial purpose, or reproduced in any way, without permission from NRAES.
