Boron Deficiency of Solanaceous Crops
Return to Physiological and Nutrient Disorders
Boron deficiency in potatoes results in necrosis (dieback) of the tuber tissue. Use boron-containing fertilizers to correct deficiencies. Be cautious to not over-fertilize with boron as it is a micronutrient, and much lower levels are necessary to correct deficiencies than with macronutrients, such as nitrogen, potassium, and phosphorus.
