Boron deficiency (B)
Boron deficiency symptoms are only rarely visible on maize. Boron deficiency may be expressed by foreshortened internodal growth and by narrow white and transparent necrotic spots. Acute boron deficiency will cause young leaves to become brittle, to twist and to produce wrinkled leaf tips.
A lack of boron will result in smaller cobs, with less tightly packed kernels. Kernel rows will appear less regular.
Foliar application of EPSO Microtop® (0,9% B) will meet the nutrient requirement for maize, and will prevent boron deficiency.
