• Later, depression due to boron deficiency becomes very marked and plants show death of the apical bud of the shoot which leads to development of several auxiliary branches.
• Leaves are thick and brittle and the size of the leaves is reduced.
• Pod formation and seed development are severely reduced by boron deficiency.

Chemical control

• Spray 0.1-0.2% borax or boric acid solution at weekly intervals.
