Symptoms:

• Young plants can be stunted.
• The terminal bud of plants at various ages can be bent over to form a characteristic hook, and buds may become brown and fall off.
• The pith may develop a brown discoloration, and leaflets may be smaller than normal and may deform by cupping.
• Pods may have brown patches and may develop poorly and abort.
• Maturity can be delayed and plants may remain green until frost.
