The plants showed chlorosis and yellowing of young leaves around the bud, necrosis of leaflets in young leaves, necrosis and rot of spears (outer leaf in the process of opening), bending of spears leaves due to the breaking in the lower third, necrosis and internal bud decay which can descend to the meristem and leads to the death of the plants.
