Symptoms
Symptoms occur in the spring and include chlorosis of the youngest shoot leaves, which are stunted and narrower than normal – ‘little leaf’. Leaf margins are ‘wavy’ and may curl. Yellowing occurs between leaf veins. Blind buds and leaf rosetting can also occur. Extreme deficiency results in shoot defoliation and the production of misshapen fruit.
