Molybdenum deficiency

Left: healthy leaf receiving molybdenum. Right: Molybdenum deficient leaf; leaflets, incurled margins, intervenal chlorotic motting and death of tips.

Molybdenum deficiency

Leaflets somewhat chlorotic, strongly incurled and die back from tips.

Boron deficiency

Fruits pitted and corky areas in skin; ripening uneven.

Boron deficiency

Stems stiff; terminal buds die and growths die back; lateral shoots developed, giving plant flat top; leaves highly tinted purple, brown and yellow.

Manganese toxicity

Stem and petioles, especially nodal areas, necrotic lesions; leaves wither and hang down.

Manganese deficiency

Intervenal chlorotic mottling distributed over entire surfaces of leaflets; mottled areas become necrotic. (cf. Plate 261, iron deficiency)

Iron deficiency

Tip leaves, especially basal areas of leaflets, intense chlorotic mottling; stem near tip also yellow. (cf. Plate 262, manganese deficiency)
