DISEASES
#227 Anthracnose
• Symptoms on infected leaves range from
tiny dead spots to large circular or irregular
dead blotches, depending on the tree
species. Dead areas are black, brown, or
purple.
#228 Apple Scab
• The first symptoms of the disease are
usually found on the underside of
emerging cluster leaves. However,
symptoms may first develop on the upper
side of these leaves in cases where
significant infection was delayed. Young
lesions are velvety brown to olive green
and have feathery, indistinct margins.
#229 Black Spot
• Dark brown or black spots start appearing
on infected plants at the start of the
growing season. The spots appear on the
lower branches and gradually spread
upward.
#230 Botryis
• During wet or humid weather, examine any
brown or spotted plant material that
develops, and look for masses of silvergray spores on the dead or dying tissue.
These spores are readily liberated, and
may appear as a dust coming off of
heavily infected plant material.
#231 Canker
• Spruce trees infected with the Cytospora
canker fungus typically show scattered
branch dieback, often starting on the lower
branches.
#232 Cedar-Apple Rust
• The most conspicuous symptoms on apple
are bright orange, glistening lesions on the
leaves. Lesions which are not inhibited
chemically may form small tufts of sporeproducing structures (aecia) on the lower
surface of the leaf by July or August.
Cedar-apple rust appears on fruit first as
bright orange, slightly raised lesions, but
may take on a more brown and cracked
appearance as the fruit enlarges.
#233 Crown Gall
• Crown gall causes round galls to form on
stems or roots, often near the soil line of
the plant. Galls may vary from the size of
peas to over an inch in diameter.
#234 Fireblight
• blossoms appear water soaked and graygreen but quickly turn brown or black;
generally, the entire cluster becomes
blighted and killed
#235 Powdery Mildew
• Powdery mildew appears as a dusty white
to gray coating over leaf surfaces or other
plant parts. In most cases this fungal
growth can be partially removed by
rubbing the leaves
#236 Root Rot
• Roots are rotted and lack fibrous roots.
After hot, dry periods, older leaves may
wither or become bronzed and scorched.

#249 Iron Deficiency
•
The symptoms of iron deficiency, also known as iron chlorosis, appear in the leaves as green veins and yellow leaf
tissue. If the deficiency is severe, the entire leaf may become yellow. Lastly, brown edges may begin to show up.
Also in severe cases, chlorosis can progress to older growth in the plant.
#250 Leaf Scorch
#251 Nitrogen Deficiency
• Nitrogen is involved in formation of proteins
and plant growth. This nutrient is highly
mobile—in soil and in the plant. Symptoms of
nitrogen deficiency show first in old leaves,
because nitrogen moves from the older
leaves to the newer leaves as the plant tries
to keep growing. The picture of the rose
shows yellowing caused by a nitrogen
deficiency.
