9 Most Susceptible Tree Plant Species
Cambian layers, heartwood, and the inner bark of
stressed woody plants are the entry points of
Botryosphaeria Canker. Once the fungal disease
attacks any trees and plants, it will cut off the
tissues that play a vital role in the
transportation of nutrients and supplements to
the plants. The disruption will be beyond the
infection site. So, what are the clues to
Botrysophaeria Canker infestation? Keep reading
to uncover the symptoms of Canker on afflicted
plants and trees. Damages To Apples/Crabapples Wh
en Canker fungus attacks stressed apple trees,
you will find a minute, reddish-brown spots
around the lenticels. After that, it infects the
twigs and limbs of host plants. Gradually, black
spore- containing fungal structures are on the
surface of the cankers or under the bark. Also,
it will damage the underlying tissues of the
apple and crabapple trees. It is a severe
disease, which you need to identify at the
earliest. However, the internal damage to apple
trees goes unnoticed. So, you need professional
Botryosphaeria Canker treatment to eliminate the
fungal growth and infestation. Outbreak Of Bot
Cankers On Cherries Is something wrong with your
cherry trees? What do you notice at first glance
gummy, resinous ooze, and discolored woods in
the cankered area? If yes, Bot Cankers have
affected your cherry trees. Sunken patches on
the trunk and branches of the cherry trees will
validate the infestation of this fungal disease.
Infected cherry trees may also have brown spots
and empty holes when the center of spots drops
down. It looks like tiny pellets on the leaves of
cherry trees.

Impacts Of Bot Canker Invasion On Honey Locusts
Stem or trunk cankers are the major disease
problem happening to Honey Locusts. To ascertain
the infestation, look for sunken, sparse
foliage, yellow leaves, and premature leaf drop.
When you watch the infected honey locust trees
closely, you will notice cracked yellowish or
reddish color cankers. Canker fungi attacking
honey locust trees are Cytospora, Nectria,
Thyronectria, and Tubercularia. They can cause
too much tissues damage if you delay
Botryosphaeria fungus treatment.
Canker Effects On Pines
Botryosphaeria cankers are an immense threat to
pine trees in your landscape. It reduces the
growth and timber quality degradation wherever
it occurs. Also, it causes lesions that can
encircle or girdle branches, affected roots, and
the main trunk of pine trees. The invasion will
obstruct the flow of nutrition and supplements.
So, the tip of the branches wilts, causing the
needle to turn yellow and then red-brown before
falling from the trees. When the infection
spreads to multiple branch tips, you will notice
dieback in the tree crown. Injuries To
Dogwoods Flowering dogwood trees are also at risk
due to this fungal disease. Improper care is the
major reason for injuries to dogwoods. Also, it
invites other diseases like leaf spots,
anthracnose, and fire blight. The Canker will
girdle the trees over several years. The presence
of Bot Cankers in San Diego is year-round. You
can find them easily when dogwoods are dormant
and have dropped their leaves.

Infection Of Bot Canker On Maples The fungus will
attack the growing layer of maple cells called
cambium. They cause a pronounced bulge of callus
to develop around the infected maples in your
landscape. You will notice the presence of a
swollen, callused trunk. It appears as a sunken
area on the trunk or limb and oozes sap.
However, your maple trees will be susceptible to
the attack of wood-boring insects after the
attack of Bot Cankers. You will observe a large
roughened area of bark, sunken in the center with
heavy callus around the margin. Young cankers
are round to elliptical in shape, hiding behind
the bark. But you dont have to worry about
infection if the maple trees in your landscape
are actually healthy. Yes, the fungus will only
attack the stressed and wounded trees. Canker
Fungus On Oaks It is a fungal disease that
appears as a dead lesion on limbs, branches, and
trunks of affected trees. Initially, Bot Cankers
develop just under the bark. But when the
infection is at an advanced level, it causes the
white-rot and stringy decay of the sapwood. This
decay will compromise the structural integrity
of the tree. You will notice that the leaves of
the infected oak trees will turn yellow and then
brown. The size of the leaves will remain small.
Also, the growth of twigs will reduce. The
damaged oak tree will have a thinner canopy and
dieback of feeder roots. Effects Of Canker
Disease On Elms Canker disease will form on the
twigs and branches of elms. However, leaves on
infected branches of elms turn bright yellow.
Eventually, they will fall prematurely without
wilting. Fungal fruiting structures harden the
bark of infected twigs. Botryosphaeria canker
treatment at the early stage is crucial as the
colonization of canker fungus is slow. Canker
fungi invade only when the elm trees are under
stress. So, you need to know the exact cause of
stress before controlling the spread of Canker.
Tree doctors will identify the stress and offer
precise treatment to revive the health of Elms in
your landscape.

Fungal Canker Attack On Stressed Hollies/Inkberry
Inkberry is a type of holly bush often
susceptible to Bot Cankers. However, it affects
only weaker inkberry plants. The symptoms of
Canker on Hollies are quite similar to root rot.
It includes the yellowing of the leaves and
premature fall. Also, the newest leaves are
usually the first clue to a problem. You will
notice sunken or cracked patches of wood and
girdle the stems. Hence, the nutrients and
supplements cannot reach the leaves. Therefore,
the young twigs may curl downward. Proper care
and treatment are crucial to restrict the damage
due to Bot Canker.
Final thoughts
Botryosphaeria canker is a destructive fungal
disease that can impact a variety of tree and
plant species. Nevertheless, by identifying the
symptoms early and taking preventive care actions
such as pruning, lawn cleanup, and proper plant
nutrition, it is possible to reduce or sometimes
outright eliminate the effects of the
fungus. Original Source Most Afflicted Plants
