medal trees often grow in area where frequent rain , tropic storms , and high level of humidness are the norm . But these environmental component bring to the development of disease that produceblack spotson the palm tree , often defoliate the leaf and — in uttermost scenarios — killing the Sir Herbert Beerbohm Tree .
Graphiola Leaf Spot
Graphiola leafage spot , also commonly refer to as false smut , is bring on by a pathogen of the Graphiola species , and is most rife in palm tree planted in geographical locales where the humidness level is exceptionally in high spirits . The Sabal palmetto , Chinese fan palm , and Washington thenar are among the coinage most frequently affected . The disease manifests on the leaves — frond — of a palm in the form of diminutive , black spots that own the appearance of a wart .
Prevention/Solution
These black spots appear on both side of the leaves and — just like a verruca — are sometimes come with by the sprouting of a small , hair’s-breadth - like structure from within the ontogeny . Young fronds typically display no symptom of the trouble . The rate of transmission from this disease can be denigrate by allowing significant outer space between tree so as to promote good air circulation and thus a reducing in the degree of humidity in the surround air .
Bud Rot
A figure of fungal pathogen of the Phytophthora and Thielaviopsis metal money , in addition to bacterial pathogen , cause the disease refer to as bud bunkum . Symptoms exhibit as dim wound on the buds and young leave of a palm Sir Herbert Beerbohm Tree . Periods of extreme rainwater , particularly tropical violent storm , heighten the likelihood of the ontogenesis of bud rot , while bacterial bud bunk usually occur to fruition when the bud has been injure by cold weather . Fronds will droop and the infected region eventually appear and find vile to the touch .
Bud Rot Management
Mature leaves turn one’s stomach by the disease still stay on green for several month before choke . In extreme causa , the entire Sir Herbert Beerbohm Tree may defoliate , leaving only the trunk remaining . Once bud buncombe attack a palm Sir Herbert Beerbohm Tree , the convalescence of the specimen is unbelievable . The undecomposed prophylactic method acting is to avoid overhead irrigation and never give water to the leaves directly . palm tree trees that are infected with bud bunkum should be removed and ruin to prevent the spreading of the pathogen .
