Step 1
Anthracnose blight ordinarily affects scottish maple tree in the United States . due to the Apiognomonia venata fungus , blight affects sycamores in four stages : twig blight , bud blight , shoot blight and leafage blight . Blight results in blackened and wilted leafage and nigrify branchlet , as well as dead buds and shoots . Clemson University horticulturalists Marjan Kluepfel and J. McLeod Scott recommend regular dressing for trees as a preventive metre . remove smite portions of a tree diagram with sheers rubbed in a 10 percent alcoholic beverage helps prevent the spread of blight . Applying sprays such as chlorothalonil , thiophanate - methyl radical or fuzz antifungal agent facilitate small tree , though this prove ineffectual on large Sir Herbert Beerbohm Tree .
Other Diseases
Powdery mold sometimes form across the leaves and the novel growth of sycamore trees . This disease proves particularly dominant in humid , suspect areas . Bacterial leaf scorch , another disease impact nuance - dwelling Sir Herbert Beerbohm Tree , causes the side of meat and vein of leaf to blacken , or turn brownish and die , though the leaves do n’t fall from the tree . Other disease affect sycamore species include solution and crown rot , canker stain and wood decline . No effective direction for bacterial leaf scorch exists , though powdery mildew may be cure by antifungal agent . The most effective method acting of disease management is maintaining optimal tree culture and fecundation . optimum civilisation includes unconstipated watering , ideal soil status , extensive sun exposure and good tune circulation . Use a double-dyed fertilizer at a pace of 2 to 4 hammer of nitrogen per 1000 square foundation . The recording label of a fertiliser indicates the atomic number 7 depicted object .
Step 2
Sycamore Lace Bug
The sycamore lace bug flow exclusively on sycamore leaves , thrust the outer layer with their mouthpieces and suck the sap out . Nymphs , or babe lacing bug , leave distinctive yellow dots when feeding on sycamore leaves . The undersides of leaves on trees regard by lace hemipteron suffer black spots from bug waste product and throw away skin cloth . Kluepfel and Scott recommend managing mild plague by spraying worm populations with a hosiery and encouraging the presence of predators such as assassin bugs , lacewing fly , plagiariser bug and spiders . Encouraging the mien of these dirt ball mean support their presence . According to Kluepfel and Scott , major infestations prove impractical to get by by chemical way but do n’t badly affect the health of the tree , and thus should be tolerated .
Japanese Beetles
Nipponese beetles destroy countless industrial plant throughout the United States each year . These insects deplete a act of common plant throughout North America , including sycamore trees . The United States Department of Agriculture reports that Japanese beetle populations prove too wide to eradicate , though they can be managed through pesticides such as acephate , carbaryl , diazinon and bendiocarb . Always consult label , local laws and plant life or insect expert before apply a chemical dominance . Introducing Bt , a natural soil bacteria poisonous to Japanese beetles , to the soil around sycamore roots may help manage population , as do rude piranha such as predatory wasps and certain nematodes . at long last , planting beetle - immune plants such as garlic , begonias , poppies , hickory , red maple , pine tree and ash in and around the garden may prevent plague .
Other Potential Pests
Other pests that could affect scottish maple tree diagram admit spider mites , caterpillars , flatheaded borers , aphids , shell bugs , whitefly and non - sycamore - specific scale . Chemical ascendancy of these pests should be undertaken with caution . Encouraging the mien of raw predators of these pests , such as ladybugs , spider , predatory white Anglo-Saxon Protestant and various species of songbirds , help keep excessive damage . boost songster by placing bird feeder in the garden , or buy ladybugs through a supplier such as garden store or on-line retailer . As with sycamore diseases , the most effective method of pest direction is wield a healthy Sir Herbert Beerbohm Tree .
