Tree paint, also known as wound dressing, is any substance applied to damaged surfaces of a tree intended to improve the health of the tree. It is commonly applied after pruning, or at locations where the tree bark has been damaged.〔Juzwik, Jennifer, French, D.W., Jeresek, Jon, Overland Spread of the Oak Wilt Fungus in Minnesota, Journal of Arboriculture 11(11): November 1985 323〕 ==Description== Tree paint may help to prevent disease-carrying insects from entering a wounded tree.〔(A Guide to Successful Pruning, Pruning Deciduous Trees )〕 Studies have shown that wound dressing must be applied immediately after damage or pruning. Even a delay of three days can be too long.〔 White tree paint is commonly applied to citrus trees to keep the affected tissues from overheating, as dark-colored paint can raise the surface temperature of the treated tissues. The classic tree paint is black, because it is based on an asphalt emulsion. Although consumer versions of tree paint may come in spray cans, commercial application may involve paint guns. Tree paint can also applied by brush. An organic tree paint can be made; it is similar to a brushable mud. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tree paint」の詳細全文を読む スポンサード リンク
