Such diseases are likely to occur in many species of trees, for example, certain species of the genus Acer, Betula, Populus, Salix in broadleaf trees, as well as certain foreign species Conifers such as Picea abies, Abies balsamea and Pinus strobus and others. In the current world, many countries popularize poplar trees, and our country is no exception. It has risen to a prominent position among afforestation tree species. And Populus many species, hybrids and asexual reproduction have occurred in the phenomenon of heart disease. From young trees to trees, from branches to the trunk and even dry basis can occur. Seriously affected by the entire trunk xylem only by the bark left a circle of white healthy wood. According to incomplete information, Yang’s factions except Populus sentinel and Yew Yew sent the poplar whether the disease is unknown
