![]() ![]() In accordance with Federal civil rights law and U.S. With that, we abide by the USDA Nondiscrimination Statement: TACF receives grant funding from the USDA. In addition to improving disease-resistance, TACF and its affiliates are working to conserve the genetic diversity of the species, assess susceptibility to other pests and pathogens (in addition to chestnut blight), and to understand the ecology of the species in order to prepare for landscape-scale reintroduction. No matter the method, whether used independently or in combination, the goal is to produce American-type chestnuts capable of surviving and reproducing in the forest unassisted. American Chestnut Research and Restoration Project at SUNY ESF.Transgenic Darling 58 American chestnut tree facts.TACF’s NY Chapter, in affiliation with SUNY-ESF, are working to create a genetically modified American chestnut. In addition, efforts are made to increase the range-wide genetic diversity of this growing population of trees. Requiring a minimum of six generations of breeding, progeny from this program are selected at each generation to exhibit American characteristics and some level of blight resistance. The majority of TACF staff and volunteers are involved in a traditional breeding approach. In severe cases, horse chestnut trees may succumb to this disease.TACF engages in a multi-pronged effort to create a disease-resistant American chestnut, including traditional breeding techniques, genetic modification, and reduction of fungal virulence. Canker causes the bark of the tree to “bleed” a dark colored secretion. Horse Chestnut Bleeding CankerĬaused by bacteria, bleeding canker of horse chestnuts is a disease that impacts the health and vigor of horse chestnut tree bark. Though it has not shown to cause serious damage to horse chestnut trees, it may be of some concern, as infected leaves may fall prematurely from trees. The tiny caterpillars create tunnels within the leaves, and eventually cause damage to the plant’s foliage. Horse chestnut leaf miner is a type of moth whose larvae feed on horse chestnut trees. Destroying the infected plant matter will help to better control future leaf blight infections. While there’s no treatment for leaf blight in the home garden, you can help to combat the issue by removing infected leaf litter from the garden. Leaf blight most often results in premature loss of leaves from trees in the fall. Wet weather in the spring allows the adequate moisture needed for the fungal spores to spread. Often, these brown spots will also be surrounded by yellow discoloration. Leaf blight is a fungal disease which causes large, brownish spots to develop on the tree’s leaves. One of the most common diseases of horse chestnut trees is leaf blight. By familiarizing themselves with signs and symptoms of decline in tree health, growers are better able to treat and prevent disease of horse chestnut trees. The severity of horse chestnut diseases may vary greatly depending upon the cause. Like many types of trees, diseases of horse chestnut trees may arise due to insect pressure, stress, or less than ideal growing conditions. Though relatively simple to grow, there are several common issues which lead to the decline of this plant’s health – issues that may cause growers to ask, ‘is my horse chestnut sick?’ What’s Wrong with My Horse Chestnut? In addition to providing welcome shade during the hottest parts of summer, the trees produce large and showy flower blooms. ![]() Much loved for their use in landscaping and along roadsides, horse chestnut trees are now widely distributed throughout Europe and North America. Horse chestnut trees are a large type of ornamental shade tree native to the Balkan peninsula. ![]()
