Summary:
States within the southern agricultural region of the United States are among the top producers of tree fruit, grapes, and small fruit nationally. Excluding California fruit production, total utilized value of cultivated blueberry, peach, and strawberry from states in the southern region represented 31.0, 97.4, and 96.8% of the US utilized value of these crops in 2016. Despite high fruit annual fruit yields, achieving sustainable management of diseases in fruit crops is a constant challenge due to the subtropical and tropical climates of the southern agricultural region. Diseases of fruit crops that are caused by fungal species in the genus Colletotrichum are among the most economically devastating and challenging to manage throughout the region. Direct losses of fruit, just prior to or after harvest, result from the development of anthracnose rots on fruit. In addition, infection of leaf, root, and crown tissue by the pathogen is increasingly resulting in indirect losses throughout the Southeastern US. These losses include compromised photosynthesis due to premature defoliation, reduced winter hardiness and bud-set, and plant death. In the absence of effective management interventions, single-season losses often approach 100%.
The formation of a new working group to address integrated strategies for the management of Colletotrichum diseases on fruit crops in the Eastern US is proposed. The goal of this working group will be to conduct research and extension planning to improve stakeholder practices of managing fruit diseases caused by Colletotrichum spp. in the eastern US. Specifically this proposal will aim to define extension and research priorities for management of diseases caused by Colletotrichum on fruit crops, coordinate research and extension activities across hosts and scientific disciplines, develop and disseminate a uniform multi-crop survey to stakeholders to identify knowledge gaps and assess current management programs and prepare a proposal(s) for a collaborative approach to managing Colletotrichum spp. on fruit crops in the Eastern US. Administrative note: The funds awarded for this project were not spent. Objectives: Obj. 1. Organize a multi-state team of stakeholders that includes academic and USDA researchers and extension specialists, extension agents, crop consultants, and growers that will work together to develop integrated strategies for the management of diseases of tree and small fruit caused by Colletotrichum spp. a. Facilitate communication of current research and extension activities being conducted across different tree fruit and small fruit hosts and initiate coordination of Colletotrichum-focused research activities b. Develop a list of extension and research priorities for management of Colletotrichum on fruit crops in the eastern United States c. Develop plans for grant submission for a) Continuation of this IPM working group in 2020, and b) Regional and Federally funded grant programs including Southern SARE, USDA-AFRI, and SCRI Obj. 2. Assess stakeholder knowledge of management of diseases caused by Colletotrichum spp, current management practices for fruit diseases causes by Colletotrichum spp., and the economic inputs and losses due to Colletotrichum diseases in the Eastern US a. Disseminate surveys at field days, on extension portals/websites, and grower schools/meetings using a combination of written surveys, on-line surveys, and clicker-based surveys. |
