Identification, Biology, Epidemiology and Geographical Distribution of Fungal and Bacterial Pathogens Associated with Avocados in California
Seven chemicals are presently being tested in field trials and include three single and two combination formulations (Table 1). Field trial one and two are currently set up at South Coast Research and Extension Center (SCREC) in Irvine. Field trial one was set up 03/08/11 and field trial two was set up six weeks later, on 04/18/11. Both trials will be up for three months with trial one taken down starting 05/30/11 and trial two taken down starting 07/11/11. Treated branches Akwill then be pruned out and taken back to the lab where lesions will be measured and the data analyzed.
Biocontrol may provide an effective, long-term, non-chemical, environmentally acceptable method of controlling Phytophthora root rot of avocado through a combination of cultural methods and application of selected microorganisms. This approach will probably be most effective as part of an integrated system of resistant rootstocks, sanitation and cultural methods.
The objective of this project is to educate and inform California avocado growers on laurel wilt disease (LWD) symptoms and the risks of introduction to California. Accomplishment of this objective consists of a two-pronged approach through: 1) developing a collaborative relationship with researchers working on LWD in the southeastern U.S. in order to stay up-to-date on the disease status, and 2) constructing and delivering informational and educational tools and programs through the extension service to stakeholders in the California avocado Industry.
Avocado Branch and Trunk Canker (formerly Dothiorella Canker). In year three of three of this branch and trunk canker study, our objective is to evaluate effective chemical and organic materials to protect pruning wounds in the field from infection by Botryosphaeriaceae and Phomopsis/Diaporthe (P/D) spp.
