Non-fungicidal control strategies for Phytophthora cinnamomi root rot of avocado
While fungicides may be a major mechanism for control of avocado root rot, integrated management requires several other non-fungicidal approaches which are used together to maximize root rot control. Non-fungicidal methods of control include planting clean avocado nursery stock, selecting low hazard sites, planting on mounds in more hazardous sites, preventing the introduction of P. cinnamomi, ...
متن کاملPlant growth-promoting rhizobacteria associated with avocado display antagonistic activity against Phytophthora cinnamomi through volatile emissions
Rhizobacteria associated with crops constitute an important source of potentially beneficial microorganisms with plant growth promoting activity or antagonistic effects against phytopathogens. In this study, we evaluated the plant growth promoting activity of 11 bacterial isolates that were obtained from the rhizosphere of healthy avocado trees and from that of avocado trees having survived roo...
متن کاملEffects of Gypsum Soil Amendments on Avocado Growth, Soil Drainage, and Resistance to Phytophthora cinnamomi
Phytophthora root rot of avocado, a soilborne disease caused by Phytophthora cinnamomi Rands, continues to be devastating to the cultivation of avocados despite more than 70 years of research on control methods. Phytophthora root rot has been estimated to be present in two-thirds of the avocado groves in California, causing losses of almost 30% of the total value of the crop (5). P. cinnamomi m...
متن کاملQuantifying the Severity of Phytophthora Root Rot Disease in Avocado Trees Using Image Analysis
Phytophthora root rot (PRR) infects the roots of avocado trees, resulting in reduced uptake of water and nutrients, canopy decline, defoliation, and, eventually, tree mortality. Typically, the severity of PRR disease (proportion of canopy decline) is assessed by visually comparing the canopy health of infected trees to a standardised set of photographs and a corresponding disease rating. Althou...
متن کاملRapid Immunological Tests for the Detection of Phytophthora Cinnamomi in Avocado Roots
We will first prepare reference antisera to total proteins of P. cinnamomi and P. citricola. The protein profile of each fungus will be analyzed by SDS-Polyacrylamide Gel Electrophoresis(PAGE). By this procedure, fungal proteins are driven by an electric current and are separated into bands in a gel medium. The distance of the movement of each protein is dictated by its size. The protein bands ...
