Production of asparagus (Asparagus officinalis L.) is globally constrained by the “early decline” syndrome. The primary causal agents of early decline include Fusarium proliferatum (Matsushima) Nirenberg, F. oxysporum Wollenw. f. sp. asparagi S.I. Cohen, and F. subglutinans Wollenw. & Reinking. These pathogens together contribute to Fusarium crown and root rot (FCRR). Damage to asparagus stems, especially by the asparagus miner (Ophiomyia simplex Loew [Diptera: Agromyzidae]), has been associated with and shown to exacerbate FCRR. This review synthesizes the current information on this tripartite interaction, describes management strategies and their efficacy, and highlights needed research. Opportunities for future control of the asparagus miner and associated FCRR are presented. Research areas of interest include investigating the role of semiochemicals in the asparagus miner–Fusarium spp. interaction, identifying effective biological controls for the asparagus miner, and determining source populations of asparagus miner in new asparagus plantings.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
