exportation in Chile totalling about 30,000,000 t each year. A decline
associated with a severe root rot has frequently appeared in 1- to 5-yr-old
kiwifruit vines in the central zone of Chile. Our results demonstrate the
presence of pathogenic isolates of Phytophthora cryptogea and P.
citrophthora associated with diseased plants. This is the first report of
these pathogens affecting kiwi in Chile. They are a potential threat for kiwi
production, particularly in poorly drained soils. |
