Bean rust occurs in the Auckland Province in autumn crops only. Brien and Jacks (1954) stated that it first appeared in commercial crops in April 1951 and became widespread in the Auckland area in autumn 1952. It was also recorded from a private garden in New Plymouth. In some crops foliage was severely damaged, and crop yields were considerably reduced. Resistant varieties of pole bean `Westralia' were introduced from Australia, and the dwarf `Full Green' from U.S.A. Yen and Brien (1960) showed that the bean rust races 10, 17, 28 identified in U.S.A. were present in New Zealand; an unidentified race that attacked the differential line `U.S. 780' was also present in the New Zealand rust material. Yen, Jesson, and Brien, (1962) described a new rust-resistant variety `Mangere Pole', which they had developed for its suitability for commercial growers to sow as a late autumn crop in the Auckland area.
