Rust on antirrhinum was first recorded in New Zealand from collections gathered in Auckland in December 1953 (Helson, 1953b). Within three years it had spread throughout the country. Baker (1956) described the rust from New Zealand material. Jacks and Webb (1956c) showed that regular sprays with zineb, maneb, or sulphur gave some control of the disease. Close (1958) concluded that as rust-resistant varieties from England became heavily infected with rust when grown in New Zealand, it was the American race that was present in New Zealand. It was probably introduced into New Zealand with debris in seed. In New Zealand, infection has been so heavy that it has limited the use of antirrhinums as a late-spring or summer bedding annual.
