摘要
[ Objective] The paper was to select the effective fungicides to control broad bean chocolate spot. [ Method] Seven different fungicides were selected and sprayed in experimental fields in Jiangsu Yanjiang Area Agricultural Science Research Institute of China in 2012, and yield increase rate and control effect were calculated. [ Result] The control effects of mancozeb 80% WP and pyraclostrobin ＋ metiram 60% WDG against broad bean chocolate spot were 80.88% - 89.26%, and the yield increase rates were 10.85% -41.73%. Mancozeb 80% WP and pyraclostrobin ＋ metiram 60% WG should have beautiful prospect against broad bean chocolate spot owing to excellent control effect and increase yield. [ Conclusion] The study provided reference for field control against broad bean choc- olate spot.
