[ 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.展开更多

It is a multi-purpose crop that plays an important role in the socio-economic life of farming communities in Ethiopia. Chocolate spot disease, caused by Botrytis fabae is one of the yield limiting factors of this crop resulting in yield losses up to 68% in Ethiopia. A field survey was conducted in Tach Gayint district South Gondar Administrative Zone during the 2020/2021 main cropping season to assess the importance of the chocolate spot disease of faba bean. A total of 60 faba bean farmer fields were assessed in six (6) Kebele Administrations and most farmer fields were affected by chocolate spots. But the status of disease incidence and severity was varied. Significant differences among locations were observed due to altitude, soil type, planting density, date of planting, crop growth stages and farm history of the fields. Independent variables like Altitude, farm history, crop growth stage, date of planting and planting density were significantly associated with both disease incidence and severity when entered first and last into a model. The finding indicates that the lowest plant density and late planting of the crop reduce the incidence and severity of the disease.展开更多
