Incidence and Disease Index of Soybean Diseases in the Northeast of China in 2015
In order to clarify the kinds and harmful degree of soybean diseases in the northeast of China,we systematically investigated and identified the pathogen,symptom,incidence and disease index of soybean diseases in the three northeastern provinces in 2015.The results indicated that there were 20 kinds of soybean diseases in the northeast of China.Among them,the most serious damage was soybean root rot,which average disease index of the three provinces was 49.81 and the average incidence rate was 98％.The second popular disease was caused by soybean cyst nematode,the average disease index was 46.53 and the incidence rate was 82.67％.Soybean downy mildew were the most severe leaf diseases,which the average disease index was 33.01 and the average incidence rate was 64％.Also soybean brown spot disease had higher incidence(70％)than other leaf diseases of soybean,but the disease index(18.61) was low.Soybean bacterial angular leaf spot disease was serious in Heilongjiang province,and potentially evolved into a major disease in soybean field in the future.Some diseases such as soybean frogeye leaf spot disease still caused damage in Heilongjiang province.The research here would provide a theoretical guide for sustainable management of soybean diseases in the Northeast of China.
