2013、2014年对花生叶腐病在山东青岛、日照和临沂等地区的发生情况进行了调查,发现该病害近年在山东部分地区发生严重,尤其是2013年在大部分地区流行成灾。通过对近年来花生叶腐病的发生特点及本省花生生产情况、气象因素、耕作制度、栽培管理要素的分析,认为近年该病害在山东部分地区大发生的主要原因是降雨偏多、偏早,气象条件适宜,加之品种抗病性弱、种植密度过大等。建议今后加强以抗病品种利用为核心,并依据田间发生情况和气象预报,适时采用喷施化学农药作为保障,对该病害进行重点防控。
In 2013 and 2014, peanut leaf rot disease was investigated in areas such as Qingdao, Rizhao and Linyi in Shandong Province. The disease was found to be serious in some parts of Shandong in recent years, especially in 2013 in most areas. According to the characteristics of peanut leaf rot in recent years and the analysis of the peanut production, meteorological factors, tillage system and cultivation management in this province, it is concluded that the main reason for the occurrence of the disease in some areas in Shandong in recent years is that the rainfall is too much, too early, Appropriate weather conditions, combined with the variety resistance is weak, planting density is too large. It is suggested that we should strengthen the use of disease-resistant varieties as the core in the future and make timely use of spraying chemical pesticides as a guarantee according to the occurrence in the field and weather forecast, so as to prevent and control this disease.
