花生叶斑病在我省发生普遍,严重的能导致花生提早脫叶,植株变成黑枯状态,影响果实饱滿度,造成减产。作者曾于1957—1959年在霍山和合肥調查,一般春花生于5月下旬开始发病,8月中旬至9月中旬盛发,以后病害不再继续发展。病原菌,初步鑑定为黑斑病菌。連作花生发病重,新茬花生发病輕;夏花生比春花生发病輕;品种之間发病情况无显著差别。防治方法,徐进行輪作和选用无病种子外,主要是药剂防治。波尔多液是目前已肯定能防治这种病害的有效药剂,但是否还有其他有效药剂?为明确这点,作者于1958年在大别山农区試驗站、1959年在安徽省农业科学院作物研究所进行了药剂防治試驗,結果如下:
Peanut leaf spot is common in our province, serious can lead to early leafing of peanuts, plants become black and white state, affecting the fruit fullness, resulting in reduced production. The author investigated in Huoshan and Hefei from 1957 to 1959. Generally, spring flower was born in late May, and mid-August to mid-September. Afterwards, the disease no longer developed. Pathogen, initially identified as black spot bacteria. Even peanuts seriously ill, new crop peanut disease less; summer peanut than spring peanut incidence of light; the incidence of disease between the no significant difference. Prevention and control methods, Xu rotation and selection of disease-free seeds, the main drug control. Bordeaux mixture is now an effective remedy that can surely prevent this disease, but is there any other effective agent? To clarify this point, the author experimented in the Dabie Mountain Experimental Station in 1958 at the Crop Research Institute of Anhui Academy of Agricultural Sciences in 1959 Pharmacy prevention and control test, the results are as follows:
