一油橄榄炭疽病在我国各引种点均有发生.但危害程度轻重不一.我们引种的油橄榄,先于1972年秋后发现炭疽病侵害果实,全林病果率约为6%,但当时没有引起我们的重视,至1973年4-5月间,发现贝拉品种春梢陆续枯萎,至6月间病情加重,当年春梢几乎全部枯死,新抽夏梢也开始发病,情况甚为严重,从而使我们认识到,如不迅速查明病原,采取有效防治措施,不但影响当年产量,也将影响到今年及以后的产量.为此,我们在湖北省植物研究所、华中农学院和湖北林业学校的指导和协助下,于1973年7月起,开展了防治试验,至今病情已经减轻,基本上停止了发展蔓延.兹将试验情况作简要的汇报.二油橄榄新梢炭疽病,一般从梢顶端开始,逐渐向下延及整个新梢.初期是叶片退绿,失去光泽,以后向下逐渐枯萎.有时在病斑上可看到波浪式轮纹和粉红色颗粒状的 An olive anthracnose occurs at all the introduction points in our country, but the degree of harm is different.We introduced the olives, first found in the autumn of 1972 after anthracnose infested fruit, the whole forest disease rate was about 6%, but did not cause Our attention, until April-May 1973, Bella found spring wilt gradually withered, to the condition worsened in June, when almost all the spring shoots died, the newly drawn summer shoots also began to attack, the situation is very serious, and thus This will enable us to recognize that if we do not quickly identify the pathogen and take effective prevention and control measures, it will not only affect the current year’s output but also affect the output this year and beyond. Therefore, we conducted a series of research projects at Hubei Institute of Botany, Huazhong Agricultural College and Hubei Forestry School Under the guidance and assistance, in July 1973, started the prevention and treatment test, the condition has been reduced, basically stopped the spread of development .This will be a brief report on the test situation .Two olive shoots anthracnose, usually from the top of the tip Beginning, gradually extending down and the entire shoot. The early leaves green back, tarnished, and later gradually wilt down. Sometimes seen in the plaque wave pattern and pink granule-like
