河南省林园学会于8月20日至24日在西华县国营黄泛区农场,召开了以葡萄、苹果炭疽病为主的果树病虫害学术讨论会。参加会议的有河南省科研、生产和有关院校的园艺及植保工作者67人。中央农业部、中国科学院有机化学研究所、杭州农药厂以及江苏、山东、安徽、河北、山西、陕西、湖北等省有关部门的代表 17人,也应邀参加了会议。 在讨论会上大家一致认为:应用新农药“透习脱”防治葡萄炭疽病具有显著效果。今年在黄泛区农场对36亩季米亚特品种葡萄的大面积防治结果表明,防治区病情指数为0.46,未经防治的对照区的病情指数则为98.25。大家还指出,果园的清洁卫生和植株的通风透光,对减轻和防止病害的发生,也有重要意义。在黄河故道地区,通过各地对葡萄品种的栽培试验,认为生食品种如金后、黑汗、大鸡心、莎芭珍珠、新玫瑰、意大利和酿酒品种如尔卡齐切里、沙别拉维、黑彼诺、佳利娘、黑赛必尔、赛必尔2003、赛必尔2007、巴柯等具有抗病力,各地应因地制宜的发展。
Henan Forestry Park held a symposium on fruit tree pests and diseases with grapes and apple anthracnose as the mainstay in the state-owned Huangfan Farm in Xihua County from August 20 to August 24. There were 67 horticultural and plant protection workers who attended scientific research, production and related institutions in Henan Province. 17 representatives from the Central Ministry of Agriculture, Institute of Organic Chemistry, Chinese Academy of Sciences, Hangzhou Pesticide Factory and relevant departments of Jiangsu, Shandong, Anhui, Hebei, Shanxi, Shaanxi and Hubei provinces were also invited to attend the conference. At the seminar, all agreed that: the application of new pesticides, “through the off” prevention and treatment of grape anthrax has a significant effect. The large-scale prevention and control of 36 mu of grapes in the Yellow River this year showed that the disease index in the control area was 0.46, while the disease index in the non-controlled area was 98.25. We also pointed out that the orchard’s cleanliness and ventilation of plants are also important for alleviating and preventing the occurrence of diseases. In the old course of the Yellow River, through cultivation experiments on grape varieties in various places, it is considered that raw food varieties such as Jinhou, Khan, Big Chicken Heart, Shaba Pearl, New Rose, Italian and wine varieties such as Rakazicheli, , Black Peino, Jialiangniang, black match Bayer, 赛 Bayer 2003, match Seoul 2007, Barco and other disease resistance, all local conditions should be based on the development.
