波尔多液的发现,可以看作是植物病害化学防治史上第一个重要里程碑,迄今约近一百年.使用化学药剂来防治植病,现已成为作物管理中的必要环节.象水果、蔬菜、烟草、马铃薯、花生、可可、咖啡等作物,若不使用化学农药防治主要病害,商品生产将难以进行;禾谷类、棉花及其他作物的产量也会很低甚至歉收.然而,当今的公众对于所有农药的使用,包括防治植病的杀菌剂在内,都持否定态度.国际植物病理学会化学防治委员会认为,对化学农药防治植物病害当前的技术及其未来在作物生产中的地位作出评价,现在是必要和适时的.
The discovery of Bordeaux mixture can be regarded as the first milestone in the history of chemical control of plant diseases, which has been for nearly 100 years. Using chemical agents to control plant diseases has now become an essential part of crop management. For example, fruits, vegetables, Production of tobacco, potatoes, peanuts, cocoa, coffee and other crops will be hard to produce without the use of chemical pesticides to prevent major diseases; yields of cereals, cotton and other crops will also be low or even poor. Today’s public, however, The use of pesticides, including the control of phytopathogenic fungicides, holds a negative attitude, and the International Phytopathological Society Chemical Control Committee believes that the current status of chemical pesticides for plant disease control and its future status in the evaluation of crop production, and now It is necessary and timely.
