在杀菌史上,波尔多液是人类最早发现和应用的保护剂之一。它杀菌力强,防病范围广,药效持久,病菌不会产生抗性,对植物安全,对人、畜低毒;另外,微量的铜还能促进植物叶绿素的形成,刺激生长。所以波尔多液是生产无公害农产品的首选杀菌剂。 In the history of sterilization, Bordeaux fluid is one of the earliest discovered and applied protective agents in humans. It has strong bactericidal power, a wide range of disease prevention, long-lasting drug efficacy, no resistance to pathogens, low toxicity to humans and animals, and a trace amount of copper can also promote the formation of chlorophyll and stimulate growth. Therefore Bordeaux liquid is the preferred fungicide for the production of pollution-free agricultural products.
