自1882年波尔多液作为杀菌剂使用至今,已经有一个多世纪的历史,而且铜制剂发展到现在安全性也更加可靠!尽管品种繁多(硫酸铜、氢氧化铜、氧化亚铜、硫酸铜钙、噻菌铜、喹啉铜等),但是起到杀菌作用的都是Cu+。根据化学构架的不同,安全性、速效性和持效性各有差异。无机铜的速效性高,但是安全性相对较低(如硫酸铜、氢氧化铜等);有机铜的速效性低,但是安全性高(如噻菌铜等)。不过具体的效果与制作工艺有很大关系! Bordeaux mixture has been used for fungicides since 1882 and has been in existence for more than a century, and the safety of copper preparations is now even more reliable! Despite its wide variety (copper sulfate, copper hydroxide, cuprous oxide, calcium copper sulphate, Thiabendazole copper, copper quinoline, etc.), but play a bactericidal effect are Cu +. Depending on the chemical architecture, safety, effectiveness and effectiveness vary. Inorganic copper is highly effective, but less safe (eg, copper sulfate, copper hydroxide, etc.); organic copper is less effective but safe (eg, thiabendazole, etc.). However, the specific effect of the production process has a great relationship!
