干脆以后种菜定期主动喷fungicide

c***p 发帖数: 27645 | 29 我觉得这个黑斑病还算好治,今年成功治好5,6棵,但是我们这里总的来说比较干燥,
你那里潮湿的话会比较麻烦。首先建议花不要种得太密
这个病不会影响开花,但是受感染的叶子会慢慢干枯掉光
先必须把已经受感染的叶子摘掉,摘掉的叶子烧掉或扔垃圾堆,千万不要扔土里,会交
叉感染。
然后去买治black spot的spay,喷!注意叶子背面也要喷到,周围的土也要喷到。
推荐我用的两种spray,效果都不错,我自己更喜欢第二个:
1.Safer Brand 5450 Garden Fungicide
http://www.amazon.com/Safer-5450-Garden-Fungicide-Ready-/dp/B00
这个的主要成分是sulfur
2.Gardener's Choice 3 in 1 Rose and Flower Spray
这个的主要成分是neem oil。这个我是在local 的花店买的,网上没搜到,你如果找不
到,可以买同样成分的spray.
注意这两种成分不同不能混用,要替换到另一种必需间隔至少一个星期。
还有,建议喷药在晚上,挥发慢,不烧叶。间隔3天喷一次。 |
