How to deal with leaf spot disease in roses during summer
Believe it or not, rose growers have definitely heard of a disease called leaf spot disease. Leaf spot disease is highly prevalent during the summer, especially from June to August, which is known as the "three伏days." So during this period, how should we deal with leaf spot disease and how to distinguish it? Let's talk about the issue of leaf spot disease today.
Because this rose plant of mine is infected with leaf spot disease, I will share the details with you. The leaf spot disease in roses is very typical, which manifests on the leaves. You can see this is a typical leaf spot disease, with tiny black spots on it. After the spots appear, the leaves will gradually turn yellow.
Then it will spread to the entire plant, causing black spots all over. Eventually, the plant will constantly shed leaves, and after the leaves fall off, the new leaves that grow will continue to be infected with this leaf spot disease, repeating the cycle over and over again.
However, the plant won't die, but it won't bloom many flowers either. Therefore, the harm caused by leaf spot disease is particularly significant. When we find that a rose is infected with leaf spot disease, we should know how to deal with it.
1. Remove the diseased leaves
Don't keep them, not even one. After removing these leaves, they should not be randomly discarded or left in the garden. Instead, they should be incinerated together because the bacteria inside them can easily re-infect the rose.
2. Clean the leaves
This means cleaning the leaves on the surface of the pot, as there may be hidden bacteria that could spread upwards, leading to a recurrence of leaf spot disease. Now that the leaves have been removed and the leaves on the pot surface have been dealt with, it's time for the third step.
3. Apply pesticides
This disease cannot be cured without pesticides. So what kind of pesticide should you use? Directly apply this "rose maintenance kit" containing azoxystrobin to spray on it. This is a fungicide and is a special product for rose maintenance. Mix it with water and dilute it, then pour it into the spray bottle.
I have already prepared it in advance, shake and dissolve it evenly, and then spray it on the leaves and stems. The entire plant should be sprayed. After spraying the stems and leaves, spray the pot surface again because some leaves may fall on the pot surface, and bacteria can easily invade the pot. It needs to be sprayed on the pot surface. The method for dealing with leaf spot disease in roses is indeed a set.
