What should be done about the damage caused by chemicals on roses?
Let me share with you some experience on the green plant maintenance aspect of dealing with chemical damage on roses, the specific details are as follows:
Yesterday afternoon, I took a nap and when I woke up, I found dozens of messages on my phone. Most of them were about the yellowing leaves of roses and problems with pests and diseases. These are common issues, but there is one problem that is not very common but has become quite common this year. What is this problem? Let's take a look together.
Doesn't this leaf look very beautiful? It looks like a variegated succulent plant, but this kind of beauty is actually a pathological beauty!
However, most of the time, it does not show such a beautiful pathological condition, but rather deformation, spots, and沧桑 are more common.
Actually, this kind of manifestation is very typical of burn damage, which usually occurs 3-5 days after spraying pesticides or foliar fertilizers, which means it is actually a manifestation of chemical or fertilizer damage.
Roses are prone to pests and diseases, which is a well-known fact. But in fact, this year's pests and diseases are particularly severe. In this case, many rose enthusiasts can't help but use strong measures when applying pesticides, but often after applying pesticides, this kind of damage to the leaves occurs.
What should be done if chemical damage occurs?
1. Pay attention to prevention
Both chemical and fertilizer damage are irreversible, so treatment is more important than prevention. Therefore, when applying pesticides, try to use a slightly lower concentration than the recommended ratio. Flowers are usually more delicate than crops, and it's better to apply a small amount multiple times. Especially when roses have a large number of new branches and the leaves are red, more attention should be paid to reducing the concentration when applying pesticides and fertilizers.
Old green leaves are usually thicker-skinned and more resistant to chemicals and fertilizers. Therefore, chemical and fertilizer damage often occurs first on the new tender leaves.
What should be done about the damage caused by chemicals on roses?
If you feel that the concentration is too high after applying pesticides or fertilizers and feel uneasy, then the Green Plant Enthusiast Network suggests that you water thoroughly after 4-6 hours. If there are a lot of chemicals left on the leaves, water more to avoid just wetting the leaves. Otherwise, the remaining chemicals will be absorbed again, increasing the risk of chemical damage.
Also, if you are raising roses outdoors, choosing to apply pesticides in the evening can also prevent chemical damage to some extent because there will be dew at night.
2. Use Detoxifying Agent promptly
After applying pesticides or fertilizers, pay attention to observation. If there is chemical or fertilizer damage, there will be some manifestations the next day to 3-5 days later. If any abnormalities are found, immediate treatment is required to minimize the damage.
You can use a Detoxifying Agent to spray on the leaves or pour it into the roots to mitigate further development of the chemical damage.
The Detoxifying Agent is actually a fertilizer and does not neutralize the effect of chemicals on roses. Instead, it regulates the growth of roses to help them metabolize the remaining chemicals, allowing new leaves to grow normally.
Therefore, when using the Detoxifying Agent, also pay attention not to use it excessively, otherwise, not only will the chemical damage not be resolved, but it may also cause fertilizer damage, which would be counterproductive. So, when using it, the concentration should be lower than the recommended concentration, and it can be used in small amounts multiple times for safety.
