What should be done if caterpillars are eating the leaves on the rose plant?
The editor will share with everyone the experience of green plant maintenance on what to do if caterpillars are eating the leaves on the rose plant. Let's take a look together!
Since the beginning of summer this year, it has been raining continuously with no high temperatures, so many varieties of roses are still blooming, and they are blooming quite well. Although they are not as beautiful as in spring, their appearance is still acceptable.
Recently, there has been a lot of rain, so there may be fewer opportunities for everyone to spray pesticides, and many gardening enthusiasts think that the flowers of roses in summer are not very beautiful, so they tend to relax their management. However, during this period, it is still necessary to inspect frequently because roses are prone to problems during this time.
For example, during inspections, we often find that the terminal buds of the new shoots of the rose have disappeared and turned into bare stems.
An originally strong terminal shoot is destroyed in this way! This phenomenon of new shoots becoming bald is quite common recently, especially for roses grown outdoors.
Sometimes the situation is a bit better, the tender tips are not damaged, but there are many holes in the leaves, like in the picture below.
When leaves appear like this, our gardening friends know that leaves are definitely being eaten by insects. So, what is the reason for the balding of tender tips?
The balding of rose tender tips is also due to pest damage. It is because insects have eaten the tender buds of the rose flowers, causing the new shoots to become bald and stop growing.
What should be done if caterpillars are eating the leaves on the rose plant?
During this period, many insects will eat the leaves of roses, such as caterpillars, but the most common and camouflaged ones are theGeometer moths, which are the larvae of Geometer moths. They have slender bodies and move in a way that makes their bodies arch like bridges.
Geometer moths can be green or gray-brown and have high camouflage abilities. Now, let's test your eyesight. Can you see which branch has the insect in the picture below? Welcome to leave a message.
When you find that the leaves or tender tips of roses are being eaten, you can carefully look for the larger Geometer moths, which are relatively easy to find. However, the baby Geometer moths are indeed more challenging to detect. They often hide on the underside of leaves, so when searching, you should focus on the back of the leaves.
In addition to carefully examining the back of the leaves, you should also pay attention to the branches and see if there are any "abnormal branches." Because these abnormal branches are highly likely to be伪装ed by insects.
