What to do when pest infestation is discovered in rose maintenance
Sometimes when raising roses, it is mysteriously found that their leaves are eaten clean within a few days. Today, I will tell you about the culprit. It is this kind of insect, which is very common in summer. The tender branches and buds of roses are eaten up, and it is actually eaten by this kind of insect.
Look at this caterpillar-like larva. This larva is the larva of a stem borer or leaf borer. Stem borers and leaf borers lay eggs inside the branches of the plant. After these insects hatch, they will eat a large amount of the tender branches and leaves of the roses, sustaining themselves for about a week to ten days. After that, these larvae will become adults and fly away.
So we can't find them, and when these larvae are in good lighting conditions, they will hide in dark or hidden places, which are generally difficult to detect. But if you find these larvae, it's not just one or two larvae. The whole leaves and new buds inside will have these larvae, and there will be a large number of them. So when this situation is discovered.
If there are signs of leaves being eaten, you cannot wait and see. We must prepare rose guardians. We find this dinotefuran inside, which is specifically for these insects. It can kill stem borers, leaf borers, aphids, scale insects, thrips, and many other common pests.
We just need to put dinotefuran into a spray bottle, usually diluted with water at a concentration of 100-500 times. Spray the infected leaves with the disease thoroughly, making sure every hidden place is sprayed, as well as the other flowers near the plant.
Because these larvae spread very quickly, they can spread from one plant to another, crawling around, which is very troublesome. Therefore, pest control must be thorough, every corner and every plant must be sprayed, and it can be solved with 2-3 sprays every 3-4 days.
You can see that these insects fall off within minutes after being sprayed and can't crawl anymore. It quickly takes effect within minutes, all fall off and die. This is the effect of dinotefuran. Conversely, if I find it and don't deal with it in time, then within ten days, this flower will be eaten clean.
