What symptoms will roses have after being infected with red spider mites and thrips?
Hello everyone, in the summer, it is most common to encounter leaf mites and the damage caused by thrips when raising roses. Today, I will briefly talk about the main manifestations and initial symptoms after being infected with these pests.
1. Infected with thrips
If your roses are infected with thrips, the tender branches and leaves will show this kind of inexplicable burnt edges, and the wilted leaves look like they have been burned, gradually withering from the edges. These leaves cannot grow large or expand, and many leaves are like this. This is definitely infected with thrips.
Thrips forage at night, gnawing and sucking the nutrients and moisture from the tender branches and leaves of roses, which leads to the loss of sap, causing these new leaves to fail to expand and show burnt edges. This phenomenon will gradually lead to leaf shedding and withering, and the new buds will also die.
After being infected with thrips, we can use a product called Dinotefuran in the "Rose Guardian." We should spray it at night when there is no light because that's when thrips come out to forage. Dinotefuran should be sprayed every 3 to 4 days at night and can effectively kill all the adult thrips. Two or three treatments can solve the problem.
2. Infected with leaf mites and red spider mites
When roses are infected with leaf mites and red spider mites, the symptoms are also very obvious. First, the tender branches and leaves show yellowing leaves with green veins. In severe cases, these leaves are slightly yellow but have many tiny yellow or slightly red dots.
To eliminate red spider mites and leaf mites, we can use a product called "Rose Guardian" which contains a substance called螺螨酯 (luo mian zhi). It is very effective in killing red spider mites and leaf mites. Two or three applications can effectively suppress and prevent further infection.
These two types of pests are commonly encountered when raising roses in the summer. I hope these methods can help everyone. See you next time!
The above is an introduction to the symptoms that roses will have after being infected with red spider mites and thrips, which can be used as a reference for everyone.
