How to treat and what medicine to use when thrips are found on roses
Let me share with you some knowledge about rose cultivation when thrips are found and what medicine to use. The following is a detailed explanation by the editor.
When roses are invaded by thrips, the following measures can be taken for treatment and corresponding medicines can be used.
Physical control:
Remove infected leaves: When yellow spots or twisted deformation caused by thrips are found on rose leaves, the damaged leaves should be promptly removed to reduce the breeding and food sources of thrips.
Cut off severely affected parts: For severely affected branches, they can be pruned appropriately to promote new bud growth.
Chemical control:
Use imidacloprid: Imidacloprid is a broad-spectrum insecticide that is effective against thrips. When spraying, make sure to spray both sides of the leaves, usually one spray can significantly reduce the number of thrips.
Acetamiprid: Acetamiprid is also an effective insecticide that can be used to control thrips. When using, make sure to spray evenly, especially in the evening or at night when thrips are active, to improve control efficacy.
Other insecticides: Insecticides such as skin insecticides, mefenpyr-diethyl, and aktar can also be chosen based on the actual situation and symptoms.
Comprehensive management:
Strengthen fertilization and water management: Promote healthy plant growth and enhance resistance to thrips.
Clear field weeds and withered branches and leaves in early spring: Incinerate or bury them deeply to eliminate overwintering adults and nymphs, reducing the overwintering population of thrips.
When using chemical agents, be sure to follow the recommended dosage and method as indicated in the product manual, pay attention to the safety interval, and avoid adverse effects on the environment and human health. Also, observe the therapeutic effect and, if necessary, continue to spray several times until the number of thrips is completely controlled. If you do not want to use chemical agents, you can also control the invasion of thrips through physical methods, such as cutting off the affected parts.
