The control methods for rose thrips pest
Regarding the issue of rose thrips, there have been preventive tips before, but it has been found recently that many flower enthusiasts are unable to identify the symptoms of thrips. So today, let's talk about the main symptom characteristics of thrips again, which you can compare and handle.
Characteristics of thrips
In this season, thrips are very隐蔽, and you often can't see the thrips themselves, but their damage is very evident.
Many novice flower enthusiasts will be puzzled when told that it's a thrips pest: "But I don't see any pests!"
Thrips that hide during the day and come out at night are hard to see in this season, which is one of the main reasons why many novice flower enthusiasts are confused. Actually, we can judge whether there are thrips based on the symptoms.
Symptoms of thrips pest
Severe thrips damage can leave obvious black scars on the surface of rose leaves, and can also cause leaf deformation and insufficient unfolding.
Severe thrips damage not only leaves scars on old leaves but also causes serious deformation of new leaves, leaf defects, and even rose buds are not spared. Thrips will bore into the rose buds, feeding inside, causing bud deformation.
Therefore, many flower enthusiasts find that the roses in summer are easily deformed and incomplete, and a large part of the reason is caused by thrips.
The above two situations are quite serious, and without preventive measures for thrips pest, they often develop into these conditions. If we have taken preventive measures, the symptoms of thrips will usually be milder, such as blackening of new buds.
At this time, if we apply pesticides promptly to kill the thrips, the new buds of roses can recover and grow. However, if left unattended, blind branches and growth stagnation will occur.
In fact, we can also see signs in the early stages of thrips infestation, such as scars on the new leaves of roses, which are left by thrips damage.
Methods to control thrips
It is impossible to completely eradicate thrips, and we don't need to have zero thrips. As long as we control the number of thrips and prevent them from exploding, the impact on rose growth can be negligible.
It is necessary to apply pesticides every 10-15 days to prevent thrips. Commonly used pesticides include dinotefuran and pymetrozine, which work well for prevention. You can also shallowly bury diazinon in the soil, which also has a good preventive effect.
In addition to applying pesticides, we can also hang yellow and blue boards to trap thrips. This method has a certain effect on preventing thrips and reducing the number of pests.
If you still have severe thrips symptoms despite preventive measures, you need to consider that thrips may have developed resistance. In this case, you should switch to a different pesticide, such as beta-cypermethrin, thiamethoxam, or chlorfenapyr, for insect control. Using a less commonly used pesticide often yields better results.
When thrips are severe, apply pesticides to surrounding plants and potted plants as well. Both the branches and leaves of roses and the soil surface should be sprayed, for comprehensive pest control.
The best time to apply pesticides is in the evening, as the insect-killing effect will be better. If it rains a lot, make sure it doesn't rain within 4 hours after applying pesticides for better results. If it rains within 4 hours after application, reapply the pesticides after the rain stops.
Although thrips are harmful, they are relatively easy to manage. With proper prevention and attention to observation, immediate pesticide application upon detecting thrips damage is relatively easy to control.
