Key Points for controlling Thrips in Early Summer
A comprehensive introduction to the prevention and control of thrips in early summer for green plants and flowers. The following is a detailed explanation by the editor.
Chojiro flowers have already faded in the first bloom, and those pruned early are now rapidly sprouting new buds, preparing to bear the second bloom. At this time, it is essential to take good preventive and control measures against thrips. If the prevention and control of thrips are neglected, it is likely that there will be no second bloom to enjoy.
Key Points for controlling Thrips in Early Summer
Although thrips are very small in size, they can cause significant harm to chojiro flowers. Thrips feed on the tender branches and buds of chojiro flowers and can burrow into flower buds to feed, severely affecting the normal growth of chojiro. Let's first get to know thrips and their harm.
1. - - Identifying Thrips Symptoms - -
Thrips are very small, only 0.5-2mm, and are pests that hide during the day and come out at night. Their main activity time is at night. Therefore, except for the blooming period, we can see thrips on the flowers. At other times, it is basically impossible to see the shadow of thrips, but the inability to see them does not mean they are not there. So, how do we determine if chojiro has a thrips infestation? We can distinguish from the symptoms of chojiro.
Thrips infestation is a common symptom, and the following four manifestations are summarized for your reference.
① Black new buds and malformed new leaves
Thrips specifically feed on the tender buds and leaves of chojiro. When thrips are severe, the new buds of chojiro can be eaten up by thrips, causing the new buds to turn black, preventing normal germination, or resulting in malformed new bud leaves, twisted leaves, and black leaf tips.
② Brown spots on the leaves
Thrips may also harm the old leaves of chojiro when the new buds have not germinated yet. Therefore, if you find that your chojiro is not sprouting new buds, you should observe the old leaves of chojiro to see if there are brown spots, which may be caused by thrips.

③ Brown spots on flower buds and leaves
After our chojiro flowers have flower buds, thrips will also eat the flower buds of chojiro, causing many brown spots on the surface of the flower buds, and the flower buds will not grow stiffly, especially in summer, this phenomenon is particularly serious. Therefore, whether there are brown spots on the leaves or flower buds, it is necessary to control thrips in time, otherwise, chojiro will become stiff and stop growing.
④ New tender branches with withered and deformed leaves at the top
In spring, after chojiro flowers, it is time to grow new buds and new shoots again. If there are thrips, it often leads to the gradual shrinking of the new leaves of chojiro. If not controlled in time, the new buds will wither and stop growing.

Thrips are most harmful to chojiro in summer, but control should start early. When chojiro is growing the second bloom, it is also when thrips are multiplying in large numbers. Preventive and control measures taken at this time can significantly reduce the number of thrips.
For outdoor chojiro, it is recommended to apply pesticides regularly for prevention and control. The pesticides can be alternated between dinotefuran and beta-cypermethrin, sprayed every 15 days. It is recommended to spray in the evening for better results.
If chojiro is grown on a balcony indoors, it is recommended to shallowly bury a sufficient amount of white medicine in the potting soil for long-term prevention and control. At the same time, hanging yellow sticky traps can also improve the effect of control and has no effect on pets at home.
