Rose Thrips Damage and Control
Roses are known for their susceptibility to diseases and pests year-round, especially prone to infections in spring. Neglect can lead to outbreaks. Today, let's share common fertilizer and pesticide damage in roses, as well as the basic characteristics of rose thrips damage.
1. Thrips
Thrips primarily damage the tender buds and leaves of roses, preventing the leaves from photosynthesizing properly. The nutrients in the tender buds cannot keep up, leading to withering and falling off. Thrips are not easily visible to the naked eye. If there are issues with the tender leaves of roses, it is important to address them promptly, otherwise, the later stages will not produce branches or flowers, leading to僵 seedlings. They are generally active during the day and night, so it is recommended to spray in the evening. Pyridine imidacloprid can be used for spraying and control.

If a large amount is applied at once, it can easily burn the seedlings. Of course, tender leaves are more susceptible to leaf burning.

If fertilizer damage is mild, it is necessary to water and flush immediately, continuing to flush several times. The purpose of flushing is to reduce the fertilizer effect. If the damage is severe, remove the pot and flush, then replace with new soil.
3. Pesticide Damage Characteristics
Rose pesticide damage is similar to fertilizer damage, both manifesting symptoms on tender leaves and shoots. Fertilizer damage is characterized by burning and yellowing of the tender leaves, and the tender buds wither and die directly. Pesticide damage, on the other hand, causes curling and greening, similar to sunburn and dehydration, but the tender leaves will not die directly. Therefore, after pesticide damage occurs, you can use brassinolide for spraying and dilution, allowing for a gradual recovery.
