Aphid Control Methods
Compared to what most people know about aphids in the context of flowering plants, let's understand together below.
While beautiful, chrysanthemums are also notorious for being prone to diseases. If your chrysanthemum has already grown new branches, it is essential to take preventive measures against pest outbreaks. This season, aphids are particularly prevalent, especially if no garden cleanup was done in winter. You may now want to check your chrysanthemum; it is likely to have aphids.
Getting to Know Aphids
Aphids, also known as honeydew insects, are found worldwide and are one of the most destructive pests on Earth.
Aphids specifically attach to the new growth, sucking the sap from the tender branches of plants. Not only do they hinder plant growth and cause galls, but they also transmit viruses, leading to畸形 in the flowers, leaves, and buds of the plant. Moreover, aphids secrete a sweet honeydew, which attracts a large number of ants. While the ants feed on the honeydew, they help the aphids ward off their natural enemies, creating a mutually beneficial relationship that allows the aphid population to grow larger.
The reproduction rate of aphids is astonishing. If aphids are detected and not promptly controlled, their numbers will multiply significantly over time. Therefore, immediate action is required upon discovering aphids.
Aphid Control Methods
The control of aphids is relatively simple. When the new shoots of chrysanthemums grow to about 5 cm, it is recommended to use dinotefuran for full-plant spraying. Dinotefuran has an internal absorption characteristic that allows the plant to carry the poison, thus providing good preventive and control effects.
When there are no aphids, dinotefuran can be used for prevention; when there are aphids, it can kill them. It is recommended to use dinotefuran only once a month. If aphids are found again before a month has passed, it is suggested to switch to acetamiprid or pyrethroid insecticides.
If you are growing flowers indoors and find it inconvenient to spray pesticides, you can also use a 100-fold dilution of eucalyptus oil, spraying it on the plant's leaves to achieve a repellent effect.
If you do not want to spray pesticides and also find it麻烦 to spray eucalyptus oil frequently, you can use a small amount of the white insecticide buried shallowly at the edge of the flowerpot. The white insecticide is a slow-release type that can be absorbed by the plant, providing long-term pest prevention and control effects, making it particularly suitable for the prevention and control of pest infestations in potted flowers.
As the weather warms up, it is also necessary to prevent diseases such as black spot and powdery mildew in chrysanthemums. You can add fungicides like carbendazim or zineb to the aphid control spray, which will not only treat aphids but also prevent diseases.
On indoor balconies, you can use both the white and pink insecticides simultaneously to prevent pests while sterilizing and inhibiting bacteria, reducing the occurrence of diseases.
