What to do if chrysanthemums have black bugs
The small black bugs that appear on chrysanthemums are commonly called chrysanthemum aphids, which are a common pest of chrysanthemums. The growth and reproduction of chrysanthemum aphids are relatively rapid, and they can cause certain damage to the plants.
Chrysanthemums develop aphids because of overly dark and stuffy growing conditions, or they may be infected by other plants.
1. Pesticide Spraying
The most effective method to deal with chrysanthemum aphids is to use pesticides for spraying. You can choose to use dichlorvos or Selegue. If the number of aphids is large, you can spray multiple times, about 2-3 times, to remove the aphids.
2. Spraying Soap Water
Prepare some 1% concentrated alkaline soap water, take a small piece of alkaline soap, and put it into a container, then add water in a volume one hundred times that of the soap piece, and stir until the soap is completely dissolved.
Brush the plant with soap water using a brush, as aphids cannot survive in an alkaline environment. After being brushed with soap water, they will die quickly. Repeat the operation of brushing soap water every 3-4 days to kill all the pests on the plant.
3. Using Mosquito Repellent Incense
First, prepare a plate of mosquito repellent incense, light it, and hang it on the branches with aphids, then cover the entire plant with a plastic bag. After熏 for 1 hour, the aphids will be removed.
4. Using Essential Oil
Add a few drops of essential oil to 400 grams of water and stir well. Use it to spray on the plants with aphids, which can effectively kill the aphids.
5. Ventilation
After removing the aphids, it is important to place the chrysanthemums in a well-ventilated environment and remember to open windows frequently to promote air circulation, which can reduce the occurrence of aphids.
【Summary】
The small black bugs found in chrysanthemums are called chrysanthemum aphids, which are easily infected and grow rapidly. The reasons for their appearance may be due to overly dark and stuffy growing conditions or infection from other plants.
