What are the little black bugs in chrysanthemums and how to get rid of them

1. What is

The small black insects that appear in chrysanthemums are called chrysanthemum aphids. They are pests that grow and reproduce very quickly. Chrysanthemums are easily infected. If left unattended for a period of time, a lot of them will grow and bite the leaves and buds, affecting flowering. The reason for this may be that the growing environment is too dark and hot, making the plants prone to breeding pests. If they are grown outdoors, they may be infected by other plants and need to be dealt with in a timely manner.

2. How to remove

1. Spraying with pesticides: The most effective way to remove pests is to spray with pesticides. You can choose DDT, chlorpyrifos, cypermethrin, etc. If the number of pests is large, you need to spray more times, and it can be removed after 2-3 times.

2. Fumigation with mosquito coils: Prepare a plate of mosquito coils, light it and hang it on the branches where insects are infested. Then put on a plastic bag to cover the entire plant. The aphids will be removed in about an hour.

3. Wind oil: Add a few drops of wind oil to about 400 times the concentration of clean water and use it to spray the plants to kill aphids.

4. Pay attention to ventilation: While removing chrysanthemum aphids, you should also pay attention to the ventilation environment, open windows in time to promote air circulation.
