Don't spray carbendazim on gardenia pests, this is the right way to handle them

How do you save a gardenia once it gets pests?

Looking at your problem description, you said you sprayed carbendazim and it didn't work, so how should you treat it?

Looking at your picture, in your case you've got aphids. If you go and spray carbendazim, it won't do a thing. Even if you spray it ten times, these pests will only multiply more and more. Carbendazim is not an insecticide, it is a fungicide, able to play a sterilising role, mainly preventing bacteria from breeding. Carbendazim is generally used to prevent plants from developing rotten leaves, sprayed on in advance as a protective measure. If a plant has wounds or cuts, you can apply carbendazim to prevent rot. So using carbendazim is wrong.

The pests on yours. Spraying them with ordinary chemicals can solve the problem very well. For example acetamiprid, imidacloprid and Huhuashen are all fine. You must choose an insecticide to kill insects, do not choose carbendazim, mancozeb and the like, these are all fungicides, and using them to kill insects has no effect at all.

You can choose imidacloprid. When spraying, spray the front and back of the leaves as well as the branches and stems, and also spray the surface of the potting soil. Generally, spraying twice is about enough, and spray a third time as a protective measure. Afterwards they won't appear again.
