What medicine should be used to treat gardenia infested with insects

1. What medicine to use

1. Aphids: Aphids are very common in the growth process. If there are not many of them at the beginning, you can directly catch and kill them manually by pinching them to death with your hands. If the number is relatively large, you can spray a small amount of pesticide to kill the insects. In addition to using chemical agents, you can also collect cigarette butts, soak them in clean water and spray them, which will have less impact on the plants.

2. Scale insects: Remove manually first, scrape them down slowly with a bamboo stick. If you use chemicals, you can use No. 20 petroleum emulsion, add 200 times the amount of clean water, and mix it into a solution for spraying.

3. Mallotus moth: You can use 2.5% diazinon emulsifiable concentrate to spray to kill mallotus moth, which is more effective.

4. If you cannot distinguish what type of pests they are, you can try to kill them manually first and try to remove the pests as much as possible. You can also make your own light salt water for spraying. If the effect is not obvious, you can directly buy Baichongling, which can kill most pests.

2. How to prevent worms

Poor ventilation conditions, stuffiness and humidity are all causes of infestation. If you want to prevent infestation, you can improve ventilation conditions and promote air circulation, which can effectively prevent infestation.
