Common pests and control methods of ground root

Common pests and control methods of ground root

aphid

Aphids are a common disease of bonsai plants grown at home. They suck the sap from the leaves and harm the health of the plants. Aphids cannot be removed manually like other pests, so some pesticides or physical treatment methods are often required.

Prevention and control methods: physical removal.

Soaking orange peels in water is a very good physical method to clean aphids. It is effective and environmentally friendly.

Add two drops of detergent to a cup of orange peel water, about 700 ml, pour it into a spray bottle, shake well, and you can use it.

Aphids generally grow in the axils of new leaves and branches, so you should mainly spray the branches close to the potting soil, spray thoroughly, and then spray on the leaves.

Scale insects

Scale insects are very annoying pests. They have hard shells and are resistant to common pesticides, which often harm the plants that have taken root but do not affect them at all.

Prevention and control methods: The pesticide is not important, the time of spraying is the key.

Because the shells of adult scale insects are very hard, the effectiveness of pesticide application is often reduced. Although many pesticides can prevent and control scale insects, such as cypermethrin, etc., the best effect is to spray them when the scale insects are one year old!

Keep the habit of checking for pests. If you find scale insects within 1 to 3 days, they will be in the first age stage. At this time, buy pesticides and spray them to kill them in the cradle and prevent them from doing harm.

Dark Grey Butterfly

Although the black gray butterfly is very beautiful after it breaks out of its cocoon, it is a very serious pest when it is still a larva! It sucks the leaves and branches of the plant, and even turns its little pink body green. It's really intoxicating!

Prevention and control methods: Manual removal with insect-proof nets.

The larvae of the black grey butterfly can burrow into the leaves and suck their food, which is very annoying. So once found, it should be cleared manually in time. Even cut off the branches and leaves where the larvae are found to prevent other insect eggs from hiding in between.

Because the plants can grow very large, there are always corners that are missed during inspection. The best way is to put up an insect-proof net to avoid the black gray butterfly!

The best way to prevent pests is to take precautions before they occur. Many drugs buried in the soil can directly prevent the breeding of insects, such as furadan.
