Pests and Control Methods

Pests

The insect pests that spider silk rolls on are mostly root mealybugs, a small, oblong insect covered with white wax powder. They can cause the plant to grow weak, the leaves to turn yellow, or even die.

Prevention and treatment methods

You can bury furadan or turbid insecticide in the soil for prevention, and spray avermectin once in summer and winter every year.

You can also use the flower protector to irrigate the roots for treatment.

Planting it outdoors can also prevent root mealybugs to a certain extent.

Diseases and control methods

Diseases

The main disease of spider silk is black rot, which often occurs in summer.

Symptoms include blackening, softening, and eventually rotting of the roots, bottom leaves, or leaf core.

The main cause is an environment that is too humid and hot and has poor ventilation.

Prevention and treatment methods

If you find that the roots or bottom leaves are turning black early, you can dig them out and clean up the rotten roots and leaves. If the stem is rotten, you can cut it off and then place it in dry soil to allow the spider silk to reroot.

If the degree of rot is found to be severe and rot has also occurred in the core of the leaves, then the possibility of survival is unlikely. At this time, it should be dug out and discarded as soon as possible to avoid bacterial infection.
