Common Pests of Teyu Lotus and Their Control Methods

Common pests of Teyulian: root-knot nematodes

Root-knot nematodes mainly harm the roots of the Jade Lotus, which manifests as an increase in lateral roots and fibrous roots compared to normal, and the formation of spherical or conical white nodules of varying sizes on the fibrous roots of young roots, some of which are rosary-shaped. The upper part of the affected plants grows short and slow, and the leaf color is abnormal, and in severe cases it may even cause the death of the plant.

Prevention and control methods: prevention first, comprehensive prevention and control.

Using Yiwei Shuangjia's wireless bottom application, throwing application, or Kexianbao to mix with seeds, dip in roots, water seedlings, and flush application, or using JT compound bacteria mixed with fine soil and spread before seedlings and then turning the soil, can effectively reduce the occurrence of nematodes, inhibit the pathogens carried by nematodes, and improve the root environment.

After an insect infestation occurs, remove the insect remains and spray pesticides. The medicines you can choose include Miler, Yishubao, etc.

Common pests of Teyulian: scale insects

The main insect pests are scale insects. More than 80% of the plants bought from flower markets and other places have scale insects on their roots. Initial infestations are usually found at the roots or in the center of the plant.

Prevention and control methods: After discovering the pest, it is necessary to immediately isolate it from other plants, cut off the roots that breed scale insects, and spray the affected area with Flower Protector or irrigate the roots to kill them (fungicides such as thiophanate-methyl and carbendazim do not have insecticidal effects). It may take several cycles to completely kill scale insects. For prevention, a small amount of furadan or carbofuran can be mixed into the soil.
