Grape scale insect damage

The damage caused by grape scale insects mainly manifests as the nymphs and adult females absorbing sap from different parts of the plant such as buds, leaves, and fruits. Usually, the tender branches and roots are more severely affected, leading to swelling, longitudinal cracks, and eventual death. In later stages, it can also trigger sooty mold, causing fruit rot.

Causes of grape scale insects

The causes of grape scale insects may be due to a humid environment or improper care methods during maintenance, without regular checks on the plant's growth, which can lead to their appearance.

Grape scale insects can be effectively treated. Generally, when the insects have crawled out of their shells, it is a good time to spray the pesticide. Thiazalone and dinotefuran can be used. If pyridaben is used, attention should be paid to the temperature sensitivity of the insecticide.

Methods for preventing and controlling grape scale insects

1. Treatment methods for scale insects

When scale insects are severe, they can overlap densely, weakening the tree's vitality. If not treated in time, it usually takes 3-5 years to destroy the entire orchard. For treatment, a solution of lambda-cyhalothrin, matrine, flonicamid, and pyridaben can be made for spraying, which can achieve radical cure.

2. Preventive measures for scale insects

The best time for preventing and controlling grape scale insects is around Labor Day, after the first light rain, which is before the grapes bloom. The effective component is螺lufenuron. If combined with fast-acting products, the effect is better. Additionally, lufenuron can be used to spray the severely affected areas before and after flowering.
