Common diseases and pests of Axeleaf Peperomia

Diseases

A common disease of Axe-leaf Peperomia is leaf spot. The symptoms of leaf spot disease are: oval, long, light reddish-brown spots on the leaves, surrounded by chlorotic circles, which later expand into large irregular patches with black spots on them.

The leaf spot pathogen overwinters in diseased debris or on the surface of potting soil, and spreads with wind and rain to infect plants during the disease period the following year. It is easy to occur in greenhouses in all seasons. Excessive planting density, poor ventilation and excessive humidity can easily lead to disease.

Pests

A common pest of axe-leaf peperomia is scale insects. Once attacked by scale insects, the leaves will turn yellow, the branches will wither, the plants will decline, and it is easy to induce sooty mold disease.

Scale insects have strong reproductive capacity, and the peak season for pests is the high temperature season in summer. They like hot and humid environments and often attach themselves to leaves. In the process of crawling, they destroy the tender green leaves of the axe-leaf peperomia and produce patches of gray lesions.
