I. What to Do When Pilea Peperomioides Gets Pests

During the growth of Pilea peperomioides, for various reasons, the plant will inevitably suffer from pest and disease damage. According to research, the main pests and diseases include: scale insects, red spider mites, leaf spot disease, anthracnose, etc. They all harm the health of the plant. So once discovered, everyone should immediately spray pesticide for control. As for what pesticide to spray, let's continue reading below.

II. Pest and Disease Control for Pilea Peperomioides

1. Scale insects

When it comes to Pilea peperomioides getting pests, it is usually scale insects. Their appearance is caused either by failure to disinfect in time or by the breeding of insect eggs. These insects are small in size and often gather together. They mainly attack the leaves of the plant, affecting the plant's photosynthesis, which leads to yellowing of Pilea peperomioides leaves and detracts from its ornamental value.

Control method: If a small number of scale insects are found, they can be brushed off with a brush and then rinsed clean with water; when there are many scale insects, when there are many scale insects, a 1000-fold dilution of 40% omethoate solution can be used, sprayed once every 8 days, and 2 to 3 consecutive times can effectively control them.

2. Aphids

As a foliage plant, under improper care, Pilea peperomioides can also get aphids. These insects suck the sap from the stems and leaves, causing malnutrition in Pilea peperomioides. Moreover, aphids reproduce quickly. Once you fail to notice them, they will appear in large patches, looking very frightening, so timely control is necessary.

Control method: When there are few aphids, they can be brushed off with a brush dipped in water, and the brushed-off aphids should be promptly gathered and destroyed; when aphids are abundant, spray with a 40.7% emulsifiable concentrate diluted 1 000-2 000 times for control, spraying once every 7-10 days, and 3-4 consecutive times gives excellent results.

3. Red spider mites

When it comes to Pilea peperomioides getting pests, besides scale insects and aphids, red spider mites also commonly appear. When cultivated indoors, if ventilation conditions are poor, Pilea peperomioides often suffers from red spider mite damage. Although these insects are small, they can use their sharp mouthparts to suck nutrients from the leaves, thereby affecting the normal growth of Pilea peperomioides.

Control method: When red spider mites are found, spray with a 1000-fold dilution of dimethoate or a 1000-fold dilution of 20% dicofol emulsifiable concentrate for control, once every 5-7 days, and 2-3 consecutive times can completely eliminate them.

4. Anthracnose

Besides getting pests, Pilea peperomioides can also get diseases, among which the most common is anthracnose. It is generally caused by bacteria and easily occurs in hot and humid summers. This disease causes brown small spots to appear on Pilea peperomioides leaves, which then expand into round or oval shapes, and in severe cases the entire plant is damaged.

Control method: When diseased leaves are found, remove them immediately to reduce the source of disease; in the early stage of the disease, first open windows for ventilation to reduce indoor air humidity, then spray with a 800-1500 fold dilution of 50% thiophanate-methyl wettable powder for treatment, spraying once every 7-10 days, supplemented by a 1% equal-amount Bordeaux mixture, once every half month. After doing this, the disease can basically be cured.

5. Leaf spot disease

When the indoor temperature fluctuates greatly in a short period, or when too much water is given during the dormant period, Pilea peperomioides is also prone to leaf spot disease. Symptoms: Many small brown spots appear on the leaves of Pilea peperomioides, and in severe cases the spots spread across the entire leaf.

Control method: When the above symptoms are found, promptly remove the diseased leaves and destroy them in a centralized manner to reduce the source of disease; then use an 800-fold dilution of chlorothalonil for foliar spraying, once every 7-8 days, for 2-3 consecutive times, and it can basically recover.
