I. How to deal with bugs on lucky bamboo

Lucky bamboo has strong vitality and generally rarely gets bugs, but under improper care and poor environmental conditions, it can also get bugs and become sick. The main diseases of lucky bamboo are leaf spot, root rot and anthracnose, and the main pests are scale insects and red spider mites. Their appearance will affect the health and appearance of the plant, so once found they should be removed immediately!

II. Pest and disease control for lucky bamboo

1. Lucky bamboo scale insects

Although lucky bamboo is not prone to bugs, in poorly ventilated and poorly lit environments, scale insects will also come calling. These insects generally float and attach to the surface of the plant's leaves, and their secretions pollute the leaves, affecting the plant's photosynthesis, which leads to wilting leaves and induces sooty mold, causing great harm.

Control method: When there are few scale insects, you can use a brush dipped in water to gently brush off the insects, then spray white vinegar for prevention; when there are many scale insects, you can spray 40% omethoate 1000 times dilution for control, spraying once a week, and 2 to 3 consecutive sprays will be effective.

2. Lucky bamboo red spider mites

Besides scale insects, under high temperature and high humidity with poor ventilation, lucky bamboo may also get red spider mites. These pests mainly pierce the leaves of lucky bamboo with their mouthparts to suck the sap, damaging the plant's chlorophyll, causing the leaves of lucky bamboo to turn yellow and even fall off.

Control method: When individual leaves are affected, the infested leaves can be removed; when more leaves are affected, propargite, dimethoate, huachongjing, fenvalerate and other pesticides should be sprayed early for control.

3. Lucky bamboo root rot

Under improper care, lucky bamboo can also become sick, and the most common is root rot. This disease generally appears when there is excessive watering or poor drainage of the potting soil, combined with a dark indoor environment, causing the roots and stems of lucky bamboo to turn black and rot, accompanied by the yellowing of the lucky bamboo stalks.

Control method: After discovering the above symptoms, cut off the rotted parts of the lucky bamboo, apply sulfur powder, then replace with fresh culture soil and replant.

4. Lucky bamboo leaf spot

When the indoor temperature fluctuates greatly in a short period, or when watered too much during the dormant period, lucky bamboo is also prone to leaf spot. This disease mainly harms the lower leaves of lucky bamboo; the diseased leaves will show many small brown spots, and in severe cases the spots will spread over the entire leaf.

Control method: When the above symptoms are found, promptly remove the diseased leaves and destroy them together to reduce the source of infection; in the early stage of the disease, you can also spray 42% kejunqing powder 3000 times dilution on the leaf surface, spraying once every 5-7 days, for 2-3 consecutive sprays, and it can basically recover.

5. Lucky bamboo anthracnose

In the pest and disease control of lucky bamboo, anthracnose is also something everyone needs to prevent. This disease easily occurs in the rainy season when humidity is too high and the environment is not ventilated. If lucky bamboo shows blackened leaf tips and yellow spots on the leaves, it has probably caught anthracnose.

Control method: When the above symptoms are found, if it is winter or spring, promptly remove and destroy the diseased leaves, and sprinkle quicklime to disinfect the soil. In the early stage of the disease, you can spray 75% chlorothalonil 600 times dilution or 50% thiram wettable powder 500 times dilution, spraying once every 7-10 days, and 3 consecutive sprays will be effective.

That's all for the pest and disease control of lucky bamboo. I believe everyone will know what to do when lucky bamboo gets bugs or becomes sick again! Overall, the growing method of lucky bamboo is not difficult; as long as everyone takes good care of it, bugs will not come calling. Finally, may everyone's lucky bamboo grow beautifully~

1. Calathea orbifolia aphids

If you find that Calathea orbifolia has bugs, it is very likely aphids, because they are the main pest of foliage plants. These insects generally appear on tender leaves and newly grown buds, feeding on the sap in the leaves, causing the leaves of Calathea orbifolia to turn yellow, and at the same time black or yellow diseased spots will appear.

Control method: When there are few aphids, manual aphid control can be adopted, using a writing brush or brush to brush off the aphids and bury them in the potting soil; when there are many scale insects, you can spray 40% omethoate 1500 times dilution or 90% trichlorfon solution for control. Usually pay attention to reasonable watering and fertilizing to improve its resistance to pests and diseases.

2. Calathea orbifolia scale insects

When the environment is not ventilated and care is improper, Calathea orbifolia is also prone to scale insects. These insects attach to the leaves, absorbing the nutrients and water within, causing poor growth of Calathea orbifolia, and the leaves chewed by scale insects will also cause other diseases, and in severe cases will directly cause Calathea orbifolia to wither and die.

Control method: When there are few scale insects, you can use a brush for manual treatment; if a large number of scale insects are found, in addition to manual removal, you also need to cooperate with spraying for control. The pesticide can be 50% malathion 1500 times dilution, or 255 imiphos 1000 times dilution for control, spraying once a week, and two consecutive sprays can effectively control it.

3. Calathea orbifolia red spider mites

Besides aphids and scale insects, red spider mites are also a main pest of Calathea orbifolia. These insects often occur when ventilation is poor, mainly piercing the leaves of Calathea orbifolia with their mouthparts to suck the sap, damaging the plant's chlorophyll, causing leaves to turn yellow in mild cases, and even leaf drop in severe cases, seriously affecting the ornamental value.

Control method: After discovering the diseased insects, you can use decis for treatment, or spray 25% fenbutatin oxide EC 800 times dilution, 73% propargite 2000 times dilution and other pesticides.

4. Calathea orbifolia leaf spot

Calathea orbifolia has strong adaptability and can be said to rarely get sick, but under high temperature and poorly ventilated environments, it can also catch leaf spot. In the early stage of the disease, small yellow-brown spots appear on the leaves of Calathea orbifolia, and halos also appear at the edges; in severe cases, the spots will quickly spread to every branch and leaf of Calathea orbifolia, and finally cause Calathea orbifolia to wither and die.

Control method: After discovering the above symptoms, promptly cut off all diseased branches to reduce the source of infection; then spray relevant pesticides, choosing 38% oxadixyl-fosetyl-aluminum 800-1000 times dilution, or 4% flusilazole 1000 times dilution, spraying once every week, and three consecutive sprays will be effective.

5. Calathea orbifolia southern blight

Among the pests and diseases of Calathea orbifolia, southern blight is also something everyone needs to pay attention to. This disease is often more serious in July and August, but it also occurs frequently at ordinary times, often because the soil is too moist and poor. When the disease occurs, it causes purple-brown spots on the leaves, followed by an obvious white mycelium layer, and in severe cases the plant withers and eventually dies.

Control method: After discovering the above symptoms, promptly spray fungicides such as carbendazim, Bordeaux mixture, lime sulfur mixture on the stem base of the plant and on the substrate; or, after the disease occurs, directly remove the infected potting soil and sprinkle pentachloronitrobenzene powder or lime.

That's all for the pest and disease control of Calathea orbifolia. I believe everyone will know what to do when Calathea orbifolia gets bugs or becomes sick again! Overall, the growing method of Calathea orbifolia is not difficult; as long as everyone takes good care of it, bugs will not come calling.
