What are the diseases and pests of cycads?
For netizens who are concerned, here are some experiences on the maintenance of green plants, detailing the diseases and pests of cycads and the common diseases and pests and their solutions. Let's learn about them together below.
Cycads are plants of the tropical regions and are usually common outdoors. Few people see them cultivated at home because of their large size, which is not suitable for indoor cultivation. However, cycads often suffer from diseases and pests during the summer, and many people may not know what diseases and pests affect cycads. Let's follow the editor to learn about the prevention and control of cycad diseases and pests.
【One: What are the diseases and pests of cycads】
<1. Spot Disease>
This is a common disease of cycads, usually occurring in hot and rainy weather. Once the plant is infected with this disease, it will continue to erode and expand, and then round or irregular shapes will appear on the branches and leaves. The center of the lesions will turn from dark brown to grayish-white, causing the leaves to wither and break.
<2. Scale Insects>
Scale insects are also one of the more harmful pests, especially in the hot summer. Plants are most likely to be infected with this pest. If the scale insects are not treated promptly, the cycad may develop rotting leaves, and in severe cases, the entire plant may die.
<3. Anthracnose>
The disease initially presents as yellow or red spots on the leaf surface, which gradually expand and turn brown or reddish-brown. In severe cases, the entire leaf or even the entire branch may wither. It is necessary to spray pesticides promptly to allow the plant to recover more quickly. Therefore, to prevent the plant from being infected with this disease, it is best to keep it in a well-ventilated position.
<4. Stem Rot Disease>
What diseases and pests do cycads have?
Stem rot disease is also one of the diseases that cause significant harm to plants, characterized by rapid development and rapid spread. If not detected or controlled in time, it can lead to widespread disease, causing significant losses. For diseased plants, the affected part should be removed in the early stages of the disease to effectively limit the spread of stem rot disease.
【Two: Prevention and Control of Cycad Diseases and Pests】
To prevent plants from being infected with diseases and pests, it is necessary to strengthen cultivation management, especially when transplanting plants, to minimize damage to the roots. After planting, water thoroughly to keep the soil moist and set up a shed for shading. During the process of loading and unloading seedlings, avoid damaging the stems, as this can easily lead to the invasion of pathogens.
If the plant is already infected with diseases and pests, it should be treated promptly with pesticides. A 70% carbendazim 500x solution can be used for spraying. For cycad root rot disease, once diseased plants are found, immediately remove the rotting roots and the surrounding soil carrying the pathogen. Soil disinfection can be done with 40% formalin, or a mixture of 70% pentachloronitrobenzene and 80% zineb powder.
<Conclusion>
Through the detailed introduction above, we believe that everyone now knows what diseases and pests affect cycads. Generally speaking, the most common diseases and pests of cycads are four: spot disease, scale insects, anthracnose, and stem rot disease, all of which can cause certain impacts on the plant. Therefore, plant enthusiasts can follow the above methods for the prevention and control of cycad diseases and pests.
