How to prevent and control wind orchid pests and diseases? Detailed methods

1. Southern blight

This disease generally occurs more often after the plum rain season. When it first appears, there will be a lot of white mycelium at the base of its leaves, which will cause its rhizome to rot directly.

Prevention and control methods: First, we can remove the infected soil, then sprinkle some lime on top. This can have a very good effect. But if you want to achieve a complete cure, then in normal times you need to pay attention to giving it ventilation and light, and make the potting soil drain better. For some severely diseased plants, be sure to burn them promptly.

2. Anthracnose

Generally speaking, this disease is present all year round, and it is even more severe during high temperatures and rainy periods. The lesions generally first extend from the leaf tip toward the rhizome area; at first they are brown, then they gradually expand and many small black spots appear. In severe cases, they can even kill the entire plant.

Prevention and control methods: When it first appears, you can first spray with some medication, basically once every 7 to 10 days. Then add a supplementary solution and spray once every half month, for 3 to 5 consecutive sprays.

3. Scale insects

They are also a very annoying pest. They reproduce very quickly, especially during high temperatures and poor air circulation, when they are even faster. They directly cause great damage to the plant's leaves. In severe cases, they can eat almost all the leaves on the entire plant, which directly affects the plant's growth and also makes its appearance look very unsightly.

Prevention and control methods: If the number is not particularly large, then we can just remove them by hand, but they must be completely cleared to prevent new eggs from being produced. If the number is very large, then some specialized pesticide should be sprayed, which can also eradicate this pest.
