Pest and disease control of wind orchid

1. Sclerotium rot

This disease usually occurs more frequently after mildew and rain. When the disease first starts to occur, there will be a lot of white silk at the base of its leaves, which will cause its roots and stems to rot directly.

Prevention and control methods: First, we can remove the infected soil and then sprinkle some lime on it. It can have very good effects. If you want to achieve a complete cure at that time, you need to pay attention to ventilation and light transmission at normal times, and make the drainage of the potting soil better. For some seriously diseased plants, they must be burned in time.

2. Anthrax

Generally speaking, this disease occurs almost all year round, and is more severe when the temperature is high and there is a lot of rain. The spots usually extend from the tip of the leaf toward the rhizome. They are brown at first, then slowly expand and many small black spots appear. In severe cases, the entire plant may die.

Prevention and control methods: When the disease first starts to occur, you can spray some medicine, basically once every 7 to 10 days. Then add a little auxiliary solution and spray it once every half a month, spraying 3 to 5 times in succession.

3. Scale insects

It is also a very nasty bug. They reproduce very quickly, especially when the temperature is high and the air circulation is poor. They will directly cause great damage to the leaves of the plant. In severe cases, they can eat almost all the leaves on the entire plant, which will directly affect the growth of the plant and make the appearance look ugly.

Prevention and control methods: If the number is not particularly large, we can just pick it off ourselves, but it must be removed thoroughly to prevent the production of new insect eggs. If the number is large, you should use some special pesticides to spray them, which can also cure the insects.
