How to quickly determine whether the tip-burn of orchid leaves is physiological or pathological
If the tip-burn is pathological, everyone should use medication promptly. Generally, this kind of manifestation on the leaves is caused by fungal infections, so everyone should use fungicides in a timely manner.
People may often notice that orchids have the phenomenon of tip-burn on their leaves. When this happens, many orchid enthusiasts spray fungicides on the orchids to kill the fungus. However, this practice is actually very wrong.
Because the tip-burn of orchids can be either pathological or physiological. If it's pathological, we need to use fungicides for treatment. But if it's physiological, even if you spray a lot of fungicides, it won't be effective. So, how do we determine whether the tip-burn of orchid leaves is physiological or pathological.
1. Determination
First, let's look at the physiological tip-burn. Physiological tip-burn is characterized by the tip area being completely black or brown, and there are no transverse lines on the leaf surface. Moreover, at the junction of the diseased leaf, there are no black transverse lines.
Pathological tip-burn is different. It not only has a brown color but also has some black spots on it. There are many small black spots and there are distinct black transverse lines.
Have you noticed that the color on top is relatively lighter, and the color below is darker? The transverse lines here are dark brown or black, and the bottom is slightly yellowish. This is a pathological tip-burn.
2. Pathological
If the tip-burn is pathological, everyone should use medication promptly. Generally, the infections on the leaves are caused by fungi, so everyone should use fungicides in a timely manner.
3. Physiological
However, the reasons for physiological tip-burn are very diverse, such as insufficient air humidity, lack of water in the potting soil, too strong light, or your root rot, which can prevent the absorption of water and nutrients, leading to tip-burn on the leaves.
So, there are many reasons, and everyone must identify what went wrong in their care and make timely adjustments to effectively prevent the leaves from continuing to burn. Therefore, not all leaf tip-burns require the use of fungicides. Everyone must learn to distinguish between pathological and physiological first, and then we can come up with a solution.
