Leaf tail scorch blight

The cause of scorched tail disease is called scorched tail disease in the national orchid boundary, but the cause is not very clear so far. It is speculated that the bacterial infection may be caused by too much water in the planting material, especially in the orchid plants with root injury or rootless.

At the initial stage of the disease, brown disease spots appeared at the end of the leaves, showing brown dry and withered shape. Then the area around the spot turns dark brown and gradually expands, and then small black spots appear on the spot.

Preventing spraying 70% every 15 days can kill 800 times the liquid, which can effectively prevent the occurrence of the disease.

The treatment of orchid plants suffering from this disease should avoid rain or watering, otherwise the disease will expand. If you unfortunately suffer from the disease, you should remove the diseased part and strengthen the disinfection of the orchid house.
