Uh oh? Whats this?

Just another opinion for what it's worth, nowadays

I don't grow Vandas, but this type of spotting and streaking doesn't look like any rot or virus I'm familiar with. I agree with those suggesting physical damage and if these were mine I would just wait and see. I am not one to just start spraying stuff unless I am sure I have a target disease or bug. Even then, I am cautious, as my orchids are all indoors.

I agree with Frederico, it looks like mechanical damage (bruising, rubbing, etc.), rather than a fungus or other disease. Vandas can look pretty raggedy after awhile, I guess they bruise because they get so big, and then the leaves last for years and years.
Then they flower, and all is good.

Thanks Dorothy! You are always there when we need you!

it looks like who ever had it gave it a little too much sun, (my vote is sun scorch), which will neither spread nor get worse.
It is very common on Vandas for the owners to try to induce blooming by increasing light exposure

I'm fairly new to orchids (only about 5 years) and only have about 15. I've never had a problem until last week when I found mealybugs on several of my plants. I'm in the process of treating now and I think I have them under control, but I'm wondering what you use listerine, cinnamon and alcohol for. Also, how do you use them? Would one of these products help with the mealybugs?
Thanks,

Minda

Minda,
The listerene and alcohol are for antisceptic purposes, they are basically for cleaning and disinfecting the foliage and exterior of the plant. A clean plant is less likely to have the conditions for bacteria and fungus, although it is still possible. The cinammon is for open wounds, or places where you have cut the plant. Orchids are very succeptible to fungus when they have an open wound. You simply cover the wound with cinammon, and blow away the excess. The cinammon dries the wound, it also has some natural antisceptic qualities, allowing the wound to heal......it's like orchid neosporin combined with a band-aid. I don't think it will deter your pests, though.
