| It doesn't look like cymbidium virus to me. It looks more like mechanical damage. Someone did suggest sunburn which is a possibility. If you're concerned, I suggest considering cuttign the leaf off. Don't dispose of it in compost or anywhere it could cpread to other plants just incase it is a fungal infection of some sort. Take Cynthis'a advice about the TSP I used to use it regularly when I lived in the US. You can't get it here in Australia. I think you've probably ot got much to worry about. I don't think virus testing should cost much. When it lived in the US (only about 5 yers ago) I could get it done through my orchid society for $5 per test.
