Miltonias sunset orange pseudobulb

[Lamia189]

Hi there again guys.
As some of you who have helped me know, I have recently received an order from shwerter with two miltonias which had fusarium. I have been pretty paranoid about weird discoloration etc in my orchids since. I also wanted to make sure that a miltonia sunset I got a few weeks ago was not infected xd so I took off the smallest pseudobulb... Soon to really regret it because half of the roots were attached to that thing. I'm guessing it was the oldest pseudobulb but it also was located far beneath the rest, so a part of it was in the media. I tried removing it just to see if there was no ring and it came off pretty easily, then I found that the base was orange. So I took out the plant to find out that majority of the roots were dead. The ones that weren't had the orange color as well. I was surprised to see that because I'm getting two new growths and I think a 3rd onevis forming too, but is also kind of orange. The biggest one is growing very quickly. So I thought the plant was very healthy. I guess I'm lucky because the new shoots with produce new roots, but I have no idea what the orange is... Is that some kind of rot?
I find myself asking alot questions on this forum xD I am still pretty inexperienced so thank you guys for all the help.

I think you need to stop panicking and cutting up healthy plants. You will kill more plants that way than would die of fusarium.

Fusarium is in the environment around us. Almost every growing space in the world has it sitting there, waiting for plants to become unhealthy so it can attack them. You cannot sterilize your growing area and keep it fungus-free. This is completely impossible.

Focus on keeping your plants as healthy as possible, and use good cleanliness and hygiene practices (don't splash water from plant to plant) and you won't have to worry much about fungus diseases.

Many people think treating plants with beneficial microorganisms can help prevent fungal or bacterial infections. I'm not familiar with the research, but products like Inocucor make this claim. I know it's available in the US but I don't know about the EU.

Lamia, I have to agree with estación seca in the previous post. I think you are becoming overly concerned that all of your orchids are infected with Fusarium. The orchids you recently purchased were the ones you had Fusarium concerns over. Was this one of them? If not, the discoloration is unlikely to be Fusarium because it would take a period of time before any discoloration would become evident if it was infected.

The orange bulb & roots may just be discolored from whatever medium they have been growing in. Please let us know: 1. The type of medium being used & how long since the orchid has been repotted; 2. Is the orange pseudobulb firm or soft? If it is firm, it is probably healthy & you should repot it. 3. What fungicides do you have access to?

I think I have watched too many youtube videos where majority of greenhouses were lost to fusarium haha. Since I got a sick orchid from a nursery, I thought there would be a chance to get a sick one from a store as well. I just wanted to be sure, but yes, you are right. Im after getting paranoid.
Now I was just surprised to see orange pseudobulbs and I thought maybe its some weird fungus. The orange pseudobulb is firm. So since everything that is touching the media has gone orange then that would stick. I repotted it this jan/start of feb id say. I am using a seramis mix, it has some clay bits in it and pine bark. I think I just need to relax and leave the orchids grow... Im one of those people who tend to expect the worst
I do not currently have a fungicide. Im just using some cinnamon on cuts etc. I haven't had a good look around the gardening stores yet, but I was thinking of getting hydrogen peroxide 3% instead.
