My Tillandsia intermedia is looking even sadder than it was three months ago. Since then, I’ve really controlled the watering and for a while, there were no new yellow patches. However recently, I noticed that some new yellow patches had appeared. Now I know that the patches can’t be due to overwatering so the other possible cause was fungal infection.
Besides the T. intermedia, my Tillandsia paucifolia also looked really sad. The yellow patches spread quickly over a few days to almost the whole plant. Some parts of the leaves had already died off.
Searching online it seemed that the brown (and possibly yellow) parts will remind but using a fungicide could prevent it from spreading and killing the plant.
So I went out and bought a bottle of fungicide from Giant for $6.50. A fellow tillandsia owner recommended Vitaram but this was the only fungicide available at Giant. The nurseries will have more fungicide varieties but getting there is quite inconvenient for me.
By pure luck, captan happens to be one of the fungicide that can be used on tillandsias. Most articles online recommended to use fungicide that can be used on roses, which happens to be one of the plants listed on this bottle. To use this on tillandsias, I need to reduce the dosage by half. The bottle states mixing 3 grams of the fungicide power with 1 litre of water, so it means I should use 1.5 grams per 1 litre of water.
It is also written on the bottle that a measuring spoon is included but I cannot find it. It may be buried too deeply in the powder but I didn’t really feel like digging for it so I just estimate. I wore disposable gloves when mixing it as the bottle says it can be absorbed on contact with skin. Then I dipped the plants in the solution and left them to drip dry on the sink. I didn’t want to spray them. Spraying is messy and I am doing this indoors so I didn’t want the fungicide to get everywhere.
Last week I applied this on my T. intermedia, T. paucifolia and some other plants that were showing brown spots. I just want to make sure that the fungicide didn’t kill off the tillandsia before I apply this to the rest of my collection.
Good news is they are still alive after one week so I dunked the rest of the plants in the fungicide solution, even those that looked healthy. This will be useful for preventing future fungal infection now that the rainy season is starting.
