Utricularia longifolia

I did a bit of sleuthing and checked with the plant people at work and I can confirm that it is definitely not powdery mildew. It was suggested that it may not be a mould or fungus, but non-optimal growing conditions. I reassured my contact that carnivorous plant folk are fastidious about growing conditions. So, this has stumped the scientists at my end. Sorry I couldn’t give you a more definite answer.

Thanks a lot. The only think I could imagine could be better is lower the light level (that was initial suspicion).
The problem is that light burn pattern look different on other plants (colour is consistent though).
 
Malathion has worked the best for me for many decades. Powdery Mildew, fungal growth to insane spider mite infestation. All of my plants, tender to real brutes, indoor or, outdoor have responded well with Malathion, this product is amazing. They use to sell Ambush, that got ban but you can still get it at Rona Montreal.

Yuck. Organophosphates.
I am sure not to have mites since I monitor all the time.
I don’t see how malathion can help with fungal infections it being an insecticide ( unless if fungal caused by insects like sooty mold, etc )
 
Powdery mildew is easily treated with a mixture of water/dish detergent/baking soda. This must be done early or the affected parts will die after treatment. Test it on sensitive plants/tissues.

I thought the same way too, until i applied and was surprised by the result.

Hi Lloyd, can you elaborate on this? I believe I have some fungus on one of my plants that i grew from seed. Do you have a rough recipe? Would this be for powder mildew exclusively?
 
Try it on a bit. The soap/baking soda may hurt delicate tissues. Also parts that are heavily affected are probably going to die anyway with that treatment.

I was under impression that baking soda ( and milk ) for mildew was an old wife’s tale ( forgot where I read this )
 
I can't find the initial recipe I used. I just take a tsp each of baking soda and dishsoap in a half liter of water. You can vary it and experiment.

It worked on tomatoes, beebalm and sedum.
 
Baking Soda alters the pH and cellular integrity of the mildew and the soap acts as a surfactant, Lloyd is bang on. It’s not as efficacious as some of the hardcore fungicides available to commercial users, but it’s not bad if you catch the powdery mildew just as it’s beginning. Reapplication number and interval is something you should investigate before using.
