Utricularia longifolia

Maxsea works! Spray lightly on leaves, monthly. :)
Springtails and small isopods, daphnia are also good food source for them.
You can also add peat moss to your substrate, it's usually rich in tiny micro-organisms that will feed your smaller Utricularia.

I never thought of Springtails for feeding them! Mine is in live sphagnum so they should be able to get down to the traps easily.

From my understanding some Utricularia (as well as most plants) will only bloom if you can mimic seasonal cues under artificial conditions e.g., duration of photoperiod, dry vs wet season, and temperatures. As Carson mentioned, having a dry spell may help induce the plant to flower. I'd look up to see what worked for other people in the past and try adjusting it to work in your conditions.

Time and neglect.

It took me 3 years untill my longifolia bloomed. But when it did, it was worth the wait!

I had a full 1020 tray of the stuff, and after I forgot to water it, it sent up 3 spikes! So, I wonder if a dry spell can instigate blooming?

I forgot to water my U.alpina and U.alpina Henry Pittier, and both just sent up spikes, so dry spell might definitely be an option?
 
I am fairly certain my longifolia had a bad case of mildew: slight white spots and purple in other places.

what can I spray it with to get rid of it ?( I know utrics are primadonnas with respect to chemicals )
Paysan 20, sulfur, copper?
 
Are there any healthy parts? Best to take those and start over. Lots of air flow and grow space. Mild room temperature.
Even with treatment, heavily infested parts will die.
 
i have already chopped to the ground all infested.
It grew back the same way.

the dry parts might be from overheating: they cooked for a few days this summer (MAX 37deg )

It's hard to tell from the picture but it doesn't look too bad. Not like the powdery mildew I see on outside plants. Maybe try it out in the room with bright light. Maybe an antifungal.

Which antifungal is safe and efficient? That was my initial question :)

i listed a few I have access to.
 
Never used Paysan. Maybe try brushing some on a small portion of stolon and watching for a day.
Keep it out in the room to increase air flow.
 
if your temps are 37 c thats hot and if the humidity is low that could be leaf burn , if you can cool your grow area and may be shade the plant a bit more it could help , it didn't look like fungal or mold to me more like burn marks , just try a les sunny spot for now see if you get a change ,it may be a process of elimination as is the case with many plants

I can imagine they scorched.
Humidity is high: 70-80%
those temps were max. On average they vary 20-30

Copper salts have been registered by the PMRA as herbicides, so I’d be careful how much you use if you choose this route.

I decided not to use copper cause I read that certain carnivorous plants are sensitive to it.
I used sulphur and it seems it might have caused a few leafs to wilt (they were badly damaged by the mould to start with)

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.
