One of my very last liliums that has opened today has a few blotches. The upper leaves don't look great either, although for some reason it never looks as bad in the photos...

Thoughts?

At this stage I'm preparing to eliminate it just as a precaution, especially since I have others that are very similar.

That would have me worried too, Joshua. If it isn't vital to you I'd be rid of it just to be safe.

Agree with Della. If that is from a stem bulblet, then you had better inspect mom, too.

Thanks Della and Rick. Don't think there were any others showing signs, just that one. I'm in the process of poisoning it, as it's in a pot with a number of others and won't be easy to dig out.

Poisoning lilies takes a while, because of the comparatively large biomass of the bulb that will absorb and dilute any contaminants. Meanwhile, stressed plants in general can act like beacons for insects to feast and possibly spread virus if it is infected. If you're doing a poison thing, maybe you ought to overdose it with an insecticide rather than an herbicide (?).

Just thinking out loud here....

Thanks for the thought, Rick. I'm also spraying at the moment for aphids and mites, although haven't seen any on or near this one. The aphids seem to be targeting my probable 'Red Velvet' on the other side of the house - the seed pods are like magnets to them at the moment.

I'm open to suggestions as to what might be the most effective. I've just covered it again with Yates Zero Rapid Gel (https://www.bunnings.com.au/ya...), which seems to have an higher amount of the same ingredient that's found in Roundup.

That Yates product site is a little baffling if you look at the product details........

--- If it is not a post emergent and not a preemergent, what could it be? Rolling on the floor laughing

--- If it is not a selective herbicide, and not a non-selective herbicide, what does it do? Rolling on the floor laughing

Silly people!
It is non-selective and a post emergent.

I often go to the manufacturer site rather than Bunnings for the technical data, as they don't always get it right. The actual packaging says it's non-selective.

Cutting off the stem and dabbing strait roundup (42%) on it with a foam paint applicator should kill it, and removes the top so there is not foliage for insects to feed on and spread disease. Bulbs can be hard to kill early in the season when they are pushing growth, this works much better later in the season. This is the way I thin my seedlings and other thickets of lilies now that selling is such a negative experience, and killing is far more economical.

Thanks for the additional suggestion - I will definitely keep that in mind. It seems my repeated application has worked now, as the stem has completely died off (and everything else in the pot appears okay at the moment). I will monitor the rest of the pot next summer.

FYI, 42% (or 50%) glyphosate Round Up is the heavy duty stuff (and what is recommended to kill buckthorn). The regular concentrate is 18%.
