Search for Dyna-Gro Neem Oil. It's 100% neem. You will still dilute it to apply to the plants.

Thank you so much.

The effectiveness of any horticultural oil in treating scale insect pests has very little to do with the concentration of the oil but everything to do with the type of scale and the timing of the applications. Soft scale can be treated at pretty much any time but armored scale is only well controlled with oil when it is applied at the proper period in the life cycle of the insect. Your photos do not show the scale problem clearly enough for me for me to determine which type you might be dealing with so you might have to do some research on your own. Or post more detailed photos.

The benefit of using neem is that it is a safe, plant based oil suited for use indoors at any time of year. And it also has systemic effects if used as a soil drench. But a systemic takes time to translocate throughout the plant tissues and become effective so often too much time goes by and too damage has been sustained before the systemic action is effective. It can help a lot if you are able to pick off or wipe off the adult scale to the best of your ability as well.

Mind with neem oil that you do keep it away from cats--reactions are unusual, but do happen even with minor exposure. Dogs seem to handle it fine. I'd also recommend keeping young children away from it as you would any other chemical, of course.

Untrue, even that's disputed at best as it doesn't work; I found this in five seconds. I'd look up the toxicity on PubMed as I've seen it, but one would need a login (ETA: Copying text would be cheating them, which I won't do /ETA). I'm sure it's available on the main Web as I've seen the data, so you can spend the time yourself.

Oh, here's an OSU extension if you want, with non-sciency phrasing and free so I don't have to cheat PubMed. As I noted, reactions are rare. Don't feed pesticides to your cat, their livers just aren't up to it.

ETA: Please note that this page also includes information as to neem oil as an abortifacient in rats--so perhaps let's not use it when human and in the first trimester. I'll be using this in the future as it's quite well-phrased. /ETA

where are you.. and can it be taken outside for treatment??

dont be surprised if proper dilution of the 100% product.. takes you right back to the 9% you claim isnt good enough ... more is not better when using any remedy ... and you surely dont want to harm more leaves by slathering anything on too thickly ...

does your plant get enough light.. the leaves and internodal spaces [guessing at that term] ... do not look right ... it might be etoliated ... lacking proper light ... which might be a reason for leaf loss.. beyond the bug issue ...

hot spit.. i may have gotten it right.. lol .... https://duckduckgo.com/?q=internodal+plant&t=ffcm&ia=web

it would also not be all that uncommon for there to be some leaf fall in fall ... older leaves ... its cyclical and normal.. to a certain extent ...

my point being.. there may be others things needed to bring you plant back to full health ...

I just pulled them all out of the pot to exam the roots and saw a ton of dark brown nodes all over the base below the dirt. I have since went and brushed off all that I saw in the shower and have them sitting in water to hopefully drown whatever I missed while I run to the store to buy all new soil and then once I repot them in new soil I’m going to bag my Ming up in a clear bag to hopefully suffocate them as I found that worked when I took clipping from the plant to propagate in fear it would die and all the clips have since lost their bumps and have seen no new bumps merger. Normally I would throw the plant out but as this is my best friends plant that ha had for 6 years that he loved that was killed last December, I refuse to let this die as this plant was his baby.

I will take more pics of the plant and post.

As for light the plant has great light most of the year with a south east bright morning light that is indirect. But as it’s winter I have grow lights set up to offset the lack of light during this months on a timer that starts at 8 am and shuts off at 5 pm.

I live in NYC and can’t take it outside.

I have since moved all my house plants to my bedroom as it is the farthest away from my living room to separate them from this Ming.

I keep reading about so many different ways to kill the scales, most arguing against the other ways what’s best. And I don’t want to try and fail trying out different ways to kill them.

Pics coming soon.

As for Ken

No this are not nodes as this have increased over the past 2 weeks extremely fast. And I am so anal about looking over the Ming I now when something is new.

At first I thought these bumps were normal as they seems to be perfectly aligned. But as I saw the bumps increase in numbers and the once fully branched plant having leaves yellow and falling off in chunks tells me these aren’t normal.

I’m use to this plant shedding a few leaves when winter hits but this isnt a simple shedding but a loss of 95-97% of its leaves now.

The first pic is of it a few months ago. Rest are the clippings I have propagated.

None of your photos show any clear views of these possible pests. Unless they can be accurately identified, then it will be impossible to advise how best to treat.

fwiw, "dark brown nodes all over the base below the dirt" does not sound like scale. To my knowledge, scale insects are not found in the soil or below the soil line. They live and feed off of above ground plant tissue - stems and leaves and leaf petioles - not on the plant roots.

This is why we need photos. Your problem could be something else entirely and therefore require an entirely different method of control.

I love your little propagation jar! Very clever. I might just have to copy this idea.
