What are these spots on my ee's, brugmansia, tomatos.

[Michael_Andrew]

I have these spots on my ee's, brugmansia, and tomatoes and cannot find anything about it. The brown/black tiny spots are mostly on the stem divisions of the leaf. They seem to be under the surface. On the brug there are white patches on the stems that appear to be on the surface. Dick saw Spot run. Run Spot run. Run away from my babies!


Brown/black spots/specks on the EE:



White patches on the Brug stems:

Can anyone identify?

Thanks,
Michael

Looks like rust scale a type of fungal infection I'm not expert on that are you watering them to Much? the White patches you mentioned sound like possibly a type of mildew which would also suggest to much water are the leafs a good green or are they a bit light colored they look a touch light in the picture my Brugs are dark green

They appear to be some sort of scale for sure. Perhaps coconut scale, but they are generally larger. They can also be a whitish color. I would check with one of the experts here for a more definitive ID and treatment ideas.

Thanks Scot and Paulo. If anything they are under watered. The leaves have good color. The brown/black spots are just on the stems and leaf divisions. The white patches (are only on the brug) can be scraped off but is like if you took paper and glued it on the stem. Its not powdery nor can be wiped off or come off on your finger. On the brug the leaves will turn yellow and drop.

thanks,
Michael

well id start off mild with the chemicals and go up from there perhaps something for roses they tend to need babying so to speak i use Imunox for just about all fugal infections wash hands after using nasty stuff when ingested unfortunately theirs nothing Green that i can think of to fight this type of infection but as i already said I'm no expert but i do get by with the use of this product carefully applied

[damaclese]

o i just wanted to add one thing if your soil has good microbial activity in it with all the necessary organic and minerals components thees types of infections are rare

Well I picked up some horticultural oil. Its list scale on the label. I recently bought the brug from a nursery and that's when I started noticing problems. I'll try this oil and see what happens.


thanks for the help guys.

I used to use stylet oil on aphids and such for grapes. It was fairly economical and also helped with many other things. With Joe's new AZ41 however, I would be more inclined to use his product now. Stylet oil is not bad, but I have no idea about price comparisons.

Michael,

I'll offer my opinion here, and it's how I would do it with anyone who e-mailed me photos (which happens frequently) for pest identification/diagnosis.

You have two distinct things here: 1) The brown/black tiny spots mostly on the stem divisions of the leaf. They seem to be under the surface; 2) On the brug there are white patches on the stems that appear to be on the surface.

For number 1 above, my first impression is possibly a response to injury such as wind abrasion caused by flying dirt particles. The symptoms could be caused by insect feeding injury I suppose (not scale insects), but I do not really see insect pests represented in the photo significantly. However, I am not very familiar with this plant, so I'm just guessing.

For number 2, I do see the patches and I also see what appears to be scale insect(s). However, the scale is not causing the patches; it is a relatively sedentary parasite and is sap-feeding. The patches appear to me to be wound response, such as due to abrasion injury (i.e., stems rubbing) or perhaps sunburn. The scale population, if that is scale, appears to be small.

Does any of this make sense to you? I am sorry I can't be more help than this.

P.S. I do not suspect a plant pathogen to be invloved with the symptoms.

[Michael_Andrew]

Makes total sense Scot. I'm gonna keep the wife away from the leaf blower and pick up some spf 50 or maybe some shade cloth.

thanks
michael

Just an update FYI. After further investigation I found something was eating the brug leaves. The damage looked mostly like leaf miners but most of the trails were all the way through the leaf. I had noticed leaf damage but thought it was from me moving it outside and back in at night. I only realized it was something eating it when I saw where something had eaten right across one of my nasterium leaves. So I presume something was eating at the stems since there are trails like on the leaves. The white patches are wound response exactly as Scot had mentioned. I never have seen what was eating it but have found evidence also on a Philodendron Selloum. The plants were treated with Horticulture oil and all damage has stopped.
