Nasty looking fungus

ovidium · 05-01-2009, 07:15 PM

Hi everybody , my name is Ovidiu and I'm writing from Ireland
A fella I've met on a different forum is screaming for some help due to a weird looking thing that started growing on his chinese elm a couple of weeks ago.
He claims the swealings(as seen in the pics) have a easy detacheble membrane on the outside and some sort of white-ish granules inside. The tree lost many of the leaves and the rest of them seem to have some sort of white dots on the front and white powder on the opposite side.(see pics) He already used a fungicide but with no succes.
He doesn't speak english so I thought I might be able to translate back and forward if anyone can help.
Thanx and hope we'll be able to do somethng about this guy and his little tree.

Looks like red scale treat as you would brown scale. Pup

Hi,

I agree with Pup. However, your friend might want to start with neem oil and work his way up to the more powerful solutions. It is always best to use the least toxic solution. I've had great success in the past with Neem oil and scales. You mix a solution of water, Neem oil and a liquid Dish water detergent such as *Dawn. The detergent goes in last so you don't have it foaming up. This is a great treatment plan for spider mites too.

*I forgot that you are in the UK. By this type of detergant I'm referring to a clear solution even though it is dyed a color, not a creamy solution that will moisturize your hands while you do the dishes. Also I might add...you may have to remove some larger scales by hand. This may be accomplished very carefully with the flat end of a toothpick or something similar.

Hope this helps,

Pup's right, it's scale, and further to what Cheryl said (all good stuff), I would advise your friend to avoid using any systemic insecticides on the tree. As Cheryl said, it's best to use the least toxic, but if you have to get more vigorous, aviod systemics. Chinese elm don't like systemics and tend to respond badly.

The guy's got his sleeves up and elbow greese all over...
He also mentioned that the tree is about 20 years old (big enough) and is got that scale all over including on small and thin branches.
I guess he's saying that's not going to be easy to physically remove everything.
His name is Dara and he's thanking uz guyz!

Scale can be a stubborn problem, because the individual insects blend into the bark so easily.

Also, an adult scale's carapace is impervious to many insecticides, which is why I use a horticultural oil: spray it on and it smothers the little sassenachs. It's the same basic thing as "dormant oil," but lighter weight so it can be used when a plant is in active growth. Since brand names differ between Europe and the US, I won't suggest one; your friend should go to a garden center and explain what he's after.

I also use systemics for scale, but I've never tried them on Chinese elm; best to follow the advice above and leave them alone in this instance.

Do I assume correctly that your friend, and his tree, are also in Ireland?

Hi treebeard55,
The guy actually lives in Romania and I'm sure he'll be able to find the oil u're talking about in his nearest garden centre. He also said that he's going for the neem oil.
Thanking uz guyz for support.
I'll let uz know what happened.

Ovidium,

I hope he is able to find it at the garden center, if not, have him google it and he can order it on-line. This is how I found mine. The Neem oil is derived from the Neem tree's fruits and seeds which are pressed into the oil. The Neem is indigenous to India.

Most importantly, it is easiest to put the solution into a plant mister (with the detergent last) and apply it in that manner. I only use a few drops of the detergent to a mix of the mixture.

I just put my tree into a sink and spray it down from the top to the top of the soil and leave it there to dry out. Wait about 3 days and see how the application has done. If there are some still alive repeat the process. I wouldn't put the tree in the sun until they are gone. After that, a gradual reintroduction to the sun is in order for a few days while it recovers.
