Disease in Coffee Plant (forum)

Wendy starts with ...
I have a coffee plant but there is something on the leaves and stems - white, furry appearance in 'lumps'

Leaves are drying on ends.

It is grown in a pot in a window position but not in direct sunlight or draft.

Any suggestions on how to make into a healthier plant?

Regards
Wendy

Hi wendy

Do you have a picture of the problem?

It could be an insect of some sort but its hard to tell without a picture.

Hi Wendy
I wonder if this is a similar thing to what I've got on my coffee seedlings? There are brown spots on the leaves and something that looks sort of like cobweb.. I 'll put some photos up soon. I've come across the description of a coffee disease which sounds similar, but no success with treatments, apart from "use an appropriate fungicidal". The disease is called "Rhizoctonia" or "Root-Rot".

The white, furry "lumps" might be mealybugs which I got on my coffee plants. One or more sprays of pyrethrum seemed to do the trick. As for the drying leaves I think I might have the same problem haha. The first pic is mealybugs while the others are my plants.

Hey Nick
I found two of the leaves were stuck together & when I pulled them apart there was this cobweb-like stuff on them, and that yellowy thing on the leaf bottom looks like the larvae for some bug - it wasn't very happy about being disturbed. Are yours similar?

I haven't seen it on my coffee plants yet but I've seen that kind of webbing and spider on nearly all my other fruit trees so it must be pretty common.

Hey Nick,
turns out in my case they're leaf-miner caterpillars, which can apparently be fixed with a spray of white oil. Will see how they go.

Id love to know what kind of soil you have it growing in and do you use any manures or fertilizers on it?As for the photo of furry white its looks like fungal spores of some type.That browning on tips could be,waterlogging or salt burns from water or fertilizer/manure use.If its in potting mix it better have enough fine sand to speed up drying out/give it the free draining property it needs.Soggy soils for subtropicals= bad news.

I also have strange white cocoon like things on my plant. Can I just cut them off? It is an indoor plant so I am limited on the treatment options.

It looks to me like Aphid - Woolly Aphid as well as mite webs etc do they jump when touched? take outside on a cloudy day and white oil / Eco oil type spray -- let drip and bring in -- in next day or 2 wash down with a hose spray not to hard -- this basically happens as they are indoors and no airflow.

lilorfn, those are definitely mealy bugs. If you don't have too many, you can just dab them with methylated spirits on a cotton bud.

They are hard to get rid of if you let them spread.

I had scale insects on once of my indoor coffee trees. You can squirt them off with the jet from your hose that usually works pretty well.

Also if you find a praying mantis put him on the tree, he'll find a good home for them...
