Help to diagnose disease

[Stegefever]

Hi guys​ and gals,
Have joined the forum a while ago and been reading it ever since, can't thank you all enough for sharing your experiences.
But finally have a reason to post something​: one of this year's chillies I'm growing is variety called Basket of Fire, and it was growing steadily all the time with good growth and good leaves. Last week I did notice something unusual on the back of the leaf - see picture http://imgur.com/a/nxDD5 . And I have suspicion it is some sort of disease, as I noticed same formations starting to appear on my Cayenne too.
Please help me to find a solution to this, or at least point in the right direction. Don't want to loose any of my plants.
Thanks in advance.
Tom

Don't panic! All is good. I had a quick look at the image and all I can see is a small amount of oedema.

It is like a sweat rash. The plant is having trouble ridding itself of excess water.

Causes are as follows:

1. Overwatering.
2. Lack of oxygen to the roots.
3. Compacted soil/compost.
4. Lack of airflow over the plants.
5. Excessive relative humidity

To confirm which one. Tip the plant gently out of the pot and inspect the compost and roots. You may find the soil dry on top but sodden toward the bottom.

Consider gently shaking the soil off and re-potting with fresh soil and monitor how much you water.

It won't hurt the plant at this stage, but needs correcting. Hope this helps.

Thanks Heefy, I will follow your advice and report progress. Thanks. :)

Just to report, repotted my Basket of fire, less watering. Result: new leaves seem to be growing without any signs of oedema. Thanks again Heefy

My pleasure. It's very common. I still get it on plants from time to time.

Hello everyone,
I came here because of the exact same thing start showing on my chilli leaves.
Now that I know the problem I have improved my air flow around my plant using a small (80mm) pc fan and gonna leave the plants on the dry side in the future.
My question is: are the already infected? leaves recover or they will just die? The new ones doesn't have the symptom for now.
Thanks everyone

Edit: my case is even less presented then the OP's

They will probably recover as long as they're not too far gone.

And welcome to the forum!

Hi all!

This is my first season trying to grow a couple of chili varieties.
Most look good, but on 3 of my plants I have this "rash" on the back side of many leaves that I don't know what is.
The plants are still producing flowers and chilis, so hopefully not too bad..

I've googled chili diseases but not seen anything looking like mine.
But the picture of the original poster here have some similarities, so I was wondering if anyone could look at my issue and tell me if it is the same?

That is called oedema which is down to over watering and/or bad airflow

[TheNordic]

Thank you!

Hm, I will try to give them a little less water and see if that helps.

Thanks for the swift reply!

[phillyb86]

Try and increase airflow too if you can

[Mitzi]

Phil is correct - it's a classic case of oedema. Dry them out (even to the point where they start to wilt) and either get a fan on them or space them out more.
