all pepper plants have this problem

11 years ago

I have noticed that all my pepper plants are having yellow leaves with brown spots. They are not doing good. We are having too much rain and hot humid climate, is this reason for this or any mineral deficiency? Can anyone identify the problem and provide me info on how to address this issue.

looks like bacterial spot...

Given all the bulls-eye yellow around the brown spots I'd be inclined to label it Early Blight as BS usually doesn't have as much associated yellowing IME. But either way the treatment is the same - strip off all the affected leaves and use a fungicide to prevent spread. In this case I'd recommend one of the copper-based ones as they will help with both diseases while some others are primarily used for only fungus issues.

I think that a bacterial infection is what you are having there...no chemical treatment has been found to be effective but mechanical means might save your plants - stripping off the affected leaves and disposing the litter properly. But it is already inside your plants system - the bacteria. Oh well like others do especially if they are into mass production, they uproot everything, dispose it properly and plant for the next season. Source could be from your seed or it is already in the soil and triggered by the weather condition that you mentioned.

If it is a fungal infection, well you may increase the pH of your soil. Fungus does not love to dwell in basic environments. Try the baking soda solution - 1 tablespoon per liter.

Peppers are really susceptible to pests and diseases...yeah worldwide. It is a matter of having a chelated seed starter to ensure robustness in the field while nurturing it properly.

Good luck. Next time, do keep monitoring for that kind of symptom as it is contagious. If you start spotting one, strip it off right away...

I pulled the plants out as they were not doing any good. Can I use the soil t for other planting or have to trash it? Do you think the soil has bacteria still in it and might infect any plants planted in that soil?

Is this container soil you are talking about "trashing"? I assume so since it would be hard to trash in ground garden soil. :)

Keep in mind that bacteria and fungus normally reside in all soil. They are only an issue for the plants given the right weather conditions so normally most container soils can be re-used with no issues. You can just dump the container out on a plastic tarp or such mix it all up well, mix in some fresh soil mix and fertilizer for nutrients, and refill the container.
