Hello,
I'm posting out of desperation to save my Avocado plant, painstakingly grown from pit, which has developed some kind of disease that is causing irregular brown splotches to form on it's leaves. They start small, and eventually grow larger, and end up turning the spot into a burnt dead spot.
This happened after I had repotted the plant. The diseased foliage started at the top, and has seemed to work it's way down from there. In an effort to control it (and in wanting to correct some lopsided growth and encourage branching), I had lopped off a good 6 inches or more of the growth from the top that was showing signs of disease. After a few days, the lower leaves began to brown as well.
After repotting, I started watering with an insecticidal soap to attempt to control a fungus gnat problem that had been plaguing the plant for some time. My fungus gnat problem mostly went away (I still find some stragglers here and there), but I decided to stop watering the plant with the soap in fear that it was the soap that caused this problem (how toxic IS that stuff? I was under the impression it was fairly safe). I flushed the plant with a lot of water until I could no longer see any soap draining to be sure.
I've also began to spray the foliage with a solution of chamomile and baking soda hoping that the problem is fungal, and the remaining foliage continues to degrade but it seems to be spreading much slower than the initial outbreak - so I'm unsure at this point if my spray is controlling it, or what.
Here are some pictures taken this morning of the foliage. Hope you can help!

Thanks!
Two explanations for this. First, and most probable, the transplanting caused the plant a huge level of stress, so it is loosing leafs. From personal experiance, I know Avocados hate to be transplanted, and suffer quite a bit. If so, it will eventualy get healthy again. The other explanation is after it was repotted, it was placed in a brighter situation then it was in before. If this is the case, move it back to its original position.
