Here is a wonderful link to tomato disease report Iowa Extension done by Iowa State University an extension that has information about tomato diseases. It describes the most common tomato diseases and gives pictures. I have found it to be a wonderful tool to identify my tomato issue we had this year. It does not offer the solution - but it helped me identify the problem. Once I knew what it was, I could research the solution.
Blossom End Rot seems to be our issue this year. (Pictured to the left)
We are not sure if anything can be done for the plants already effected this year. Some local friends just told us they pruned their infected fruit off and their plants seem to be producing uninfected fruit afterward, when they had it. So we are hopeful..but unsure if we will have the same result. We wonder if we should just clear the beds and plant something new fro the end of the season. The causes are so varied it might be tricky to prevent next year, but at least now we are informed! The "short of it", is that blossom rot occurs from a lack of calcium absorption to the plant. Just like calcium absorption into our bodies, it is not simple a calcium supplement that is needed, rather the other factors need to be in place for the proper absorption of that is present to take place. This is the first year we have ever had this issue and it is only in our Roma and Amish Paste varieties. My Tomatilla and yellow pear tomatoes seem unaffected. If anyone has wisdom, solutions or experience to share on this topic, please share it in the comments.
