When I went out to check my tomatoes this morning, I found that half of them have been almost stripped of leaves. Three days ago they were fine. It is not tomato hornworms. I am familiar with them and I checked very carefully. On two of the leaves I found clumps of brown dots about each about 1/16" in diameter. On close examination each of the brown dots look like egg sacs. I went to Lowes and got some spray that is supposed to work, but I would like to know what the culprit is. Ideas anyone? I am in southern Missouri.
