My question is what is it and I've never in my forty years of raising tomatoes have seen this before. The best way to describe it is on green immature tomatoes this mass of black foam-like structure occurs, (which I assume are the egg mass, develop into a tiny brrown beetle like insect and leaves the unrippened tomatoe as if some one took a bite out of it while still attached to the plant. This is a cherokee heirloom variety that I've tried before, but I bought it as a planting this year from Wannamakers in Downers Grove where in the past I'd purchase seed and start my own transplants, and that's why I am stumpped as to what is it and how to eliminate it. (inn forty years of tomatoe propagation I've never witnessed this before.) Thanks for your input, great service!
