Do you think these were really pesticide free and home grown?

I finally found, or was told about, a farmers’ market fourteen miles from here. The tomatoes were not only a buck a piece they were also fat and quite round with no signs of insects attempting to enter. Just about picture perfect. They were very good but I think I won’t buy from him next time since I expect homegrown tomatoes to be less round and pristine. Am I correct he sprayed or dusted his tomatoes and therefore should be avoided?
