Default Is this Sun Scold or something else?

I have had about a half a dozen green tomatoes get this on about the same place as this Prudens Purple. Is this Sun Scold or something else. Is the tomato eatable?

Yes it is and yes, just cut off the scald.

Hi Dark Rumor I call it sun blister- sun scold. I had 10 or 12 from last week as we had 3 days of 100+ temps. Today I made a pot of Chile I just cut away the bad spots diced them up and put them in

Some varieties will sit and stare at the sun all day and not get scald.
Others need shade and will scald at the slightest hint of direct sun.
Prudens Purple seems to be the latter of the two types.
This is but one of many things to consider when choosing tomatoes to grow in Texas.

This tomato was covered with a piece of green frost cloth like this one in the picture well before it got sun scald. I had several others that were covered with a green cloth get sun scald. I use the green cloth to hide the tomatoes from the mocking birds.

Of the varieties that I grow every year the worst one to get sun scald is Red Barn. Whenever a large fruit doesn't have adequate leaf cover this time of the year on RB it usually gets scalded. Even though I do single stem lean and lower I rarely have many fruits get scalded and we just had two weeks with 100 plus days in a row and only had one badly scalded fruit. I use the Missouri pruning method on most of my plants to give them more coverage but it doesn't always work out. Sometimes when diseases or pests cause the lose of a lot of leaves it is a terrible problem down here.

A couple of years ago during a particularly bad infestation of spider mites I used DE, soapy water and Permethrin to help control them. I lost a lot of leaves and used a really heavy dose of DE in the mix and it left all my fruit with a nice ghostly white coating which seemed to help a great deal with sun scald which should have been bad with all the leaves missing from the spider mite damage. I haven't tried using the coating since but if I do loose a lot of leaves again from any of the many maladies that can hit a tomato patch I am going to try it and see if it really works to protect the fruits from scald. Of course I will leave out the Permethrin unless I am dealing with spider mites again.

I had not considered socks, guess I will hold onto my old socks which should hide the tomatoes from birds and squirrels. Course using TTF the tomatoes are getting to big to put socks on them,

Kaolin clay is supposed to protect the fruit from sun scald and stink bug damage. Doesn’t kill the bugs just prevents them from stinging fruit.
