Q.Sunburn
Deal All,
I live in Southern California and the temperature can reached above 115+ and my Mango fruits and Sweet Bell Peppers got very bad sunburn, besides the flowers drooped as well.
So, could you please help me and advise me what should I do/use. I heard there is a some sort of spray that I can spray on the fruits that works as a UV blocker/protector. Can you please guide me and tell me the name of this compound?

We don't recommend specific products, but I know there actually is a product that can be sprayed on plants as a sunscreen. Search the internet with the keywords "plant sunblock," and you'll see there's a powder that can be mixed with water and sprayed on your plants. I have no idea if this is a better solution than shade cloth or netting, but it does exist. Here's one of our articles on sun scald prevention:
