What is the problem of my tomato fruit?

Sanjeeva Reddy I think it's Blossom End Rot or Tomato Late Blight Please click on green link and compare with your crop

It is the fungal disease like late blight of tomato ,so we can apply azoxystrobin and difeconazole ( brand sell Amistar top in the market ) ,used 15ml per 15 litre water and than spray,will get better results.
