Is Heritage G or Pillar G better for treating gray leaf spot on St Augustine?

I have been ordering Pillar G from you guys for this problem and it worked fine, however, on my last order I accidentally ordered Heritage G. I will use this, but was wondering your opinion for treatment in the future, the Heritage G or Pillar G?

Answer:

The Pillar G Instrinic Granular Fungicide label states that you should not apply more than two sequential strobilurin-based fungicides sequentially prior to rotation to a different mode of action or classification.  Pillar G and Heritage G both have a Group 11 classification so they would not be the best products to rotate to protect against fungicide and plant resistance. A better option would be a Group 1 fungicide like Clearys 3336G Fungicide or a Group 3 fungicide like Eagle 20EW
