Step 1: Petal Fall
After your developing almonds have bloomed and petals begin to fall, apply Miravis® Prime fungicide to dial up your red leaf blotch defense. This is the most critical timing to help prevent red leaf blotch.

Step 2: Post Petal Fall
Apply Miravis Duo or Quadris Top® fungicide between two to three weeks post petal fall for continued red leaf blotch protection.

Step 3: Follow-Up Spray
For high-risk or vulnerable orchards, a third preventative fungicide application is recommended about five weeks after petal fall.
