Pristine Fungicide


Pristine® fungicide is the leading fungicide used in specialty crops for the control of a wide spectrum of diseases as well as increased plant/fruit health.

How Pristine Fungicide Works

Pristine features a combination of the active ingredients, pyraclostrobin (the active ingredient in Headline® fungicide) and boscalid to provide disease control in a variety of crops.

Pristine deprives fungal cells of their energy source and eliminates the availability of chemical building blocks for synthesis of essential cellular components. It also interferes with cell respiration and the production of energy.

Pristine is labeled for use on grapes, berries, stone fruit, pome fruit, tree nuts, carrots as well as onions and other bulb vegetables.

  • In grapes, Pristine provides unmatched control of powdery mildew and activity on Botrytis, Phomopsis cane and leaf spot, downy mildew and black rot.
  • In strawberries, Pristine is highly effective against Botrytis gray mold and powdery mildew.
  • Pristine is an all-season total fungicide tool in stone fruit, controlling everything from blossom blight to shothole to scab and even brown rot on the tree and after harvest.
  • In pome fruit, Pristine extends its excellent control of both summer and storage diseases to apples and pears.
  • Pristine is an easy-handling, one-shot solution for total fungicide control in tree nuts. Diseases controlled by Pristine in tree nuts include blossom blight, anthracnose, shothole and scab.

Application Instructions

Concord and related varieties are sensitive to Pristine, use special care when making applications nearby.

Optimum disease control is achieved when Pristine is applied in a regularly scheduled protective spray program and used in a rotation program with other fungicides. 

Do not use Pristine in greenhouse or transplant production. 

Though other application methods are available, ground applications of Pristine are recommended because they provide more thorough coverage. 

Pristine contains boscalid, be cautious and adhere to label recommendations for water protection when applying.

Always read and follow label directions.
