Product Information

Expanded crop label and reduced plant-backs add flexibility, better fit for growers

Reason® 500 SC fungicide is a broad-spectrum foliar fungicide that provides outstanding control of certain plant diseases of potatoes and other tuberous and corm vegetables, leafy vegetables, brassica vegetables, carrots, cotton, onions and other bulb vegetables, cucurbit crops and fruiting vegetables.

Reason is a locally systemic, foliar fungicide that stops disease development at more stages in the disease life cycle, which takes your disease management program to a new level. The active ingredient provides a fast acting, consistently high level of control against many important diseases. This preventive activity, combined with a strong spore-killing effect, provides more complete disease protection than competing products.

Key Benefits

  • Fast acting — Reason exhibits remarkable activity on key stages within the pathogen life cycle "sites of action" for many important diseases. It acts rapidly against both the direct and indirect germination cycles of the disease, resulting in more consistent and effective disease prevention.
  • Strong anti-sporulant activity — Reason prevents sporulation, effectively stopping pathogens before they can spread to healthy leaf tissue.
  • Protects new growth — Reason has very quick uptake and is locally systemic within leaf tissue. Reason applied to leaf buds stays within the plant and protects the new and expanding leaves.
