Karathane Gold Fungicide, by Corteva Agriscience, is a reliable contact fungicide that provides effective control of powdery mildew in various crops.1 It's particularly known for its efficacy even at low temperatures and its ability to control powdery mildew on woody parts of plants.2

Key Features and Benefits:

• Targeted Control: Specifically designed to control powdery mildew (caused by various fungi like Podosphaera spp.3 and Erysiphe spp.) in crops like grapes, mangoes, chili peppers, apples, and roses.

• Contact Action: Works primarily through contact, forming a protective layer on the plant surface and inhibiting spore germination and growth.4

• Eradicative, Protective, and Curative Action: Offers a multi-pronged approach – it eradicates existing powdery mildew colonies, protects against new infections, and has some curative action on early infections.5

• Effective at Low Temperatures: Maintains efficacy even in cooler conditions, unlike some other fungicides that may be less effective in lower temperatures.6

• Control on Woody Parts: Significantly better at controlling powdery mildew on the woody parts of plants, such as stems and branches.7

• Resistance Management Tool: Due to its contact action and unique mode of action, it is recommended for use in rotation with systemic fungicides to prevent resistance development.8

Active Ingredient:

• Meptyldinocap 35.7% EC (Emulsifiable Concentrate)9

Mode of Action:

Karathane Gold works by disrupting energy production in fungal cells.10 It acts as an uncoupler of oxidative phosphorylation, upsetting the electrochemical balance of the fungal cell and preventing the formation of energy-rich ATP.1112 This affects the respiration and cell wall formation in the target fungi, ultimately leading to their control.13
