What Is Iprodione and Why Is It an Effective Fungicide for Multiple Crops?

Technical Introduction

Iprodione is a contact and systemic dicarboximide fungicide belonging to FRAC Group 2. It is widely used to control a variety of foliar and soil-borne fungal diseases in fruits, vegetables, ornamentals, and cereals.

Its mode of action is through inhibition of fungal spore germination and mycelial growth by interfering with signal transduction and cell division in fungi. Iprodione is particularly effective against Botrytis spp., Sclerotinia spp., and Alternaria spp., making it a key fungicide for managing gray mold, leaf spots, and blights.

Applications

• Vegetables (Tomatoes, Cucurbits, Onions, Peppers):

  • Controls Botrytis gray mold, Alternaria leaf spots, and damping-off diseases.

• Fruits (Strawberries, Grapes, Apples, Peaches):

  • Highly effective against gray mold (Botrytis cinerea) and anthracnose.

• Ornamentals & Nursery Plants:

  • Prevents Botrytis blight and leaf spot diseases in flowers and greenhouse plants.

• Cereals (Wheat, Barley):

  • Manages leaf spots and seedling damping-off caused by soil-borne fungi.

• Seed Treatment:

  • Applied to cereals and vegetables to protect against early-stage fungal infections.

Advantages

• Broad-Spectrum Control: Effective against Botrytis, Sclerotinia, Alternaria, and other foliar pathogens.

• Protective & Curative Action: Inhibits spore germination and suppresses early fungal growth.

• Foliar and Soil Activity: Works on leaves, stems, flowers, and soil-borne pathogens.

• Flexible Formulations: Available as wettable powders, granules, and suspension concentrates.

• Good Crop Safety: Well tolerated across a wide range of crops when applied according to label instructions.

• Resistance Management: Can be rotated or mixed with fungicides from other FRAC groups for sustainable disease control.

FAQ

Q1: What is Iprodione mainly used for?
A: It is used to control Botrytis gray mold, Alternaria leaf spots, Sclerotinia, and other foliar diseases in fruits, vegetables, cereals, and ornamentals.

Q2: Is Iprodione systemic?
A: Iprodione has local systemic activity, moving slightly within plant tissues, but primarily works as a contact fungicide.

Q3: Can Iprodione be used as a seed treatment?
A: Yes, it protects seeds and seedlings against soil-borne fungal pathogens.

Q4: Is resistance a concern with Iprodione?
A: Yes, resistance can develop in Botrytis populations. Rotation with fungicides from other FRAC groups is recommended.

Q5: What crops benefit most from Iprodione?
A: Tomatoes, cucurbits, strawberries, grapes, apples, peaches, cereals, and ornamental flowers.

Q6: Can Iprodione be mixed with other fungicides?
A: Yes, it is often combined with protectant fungicides or systemic fungicides for broader disease management.
