Common Name: Dodemorph Acetate
CAS Number: 2439-10-3
Molecular Formula: C20H41NO3·C2H4O2
Formulation Types: Emulsifiable Concentrate (EC), Wettable Powder (WP)
Mode of Action: Systemic fungicide – inhibits sterol biosynthesis
FRAC Code: 5 (Morpholine group)

🧪 Product Overview:

Dodemorph acetate is a systemic fungicide belonging to the morpholine class, primarily used for the control of powdery mildew and other fungal diseases in a wide range of crops. It functions by inhibiting the biosynthesis of sterols, essential components of fungal cell membranes, thus disrupting fungal development at multiple stages of the lifecycle.

Due to its preventive and curative properties, Dodemorph acetate is especially effective in managing early-stage infections and preventing the spread of disease. It is commonly used in vineyards, vegetable cultivation, and ornamental horticulture.

🌿 Key Features and Benefits:

• ✅ Highly effective against powdery mildew in grapes and other crops

• ✅ Systemic and curative action – absorbs into the plant and halts fungal growth

• ✅ Also provides activity against certain rusts and leaf spot diseases

• ✅ Compatible with other fungicides in resistance management programs

• ✅ Fast action and long residual effect

• ✅ Safe for use in integrated pest management (IPM) programs

🌾 Recommended Crops:

• Grapes (wine and table varieties)

• Vegetables – cucurbits, tomatoes, eggplants

• Ornamentals – roses, chrysanthemum, gerbera

• Other – hops, peppers, and greenhouse crops

🦠 Target Diseases:

• Powdery Mildew (Erysiphe spp., Uncinula necator, Oidium spp.)

• Rusts (Puccinia spp.) – in certain applications

• Leaf spots and minor foliar fungal pathogens

⚙️ Mode of Action:

Dodemorph acetate works as a sterol biosynthesis inhibitor (SBI), specifically affecting the ergosterol formation required for fungal cell membrane integrity. This disrupts:

• Fungal spore germination

• Mycelial development

• Spore production

Being systemic, it is absorbed by the plant and translocated through the vascular system, providing internal protection of new and existing foliage.

📋 Application Guidelines:

• Application Method: Foliar spray with thorough coverage

• Timing: Preventative or at first sign of infection

• Tank Mixing: Compatible with many contact fungicides, including sulfur and copper-based products

⚠️ Safety and Handling:

• Toxicity: Low mammalian toxicity; not classified as carcinogenic or mutagenic

• Protective Equipment: Gloves, long sleeves, goggles during mixing and spraying

• Re-entry Interval (REI): Typically 12–24 hours (check local regulations)

• Pre-harvest Interval (PHI): Grapes – 14 days; other crops – varies

• Environmental Impact: Low risk to bees and beneficial insects when applied properly; avoid application near water bodies

🧬 Resistance Management:

• Belongs to FRAC Group 5

• Rotate with fungicides from different FRAC groups (e.g., triazoles, strobilurins)

• Avoid repeated applications in a single season without alternation

• Supports long-term efficacy in integrated disease control programs

📦 Packaging and Storage:

• Available in 250 ml, 500 ml, 1 L, and 5 L bottles

• Store in a cool, dry, and well-ventilated area away from direct sunlight

• Shelf life: 2–3 years under recommended conditions

✅ Conclusion:

Dodemorph acetate is a trusted and versatile systemic fungicide, particularly valued for its effectiveness against powdery mildew. Its combination of curative and protective properties, low toxicity, and compatibility with IPM strategies make it an ideal solution for growers seeking efficient, long-lasting disease control across various crops.
