What crops are best for Metalaxyl?

Metalaxyl is particularly effective on crops that are susceptible to oomycete pathogens, such as Phytophthora and downy mildew. Here are some key crops where Metalaxyl provides strong disease control:

1. Potatoes

• Target Diseases: Late blight (Phytophthora infestans), seedling diseases.
• Application: Metalaxyl is commonly applied as a seed treatment or soil treatment at planting and as a foliar spray during the growing season.

2. Grapes

• Target Diseases: Downy mildew (Plasmopara viticola).
• Application: Foliar applications are effective in protecting grape leaves, clusters, and shoots from mildew.

3. Tobacco

• Target Diseases: Black shank (Phytophthora nicotianae), damping-off.
• Application: Metalaxyl is used as a soil drench or seedling treatment to protect young plants.

4. Vegetables (e.g., Cucumbers, Onions)

• Target Diseases: Downy mildew, damping-off.
• Application: Often used as a soil or seed treatment and foliar spray in cucumbers, onions, and other vegetables to manage root and foliar diseases.

5. Soybeans

• Target Diseases: Root rot (Phytophthora sojae).
• Application: Metalaxyl can be applied as a seed treatment to protect against root rot, especially in fields with a history of Phytophthora.

6. Cotton

• Target Diseases: Damping-off, seedling diseases.
• Application: Typically used as a seed treatment to protect young plants from early-season soil-borne diseases.

7. Sugar Beets

• Target Diseases: Pythium root rot, downy mildew.
• Application: Metalaxyl helps protect sugar beet seedlings from soil-borne pathogens.

8. Peanuts

• Target Diseases: Pythium and Phytophthora root rots.
• Application: Applied as a seed treatment or soil drench to manage root rot diseases.

Summary of Metalaxyl-Effective Crops and Diseases

Metalaxyl’s systemic properties make it particularly valuable for crops that experience persistent soil-borne diseases or foliar infections during growth, providing effective long-lasting protection throughout the plant.
