Product Introduction

Dimethomorph is a highly effective selective systemic fungicide with a specific control spectrum, primarily targeting Oomycete diseases (such as downy mildew, late blight, etc.). Its core mechanism of action is to inhibit the biosynthesis of pathogen cell walls, thereby blocking spore germination and mycelial growth. Due to its unique action site, the risk of pathogen resistance is extremely low, making it suitable for long-term prevention and control.

Product Advantages

• Specifically controls Oomycete diseases, with excellent control efficacy against downy mildew, late blight, etc.

• Low resistance risk: unique action site ensures minimal risk of drug resistance even with long-term use.

• Long residual period (usually 10–14 days), reducing application frequency and lowering costs.

• Strong systemic translocation: can be absorbed through leaves and translocated to all parts of the plant.

• Good formulation compatibility: can be mixed with most non-alkaline pesticides (to be prepared and used immediately).

• High crop safety: no phytotoxicity risk to cucumbers, grapes, potatoes, etc., when used at recommended doses.

Safety Protection, Storage, and Transportation

• Harmful to aquatic organisms; avoid drift of pesticide solution into rivers, lakes and other water bodies.

• Wear protective gloves, masks and protective clothing during application to prevent skin contact and inhalation.

• Store in a well-ventilated, dry and cool place, far from food, feed and areas accessible to children.
