Product Introduction
Dimethomorph Powder is a finished agrochemical fungicide for field crop disease management, categorized as Class 1 agrochemical, Class 2 fungicide. Different from dimethomorph technical raw material for formulation factories or liquid pesticide formulations, this powder disperses in water to prepare spray liquor. It targets oomycete pathogens including Phytophthora and Plasmopara, disrupting cell wall biosynthesis during pathogen growth and spore formation. It delivers protective and early curative control against downy mildew and late blight on grapes, vegetables and potatoes, offering a solid-form fungicide choice for regional distributors and diversified farm operation demands.

Health Benefits & Values
Interfere with Oomycete Cell Wall Biosynthesis and Assembly
Interferes with cell wall biosynthesis and assembly, causing aberrant wall deposition and cell lysis, restraining mycelial spread and sporangia generation.
Combine Preventive and Early Curative Activity
Forms protective barrier on leaf surfaces and suppresses early infection lesions to stop disease expansion.
Target Oomycete-Caused Plant Diseases
Exerts high bioactivity against downy mildew and late blight caused by Phytophthora and Plasmopara. Note: Not effective against Pythium spp.
Suspension Stability for Uniform Coverage
Uniform dispersion after agitation, no rapid sedimentation, ensuring consistent spray coverage.
Tank-Mix Compatibility
Dimethomorph Powder compatible with a range of fungicides, enabling flexible mixing for integrated spray programs.
Core Value for End Users & Distributors
Solid Powder Form Reduces Packaging & Storage Pressure
Dry powder format optimizes packaging weight and volume, lowering warehouse occupancy and logistics burden.
Stable Solid Matrix For Long Inventory Cycles
Dry powder state slows chemical degradation, supporting longer shelf life and flexible stock arrangement for distributors.
Adjustable Dosing Fits Variable Farm Plots
Powder form allows flexible weighing for greenhouses, orchards and scattered small planting areas.
Lower Transport Leakage Risk Than Liquid Formulations
Solid powder packaging avoids liquid spillage during transit, reducing after-sales complaints for distributors.
Easy Operation For Experienced Growers
Simple water dilution workflow, widely accepted by farmers familiar with solid agrochemical powder products.
End-Application Scenarios
Foliar Spraying For Downy Mildew Prevention (Core Track)
Preventive application on grape, cucumber and melon crops before high humidity triggers disease outbreak.
Early Intervention For Potato & Tomato Late Blight
Spray at the onset of disease symptoms to inhibit Phytophthora spread within crop tissues.
Protected Greenhouse Vegetable Disease Control
Used in high-humidity greenhouse environments to suppress recurring oomycete infection pressure.
Anti-Resistance Rotation Spraying Programmes
Alternate use with fungicides of different action sites to slow pathogen resistance development.
Orchard Seasonal Disease Management
Applied in rainy seasons for fruit trees to control oomycete foliar diseases and reduce infection risk.
Application Advantages and Market Positioning
Unique Mode of Action Against Oomycetes
Targets cell wall formation, offering a differentiated tool for downy mildew and late blight control.
Solid Powder Form Provides Differentiated Supply Option
Distinct from liquid pesticide variants, Dimethomorph Powder is suitable for customers who prefer solid dosage forms for field application.
Excellent Rainfastness Suitable For Humid Regions
Strong leaf adhesion reduces agent loss caused by light rain, ideal for rainy and high humidity planting zones.
Reliable Tool For Integrated Disease Resistance Management
No cross-resistance with many conventional fungicides, perfect for rotation and tank-mix anti-resistance strategies.
FAQ (Technical Q&A)
Q1: What is the key difference between it and Dimethomorph WP?
A: It is a general powder formulation, while WP (Wettable Powder) has standardized specifications for wetting time, suspensibility, and moisture content. WP typically provides more consistent suspension stability after water dilution. Powder formulations may be more suitable for certain mixing operations where standard WP specifications are not required.
Q2: How should this powder be prepared for spraying?
A: Add powder into a small amount of water and stir to form a uniform slurry first, then fill up with the remaining water. Maintain agitation during spraying to keep the suspension stable and prevent rapid sedimentation.
Q3: What is the main storage risk for this powder formulation?
A: Moisture absorption is the main risk. Keep packages tightly sealed in a dry warehouse. Severe caking will affect dispersion performance and field efficacy.
Q4: Does Dimethomorph have systemic translocation inside crops?
A: It has translaminar activity and local systemic activity. It moves within leaf tissues and can penetrate from the upper surface to the lower surface, but does not translocate from one leaf to another or from roots to leaves-.
Q5: Can this product be used for soil drench to control root oomycete diseases?
A: Its core advantage is foliar spray. Root drench is not the recommended application method. Additionally, Dimethomorph is not effective against Pythium spp., so it should not be relied upon for Pythium-related root diseases-.
Q6: Why should it be used in rotation with other fungicides?
A: Pathogens may develop resistance if Dimethomorph is used alone continuously. Rotation with fungicides of different action sites, such as multi-site contact fungicides, can effectively delay resistance.
Q7: Can it be mixed with copper-based fungicides?
A: Avoid mixing with strong alkaline pesticides. For copper preparations, carry out a small-scale compatibility test before large-volume tank mixing to check for precipitation.
Q8: What environmental conditions are suitable for spraying?
A: Spray in early morning or late afternoon, avoiding high temperature and strong sunlight at noon. Do not spray if heavy rain is expected within 4 hours. The product has good rainfastness after the spray dries.
Q9: What is the recommended dosage for foliar application?
A: For cucumber downy mildew control, use 30–40 g of product per mu with conventional water volume. For potato late blight, follow local label recommendations. Always calibrate spray equipment before application.
Q10: What is the key difference between this finished powder and Dimethomorph Technical?
A: Dimethomorph Technical is a raw material for pesticide manufacturers to produce finished formulations. This Dimethomorph Powder is a ready-to-use finished product. Users only need to dilute with water before field spraying, without secondary processing.
