Product Introduction
70% Hymexazol SP is a high-content soluble powder biocide finished formulation for agricultural soil disease control. Distinct from hymexazol technical raw material for factory compounding or aqueous solution liquid preparations, this powder formulation dissolves rapidly in water to form clear working solution. It inhibits soil-borne pathogenic fungi including Fusarium and Pythium, disrupting pathogen respiratory metabolism and stopping infection progress. Tailored for growers and distributors preferring solid dosage forms, it offers flexible weighing and long shelf stability for soil disinfection and seedling disease protection across diverse planting scenarios.

Health Benefits & Values
Block Pathogen Respiratory Metabolism
Suppresses key enzyme activity of soil fungi to halt spore germination and pathogen proliferation in rhizosphere.
Robust Root Zone Protection for Seedling Stage
Penetrates soil matrix quickly to build protective zone around crop roots and reduce damping-off and root rot risk.
Adaptable to Seed Treatment Operations
Dissolved solution adheres evenly on seed surface to eliminate seed-carried fungal pathogens before sowing.
Stable Bioactivity Across Wide Soil pH Range
Maintain reliable control effect in weakly acidic to neutral soil environments common in farmland.
Flexible Tank-Mix With Water-Soluble Fertilizers
Compatible with most neutral or acidic water-soluble nutrients for combined seedling care and disease prevention.
Core Value for End Users & Distributors
Compact Solid Form Saves Warehouse Space
Powder form delivers higher active ingredient density per unit volume versus AS liquid, cutting storage footprint.
Customizable Weighing for Variable Plot Sizes
Dry powder supports flexible partial dosing, 70% Hymexazol SP suitable for small plots, nursery beds and intermittent application schedules.
Extended Shelf Life With Low Degradation Risk
Solid matrix reduces active ingredient hydrolysis risk, supporting longer inventory cycles for distributors.
Convenient Packaging Handling for Cross-Regional Logistics
Lightweight powder packaging reduces transportation weight compared with liquid formulations, lowering freight cost.
Simple Dissolution Protocol for Field Operation
Fast wetting and dissolving feature enables quick preparation of spray or drench solution with standard stirring.
End-Application Scenarios
Nursery Bed Soil Disinfection (Core Track)
Dissolve and spray on seedling substrate before sowing to reduce soil pathogen base and secure seedling survival rate.
Seed Soaking & Seed Coating Pre-Treatment
Prepare aqueous dilution for seed soaking to remove surface-borne fungi and improve germination health.
Root Drench For Root Rot Remediation
Targeted root zone application for early-stage root rot intervention in vegetables, melons and cash crops.
Small Plot & Orchard Disease Prevention
Fit for scattered orchard and family farm usage where adjustable small-volume dosing is required.
Soil Pre-Plant Disinfection for Rotational Crops
Soil treatment before planting grain and commercial crops to relieve continuous cropping soil-borne disease pressure.
Application Advantages and Market Positioning
Solid Form Differentiation From Hymexazol AS Series
70% SP meets market demand for users who prefer powder formulations instead of liquid products, enriching product portfolio.
High Loading Soluble Powder For Soil Fungal Control
70% Hymexazol SP high active content balances dosage convenience and storage stability, standing out from low-concentration solid formulations.
Wide Applicability for Seed & Seedling Protection
Strong performance on seed treatment and seedling bed disinfection creates unique selling points for nursery market channels.
Reliable Stability For Long-Distance Distribution
Less risk of leakage during transport compared with liquid formulations, reducing after-sale complaints for distributors.
FAQ (Technical Q&A)
Q1: What are the key advantages of SP over AS liquid formulations for distributors?
A: The SP solid form offers higher active ingredient density per unit volume, reducing storage footprint and transportation weight compared to AS liquids. It also eliminates leakage risk during transport and has longer shelf life due to lower hydrolysis risk in the solid matrix.
Q2: How should it be dissolved properly in the field?
A: Add powder slowly into water under continuous stirring to prevent agglomeration. Use clean neutral water and avoid pouring large quantities at once. The wetting time is ≤60 seconds, and the dissolution degree is ≥99%.
Q3: What is the main risk during storage and how to prevent it?
A: Moisture absorption is the main risk. Keep packages tightly sealed in a dry warehouse. Slight caking from minor moisture can be broken and dissolved, but severe moisture hardening will reduce solubility and bioactivity.
Q4: Can 70% SP be used for seed soaking treatment?
A: Yes. Prepare the aqueous dilution according to label instructions and soak seeds to kill seed-borne pathogens, reduce seed rot, and improve germination rate. This is a preferred application for SP formulations.
Q5: Is there any pipeline blockage risk when used in drip irrigation?
A: The fully dissolved working liquid has no solid residue. Complete dissolution and filtration before injection into drip systems is recommended to avoid blockage. Flush the system with clean water after application.
Q6: What are the differences in application timing between SP and AS formulations?
A: SP requires a dissolution step before application, making it suitable for pre-planned operations such as seed soaking and nursery bed disinfection. AS is ready-to-use and better suited for large-scale fertigation where rapid preparation is needed.
Q7: Which soil types are most suitable for 70% SP application?
A: It performs well in most neutral and weakly acidic soils. Heavy alkaline soil will weaken efficacy. Soil pH adjustment is suggested before application in alkaline conditions.
Q8: How does the dissolution degree affect field efficacy?
A: The specification requires a dissolution degree of ≥99%. Insufficient dissolution may leave particles that clog spray nozzles and reduce uniform coverage. Proper stirring and adequate water volume are essential.
Q9: What is the recommended dosage for soil drench application?
A: For pre-planting soil treatment, incorporate 2–3 kg/ha of 70% SP formulation into the topsoil-. For soil drench, apply 30–60 g/hl. Always follow the specific crop label.
Q10: Can 70% Hymexazol SP be tank-mixed with water-soluble fertilizers?
A: Yes. It is compatible with most neutral and acidic water-soluble fertilizers. Avoid mixing with strongly alkaline fertilizers. A small-scale jar test is recommended before large-area application.
