Seed Soaking
In most cases, a low-concentration (<70 ppm) hypochlorous acid solution is used for seed soaking. However, the specific concentration needs to be adjusted based on the specific crop seed. Farmers are advised to determine this based on their own experience or by consulting relevant research.
For example, research indicates that:
The optimal concentration for soaking watermelon seeds is 80 mg/L;
The optimal concentration for soaking leek seeds is 50 mg/L;
The optimal concentration for soaking cucumber seeds is 100 μg/mL.
Irrigation Water Treatment
After adding hypochlorous acid to irrigation water, the residual chlorine concentration should be controlled at 2–5 ppm.
Combination with Pesticides
The combination ratio of hypochlorous acid with different pesticides varies. For example:
For the control of gray mold in strawberries, using electrolyzed hypochlorous acid water instead of water to dilute thiophanate-methyl and diethofencarb not only achieves the highest control effectiveness (up to 88.25%) but also reduces pesticide usage by 33% to 50%, achieving environmentally friendly control. For pest control, a combination of electrolyzed hypochlorous acid (HOCl) and a 12% biphenyl/clothianidin suspension concentrate (SC) demonstrates excellent control effectiveness against beetles, with an average control rate of 88.9% after 14 days of application.
For more specific mixing ratios and usage protocols, please consult an agricultural expert.
Crop Spraying
Hypochlorous acid (HOCl), an environmentally friendly disinfectant, has gained increasing attention in recent years for its use in crop spraying. Its broad-spectrum bactericidal activity, high efficacy, low toxicity, zero residue, and crop safety make it suitable for the environmentally friendly control of a wide range of crop diseases. The following are key points for its application in crop spraying:
Applicable Concentration
The typical concentration for foliar spraying is 50–100 ppm (available chlorine content), with specific adjustments depending on the crop type, growth stage, and target pathogen.
A small-scale trial is recommended to determine the optimal application concentration to avoid potential foliar allergy reactions caused by high concentrations.
Mechanism of Action
Hypochlorous acid (HCO3) destroys the cell membranes and protein structures of pathogenic microorganisms (such as fungi, bacteria, and viruses), rapidly killing or inhibiting their activity, thereby reducing the spread of diseases.
Application Scenarios
Disease Prevention:
Regular spraying effectively prevents common leaf diseases such as downy mildew, powdery mildew, gray mold, and leaf spot.
Suitable for greenhouses and open-field crops.
Postharvest Treatment:
Spraying fruits or vegetables after harvest can reduce the surface microbial load and extend shelf life.
Combination with Pesticides:
Can be combined with some biopesticides or low-toxic chemical pesticides to enhance synergistic effects and reduce chemical pesticide usage (compatibility must be verified in advance).
Usage instructions
Spraying Frequency: Recommended spraying every 7–10 days, with more frequent spraying during peak disease seasons.
Spraying Time: Apply in the morning, evening, or on cloudy days to avoid direct sunlight that can rapidly decompose hypochlorous acid and reduce the risk of leaf photosensitivity. Equipment Requirements: A standard sprayer will suffice, ensuring uniform atomization and comprehensive coverage.
Precautions
Prepared for immediate use: Prepare or dilute on-site and use immediately to avoid loss of potency.
Avoid mixing with strongly reducing or alkaline substances to prevent chemical reactions that could lead to loss of potency.
Safety: While minimally impacting the human body and the environment, it is recommended to wear protective glasses and a mask during handling to avoid direct contact with eyes and skin.
Storage: Store in a dark, airtight, cool place, avoiding prolonged contact with metal containers.
Real Case Study
In strawberry cultivation, spraying 80 ppm hypochlorous acid solution effectively controls gray mold, achieving over 85% effectiveness.
Spraying leafy vegetables (such as lettuce and spinach) with 50 ppm hypochlorous acid solution significantly reduces the incidence of bacterial soft rot.
Produce Preservation and Postharvest Processing
Hypochlorous acid can also be used for postharvest preservation and processing of agricultural products. Produce is prone to rotting and mold after harvest, which not only affects quality but also leads to significant food waste. Hypochlorous acid, a safe and effective disinfectant, can be used for post-harvest disinfection of agricultural products at certain concentrations. Appropriate immersion or spraying can effectively kill bacteria and fungi on the surface of agricultural products, extending their shelf life and shelf life.
Limitations
Hypochlorous acid water has a short shelf life and requires regular reapplication.
It is also limited in effectiveness against certain stubborn diseases (such as soil-borne diseases) and must be combined with other control measures.
Summary
Hypochlorous acid water, as a green and safe disinfectant, has broad application prospects for foliar spraying of crops, particularly in green food, organic agriculture, and integrated pest management (IPM) systems. It is recommended that spraying plans be scientifically formulated in conjunction with agronomic practices and disease monitoring.

Applications: From greenhouses to fields
Chlory's technology has been successfully applied in various agricultural scenarios:
Greenhouse cultivation: Hypochlorous acid treatment effectively prevents root rot and fungal infections in the irrigation of vegetables such as tomatoes and cucumbers, increasing yields by approximately 15%.
Field crops: The use of hypochlorous acid in the irrigation systems of grain crops such as wheat and rice has significantly reduced disease incidence and reduced pesticide use.
Hydroponic agriculture: Hypochlorous acid eliminates biofilm issues in circulating water systems and improves nutrient solution utilization efficiency.
Soil remediation: Acidic electrolyzed water prevents soil compaction.
We export to countries such as Canada, Australia, Jordan, and Vietnam.
Future Outlook
With the development of precision agriculture and green farming, hypochlorous acid irrigation technology is expected to become a standard practice in global agriculture. Chlory is promoting the widespread adoption of this technology through continuous innovation, helping agricultural producers ensure food security in a more sustainable manner.
Integrating Chlory's hypochlorous acid generators will not only improve production efficiency and crop quality, but also reduce reliance on chemical pesticides, moving towards a more eco-friendly future.
Specific application needs to be adjusted according to local agricultural regulations and water quality conditions. It is recommended that implementation be carried out under the guidance of agronomists.
