Hypochlorous acid (HClO) is a weakly oxidizing inorganic acid and a highly effective disinfectant. It kills pathogens and prevents infectious diseases by oxidizing and removing organic matter and microorganisms.
The main function of hypochlorous acid:
Disinfection: Hypochlorous acid can kill a variety of bacteria, pathogens and fungi, and has a high effect against the spread of diseases. It breaks down microbial cell walls and enters the cell interior to kill the cell.
Purification of water sources: hypochlorous acid can kill bacteria and pathogens in water sources, purify water quality, thereby preventing water source pollution and the spread of infectious diseases.
The use of hypochlorous acid to disinfect lawns has the following advantages over the use of fungicides:
Hypochlorous acid has the characteristics of low toxicity, low irritation and not easy to form harmful residues, and is relatively safe for humans, animals and the environment. However, some chemically synthesized fungicides may be harmful to humans and the environment, and excessive or improper use may even cause poisoning.
The price of hypochlorous acid is relatively low, and only 3kg of salt and 8kw of electricity are needed to produce 1 ton of disinfectant. Therefore, the economic cost of using hypochlorous acid for lawn disinfection is lower than that of fungicides, and it is more suitable for the disinfection of large-scale lawns.
Hypochlorous acid has a broad-spectrum bactericidal effect, which can remove bacteria, viruses, fungi and other microorganisms. However, some fungicides may have a single effect or have high tolerance to them, so they cannot effectively disinfect a variety of bacteria.
Hypochlorous acid can be decomposed into water and oxygen while exerting a bactericidal effect, and there is no pollution problem caused by difficult degradation. However, some fungicides may remain in soil and water sources, potentially affecting the environment.
After the hypochlorous acid is sprayed, it directly contacts the surface of the lawn, and it will not enter the grass through the roots like other fungicides, which reduces the damage to the lawn. However, some fungicides have strong bactericidal power, which may cause damage to the lawn, causing leaves to turn yellow, shrink and die.
When using hypochlorous acid to disinfect the lawn, it should be sprayed according to the following steps:
1.clean up the weeds and dead leaves on the lawn, and keep the surface of the lawn dry and ventilated.
2.The concentration and amount of hypochlorous acid solution should be adjusted according to the size of the lawn and disease conditions to achieve a good disinfection effect and avoid damage to the lawn. Generally speaking, use 50~100pm hypochlorous acid solution to disinfect the lawn.
3.Use a sprayer or watering can to evenly spray the hypochlorous acid solution over the lawn surface, covering as much of the grass blades and soil surface as possible. It should not be oversprayed so as not to affect the growth of the lawn.
4.After spraying, the hypochlorous acid solution should be allowed to dry on the surface of the lawn, and do not wash or spray with water. At this time, people and animals should be prohibited from entering the lawn.
5.Special attention should be paid to the fact that when using hypochlorous acid for lawn disinfection, avoid spraying on trees, flowers, flower beds and other places around the lawn to avoid adverse effects on surrounding plants. In addition, care should be taken to protect your own safety and avoid direct contact with hypochlorous acid solution or inhalation of gas.
Develop a lawn disinfection plan based on lawn type and climate
1. Tropical lawn
Tropical lawns usually grow in high-temperature and high-humidity environments, which tend to accumulate bacteria and fungi. It is recommended to use 100ppm hypochlorous acid solution for disinfection. Spraying every two weeks can effectively kill bacteria and fungi on the lawn surface.
2. Temperate lawns
Temperate lawns, which typically grow in warm, humid environments, are also prone to accumulating bacteria and fungi. It is recommended to use 100ppm hypochlorous acid solution for disinfection. Spraying every other month can effectively prevent the lawn from contracting diseases.
3. Boreal lawn
Boreal lawns typically grow in cold, dry climates and are less susceptible to bacterial and fungal infections. However, in the spring and fall, when the temperature changes greatly, the lawn is prone to diseases. It is recommended to use 50ppm hypochlorous acid solution for disinfection and spray every two months.
4. High Altitude Turf
High-altitude turfgrass typically grows at higher elevations, where temperatures are cooler and are less susceptible to bacterial and fungal infections. However, the summer sun is more intense, and the lawn is prone to sunburn and sunburn. It is recommended to use 50ppm hypochlorous acid solution for disinfection, and spray every other week in summer, which can effectively prevent sunburn and sunburn on the lawn.
In general, the lawn disinfection program should be adjusted according to the lawn type and climate environment. When implementing a lawn disinfection plan, attention should be paid to the concentration of the solution and the method of use to ensure the disinfection effect and safety of the lawn. At the same time, lawn disinfection is only one of the preventive measures, and lawn maintenance and management are also very important.
