P-San (Peroxide Sanitator)

Nobody wants to spend more than necessary on crop disinfectant products. But if the situation calls for it, it’s nice to know that there are effective products available. There are many option in agriculture disinfectants to be applied, some of the more popular disinfectants include phenols, chlorine, peracetic acid, hydrogen peroxide, quaternary ammonium compounds and aldehydes. Peracetic acid is one of microbiocide developed for bacteria,slime, odor and algae control in agricultural waters. When peracetic acid dissolves in water, it disintegrates to hydrogen peroxide and acetic acid, which will fall apart to water, carbon dioxide and oxygen which creates a highly toxic environment for anaerobes . Peracetic acid degradation products are non-toxic and can easily dissolve in water. It is grouped as one of the High Level Disinfectant. PaaThe disinfection efficacy on microorganisms can be ranked as: Bacteria>Viruses>Bacterial Spores>Protozoan Cysts. A comparative assessment of the disinfectants are reviewed above in Table I. This assessment is aimed at facilitating the efficacy of the right product for the type of organism. One article (talkcleantome.blogspot) wrote that peracetic acid to be…

  • bactericidal at 10ppm
  • fungicidal at 30 ppm
  • virucidal at 400 ppm

in a 5-minute contact time on hard surfaces . Furthermore, it is sporicidal at concentrations of 3000 ppm. Organic matter can reduce the bactericidal effect of peracetic acid, and the concentration of Peracetic acid required to kill bacterial spores need to be increased by 2 to 3 times. Overall, as a disinfectant, Peracetic Acid is one of the favorable choices available to be used in almost any sector.

How does peracetic acid disinfection work ?
Peracetic acid is NOT systemic bactericides. The mode of action is by oxidation. Peracetic acid as a disinfectant oxidizes the outer cell membranes of microorganisms. The oxidation mechanism consists of electron transfer. When a stronger oxidant is used, the electrons are transferred to the microorganism much faster, causing the microorganism to be deactivated rapidly.

However, pH and temperature do influence peractetic acid activity. Peracetic acid is more effective when the pH value is 7~8 (alkaline PAA solutions). EnviroTech has found that PAA solutions are unexpectedly effective at higher pH ranges and provide significant benefits.”CLICK HERE

pH 8 and pH 9 outperform the low and high pH ranges of 5 and 10

The bactericidal effect increases with temperature. Between 10°C and 30°C, in every difference of 10°C, the sterilization effect differs by 1.2 to 5 times. At a temperature of 15 °C and a pH value of 7, five times more peracetic acid is required to affectively deactivate pathogens than at a pH value of 7 and a temperature of 35 °C.

Optionally, Peracetic acid can be SEPERATELY integrated with powerful infection-fightingsilver.jpg qualities of ionic SILVER Nano particles. Silver majorly has few roles … Activator and Oligo dynamic action. This combination yields synergistic effect several orders of magnitude more powerful compared to the effect of either agent. Silver ions are active against a broad range of gram-positive and gram-negative bacteria. Nevertheless, silver resistant strains of microbes are evolving. It is therefore interesting combining silver compounds with a peroxide of a combination of peroxides to prevent resistant formation. The main advantage for using silver compounds is the persistent antimicrobial activity over a wide pH range.

Drip Irrigation System Cleaning:
To clean slime and algae from drip system tapes and emitters, meter this product    60~120ml/1000 liters of water. When required, during normal irrigation cycles, use this product at the recommended dose for a minimum of 30minutes. After an irrigation cycle do not flush the lines.

Apply this product to ornamentals, bedding plants, vegetable plants, flowering plants, shrubs, and trees. To ensure that this contact fungicide is effective, thorough coverage and wetting of the foliage is necessary.

Care should be taken when using this product for curative control of obligate organisms living on the plant tissue (such as downy and powdery mildew). These treatments may result in lesions on plant tissue. This product will oxidize parasitic organisms living in plant tissue that are not always visible to the naked eye. Resulting oxidative effects may include spotting, or drying of the plant tissue where organisms inhabited tissue.

Initial Application:
1. Use 600~1200ml/1000 liters of water. Do not reuse already mixed solution, make fresh daily.

2. Spray, mist or fog plants in early morning or late evening.

3. Thoroughly wet all surfaces of plant, upper and lower foliage, including stems, branches and stalks to ensure full contact with the plant and flower tissue.

4. Apply consecutive applications until control is achieved and then follow directions for preventative treatment.

Weekly Preventative Treatment:
1. Use 400ml/1000 liters of water . Do not reuse already mixed solution, make fresh daily.

2. Spray, mist or fog plants.

3. Thoroughly wet all surfaces of plant, upper and lower foliage, including stems, branches and stalks to ensure full contact withthe plant and flower tissue.

4. Spray every five to seven days as a preventative treatment.

At the first sign of disease spray daily with 600~1200ml/1000 liters of water for 3 consecutive days and then resume weekly preventative treatment. Manufacturer’s recommendation 4ml/liter is the maximum dosage.

A widely known alkaline composition such as potassium hydroxide can be used as a pH-adjusting agent for adjusting the pH of the peracetic acid, ideally treatment solution in range pH 7~8 is recommended in agriculture application.

A nonionic spreader (surfactant @ 0.01%) adjuvant may be added in foliar application since conidia are hydrophobic (water repelling). P-San is clear, colorless liquid (pungent vinegar-like odor).

Peracetic acid containers should be made of non-metallic materials as much as possible. During the storage process, a large amount of gas can be generated due to decomposition. Therefore, they can only be packed in dark-color polyethylene plastic barrels (bottles). Fill up the capacity up to 80% of the container. All kinds of packaging containers should have vents made of functional materials that are breathable but do not leak liquid. Avoid exposure of sunlight or heat during storage or transportation. Due to its nature is unstable, it can release oxygen at room temperature, spontaneous combustion, burning or explosion in the event of open flame or high temperature.

    For verticillium and fusarium : Use concentration yields a minimum of 500 ppm of active peracetic acid with high biocidal activity. This concentration is sufficient to control most common diseases. Spray this concentration in direction from bottom of plants to above. Repeat this step, three times with a 3 to 7 days interval between the applications.

    For heavily infected roots and related diseases : use concentration provides 500 ppm of active peracetic acid. Apply it with the last 15 minutes of irrigation. Try to treat the infected roots of plants with this concentration. Repeat this irrigation step, two times with a 3 to 7 days interval between the applications.

    Microbiocidal Activity of Peracetic acid …
    Bacteria : PAA will inactivate gram-positive and gram-negative bacteria, fungi, and yeasts in <5 minutes at <100 ppm. In the presence of organic matter, 200-500 ppm is required.

    Bacterial spores in suspension are inactivated in 15 seconds to 30 minutes with 500 to 10,000 ppm (0.05 to 1%)
