Removal of Residual Pesticides by NEOCL-ClO2
- In conclusion, the result of this study is to remove residual pesticides from agricultural products such as lettuce,
- it is shown that washing with chlorine dioxide is more desirable in terms of food stability.
- As a result of this study, chlorine dioxide treatment can be used as washing water to remove residual pesticides from fresh products
Sterilization in Agriculture Field
Chlorine dioxide has a wide range of control against crop diseases in agriculture.
Excellent control effect against viruses and bacteria, and selective control effect by mold type even for mold control
|strain||ClO2 concentration (dilution)|
|Rhizoctonia solani||no spore|
|Sclerotinia sclerotiorum||no spore|
|Cylindrocarpon destructans||no spore|
Soil mildew suppression and disinfection
Excellent soil mildew suppression ability compared to chemical pesticides in soil irrigation It is very effective in controlling plant disease from soil before growing and growing crops.
Results of Treatment of Ginseng Soil in Hwaseong Area NEOCL ClO2 is better than sapphire pesticide It showed a higher inhibitory effect of 67%.
Treatment of ginseng soils in Icheon area with direct soil ginseng damaged soils. NEOCL ClO2 showed higher inhibitory effect than sapphire pesticides
Ginseng soils in the Eumseong area were treated with NEOCL ClO2 and showed a similar or higher inhibitory effect than sapphire pesticides..

Residual Pesticides Reduction
Globally, chemical pesticide reduction policies are being strengthened due to human toxicity and ecological toxicity, and agricultural pesticide contamination problems are emerging as a recent issue. Chlorine dioxide has the function of reducing residual pesticides, so it has a very high market prospect in the field of washing crops, soil and harvested agricultural products after cultivation.
- NeoCLReducing residual Pesticides
ChlorpyriposIt is the main component of pesticides and is classified as organophosphorus pesticides. It is a toxic substance that thermally decomposes to release chlorides / nitrogen oxides / cyclic compounds / phosphates.
DiazinonIt is the main component of pesticides and is classified as organophosphorus pesticides. It is mainly used for spider webs, aphids, mites, moths, and insects.
MetalaxyIt is a major component of pesticides and is classified as a phenylamid pesticide. It is mainly used for late blight, fish, and bacteria.
Nationally recommends chlorine dioxide fumigation methods to solve the problem of pesticide treatment prohibition and egg disinfection methods.
(99.9% disinfection of AI infected eggs exposed to chlorine dioxide gas for 30 minutes)
Disinfection of shrimp white spot virus and yellow head virus confirmed virus death
- Treatment with chlorine dioxide at low concentrations had no effect on salinity, pH, alkalinity, dissolved oxygen, and phytoplankton, and vibrio proved to be significantly reduced.
After using low chlorine dioxide, the white spot virus and the yellow head virus were eradicated when the effective concentration was maintained.
(white-spot virus (WSV))
Chlorine dioxide replacement for dry lavar and aquaculture sterilization (wastewater treatment)
Sodium hypochlorite and inorganic acids is currently used for the lavar farming and treatment of wastewater from processing, As they produce harmful by-products after sterilization, they will be replaced by chlorine dioxide, an eco-friendly oxygen disinfectant.
Environmental Impact Assessment of ClO2-Fish Toxicity
Intensive observation of fish after 4 test of chlorine dioxide :1st (low concentration / 10L), 2nd (high concentration / 10L), 3rd (high concentration / 10L), 4th (large concentration / 10L)
Even if the concentrated ClO2 aqueous solution was dispersed in an isolated lake, it was confirmed that there were enough livestocks , even though it was ClO2 aqueous solution.
Disinfection effect is shown even if high concentration is dropped due to its easy decomposition characteristics, and it is confirmed that no residue is generated (below 1 ppm), as it is completely decomposed within 4 to 5 minutes.

Survival Rate of Flounder Exposed to ClO2 Treated Seawater
"Once treated at various concentrations of ClO2 and exposed to flounder for 10 minutes. At the residual concentration of 0.27 ppm immediately after ClO2 treatment,
Survival rate was 100%… . "
Survival Test of Fish Using Chlorine Dioxide (ClO2)
Experiments using chlorine dioxide (ClO2) treated seawater showed that the flounder had a 100% survival rate at 0.2 to 0.3 ppm and relatively high survival rates for rockfish and eel at high concentrations.

comparison of fish toxicity with NEOCL-ClO2
In the case of copper compound, which is the most commonly used flocculant for removing algae, the test results show that the toxicity of fish is considerably higher than chlorine dioxide.

Case of Chlorine Dioxide Application to Fishery
- Total Volatile Nitrogen(TVN)
- Most people don't know that the inherent smell of fish, shrimp, and other fish on the market is the product of these decaying processes.
One of the methods of measuring grade drop due to corruption or deterioration is the Total Volatile Nitrogen value (TVN).
Volatile nitrogen (TVN) is due to ammonia gas from the decomposition of proteins. Fresh fish and shrimp caught in the ocean or pond have TVN concentrations of 4-7.
As TVNs increase (due to the breakdown of fish and shrimp protein), the smell also increases.
In Europe, consumers generally require chemical treatments to achieve a TVN concentration of around 50.
If the TVN concentration is above 100, it is unsuitable for human consumption, so it can be used only for dog or cat food.
If you store your harvested fish or shrimp on ice containing chlorine dioxide, your TVN concentration will be around 17 and it will be almost odorless !!
