Problem one: what is TCCA and chlorobromoisocyanuric acid distinction?
There is little difference between TCCA and chlorobromoisocyanuric acid, and their physical and chemical properties are almost the same.Both release halogens to form oxidizing weak acid oxidases that block DNA synthesis. At the same time, the intermediate is used to infiltrate into the plant to kill bacteria.After the decomposition of TCCA into hypochlorous acid, the intermediate has triazine trione, homtriazine, homtrione; Chlorobromoisocyanuric acid decomposition into hypochlorous acid, hypobromic acid intermediates have triazine dione, triazine, from the killing of the same unit of bacteria used in the amount of experimental data show that trichlorobromoisocyanuric acid sterilization ability is slightly stronger than chlorobromoisocyanuric acid. This is why PD certificates currently contain 36% and 42% TCCA and 50% TCCA.
Problem two:TCCA and chlorobromoisocyanuric acid why can be used in agriculture? Bactericidal ability?
Because TCCA and chlorobromoisocyanuric acid itself is extremely good fungicide, mainly used for medical health disinfection before it. Because of its bactericidal spectrum, there is no selectivity to bacteria, viruses and fungi. So these products treat crop diseases quickly. Dilution of more than 800 times of rice and other crops are generally safe greenhouse crops are generally 1000-1500 times more than is also safe fruit trees and flowering 2500-3000 times safer. Dilution this high, will it work? For example, 84 disinfectant has only 5-6% active content, and it needs to be diluted 250 times to sterilize tableware and hotel linens. All kill germs in 10 minutes Trichlorochlorine and chlorobromo are basically 20 times of 84 disinfectant, which can be diluted to 250*20 and the highest dilution to 5000 times. They still have very good bactericidal effect (this is why during the outbreak of SARS in 2003,TCCA was suddenly designated by the Ministry of Health as public prevention and control drugs).
Problem three:TCCA and chlorobromoisocyanuric acid agricultural use safety?
The physical and chemical properties of TCCA and chlorobromoisocyanuric acid are relatively stable, so the storage and agricultural use alone are safe, harmless to human body. No residue of liquid medicine is suitable for pollution-free agriculture. But since both are oxidative fungicides there is no problem mixing with fungicides. But with organophosphorus pesticides and sodium dihydrogen phosphate and other direct mixing will react, so it is not recommended to mix the general two diluted with pesticides, micro fertilizer is very safe (because pesticides may have recessive organophosphorus).
Problem four: can TCCA and chlorobromoisocyanuric acid cause cancer?
Trichloroisocyanuric acid and chlorobromoisocyanuric acid are harmless fungicides chlorine, bromine and other bactericidal components after ionization body decomposition into ammonia, carbon dioxide, water. So as you can see from this process, it has no residue and it doesn't cause cancer. If chlorine can cause cancer, then the salt we eat every day (sodium chloride) is not safe. Trichlorochlorine and chlorobromine are used in drinking water in Europe and the United States to kill microorganisms, bacteria and viruses in tap water, so they are safe to use. Domestic application still calculate common many fungus spirit is cancer-causing medicaments, euramerican country is forbidden to use.
Problem five:TCCA and trichlorobromine cyanuric acid agricultural application, which effect is good, at what respect disease is good? Is there resistance?
Theoretically TCCA is better than chlorobromoisocyanuric acid in bacterial disease and fungal disease, and the effect is faster. Chlorobromoisocyanuric acid has good effects on bacteria and viruses, but it is slower than TCCA, because the decomposition and release process is different and you can find that there is really no difference between the two, similar. Both are effective for bacterial diseases, and leaf, stem and root rot diseases are also very good. It is suitable for fusarium wilt, verticillium wilt, bacterial stripe, bacterial blight, rice blast, vine blight, standing blight, leaf spot disease, root rot disease, anthrax, ulcer disease, scab disease, wheel grain disease, virus disease and other diseases with good effect. It's a drug with flaws, or it's a miracle drug. Clearly TCCA and chlorobromoisocyanuric acid are not magic drugs! Some diseases are suitable for combination,TCCA or chlorobromoisocyanuric acid can quickly stop crop diseases. The other ingredient starts healing. So some diseases are not suitable for single TCCA and chlorobromoisocyanuric acid, such as grey mold, white powder, etc.. In terms of resistance, is there resistance to disinfecting water? No! So trichloro and chlorobromine are not resistant. So the fear of resistance or some of the resistant fungicides mixed with trichloro and chlorobromine work very well because of that.
