Diquat herbicide, the most important ingredient is paraquat. As for how long it takes to die after poisoning, it has something to do with how much dose the patient took. According to the lethal dose of paraquat, it is usually like this: if the dose taken is less than about 10ml, and the treatment is active and through a series of hemodialysis and other methods of treatment, it can survive and will not die. If you take between 20-50ml, you will die in about a week clinically. If a large amount of oral dose exceeds 50ml at one time, death may occur within 1-2 days. Therefore, if you are found to have taken it by mistake or otherwise caused poisoning, you should immediately remove the poison, give prompt treatment such as emetic, as well as gastric lavage and diarrhea, and promptly send it to the hospital for resuscitation treatment.
