Agent Orange. In this country 2 4 5T is the equivalent of what was called Agent Orange. The big difference is that Agent Orange had dioxins in the herbicide. They were not removed when the government purchased the herbicide. (Agent Orange was a code name for defoliating the jungle). It is not an herbicide of any particular kind. 2 4 5T or 2 4 D most likely were used to get rid of the weeds and brush. Neither of those two herbicides contained dioxins. Agent Orange did.

Herbicides used excessively and recklessly per Viet Nam at least 13 times the recommended rate, is going to cause and did cause serious problems. The problems of that spraying still persist today. Remember, it was 13 times the recommended rate of the USDA.

DDT, I remember it well. We would be at drive in movies and they would be spraying it. We sprayed it on the cattle for insect control. Just about all the World War II veterans had a powder with DDT in it that they used for lice, bed bugs, any kind of insect. Probably a third of those vets escaped serious health effects that would have been caused by the insects if DDT had not been used. As with many things DDT was abused and it did cause serious problems with birds, etc.

Dej I am sorry for all the trouble you are having. Hopefully, you will get better and better.
