Paraquat is one of the most widely used and dangerous industrial herbicides on the market today. It is used to control grass and weeds in many agriculture and non-agriculture sites. Many farmers apply paraquat to kill weeds before planting crops such as peanuts, corn, and soybeans, or as a drying agent for cotton and tobacco. It is also used at power sub-stations and along railroad tracks to clear all vegetation. 

Studies have shown that exposure to this weed killer through the skin or by inhalation can lead to Parkinson’s Disease. Paraquat is so dangerous that it has been banned in many countries worldwide. However, it is still being used in the United States even though regulators have restricted it to commercial use only. Companies like Syngenta, Growmark and Chevron continue to make and sell paraquat, and are raking in profits of over $600 million per year. Paraquat herbicide should not be confused with Roundup. Roundup’s active ingredient is glyphosate which has been linked to non-Hodgkin’s lymphoma, while experts have linked paraquat exposure to Parkinson’s disease.
