This process can take up to 10 years and involve more than 120 different tests and studies. There is no scientific evidence that golfers face any chronic health risks from the pesticides used to maintain courses. Once a liquid product is applied and the turfgrass is dry or the product has been watered in, there is very little chance of exposure to golfers or others who enter the area. It is worth noting that a small percentage of people may be allergic to a particular product, just as some people are allergic to household cleaners, soaps or perfumes. Golfers with possible chemical allergies are always encouraged to contact superintendents to find out what products might be in use.
Applicators work directly with pesticides and are exposed much more often than golfers.
Consider the fact that it is safe for a person to have an occasional X-ray, but the technician may actually leave the room to prevent repeated exposure. These precautions may include the use of rubber gloves, goggles, respirators or protective clothing. Some media stories suggest that pesticides are linked to cancer. Most of the product testing required by EPA focuses on this question. They also said lifestyle choices such as smoking, dieting and stress were the most significant factors in the results.
