Asthma and pesticides [Letter]

Regarding your editorial on the health risks of pesticide use, asthma was once thought to be caused by pesticides, but the link was later disproved ("Understanding pesticide risks," Feb. 20).

According to recent studies by the National Institutes of Health, asthma is caused by allergens and genetics. The list of allergens includes cockroaches, rodents, dust mites, dogs, cats, molds and fungi -- but not pesticides.
