hi . iam vonn murray high school principal in texas. My dad was a crop duster in the 1960's in Texas and I remember heavy unregulated usage until the feds stepped in . My cousin who is a chemist at the Univeristy of Idaho may have ome interests in this also. At age 62 my dad was healthy and ran and played golf and 1 year after a car wreck he began to get dizzy and it worsend over the summer. He visited several local doctors to no avail. He visited Scott and White in Temple , tx a univ. of Tx A &m research hospital where they said it was parkinsons, we asked for 2nd opinion and gothe same. We than traveld to Houston texas to see Dr. Jankivic who labled it a rare form of parkinsons Multiple System atrophy. In two short years he has become a complete vegetable. Most Dr. said ther was not much research to indicate that pesticide exposure was a cause but could be an influence. I agree. But i also realize that his involvment was for about 10 years without side effects, but what about long term later problems. Was any one crop dusting with the pesticides of the 1950 and and 1960's in 1800 and early 1900 to really study over a oong window? [log in to unmask] I am not a typist sorry!
