LETTERS: WORST TIME FOR RAGWEED IS MIDMORNING

To the editor:

I appreciated the opportunity to be quoted in your Sept. 10 newspaper article concerning ragweed pollination and hay fever. However, the article contains misinformation regarding ragweed pollination.

It is not true that "levels are highest by late afternoon and early evening." In fact, ragweed pollination occurs during the early daylight hours, and levels of pollen peak in midmorning.

If there is any good time for the ragweed sufferer to go outside during this season, it would be preferable to go outside in the afternoon or during windless periods.

I point this out as being a solitary problem in an otherwise excellent and informative article.

I hope this information will be of help to you.
