Abstract
Airborne spores of F. moniliforme were found in 2 asparagus fields in western Massachusetts [USA]. F. moniliforme was isolated from female flowers, fruit and seed of plants growing in commercial fields. Vascular colonization was not found in branchlets bearing contaminated flowers or fruit. F. moniliforme also was isolated from 1-yr-old volunteer asparagus plants, which originated from fallen fruit of the previous growing season. Airborne spores of F. moniliforme apparently are the source of contamination of asparagus flowers, fruit and ultimately, the seed.
