abstract = { Two commercial greenhouses producing potted plants in Pennsylvania (PA) using recycled irrigation water in an ebb-and-flood system have incurred significant crop losses due to Pythium aphanidermatum. In cooperation with the greenhouses, one or more of their water tanks were monitored continuously (128 tank samplings) for Pythium by baiting. Nine species of Pythium and three species of Phytopythium were recovered, representing Clades A, B, E, and K but none was P. aphanidermatum. The recovered Pythium species were: 1) P. rostratifingens, 2) isolates identical to P. sp. nov. OOMYA1702-08 (Clade B2), 3) P. coloratum, 4) P. middletonii, 5) and 6) two new species in Clade E2, 7) a new species in Clade B2, 8) isolates very similar to P. sp. nov. OOMYA1646-08 (Clade E2), and 9) a new species in Clade A. The Phytopythium species recovered were: 1) Ph. litorale, 2) Ph. helicoides, and 3) Ph. chamaehyphon. This paper illustrates the different communities of Pythium and Phytopythium species found in each greenhouse over ten months. Some of the baited species display resistance to the Oomycete fungicide active ingredient, mefenoxam. Ph. helicoides and the new species in Clade B2 were pathogenic on seedlings in potting mix with fertilizer added.}
