Fungi associated with sugar beet cyst nematode (Heterodera schachtii Schmidt) in W. Azerbaijan were isolated from different stages during 2002-2004 and studied. Some 300 fungal isolates were obtained. In this paper, 16 species belonging to nine genera are identified. Among them, three species viz. Lecanicillium aphanocladii, Myrothecium verrucaria andPlectosporium tabacinum are as new records t...

Hirsutella minnesotensis [Ophiocordycipitaceae (Hypocreales, Ascomycota)] is a dominant endoparasitic fungus by using conidia that adhere to and penetrate the secondary stage juveniles of soybean cyst nematode. Its genome was de novo sequenced and compared with five entomopathogenic fungi in the Hypocreales and three nematode-trapping fungi in the Orbiliales (Ascomycota). The genome of H. minne...

Hirsutella rhossiliensis OWVT-1 has substantial potential as a biocontrol agent against plant-parasitic nematodes. Serine proteases have emerged as a potentially useful factor in the nematode-fungus interactions. When grown in liquid culture with the nematode Panagrellus redivivus as the sole nitrogen source, an extracellular alkaline protease (Hasp) was produced by the OWVT-1. The purified Has...

Several weeds serve as alternative soybean cyst nematode (SCN) hosts. Still, the relative reproductive capacity of SCN HG types (Heterodera glycines type) on weed hosts to is not well understood. This study examined reproduction three South Dakota endemic populations—PSCN-1 (HG 0), PSCN-2 2.5.7), and PSCN-3 7)—on purple deadnettle, field pennycress, henbit. The Relative Female Index (RFI) was c...
