Phytophthora nicotianae: Fungicide Sensitivity, Fitness, and Molecular Markers
Mefenoxam has been a premier compound for Phytophthora disease control in the nursery industry for 30 years. The primary objectives of this research were to examine whether Phytophthora species have developed resistance to this compound and to investigate fungicide resistance management strategies. …

Evaluation of Rhizoctonia solani - Heterodera glycines interactions on soybean
… and the mean SCN Rf value in pots containing the mefenoxam + abamectin treated seed was not different from the mefenoxam-only control. Average lesion ratings were lowest for seeds treated with mefenoxam + sedaxane + abamectin. Lesion ratings in the mefenoxam + sedaxane treatment were not different …

Fungicide Sensitivity of Erysiphe necator and Plasmopara viticola from Virginia and nearby states
… but none were resistant to mefenoxam. Eighty-two percent of the PM isolates were QoI-resistant, but none were resistant to boscalid and quinoxyfen. The frequency of the G143A point mutation, which confers high levels of QoI resistance, was quantified in DM and PM isolates by …

Characterization of oomycete species causing soybean diseases in Illinois and management applications
… Phytophthora spp. were sensitive to metalaxyl, mefenoxam, azoxystrobin, and ethaboxam. There were Pythium isolates insensitive to azoxystrobin and ethaboxam.

Ecology and Management of Pythium species in Float Greenhouse Tobacco Transplant Production
… Pythium control trials identified ethaboxam, mefenoxam, and copper ionization as potentially promising alternatives to etridiazole for Pythium disease management in tobacco transplant production. The outcomes of this project provide useful new information to better understand the composition, …

Characterization, development of a field inoculation method, and fungicide sensitivity screening of the Pythium blight pathogen of snap bean (Phaseolus vulgaris L.)
… hydroxide at 100μg/ml, and the lowest GR on mefenoxam-amended medium was 91.9%. At 100μg/ml cyazofamid, all P. deliense isolates were completely sensitive and variation was observed in P. aphanidermatum isolates. At 100μg/ml potassium phosphite, significant GR similarities were recorded …

Effect of fungicide seed treatments on Fusarium virguliforme and development of sudden death syndrome in soybean
… were reduced by a treatment combining mefenoxam + thiophanate-methyl + azoxystrobin + B. pumilus + prothioconazole + fludioxonil compared to the non-treated control; however, the reduction in Fv DNA did not improve root growth or decrease SDS foliar symptoms compared to the non-treated …
