The interaction of the root lesion nematode Pratylenchus penetrans and fungal plant pathogen Verticillium dahliae causes potato early die (PED) complex, which induces premature vine senescence dramatically reduces yield in potatoes. Management PED is often achieved through use soil fumigants nematicides, but their adverse effects on soil, human environmental health, strict regulations worldwide require alternative control tactics. In this study, we investigated multiple composts manures...

Bare-root production of Hemerocallis spp., daylily, is major economic importance to Michigan's ornamental industry, but clean nursery material challenging due plant-parasitic nematodes. The northern root-knot nematode, Meloidogyne hapla, the most important perennial pathogen in North America; it causes over 20% yield loss spp. and reduces marketability distribution. A field trial was established 2018 2020 at a Michigan commercial determine effective long-term management strategies reduce...

Michigan has the third largest floriculture industry in United States, with production of daylily (Hemerocallis spp.) a top commodity. Daylily is one most economically important ornamental plants, yet their plagued by plant-parasitic nematodes, especially northern root-knot nematode, Meloidogyne hapla. Based on previous field trials, seven treatments combination high-carbon, cow manure compost were selected for three-year trial at commercial nursery Zeeland, MI to discern best M. hapla...

Potato yields are significantly impacted by soil-borne diseases such as the root-lesion nematode, Pratylenchus penetrans. Traditional management strategies involve soil fumigation with broad-spectrum pesticides, metam sodium, and post-planting applications of non-fumigant nematicides, including oxamyl fluopyram. In Michigan, approximately 35% potato hectares treated 50-60% amended customized manure-based composts. Considering critical impact this nematode on industry, along potential future...

In this two-year field study, the impacts of pre-plant soil management strategies, including fumigation, nematicide application, and organic amendments, on growth nematode community dynamics cherry cultivars ‘Emperor Francis’ ‘Ulster’ grafted to ‘Mahaleb’ rootstock were investigated in a replanted orchard site. first year, fumigation with 1,3-dichloropropene – chloropicrin mixture (Telone C-35) led significantly increased trunk cross-sectional area canopy height both cultivars. Pratylenchus...

Summary Nematode parasitism is a yield limiting factor in many cropping systems, including potato production, which can translate into substantial economic losses. These impacted financial returns are simply calculated by subtracting the cost of production from total revenue (yield times price per potatoes). The costs include, but not limited to, chemical and biological control agents. To assess associated with different nematode management strategies, we evaluated complete estimations for...

Abstract Plant-parasitic nematodes (PPNs) can cause substantial economic yield losses to many agronomic crops in the United States. A regional-scale survey was completed across 20 counties determine PPNs prevalence Michigan corn and how factors such as soil type, tillage, irrigation, cropping systems influence their distribution. Ten different major genera of were identified fields: Longidorus (needle), Helicotylenchus (spiral), Pratylenchus (lesion), Meloidogyne (root-knot), Heterodera...
