Regional Notes

You'll see stubby-root nematode damage as extremely short, fine roots with a yellow to brownish cast, causing plant stunting. Affected plants look poor despite adequate water and nutrients. Plant in fields with low population densities where possible. Good site selection and resistant varieties offer the best long-term solution. Monitor roots carefully for early detection of infestation. Nematode management requires careful attention to soil conditions and host selection, as these microscopic pests cause significant damage wherever they occur.

Plant in fields with low population densities. Fallow the year prior to planting. Remove infected material promptly and improve growing conditions to limit pathogen spread. Good sanitation, adequate spacing, and proper irrigation practices reduce disease pressure over time.
