Potatoes Pest & Disease Programs — Biological Inputs That Fit Your Spray Window
Natural program for potatoes — root-knot (incl. Columbia) nematodes in the root zone and early and late blight above ground, at zero PHI/REI.
Growing potatoes with Vegalab
Potatoes face soil-borne pressure from root-knot nematodes (including Columbia root-knot) that gall roots and tubers, plus early and late blight above ground.
Vegalab's Nematode Control targets the nematodes in the root zone, and Spore Control covers the blights — a natural program with zero pre-harvest interval and re-entry. Rates follow the registered label.
Vegalab potatoes program
| Vegalab product | Target (pest / disease) | Rate | PHI / REI |
|---|---|---|---|
| Nematode Control | Columbia & other root-knot nematodes; galling on roots and tubers | Soil, 1–3 gal/ac per label | 0 / 0 |
| Spore Control | Early blight, late blight (phytophthora), damping-off | Foliar, per label | 0 / 0 |
In a University of Idaho microplot study on Columbia root-knot nematode (cv Ranger Russet, 2013), higher rates of Nematode Control significantly reduced final nematode populations and tuber galling versus the untreated control and a conventional standard, with higher yield at lower rates.
Frequently asked questions
Does Vegalab control Columbia root-knot nematode on potato?
Yes — Nematode Control is a natural, micronized nematicide applied to the root zone to reduce root-knot populations and tuber galling; it has been evaluated in university microplot trials.
What controls potato blight naturally?
Spore Control (thyme oil) is Vegalab's natural fungicide for early and late blight, applied preventatively ahead of favourable weather with zero PHI/REI.
