Download PDF The landscape for managing rhizoctonia in potatoes has changed significantly over the past two years. CPM looks at the latest advice on protecting marketable yield from this damaging disease. It’s all about protecting yield, protecting size distribution and protecting tuber numbers.

Some old favourites in the crop protection armoury have fallen foul of the hazard-based regulatory system adopted by the EU in 2009. But growers still have fungicide options for control of rhizoctonia and stem canker, even though there have been casualties in this area, and control starts long before the planter rolls into the field. There are three windows for treating potato seed for rhizoctonia – when it’s graded at source, soon after it arrives on farm or at planting. Some will have seed delivered ‘just-in-time’, which lends itself to powder treatment on planter. But there’s a move away from that approach, with agronomists increasingly favouring early treatment with liquids. And the signs are that growers are acting on that advice. Rhizoctonia solani is a problem most growers will…
