Potato growers in the UK are facing challenges in weed control due to delayed planting caused by a wet March, which saw 80% more rainfall than usual, according to a news report by FarmingUK. This prevented planters from working and kept seed stocks in storage. South west and south east England were the most affected, while the north faced frosts and snow.
Corteva Agriscience notes that planting is now in progress, but maincrop potatoes are likely to be drilled later than intended. Persistent April showers may have also disrupted the application of residual herbicides.
Most weed control in potatoes involves residual chemistry applied after planting, with post-emergence sprays typically used in May for any remaining weeds. Craig Chisholm, Corteva’s field technical manager for potatoes, said there were three main reasons why weed control was important in potatoes, the most important reason being to keep weeds in check is to reduce the risk of blight through sheltering leaves or contributing to a more favourable microclimate.
