Dry spell may alter potato herbicide strategies this spring

Written by Charlotte Cunningham from CPM Magazine

Potato growers may have to rethink their usual reliance on pre-emergence herbicides this year after a period of dry weather, according to the latest advice from Corteva. While planting has progressed well thanks to favourable conditions, the dry soils will have a negative impact on the efficacy of the pre-emergence weed killers typically applied to ridges shortly after planting. Craig Chisholm, Corteva Agriscience field technical manager, says leaving weeds unchecked can reduce yield, slow down harvesting machinery and increase the risk of blight. “Dry soils can crack or slip down the ridges, disrupting the all-important seal required for optimum efficacy from pre-emergence herbicides. As a result, rain or planned irrigation in the next few weeks will stimulate weed growth from the ridge surface and from depth. “Dry conditions in unirrigated fields and disruption to the herbicide ‘barrier’ means that the efficacy of pre-emergence chemistry will be compromised. This could well be a year when growers need to think about following up with a post-emergence spray.” He adds that Titus, containing the active ingredient rimsulfuron, is a valuable herbicide which targets key problem weeds and is an invaluable tool in a dry season when pre-emergence activity will be negatively affected.

The Health and Safety Executive for Northern Ireland (HSENI) alongside the Farm Safety Partnership (FSP), has named new farm safety champions and commended the outstanding work on farm safety that has been carried out in the farming community in the last 20 years.

Two of these champions are Malcom Downey, retired principal inspector for the Agri/Food team in HSENI and Harry Sinclair, current chair of the Farm Safety Partnership and former president of the Ulster Farmers’ Union (UFU).

Improving farm safety is the key aim of HSENI’s and the FSP’s work and...
