Metribuzin can now be safely applied as a pre-emergence herbicide to Elland potatoes, extending the usage for ADAMA’s product Shotput.
Additional trials in other varieties are currently ongoing, with initial results being promising according to the company.
“ADAMA UK has spent several years testing a collection of newer potato varieties for metribuzin selection,” explained Dr Bill Lankford, ADAMA’s herbicides technical specialist.
“As a result, several new varieties have been added to the list of those to which Shotput can be applied at the pre-emergence timing, with Elland (an early maincrop variety from Cygnet PB) the latest to be added.”
The varieties Baby Lou, Georgina, King Russet, Lucera, Soraya, Tyson, Edison and Babylon were also tested in 2023, and have so far been shown to have no commercially unacceptable symptoms from Shotput.
“At present, the latter results are provisional, with more trials scheduled to take in due course to validate the findings,” Dr Lankford added. “So far, the results look very promising, and we are confident that Shotput will soon be approved for growers to use on a wider range of varieties. We look forward to publishing an updated list of Shotput-approved varieties once the necessary testing regime has been concluded.”
