New research by NIAB is set to help growers and agronomists make more effective decisions on spring grassweed herbicide application timing and treatments. The trials, in partnership with Syngenta, will assess the competitiveness and risk of seed return from a range of key grass weeds, according to germination timing. Syngenta grass weeds specialist, Georgina Young, says that growers and agronomists typically face the dilemma of making an early Axial Pro (pinoxaden) herbicide application to tackle overwintered weeds before they become too large and difficult to control, or delaying treatment to allow more weeds to germinate and emerge in the spring. “Now we have pioneering research that will help to quantify just what impact the more aggressive overwintered weeds are having on the crop and how many seeds they are likely to produce, along with the consequence of later spring emerging weeds for crop competition and seed return,” she explains. “That will enable more informed decisions on appropriate spring Axial Pro herbicide timing for different grass weeds, along with helping to calculate the most cost-effective options for herbicide rates required on different sized weed populations.” Controlled conditions The work is looking to assess the competitiveness and seed return viability of blackgrass,…
