The AHDB has today announced its success in securing emergency authorisation of a desiccant to protect the quality and yield of linseed seed crops this harvest. Charlotte Cunningham reports. Spotlight Plus (carfentrazone-ethyl) received the authorisation following the withdrawal of diquat, which would have left seed producers with no chemical option for desiccation. Although the original application also requested use on main crop linseed, the availability of a chemical alternative (glyphosate) failed to see use in this situation granted. Bolette Palle Neve, who manages emergency use authorisation applications at AHDB, said: “In linseed, the seed tends to ripen before the stems fully dry out, which can make the crop a challenge to cut. The UK weather is also not consistent enough for crops to be swathed and left to dry naturally, so chemical desiccation is an essential option.” Although available for the main crop, the use of glyphosate in the seed crop is not permitted because it can affect germination and plant survival. Hannah Foxall, an agronomist for Premium Crops, which worked with AHDB to secure the authorisation, said: “The authorisation for seed crops was particularly critical. The longer linseed remains in the field, the more vulnerable it becomes to several…
