Agronomy for Operators – Part 4 – Spring challenge for grassweed control

With autumn spray strategies left in tatters, it increases the importance of spring applications. Here Syngenta’s experts offer advice on the main problems, timing, techniques, application rates, mixing and sequencing.


The past season’s extremely challenging winter establishment is predicted to have a knock-on effect for spring grass weed control. Implications of weather conditions, crop growth stage and size of the target weeds will all need to be tailored to the season to achieve effective control.

 Syngenta field technical manager, Georgina Wood, warns grass weeds have a huge impact on crop yields and quality. “Maximising control through integrated management techniques is now a key priority, particularly with increasing herbicide resistance issues.”

This season’s delayed drilling, or a switch to spring cropping, offers the opportunity to control emerged grass weeds before drilling, she suggests. But the wet conditions will have also had an impact on cultivations and is likely to have an influence weed germination patterns, as well as crop establishment.
