The area sown to oilseed rape has been largely static in recent years and seems broadly similar this year. Every year seems to bring different challenges which make timely planting difficult and these are mainly weather-related. This autumn, much of the planting was delayed, but relatively mild weather has helped these crops to catch up on canopy production and most are still open enough to enable any further weed control.

Good weed control is important with oilseed rape. Some growers rely on metazachlor-based residuals, either alone or in mixtures such as Katamaran Turbo. Others have stayed with propyzamide products, which were traditionally known as Kerb treatments. While that active is limited in its broad-leaf weed spectrum, it was always good on grass weeds and volunteer cereals.
