We have had a very smooth drilling period with little interference from the weather. I wish the same could be said about the chemical applications.
We seem to have had weeks of high winds. The fact that OSR broad-leaved weed sprays have been delayed may have compromised control – particular weeds that may cause concern are cranesbill and poppies. If these weeds are present I am considering the use of Bifenox, but this can only be applied under a Specific Off Label Application (SOLA). I hope the level of control will match last year’s results.
The moisture content of cereal seed-beds varies greatly, depending on location, soil type and cultivations. The present dry weather has reduced the effectiveness of stale seed-beds, with less blackgrass germinating now than in early-drilled rape crops. Failure to reduce blackgrass numbers pre-drilling will create challenges later in the year, so be prepared.
