APRIL UPDATE
As we move into April, we are pleased to report that many winter oilseed rape crops have successfully fended off pests and are entering spring with strong growth compared to previous years.
Grass weed control from applications of Kerb Flo or Astrokerb in the autumn worked well giving great control of blackgrass, ryegrass and annual meadow-grass.
The start of spring was slow, which extended the window for Korvetto applications due to the slower growth. We received many reports of late germinating mayweed, cranesbills and cleavers, of which we know Korvetto does a great job to control!
There are some impressive oilseed rape crops out there, showing great potential. However, we did receive reports of pigeon damage, particularly in the south. It was worth waiting in many cases to see the crop recover, particularly after a dose of fertiliser and as temperatures have increased. If the buds and growing point are not affected, the crop normally recovers. Having patience in these cases has paid off.
At Corteva Agriscience, we are dedicated to supporting you throughout the growing season. Our team is here to provide guidance, resources, and innovative solutions to help you achieve a successful harvest. If you have any questions or need assistance, please do not hesitate to reach out to us.
