Reactive herbicide applications advised as OSR area set to increase

With the oilseed rape area expected to increase this autumn, Corteva Agriscience is advising farmers to consider a reactive approach to weed control in order to reduce risks during crop establishment. Charlotte Cunningham reports. Buoyant prices for the 2021 crop are being underpinned by demand from processors and it’s likely that significantly more OSR will be drilled this August and September compared to the same period last year. Early predictions are that the c 280,000ha of crop being harvested now will be comfortably exceeded. But with the unpredictable nature of the weather, and the threat of pest damage still present, Corteva is urging farmers to consider strategies which minimise risk. “Research has helped improve knowledge around how to successfully establish a resilient crop, and new thinking has developed in the face of pest and weather challenges seen in recent years,” says John Sellars, OSR herbicides manager. “But OSR growers will still be determined to minimise risk as much as possible, driven by variety choice, drilling dates, targeting soil moisture and an effective herbicide programme.” One tactic which has proven extremely effective in the UK over the past two seasons is to switch away from a broadacre pre-emergence approach to weed…
