Download PDF Could blackgrass in oilseed rape be managed differently to reduce the losses of propyzamide to water? Some work being conducted by Stephen Moss on behalf of water companies seems to suggest it’s possible. CPM finds out more. The majority of detections (65%) were after 1 February and 10% were over the 0.1ug/l limit. By Lucy de la Pasture As autumn gradually creeps towards winter, oilseed rape growers will be keeping a keen eye on the temperature and ground conditions to catch the optimum window for propyzamide application. The stalwart OSR herbicide takes the last curtain call before the spring, with a tricky spot in terms of timing. The soil temperature ideally needs to be 10⁰C at a depth of 30cm, which typically occurs around 10 November when field conditions can be more difficult to travel. But growers are being asked to consider drinking water supplies when propyzamide is applied because it’s one of the pesticides of most concern to the water companies, explains Rebecca Carter of Anglian Water. “When present in high amounts, propyzamide can overwhelm the water treatment work processes. Although propyzamide can be partially removed using conventional treatment processes, unlike metaldehyde, peaks in levels cause operational…
