Farmers and sprayer operators need to ensure that applications of carbetamide are applied by the latest application date of February 28, advises the Voluntary Initiative (VI).
The current mild and relatively dry weather means there is a short window in which to apply the oilseed rape herbicide carbetamide; the latest date for application is the end of February.
The oilseed rape herbicide propyzamide has passed its latest application date of January 31. The ’Metazachlor Matters’ stewardship campaign recommends that metazachlor and quinmerac should not be applied to winter oilseed rape on drained land after mid-October.
Patrick Goldsworthy of the VI says: “Observing cut-off dates is a legal requirement and will also help protect water and ensure following crop safety.
“Whenever any of these products are applied, it is important to ensure that drains are not running and no heavy rain is forecast in the 48 hours following application.”
