DowAgroSciences says that CRD has granted an approvalfor AstroKerb to allow the straw from oilseed rape crops treated with AstroKerbto be burnt for heat or electricity production. The following updated statementwill now appear on the label : DO NOT remove oilseed rape straw from the fieldunless it is to be used for burning for heat or electricity production.
Thisnew approval makes AstroKerb even more flexible to use in any autumn oilseedrape weed control programme. Last season, before this label update, straw couldnot be baled or removed from the field at harvest. But now growers have theoption to remove straw from an AstroKerb-treated field, provided that straw isgoing to be burnt for heat or electricity generation, says Alex Nichols of DowAgroSciences.
Heexplains that, since AstroKerb will retain the same MAPP number, the new approvalwill cover current stocks of the product. This means that straw from this autumns rape crop that receives anAstroKerb application, even if the updated statement is not actually on the label,can still be used for burning for heat or electricity generation. A revisedlabel will be available from the Dow AgroSciences website from early November, shouldgrowers or advisors want to check any details.
Followingthe successful launch of AstroKerb last autumn, oilseed rape growers have beencommenting on the high level of black-grass, poppy and mayweed control achieved. AstroKerb contains the well-knownresidual active ingredient propyzamide, which controls black-grass, a number ofother grass-weeds and broad-leaved weeds, together with a low dose of thecontact-acting aminopyralid that adds to the broad-leaved weed spectrum. As aco-form, this product controls most of the difficult weeds in winter oilseedrape, says Alex.
