The Kerb Weather Data (KWD) tool is meant to be used as a guide to local weather conditions to aid growers and advisors in making local tactical decisions to optimise their AstroKerb® and Kerb® Flo applications and thus their activity against blackgrass.
Kerb Weather Data (KWD) is available on the link below from mid-October each year.
Click hereIf you use AstroKerb or Kerb Flo 500 when the traffic light is on red, soil temperatures may be too high, propyzamide will breakdown quickly and blackgrass control may be compromised. In forward crops, large canopies may be closing in rows before the KWD tool indicates green for go. Corteva Agriscience™ trials over many years have shown blackgrass control from propyzamide is not impeded by large crop canopies. Always adhere to stewardship guidelines especially with respect to water, to help ensure we keep essential active ingredients in our armoury to help grow our crops.
For Kerb Weather Data information at your fingertips, download the Corteva Arable App, and use the Kerb Flo and AstroKerb timing tool for up to date application information for your postcode. Agronomists can also check postcode information for all their farmer clients too. The Corteva Arable app is available for iOS and Android devices.
