If you use AstroKerb or Kerb Flo 500 when the traffic light is on red, soil temperatures may be too high, propyzamide will breakdowna 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.
