Launch early post-em attack on grassweeds

摘要

Concern is growing over grassweed levels in winter wheat and growers are advised to get post-emergence herbicide treatments on early.This autumn was hailed as the best opportunity to get on top of blackgrass in seven years, with the hot dry summer resulting in low weed seed dormancy.This led to fast germination of blackgrass prior to drilling, presenting the chance of good out-of-crop control, taking pressure off herbicides chemistry.With last autumn's troubles in mind, Agrovista technical manager Mark Hemmant says many growers still drilled early, without maximising stale seed-beds."As a result those early drilled crops have really suffered. Pre-emergence herbicide performance has also been poor in the dry conditions," he adds.
