Grazon® Extra Plantback Trial 2021

This trial was set-up from April 2021 to apply eight herbicide treatments at 4, 2, 1 and 0.5 months before planting ten different forage species to determine the safe plantback period. With above average rainfall during 2021, breakdown of herbicides was quicker than normal.

The aerial footage below (taken on 07th October 2021) shows the treatments from rep 3 and 4, which were applied two weeks before planting the forage species on 10th August 2021.

Clear trends – all broadleaf herbicides showed effects on all species when applied two weeks before planting, even though this is difficult to judge from the photo. Please navigate the aerial photo below and hover over the treatments to see some of the effects.
