By: Philip Cosgrave

When getting the sprayer out to control grassland weeds on autumn reseeds, there is an opportunity to add a foliar fertiliser to improve weed control and ensure long term sucess of the new ley.

The effectiveness of herbicides on autumn reseeds can be improved if a foliar fertiliser is tank mixed with the herbicide. The foliar fertiliser works by stimulating the weeds to grow more actively, which results in more of the active ingredient being taken up by the weeds.

Spraying reseeds with herbicide can knock the young grass plant back, especially in late autumn when growing conditions are not ideal. The use of a foliar fertiliser with the herbicide helps the grass plant cope better with the stress of being sprayed. Grass which is supplied with a full complement of nutrients at the onset of an environmental stress is more resilient. The improved growth of grass seedlings will help fill in bear patches, reducing light and space for any new germinating weeds.

Applying a foliar fertiliser with the herbicide can significantly improve the recovery of the sward. By giving the grass close to the weeds a boost it will help the grass out-compete the weeds and quickly recover any bare patches to avoid these being recolonised by newly germinating weed seedlings.

YaraVita Croplift Pro is ideal for this application; containing a readily available source of nitrate nitrogen to give the grass a boost together with phosphate, potash and a full range of micronutrients. Yara recommend YaraVita Croplift Pro at a rate of 2.5 kg/ha or 1 kg/acre in conjunction with your grass herbicide. It contains a full complement of nutrients to ensure the long-term success of your new ley

YaraVita Croplift Pro can be tank mixed with almost all common grassland herbicides, if in doubt ask your supplier about compatibility.
