GRASSLAND WEED CONTROL Grassland weed control is becoming more challenging with the reduction in approved active ingredients and contamination of watercourses. This chart will help you to identify appropriate options available to you.

EXAMPLE PRODUCT OPTION WEED TARGET GRASSLAND AGRONOMY Grass is one of the most flexible crops on the farm and can provide economically favourable feed throughout the year. Whether it is cut or grazed, when well-managed, grassland can provide a crucial and cost effective contribution to dairy or meat production. Agrii can facilitate you in growing the best grass possible and through the use of appropriate weed management, disease and pest control we can ensure your yield, quality and utilisation is optimised. There is over 7,000 ha of rotational and permanent grassland in the UK. GRASSLAND PEST CONTROL With Chlorpyrifos no longer available for use on grassland, even greater attention should be paid to cultural control of pests such as Frit Fly and Leatherjackets. Following previous grass crops both can cause problems to new leys, but Leatherjackets in particular can be devastating. For guidance on how to use cultural control methods to the best advantage on your farm please speak to your Agrii agronomist. Frit fly Leatherjacket Crop protection: Grassland RAGWORT CONTROL IN GRASSLAND Ragwort is often found in grassland and is poisonous to livestock. Additionally it is an ‘injurious weed’ and those who permit it to grow unchecked on their land are liable to prosecution. New guidance on ragwort control in grassland was issued in 2016 and this can be found in the Code of Practice on How to Prevent the Spread of Ragwort. Ragwort control is limited and the weed is notoriously slow to die after treatment. For this reason silage cannot be cut less than a month after spraying without risking contamination by dying, but still poisonous plants, and livestock must be kept out of treated fields until any ragwort has completely recovered or died and there is no visible sign of the dead weed. Unfortunately ragwort plants sprayed with herbicide are more palatable and contain higher levels of toxins than those untreated and therefore pose a greater risk to livestock. Timing for control can be in either autumn (usually best for fields likely to be cut) or spring (for fields likely to be grazed). For information on products and further guidance please contact us.
