Controlling thistles in grassland

Fields filled with 10% thistles produce 10% less grass to feed to livestock says Corteva Agriscience’s weed biology specialist Dr Nicola Perry.

“As early grass growth has been poor in many parts, forage supply might not meet demand coming from the cattle and sheep grazing it. Spraying thistles with an effective translocated herbicide specifically designed to kill the roots will help optimise grass growth from now on.”

The two most common and damaging thistles in the UK and Ireland are creeping thistle and spear thistle, which both compete with grass for space, light, nutrients and water. They reduce the amount of grazing available and are unpalatable to stock. In sheep flocks, they can lead to a greater incidence of orf, a viral skin disease spread through open wounds from ewes and lambs pricked by the thistles.

“Spraying with Thistlex at a rate of one litre/ha in 200-400 litres of water will give outstanding control of creeping and spear thistles, as well as other weeds such as common nettle, fat hen and mayweed,” Dr Perry adds. “The herbicide gets right down into their large vertical and horizontal root systems.

In mid-summer it may pay to top well-grown thistle plants and spray the active re-growth two to three weeks later.

“Animals must be taken out of the field when it is sprayed, but can return seven days after treatment, as long as there is no foliage of poisonous weeds such as ragwort present.”

Five nature-recovery projects spanning nearly 100,000ha across the West Midlands, Cambridgeshire, the Peak District, Norfolk and Somerset have been announced by the government and Natural England today (Thursday, May 26).

This is the equivalent in size to all 219 current National Reserves.

The aim of the projects is to deliver nature recovery at a landscape scale, helping to tackle biodiversity loss, climate change and improve public health and well-being.

All five projects will make a significant contribution towards the national delivery of the international commitment to protect at least 30% of land and...
