The benefits of a tactical approach to grassweed control, including ploughing, crop rotation and a full herbicide programme are being clearly demonstrated in a Dow AgroSciences rotational grassweed trial in Warwickshire.
The trial, now in its fourth year, assesses the difference that rotating cultivation practices and crops, along with herbicide programmes makes to blackgrass, ryegrass and brome control in winter wheat and oilseed rape (OSR).
With the current season, one of the worst ever for blackgrass infestations, growers should be planning to take advantage of every option available to bring this and other grassweeds under control in autumn 2014, says Dow AgroSciences Stuart Jackson.
Harvest 2013 saw above average blackgrass populations after appalling winter conditions. However, early drilling into dry conditions in autumn 2013 saw herbicides run out of steam, whilst later sown crops did not receive full herbicide programmes.
Weed experts at Dow AgroSciences have published a new guide to help horse-riders and equestrian business owners get rid of problem weeds in their paddocks.
Species such as docks, nettles, buttercups and ragwort can often be seen where horses graze. If left alone, they will eventually take over the whole field and are usually a sign of worn-out or damaged pasture that has been overgrazed.
Spray docks for long-term control – don’t top them.
Docks, nettles and thistles are prolific in grass fields this year after the mild winter and early spring, with strong perennial weed growth since March.
“A shortened spray window last year, due to the late start to the season left many grass fields untreated,” explains David Roberts, grassland agronomist with Dow AgroSciences. “And the wet winter has also encouraged weed seeds to germinate in poached areas where soil was exposed.
