Getting rid of broad-leaved perennial weeds like docks will increase grass silage yields and improve its quality, allowing cows to produce more milk from forage, and less from expensive bought-in concentrates, which is helpful in times of lowered milk prices.
“Research shows that a 10% population of docks in a sward results in 10% loss of grass growth, reducing the amount left to cut or graze,” explains Brent Gibbon, grassland agronomy manager for Dow AgroSciences.
“Where docks are present, weed control is a small cost relative to the gain in extra grass and silage produced.”
Forty years ago sugar beet growers could use Dow Shield (clopyralid) for the very first time to control thistles. Further investment saw volunteer potatoes added to the label in 1991. And growers today are still able to use this effective herbicide.
After the registration of Pixxaro EC™ in Denmark in February, a second product containing the breakthrough ingredient Arylex™Active has been registered in Denmark. Zypar, which also contains Florasulam, has been approved for the control of broad-leaved weeds in winter- wheat, rye and triticale and in spring- barley and wheat.
Brome grasses are some of the most competitive grassweed species. There are five main species of brome which frequently occur as weeds of arable crops in the UK; however it can be difficult to tell apart the different species. Knowing which species of brome you have is important, as cultural control options vary between species.
This detailed leaflet on identification of bromes was produced by Dr Stephen Moss and Rothamsted Research, and sponsored by Dow AgroSciences.

What does this mean for Dow AgroSciences products, Dursban WG and Equity, which contain chlorpyrifos-ethyl?
