Vegetable, allium and nursery crop growers have suffered in the last few years through the loss of crop protection actives, either as more products are revoked or go through re-registration and lose crops and uses. One manufacturer however has been busy adding to their recommendations and supporting and encouraging Extension of Authorisation for Minor Uses (EAMU’s) for their chemistry. “We receive a lot of queries from growers on our Hotline about what they can use on their vegetables and onion crops. One of our classic active ingredients clopyralid that has been on the market for 40 years this year continues to be an important herbicide for these specialist growers and each year additional crops are added or recommendations altered to make them even better,” says Dilwyn Harris, Principal Biologist for Dow AgroSciences.
“Having been available for 4 decades doesn’t mean that there have been no improvements on its journey. In that time all registration hurdles have been exceeded and four years ago Dow invested in and launched a new and improved double strength Dow Shield 400 formulation.
Maximising timeliness of applications of both graminicides & fungicides is paramount. Broadway Star or Unite offer market-leading control for brome, ryegrass & wild oats, plus robust blackgrass control in the case of Unite, they do so whilst offering you the greatest flexibility to tank mix fungicides (including chlorothalonil) with this application to best control early diseases.
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.
