Pre-emergent and early post-emergent products currently provide the main solutions for the control of broad-leaved weeds in Autumn and Winter oilseed rape.
Around 250 advisors and influencers were recently welcomed by the Corteva Agriscience™ DowDuPont team to see for themselves the performance of GF-3447 (proposed name Belkar) a herbicide containing Arylex, in oilseed rape.
The Czech Republic has become the latest country to register Belkar™, the pioneering post-emergence treatment for broad-leaved weeds in Autumn & Winter Oilseed Rape (OSR) Combining Arylex™ active and picloram in a premix formulation, Belkar delivers high efficacy treatment for weeds such as Descurania Sophia, Fumaria officinalis, Geranium pusillum, Papaver and many others.
Danish oilseed rape farmers are taking a closer look at a key innovation in weed control practices. Recent trials have been assessing the use of a post-emergence treatment that could offer a highly effective solution even in well-established crops.
All sorts of cranesbill, whether cut-leaved, dove’s-foot, small-flowered or round-leafed, make life difficult for rape growers in many areas.
Danish farmers are already enjoying the benefits of Belkar™, this revolutionary new herbicide for the post-emergence treatment of broad-leaved weeds in winter oilseed rape.
Head of Agroecology and Biometeorology at the Czech University of Life Sciences Prague, Professor Josef Soukup also runs the institute that conducts plant protection products registration trials for various companies. He has always been interested in oilseed rape (OSR) and here he outlines its importance in the Czech Republic and the how farmers manage weed control.
In France and Belgium yields have been excellent. The UK saw mixed results, whilst Germany had disappointing yields and the Czech Republic experienced a fall. Over the whole of the EU there were middling yields of OSR in 2017, at 3.27 t/ha, but there were huge disparities between countries and even regions.
Alongside wheat and barley, oilseed rape (OSR) is one of the three main crops grown in Berry and on many farms it is the most important. Weeding is challenging, particularly where plots are infested with Cranesbills and grasses as well as cornflowers, poppies, umbellifers and milk thistles.
To improve weed control, farmer Jean-Hilaire Renaudat would like to have access to broad-spectrum post-emergence solutions for broadleaved weeds.
Originally found only in the south of France, milk thistle (Silybum marianum) has been heading steadily north for some years now, particularly into the Central region where it has become a major problem.
Dow AgroSciences is currently developing a wide spectrum broad-leaf weed herbicide for use in the autumn and a unique broad-leaf weed herbicide for the spring.
Frédéric Lievens, Marketing manager for Oilseed rape Herbicides at Dow AgroSciences, France talks about the impact of post-emergent treatments for OSR weed control.
Danish farmers are celebrating receipt of the first batch of Belkar™, the innovative new herbicide for the post-emergence treatment of broad-leaved weeds in winter oilseed rape.
Denmark becomes the first country in the world to register Belkar™, the breakthrough herbicide for the post-emergence treatment of broad-leaved weeds in winter oilseed rape.
Post-emergence treatment would lighten the workload and crucially would allow treatment when weeds are visible, thereby giving better opportunities for choosing the best herbicide and dose for the weed flora present, thus optimising the use of herbicides.
Viewed as a revolutionary solution to the problem of broad-leaved weeds, Arylex™ active is set to be the latest innovation to the wide-ranging Dow AgroSciences OSR herbicide portfolio.
