Arylex™ active – ‘A European perspective’
Last month, Global Project Leader, Francois Lucas offered us an insight into the development of Arylex™ active. Now he gives us a European perspective highlighting the flexibility of Arylex across different climates, resistant weeds and spray windows.
‘The European region is relatively diverse’ says Francois. ‘In terms of the range of target weeds, the type of cereal crops, timing of application, climate and farm size, we see a wide variety of conditions and requirements. This variation in the needs of farmers between larger farms where high productivity is key and smaller farms where ease of use is paramount, has led to the development of Arylex products with alternative formulations.
Francois tells us ‘ For example, Pixxaro™ combines two of our (Dow Agrosciences) proprietary ingredients– fluroxypyr and Arylex. Pixxaro is useful in offering post-emergence control of many of the more troublesome broad-leaf weeds particularly cleaver and chickweed. Zypar™ however is a wide spectrum broad-leaf herbicide for winter and spring cereals which combines two active ingredients, Arylex and and florasulam’.
One of the most challenging issues facing farmers across the EU region is the proliferation of ALS resistant weeds. Francois suggests that the subject of ‘resistant weeds’ deserves more consideration. ‘When we think about resistant weeds we need to consider both the short and the longer term. Today it’s all about the localiased targeting of some weeds such as Papaver, Matricaria and Stellaria. Looking forward however, we need to anticipate future issues and to implement the appropriate R and D programmes to ensure that we avoid difficult situations such as the one we’ve found ourselves in now with resistant grasses . That’s why we have high hopes for Arylex as we anticipate that Arylex products will help prevent the future proliferation of resistant broad-leaved weeds across the whole of the EU region’.
Flexibility is a key attribute of Arylex, a point further demonstrated when Francois talks about crop types. ‘We see great potential in the application of Arylex on most cereal crops such as winter and spring wheat and barley.’ To use it most effectively he suggests its application as early as possible. ‘Whilst it’s always better to target control as early as possible in order to limit competition between weeds and crops, Arylex offers a really wide spray window, from growth stages 12 right through to stage 45’.
The outlook for Arylex continues to be bright. Since the first part of this interview was published the UK has followed Denmark in registering Pixxaro™ EC and more registrations in more countries are expected in the coming months.
