The herbicide Zypar™ with the new active ingredient Arylex™ as tankmix partner for graminicides for spring application in cereals

Spring applied graminicides often show an insufficient efficacy against dicotyledonous weeds. Therefore tankmix partners are used to gain more control against these weeds. Development trials were conducted in Germany, France and the United Kingdom from 2014 to 2017 to test the biological compatibility of Zypar™ herbicide and different graminicides against Alopecurus myosuroides (ALOMY), Apera spica-venti (APESV) and Bromus sterilis (BROST). The herbicide Zypar™ provides a broad efficacy against dicotyledonous weeds and because of its auxinic like active ingredient and its OD-formulation it also proved to be an ideal tankmix partner for graminicides. In addition, the adjuvant (MSO-Type) incorporated in Zypar™ increases the efficacy against broadleaf weeds and grasses. No antagonisms between Zypar™ and graminicides were observed in the field trials. In some cases the mixture of Zypar™ and a graminicide even provided a higher efficacy against grasses compared to the graminicide applied alone. The safener Cloquintocet-Mexyl which is incorporated in the formulation of Zypar™ enhances the metabolisation of Arylex™ active in the crop. In some cases the selectivity of graminicides could be significantly improved by the addition of Zypar™ even when liquid ammonium urea fertilizer was added to those mixtures.
