To assess the crop enhancement effects of Moddus Evo and Amistar Xtra when used in combination. Whilst Moddus Evo is a PGR that is pending registration for anti-lodging and Amistar Xtra is a superior fungicide both these products have been shown to individually contribute to yield increases beyond anti lodging and disease control respectively. In addition trial work has previously shown the combination of these two products to be synergistic with respect to the crop enhancement affect. The aim of this trial was to explore these affects in more detail.

• A strong trend was evident in this trial indicating that the new plant growth regulator Moddus Evo when used in combination with Amistar Xtra gave positive yield results. These results where beyond what could be attributed to antilodging with Moddus Evo and disease control with Amistar Xtra
• The addition of tank mix partners where not seen to be antagonistic to the results and in fact also trended positively however Syngenta recommends not mixing Flexi N or phenxy herbicides with Moddus Evo. The herbicide mix’s greater yields may have been linked to improved weed control.
