Benefits
- +0.35t/ha on average over Aviator (2014 and 2015 n= 44, independent trials)
- Widest effective application window at T2
- Excellent broad-spectrum activity against major diseases in cereal crops
Why Librax?
Why Librax®?
Librax® is an emulsifiable concentrate containing metconazole and fluxapyroxad. Librax® is a flexible alternative providing broad spectrum disease control for use in winter wheat, spring wheat, durum wheat, winter barley, spring barley, rye and triticale. With average higher yield results recorded over Aviator® 235 Xpro in wheat (n= 44 independent trials 2014/15), Librax® is an alternative azole to prothioconazole.
Librax® is highly active against DON generating Fusarium head blight (same rating as prothioconazole) which makes the product an excellent option for high risk milling wheat varieties. In addition, when problems arise with Septoria, the compatibility of Librax® with chlorothalonil boosts Septoria control and resistance management.
Librax® boasts a wide application window at T2 and maintains green leaf area for longer where applications have been delayed. The optimised fomulation of metconazole enables better spreading and uptake for enhanced metconazole performance. Unique physiological benefits of Xemium® lead the crop to utilize 80t less water per tonne of grain and better able to withstand stress scenarios; straw strengthening benefits improve straw quality.
