Fusarium Head Blight May Appear Quickly in 2020
Late-season Fusarium head blight (scab) infections became a major problem for growers in ND in 2019. The timing of these infections means the disease could make an early appearance in many fields this year, even if the 2020 season is drier. Because Fusarium head blight can appear shortly after any rain event, it’s critical to have the necessary tools on hand to quickly take care of any infection.
Fusarium head blight is a fungal disease that causes bleaching of wheat heads (spikes) and potential discoloration of plant stems. If left alone long enough, pink or salmon spore masses will appear on infected spikes that further spread the pathogen. In its early stages, head scab can be confused with other diseases including black chaff and glume blotch, so pay close attention to plants and look for symptoms unique to head scab.
The disease is important to watch out for due to its potential to severely reduce crop quality and yield, with losses of up to 45% having been recorded. Additionally, head scab produces a deoxynivalenol toxin that, at high levels, can cause your wheat to be priced at a discounted rate or, in extreme cases, refused at the elevator – decreasing your return on investment at the end of the season.
To tackle Fusarium head blight in wheat, we recommend considering Miravis® Ace fungicide, built with Adepidyn® fungicide – the most powerful available SDHI molecule. Miravis Ace can be applied as early as 50% head emergence, giving you the flexibility you need to time your applications right. It also stands up to rain and degradation to provide long-lasting residual protection.
