Fusarium and other diseases can threaten your crops’ health and put your maximum profit potential at risk. With the right insight and understanding, you can fight back and keep the risk under control. Disease development in field crops is dependent on three important factors.
Understanding the Threat
Once a pathogen infects the crop, it robs nutrients and energy from the plants, which reduces the photosynthetic ability of the plant. This can reduce yield and downgrade grain quality. The Canadian National Millers Association estimates that annual profit damage from Fusarium often causes losses of more than $1B in Western Canada. Fungicides can offer effective protection against crop diseases, and increase yield, grain quality and profitability.
The Right Timing
The timing of a fungicide application for disease control is critical when used as a preventative measure. Knowing when to scout fields is important for identifying what diseases are present and what stage of the crop is best for fungicide application. These are some of the common fungicide application timings for crops in Western Canada.
Canola: 20 to 50% flowering stage.
Pulses: Prior to disease development up to the onset of flowering.
Cereal Foliar Diseases: After flag leaf emergence. The use of a fungicide at this timing is intended to keep the flag leaf free of disease for maximum yield. In wheat, oats and rye, the flag leaf contributes over 50% of the yield. In barley, the flag and the penultimate leaf contribute over 50% of yield.
Fusarium Head Blight Timing in Wheat: When 75% of wheat heads are already emerged and 50% of heads on the main stem are flowering. See labels for crop timings, disease listings and rates.
Using field scouting to identify diseases and selecting the optimal fungicide application timing is challenging because disease symptoms can be difficult to distinguish from other stresses.
