- Identify and Manage Wheat Diseases
- Protect Grain Quality During Harvest
- Plan for Changing Harvest Conditions
1. Prepare Equipment Before Harvest Begins
Before the wheat harvest season begins, producers should ensure that harvesting equipment is properly inspected. Routine maintenance checks to review oil levels, fuel systems, and other components can help keep equipment operating efficiently throughout the harvest. It is also essential to make any necessary repairs on combines or other equipment before the harvest to reduce delays and ensure proper performance.
2. Monitor Weather and Field Conditions
Despite best efforts during the planting season, producers may experience issues during harvest as a result of conditions that may be out of their hands, including the climate. Excess moisture and changing temperatures can severely impact harvest timing and crop quality. A wheat harvest is ideally performed in dry, warm, and sunny conditions. Producers should regularly monitor weather and field conditions to determine the best times to harvest their crops.
3. Identify and Manage Wheat Diseases
Certain weather conditions, specifically excess moisture, can increase the risk of wheat diseases. If not managed, wheat diseases can reduce yield, lower grain quality, and create challenges for future crops, especially when pathogens persist in crop residue, soil, seed, or grassy hosts, which is why early identification is essential.
Before harvesting begins, producers should be aware of the diseases that could harm their wheat – this includes those affecting heads and grains, those affecting leaves, and those affecting the stems and roots. Key wheat diseases to watch out for include:
- Fusarium Head Blight: Characterized by the premature whitening of wheat heads and caused by the fungus Fusarium graminearum. Management may include planting less susceptible varieties, avoiding high-risk residue situations, using foliar fungicides when appropriate, and adjusting combine settings during harvest to help remove lightweight, infected kernels.
- Stagonospora Nodorum Blotch: This disease can affect wheat leaves and heads. Leaf symptoms often appear as brown or tan lesions with a thin yellow halo. Management can include resistant varieties, crop rotation, fungicide seed treatments, and foliar fungicides when appropriate.
- Take-All: This soil-borne fungal disease can cause patches of premature white heads and black discoloration on lower stems and roots. Crop rotation and grassy weed control can help reduce disease pressure.
4. Protect Grain Quality During Harvest
Maintaining grain quality is essential for maximizing yield and ensuring a consistent harvest. Making timely adjustments based on harvest conditions supports a more productive harvest. Producers should take steps to separate damaged grain from healthy crop material to preserve overall quality. Adjusting combine settings based on the specific field conditions can also help reduce grain damage.
5. Plan for Changing Harvest Conditions
Wheat harvest conditions can vary due to weather and crop variability. Producers should be prepared to adjust their strategy accordingly to maintain consistent yields. This includes a proactive approach to moisture changes and field management by adjusting combine settings and recalibrating yield or moisture monitors. The goal of every wheat harvest is to maximize yields while minimizing grain loss.
Key Equipment for Wheat Harvest Season
Selecting the right equipment is crucial for maximizing productivity during a wheat harvest. These machines help ensure consistent grain quality and performance under a variety of field conditions.
