What is the scouting focus area when checking for Soybean Rust?

When scouting for Soybean Rust, the focus is primarily on low lying or protected areas. This is because Soybean Rust thrives in environments that retain moisture and have less airflow, making these areas more favorable for the disease to develop and spread. Low-lying regions are typically cooler and can trap moisture, creating optimal conditions for the fungus that causes the rust to proliferate.

Other elements, such as high ground with clear airflow, open fields with full sun, and areas with no dew, do not provide the same conducive environment for the development of Soybean Rust. High ground generally has better air circulation, which can help reduce humidity levels. Full sun and areas without dew also contribute to drier conditions that are less supportive of rust pathogens, as these conditions diminish the moisture that fungi like Soybean Rust require to thrive. Thus, the placement of scouting efforts should focus on the more susceptible, low-lying areas where the disease is more likely to occur.
