Integrating Precision Ag Tools for Smarter SCN Assessment and Management

Written collaboratively by Ali Nafchi, John Mueller, Cheryl Reese, Yashar Askarzadeh, Slaman Mirzaee, Karishma Kumari, Ahmed Abdalla, Marisol Quintanilla Tornel, Razieh Yazdani Fazlabadi and Ali Yaghoubi Akbar.

Due to potentially variable egg distribution assessing the density and distribution of SCN in a field is challenging, and relying on soil sampling, but precision agriculture tools may enable more accurate, site-specific monitoring.

Integrating Precision Ag Tools for Smarter SCN Assessment and Management

Should I Spray for Soybean Aphids at the End of August?

Soybean aphid populations are persisting in many soybean fields throughout eastern South Dakota. In many cases, these soybean aphid populations are either at the 250 aphids per plant threshold, or very close.

Monitor Soybean for Soybean Tentiform Leafminer

In 2022, researchers detected soybean tentiform leafminer in McCook, Minnehaha, and Moody counties in South Dakota. The extent of the distribution of this pest in South Dakota is unknown and is currently being investigated.

Soybean Aphids Exceeding Thresholds in Some Parts of South Dakota

There have been a few fields this week that were infested with soybean aphids that are getting closer to threshold. We have also received reports of insecticides being applied to manage soybean aphids in South Dakota.
