2025 GLEXPO Pesticide Applicator Review and MDARD Testing offered in English and Spanish, December 11

By Safa Alzohairy

The Michigan State University (MSU) Pesticide Safety Education Program (PSEP), Michigan State University Extension and the Michigan Department of Agriculture and Rural Development (MDARD) are pleased to announce that the pesticide safety classes will be held at this year’s Great Lakes Fruit, Vegetable & Farm Market Expo in both English and Spanish on Dec. 11, 2025. The event will feature a full day (8:30 a.m. – 3 p.m.) of educational sessions tailored to pesticide applicators.  

Morning session: 8:30 a.m. to 12:30 p.m. Check-in is 8 to 8:30 a.m.  

The morning session is a 4-hour review covering all chapters of the National Pesticide Applicators Certification Core Manual. It is designed to provide applicators with guidance on proper techniques for mixing, loading and applying pesticides safely. Two parallel sessions will be offered, one in English and one in Spanish. This training will prepare participants for the MDARD restricted use pesticide (RUP) test, which will be administered in the afternoon. The morning session is mandatory for those planning to take the test.  

We recommend participants read and study the Core Manual before attending the review. Copies may be ordered from: msupesticidemanuals.com. County Extension may also have copies available. Visit MSU Extension's website to locate the county Extension office nearest to you. Please call ahead for availability.  

Recertification opportunity  

Attendees holding Commercial Certified Applicator or Private Certified Applicator certifications can earn four RUP credits by attending the morning session, allowing them to recertify through credits.

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
