Research from the U.S. theorizes that more of the nitrogen used by a corn plant comes from the soil, not fertilizer.

Nitrogen use in corn re-examined

Research from the U.S. Midwest sparks controversy, but the solution may be easier

When it comes to nitrogen use in corn, it’s always been a question of how much to apply. University of Illinois research on the source of N – how much a corn plant gets from fertilizer and how much from soil –has initiated a considerable amount of debate since the results were released last May.

Gibberella ear rot was the primary disease causing higher levels of deoxynivalenol in 2023, as it did in 2018.

Mycotoxin situation returns in 2023

The good news is that it wasn’t as bad as other years

Before the planter or drill rolls into a field, there’s hope that rain and sun will be timely and sufficient, that weeds, diseases and insects will be minimal and commodity prices will provide the right finish to the growing season. Then reality sets in. That’s the scenario in most years and 2023 was no different. […] Read more





Tar spot was joined by northern corn leaf blight (shown here) in some Ontario fields, further affecting yields.

Biological control could help reduce tar spot challenges

Recent work studies the impact of Alternaria on impeding disease

Researchers and plant breeders have been working to develop ways to overcome tar spot in corn, but there three primary factors confound the search. For starters, the disease pathogen (Phyllachora maydis) only grows on living tissue. Recreating the ideal conditions under which the disease flourishes (temperatures between 16 C and 23 C and relative humidity […] Read more
