Corn planting was later than normal and later than last year because of usually wet conditions across most of the state. The unusual fluctuations in air temperatures and soil temperatures further impact corn germination and emergence as well as seedling vigor and thus impact the amount of seed decay, seedling blight and crown rot which may occur.
Across the state of Iowa, much of the crop is reaching V5 to V6 and thoughts of an early fungicide application have probably crossed some people’s minds. Every year, we evaluate and compare registered fungicides applied at either V5 to V6, R1 alone, or At V5 to V6 plus R1 for foliar disease management and effects on yield.
With much of Ohio corn now planted statewide, growers who can identify any emergence problem early on will likely have a better chance of coming up with a successful solution to the issue, said an agronomist in the College of Food, Agricultural, and Environmental Sciences at The Ohio State University.
Grain industry representatives are touting the effectiveness of the One Sample Strategy, a standardized testing method for aflatoxin. The program is administered by the Office of the Texas State Chemist, part of Texas A&M AgriLife Research.
A website developed by plant pathologists from Purdue University and a nationwide partnership of research institutions could help farmers better understand and respond to the threat of mycotoxins and ear rots in corn.

Twelve corn varieties and inbred lines [BP1] showing resistance to ear rot caused by the fungal pathogen Fusarium have been identified from the screening of 43 white corn lines/populations and Lagkitan in a study conducted by the University of the Philippines Los Baños (UPLB).
Although experts are forecasting a record-plus year for yields, an abundant harvest does not always indicate a problem-free crop to feed to livestock. Preliminary data conducted by Alltech’s 37+ Mycotoxin Analysis Program is now showing there might be more than meets the eye in the fields.
