Media Advisory: CFAES Experts Can Address Climate Change Report

 
Experts from the College of Food, Agricultural, and Environmental Sciences are available to discuss with the media the effects of climate change on the environment in light of the recently released national climate report.
 
The Fourth National Climate Assessment, which the White House released Nov. 23, states Earth’s climate is “changing faster than at any point in the history of modern civilization” and that the primary cause is human activity.
 
For agriculture, the impact of rising temperatures is significant, according to the report.
 
“Increases in temperatures during the growing season in the Midwest are projected to be the largest contributing factor to declines in the productivity of U.S. agriculture,” the report states.
 
Climate change will continue to affect the health of livestock, crop yields and quality, and the economy of rural communities, according to the report.
 
It also states that “rising temperatures, extreme heat, drought, wildfire on rangelands, and heavy downpours are expected to increasingly disrupt agricultural productivity in the United States.”

Accuracy in testing for DON

Video: Accuracy in testing for DON

Deoxynivalenol (DON) is a mycotoxin naturally produced by the fungus that causes Gibberella ear rot in corn. Infection occurs through the corn silk channel when ideal temperatures (approx. 27°C) and higher humidity are present. Cool wet conditions after pollination favour continual disease development and determines the level of infection. Effective sampling, detection, and quantification of DON are challenging due to its uneven distribution on the ear as well as its presence across the field, resulting in infected and non-infected kernels in the same grain sample.
