Ag Economists Release Papers On Herbicide Weed Resistance

According to the International Survey of Herbicide Resistant Weeds, there are 251 species of weeds that have developed a resistance to 161 different types of herbicide. And this is a global problem, with these weeds impacting crops in 66 countries.
 
The escalation of these types of weeds is hurting crop yields, the environment and the bottom line for farmers in the United States and around the world.
 
What has led up to this crisis and what types of policies need to be enacted to stop this problem for farmers moving forward? It's all part of a special edition of Choices Magazine. The theme, entitled "Herbicide Resistance Management" features the following papers:
 
• "Herbicide Use Trends: A Backgrounder" by Craig D. Osteen and Jorge Fernandez-Cornejo 
 
• "Farmers' Perspectives on Management Options for Herbicide-Resistant Weeds" by Raymond Jussaume and Katherine Dentzman

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
