Farmers faced with tight profit margins may consider cutting back on weed control efforts this growing season, but an Iowa State University agronomist said doing so may cost farmers money in the long term.
A University of Wyoming weed scientist—frustrated with the noise surrounding genetically modified organisms and glyphosate use—analyzed data to see for himself if biotech adoption has had a negative or positive effect ...
Plant biologists at The University of Western Australia have revealed the relationship between plants and the parasite that causes malaria is close enough to mean many antimalarial drugs are effective herbicides.
Herbicide-resistant "superweeds" change their mating strategies over time, an evolutionary shift that helps them hold onto valuable genes and outcompete other plants, according to a new study from University of Michigan researchers.
According to new research from University of Virginia economist Federico Ciliberto, widespread adoption of genetically modified crops has decreased the use of insecticides, but increased the use of weed-killing herbicides ...
University of Montana researchers are giving the public its first look at the widespread use of herbicides on federal and tribal land in North America, and they urge land managers to better document it.
Twenty-five years ago, waterhemp was virtually unknown to Illinois farmers. Today, the broadleaf weed blankets corn and soybean fields across the state and the Midwest, causing yield losses from 40 to 70 percent.
Herbicide-resistant weeds are becoming increasingly common in agricultural landscapes. Existing methods for confirming herbicide resistance require knowledge of the genes responsible for target-site resistance, but this information ...
Some herbicides are more effective when applied at noon compared to early morning or late evening applications, according to data from the University of Tennessee Institute of Agriculture.
Scientists at the John Innes Centre have discovered a new target in plants for the development of new herbicides for use by farmers and gardeners.
