Timing post-emergence herbicides in corn

Properly timing the application of post-emergence herbicides is critical, says Aaron Hager, University of Illinois Extension weed specialist. Recent precipitation, coupled with warm temperatures, will result in rapid growth of emerged weeds and possible reductions in corn yield if weeds persist too long.

“Unfortunately, it’s not possible to accurately predict the specific day after planting or emergence when weed interference begins to reduce corn yield,” Hager says. “This interval is influenced by many factors, and can vary based upon the weed spectrum, density of certain species, available soil moisture, etc.” Read more ...

European Labs search for new weed control

Walker Jones a USDA entomologist, along with European Biological Control Lab (EBCL) in France and Beneki Phytopathological Institute in Greece, are now seeking out a method of controlling the perennial weed Silverleaf nightshade (Solanum elaeagnifolium). By looking at insects, mites and nematodes that could be used in a biological based approach to controlling this invasive weed.

Silverleaf nightshade from the Americas has spread to Southern Europe, Africa, India, Australia and other parts of the world. Its being targeted for its ability to out-complete native plants, reduce crop yields and diminish pasture productivity. Also its orange berries can poison livestock. Read more...
