AdvertisementAlternative CropsWeed control in wet fields can wait until spring, says Extension scientistMissouri With a wet fall nearing its end, many farmers won't be able to get into fields for weed control this season. That might not be a bad thing, said Kevin Bradley, University of Missouri Extension weed scientist. Rain makes big crop difficult to harvestSIOUX FALLS, S.D. (AP)--Record and near-record corn and soybean crops sit in area fields tantalizing farmers, but there is one problem: In many places, it's been too wet to get at them. A cool, damp summer delayed the growing season. Then, in the past month, as farmers prepared to harvest crops still laden with moisture, seemingly interminable rain made a bad situation worse. From robotics to climate change, annual meeting tackles new angles on weed controlCan the same robotic technologies used in manufacturing, mining and even warfare play a role in weed control? Is climate change fueling a new generation of aggressive weeds and making it tougher to manage them? These are two of the many thought-provoking topics to be explored during an upcoming joint annual meeting of the Weed Science Society of America and the Society for Range Management. Farmers should test corn for high mold levelsMissouri Not testing this year's corn crop could be risky for hog farmers. This fall's wet weather has spurred mold growth, which can lead to toxin buildup in feed, said University of Missouri Extension specialists. Will soybeans turn yellow?By Richard C.

Late wheat planting requires extra planning
Kansas Some wheat has not yet been planted this year across Kansas--especially in the eastern third of the state--due in some cases to wet soil conditions. In other cases, producers are still waiting to harvest their soybeans, grain sorghum or corn before planting wheat, said Jim Shroyer, Kansas State University Research and Extension crop production specialist.[Read More] Spying on corn rootworm predators' nightlife Agricultural Research Service entomologist Jonathan G. Lundgren, while exploring corn fields at night, has found a very different group of predators than the ones that feed during the day. It turns out that these night-time predators have a great appetite for corn rootworms, the most costly pest of corn in the world. Research on day-active and night-active predatory insects is important for scientists who are developing strategies that maximize ...[Read More] Scientists plot genetic ploy against grain pest Aided by a genomic map of the red flour beetle, Tribolium castaneum, Agricultural Research Service and university scientists are plotting a kind of genetic sabotage on the pest's basic life functions--from locomotion to digestion. Nationally, infestations of flour beetles and their beetle cousins cost millions of dollars in losses annually to stored grains and the food products made from those grains. Warehouse sanitation usually keeps beetle ...[Read More] Crops and weeds: Global climate change's first responders A team of Agricultural Research Service plant physiologists is studying how global climate change could affect food crop production--and prompt the evolution of even more resilient weeds. Lewis Ziska, Richard Sicher and Jim Bunce all work at the ARS Crops Systems and Global Change Laboratory in Beltsville, Md. Over the past several years, the three scientists have conducted research on a range of food crops--including soybean, rice, ...[Read More] Scientists find ozone levels already affecting soybean yields Current atmospheric ozone levels are already suppressing soybean yields, according to Agricultural Research Service scientists and university cooperators studying the effect of global climate change on crops. ARS plant physiologists Don Ort and Carl Bernacchi, molecular biologist Lisa Ainsworth, and geneticist Randall Nelson have been working with University of Illinois scientists on a project called "SoyFACE"--short for Soybean ...[Read More]
