Though planting crops more densely can be an effective approach for suppressing weeds in problem areas, many growers fail to adopt this approach because of the high cost of seed. New research featured in the journal Weed Science, though, describes a bioeconomic model growers can use to overcome that cost barrier.
Researchers from the University of Missouri recently conducted two field studies to explore the effectiveness of electricity in weed control. They used a tractor attachment called The Weed Zapper™ to electrocute eight types of weeds common in soybean crops, including herbicide-resistant waterhemp.
Horseweed is one of the most common and troublesome weeds in soybeans – able to cause significant yield losses when left uncontrolled. That’s not surprising when you consider a single horseweed plant can produce up to 200,000 feather-light seeds that can be easily spread across vast distances.
The gap between potential and actual soybean yield achieved by farmers in the Southern Africa region is high due to limited investments in inputs, poor agronomic management practices and lack of quality seeds for improved varieties.
Complaints about off-target movement of dicamba, 2,4-D and other synthetic auxin herbicides persist, despite the introduction of reduced-volatility formulations. One indicator: a survey shows that 30 percent of Nebraska growers believe injury to susceptible soybean crops is caused by off-target movement of dicamba applied to corn.…
Harvest-time weed seed controls have proven highly effective at reducing herbicide-resistant weeds in Australian cropping systems. One of the most popular tactics is the use of an impact mill that intercepts chaff as it exits the harvester.…
Corn and soybean growers in Nebraska are now facing their worst nightmare. A research study featured in the journal Weed Science shows a population of waterhemp has evolved resistance to four distinct herbicide sites of action – including PPO inhibitors, ALS inhibitors, EPSPS inhibitors and PS II inhibitors.…

More and more research is finding inflammation as a potential contributing factor towards to the development of various mental illnesses. A systematic review was conducted to determine the association between parasitic infection and mental illnesses in various African populations. Two parasite groups were evaluated; helminths and protozoans, and four mental illness classifications; depressive disorders, anxiety disorders, schizotypal disorders and unspecified mental illnesses.
Tamer Zaki (Johns Hopkins University) has recently joined the Journal of Fluid Mechanics Editorial Board for JFM Rapids. To celebrate, Tamer participated in a Q&A with the Journal.
