Recently published research in the journal Weed Technology shows that two electrical control treatments in pastures could substantially reduce tall fescue seedhead production without significantly diminishing forage yield.…
Fall-applied residual herbicides are among the best available options to use for glyphosate-resistant (GR) Italian ryegrass control, according to a newly published research article in the Weed Science Society of America (WSSA) Weed Technology journal.…
Until now, not much was known about the influence that nozzle type and application volume have on weed control efficacy with remotely piloted aerial application systems (RPAASs). However, new research shows that RPAAS applications using low-drift nozzles at low spray volumes (1.0–1.5 gallons/acre) can achieve weed control levels comparable to ground sprayer applications at 10 gallons/acre in turf.
A strategy utilizing both preemergence (PRE) and postemergence (POST) herbicide treatments optimized weed control outcomes in early planted soybean. Researchers conducted their study in 2021 at three locations across Central Illinois.
Diflufenican, a new mode of action herbicide for preemergence use in corn, demonstrates effectiveness as an integrated weed management strategy for multiple-herbicide resistant (MHP) waterhemp (Amaranthus tuberculatus) control. That’s the conclusion from a recently published research article in the journal Weed Technology, a journal of the Weed Science Society of America (WSSA)
Farmers and land-managers looking to reduce their herbicide applications now have another promising option via machine-vision technology. That’s the summary from a recently published research article in Weed Technology, a journal of the Weed Science Society of America (WSSA).
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.
Palmer amaranth is widely recognized as one of the most troublesome weed species in U.S. agriculture. It was first introduced in Minnesota in 2016 through contaminated seed mixes used for conservation plantings.…
Junglerice has become a significant problem in dicamba-resistant cotton and soybean crops. In Tennessee, for example, it is found in 76 percent of dicamba-resistant cotton fields and 64 percent of dicamba-resistant soybean fields.…
Horseweed is undoubtedly one of the most troublesome weeds in the world. Herbicide-resistant populations are now found in 18 countries, and many are resistant to multiple herbicide sites of action.…
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.…
Control of invasive brush on southwestern U.S. rangelands is a continual struggle. Industry-standard herbicide treatments typically knock brushy weeds back, but not out.…
Studies show that pH is one of the many factors impacting dicamba volatility. In fact, the EPA now requires a pH of 5.0 or higher in its registration of new dicamba formulations for dicamba-resistant crops.…
Kochia is a highly invasive weed known to be resistant to multiple herbicides. In the Great Plains region, kochia populations have now evolved resistance to dicamba.…
Cultivars of soybean and cotton that are tolerant of dicamba and glyphosate have been a big hit with growers, allowing them to treat broadleaf weeds throughout the growing season – without damaging their crops.…
Spring-applied herbicides are no match for henbit, a winter annual weed found in more than 50 crops – including corn, cotton and soybean.…
Fall-applied residual herbicides are often used to control glyphosate-resistant Italian ryegrass – especially in the Mid-South. But growers who use rice as a rotational crop need to beware.…
Watermelon growers face tough weed control challenges. One example: Crop seedlings need to be planted with plenty of elbow room – leaving wide spaces where broadleaf and grassy weeds can become established and reduce yields.…
With the introduction of crops engineered for resistance to the auxin herbicides, concern has soared about unintentional injury to auxin-sensitive crops through off-target spray drift, volatility and spray tank contamination.…
Australian farmers have long considered harvest-time weed seed control their “last chance” opportunity to battle herbicide-resistant weeds that survive in-crop treatments.…
Scientists at Purdue University have just answered an important question that has plagued many corn and soybean growers. Why does mixing glyphosate with other selective herbicides sometimes fail to control glyphosate-resistant giant ragweed plants?…
Fall-planted cover crops are frequently a component of integrated weed control programs in herbicide-resistant soybeans. But does it matter which cover crop is used?…
With the recent introduction of soybean and cotton traits resistant to synthetic auxin herbicides, farmers have new, much needed options for managing glyphosate-resistant broadleaf weeds. Researchers writing in the journal Weed Technology say use of the auxins isn’t without risk.
Cover crops are attracting widespread attention for the benefits they provide in crop rotations, especially for soil health. However, many growers of corn and soybean crops know it can be challenging to establish fall-seeded cover crops.
The Weed Science Society of America (WSSA) and Cambridge University Press are pleased to announce the formation of a new publishing partnership beginning in January 2017.

How long will humankind survive? Besides the fact that we have been able to eliminate ourselves with nuclear weapons for decades, even without a third world war, the challenge to take care of the resources of our planet remains; we need to use them in a way that our children and their children can have a place on Earth as well.

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.
