Resistant weeds continue to confound control efforts

CropLife  (1 October 2016)

In the annals of weed scientists, 2017 will mark a milestone of sorts. This will be the 60th anniversary of the discovery of the first known herbicide-resistant weeds in 1957 — a spreading dayflower found in a Hawaiian sugarcane field and a wild carrot variety found in Ontario, Canada, that both showed resistance to up to five times the normal usage dosage of synthetic auxin herbicides. In other instances, researchers have found altering farming practices can help in herbicide-resistant weed control such as Palmer amaranth. » Go to article

Integrated weed control holds promise for cassava revolution in smallholder farms, says Cornell professor

Africa Science News (26 September 2016)

Integrating diverse but proven weed management options could help small-scale farmers overcome the limitations posed by weeds and help them maximize the benefits of genetic improvement, according to Prof Ronnie Coffman, Director of International Programs in the College of Agriculture and Life Sciences (IPCALS), Cornell University. Prof Coffman said efforts in weed management should be directed towards helping smallholder farmers. “And I see the use of chemicals as one option that can benefit smallholder cassava farmers,” he added on 2 September in International Institute of Tropical Agriculture (IITA) » Go to article

Herbicide-resistant weeds challenge Kansas farmers' bottom lines

Topeka Capital-Journal (10 September 2016)

Hardy weeds that have developed resistance to herbicides are challenging Kansas soybean and corn farmers to adapt their chemical applications, and some have added tillage back into their control methods. Farmers have shifted their chemical applications, using pre-emergent weed control herbicides and, even though they may continue to use glyphosate, doing so in combination with other herbicides. Farmers also increasingly use new products such as LibertyLink soybeans that are tolerant to the Liberty herbicide, a Glufosinate-ammonium product. » Go to article

Finale (GA) wins the best product 2016 award in Ireland

Pitchcare Magazine & News (7 September 2016)

Finale, a contact herbicide with Glufosinate-ammonium as an active ingredient produced by Bayer CropScience, wins the award for the Best Product 2016 at this year's annual GLAS amenity trade show in Ireland. Since coming onto the market in April 2016, the product has already received unprecedented interest. The herbicide has proven to be particularly effective around bunker and path edges in Ireland.

Growers consider switch to LibertyLink soybean management

Ohio Ag Net (31 August 2016)

With continued problems with marestail and ragweeds in the United States, many growers consider to switch to LibertyLink soybeans for 2017. The LibertyLink system is a good choice for management of glyphosate-resistant populations of these weeds, along with waterhemp and Palmer amaranth. It is essential to use the appropriate approach to LibertyLink soybeans to get the most out of it. Accordingly, Ohio Ag Net lists practical and useful recommendations for soybean growers in the United States. » Go to article

GA is not linked to allergic and non-allergic wheeze among farmers

News Medical (14 August 2016)

New research from North Carolina State University connects several pesticides commonly used by farmers with both allergic and non-allergic wheeze, which can be a sensitive marker for early airway problems. The 78 pesticides included 45 herbicides and plant growth regulators, 25 insecticides, six fungicides, one fumigant and one rodenticide. In the herbicide group, 18 were associated with at least one wheeze outcome, 14 with non-allergic wheeze and 10 with allergic wheeze. Glufosinate-ammonium was not associated with either type of wheeze, which further proves that the herbicide is safe to operators as well as consumers. » Go to article

Cover crops and weed control practices featured at field day in Louisiana

The News Star (2 August 2016)

Cover crops and weed control practices featured at field day in Louisiana
During a recent field day in northeast Louisiana, speakers presented ways to deal with glyphosate-resistant weeds. For instance, AgCenter weed scientists Josh Copes and Donna Lee mentioned showed at a weed control demonstration that incorporating Glufosinate into a herbicide program is beneficial especially when Glyphosate-resistant weeds are present. They also added that herbicide selection should always be made field-by-field with knowledge of the weed spectrum. » Go to article

Fall weed control affects herbicide resistant Palmer Amaranth

Ag Professional (1 August 2016)

Scientists recently conducted a three-year field experiment to determine the impact of in-crop herbicides and fall weed management practices on Palmer amaranth. Tehy compared glyphosate-only weed control with preemergence herbicides, a residual glufosinate applied postemergence, and a variety of harvest-time and post-harvest management options – used alone or in combination. The glufosinate-containing residual herbicide program proved to be superior to the glyphosate-containing residual program in reducing Palmer amaranth seed production. » Go to article

Do not underestimate the need for a balanced weed control

Corn and Soybean Digest (27 July 2016)

Palmer’s explosion is causing soybean field destruction, hand weeding and burning windrows behind the combine. To that end, farmers need to activate a variety of sophisticated methods to manage all kinds of weeds and at the same time make sure that they avoid weed resistance. Glufosinate-ammonium is part of the bigger solution. Perry Galloway, a farmer from Arkansas facing serious weed resistance issues, seeks to establish a balanced Integrated Weed Management program and argues: "All I can do is hope and pray that glufosinate lasts a few more seasons". » Go to article

What is Glufosinate-ammonium?

It is one of the most effective herbicides available for treating weeds in orchards, vineyards and other herbicide-resistant LibertyLink crops such as soybeans, corn, canola or cotton. Crucially, its distinguishing chemistry and ‘mode of action’ help farmers avoid weed resistance.
