Herbicides
Gowan Canada's Edge herbicide has been granted a minor use label extension for industrial hemp.
With the introduction of Monsanto’s glyphosate- and dicamba-resistant soybean into the Canadian market in 2017, producers may be wondering if there is any benefit to tank-mixing the two herbicides for weed control.
Weed control in corn and soybeans will only get more complicated and costly.That was a key message by long-time Iowa State University weed scientist Mike Owen in his 2018 weed management update presentation at the Integrated Crop Management Conference in November. He noted the management practices used by many farmers…
Gowan Canada has announced that the Avadex MicroActiv label has been expanded to include peas, in addition to existing crops barley, canary seed, canola, durum, flax and mustard.“As Group 1 and Group 2 resistant wild oats continue to plague more and more fields in the prairies according to the latest ag Canada studies, it…
Harvest quality of milling oats is very important, and growers sometimes utilize harvest aids such as pre-harvest glyphosate. A properly timed application can help growers control perennial weeds and improve crop harvestability, while meeting maximum residue limit (MRL) requirements. However, some buyers have placed restrictions on the use of pre-harvest…
The Herbicide Resistance Summit is a bi-annual conference brought to you by Top Crop Manager (TCM) and a group of generous sponsors that aims to facilitate a more unified understanding of herbicide resistance and promote awareness that all industry members have a role to play in managing the growing threat…
AMVAC Chemical Corporation recently announced its new broad spectrum, low use rate corn herbicide, ImpactZ, has received federal registration from the U.S. Environmental Protection Agency (EPA). ImpactZ herbicide will give growers a new safe and flexible solution for control of tough broadleaf and grass weeds - including glyphosate resistant species…
Corn and soybean growers in Canada have a new tool in the fight against tough and resistant weeds. ZIDUA™ SC is a new Group 15 herbicide from BASF that contains the active ingredient pyroxasulfone."BASF focuses on providing Canadian growers with tools that support current and emerging resistance challenges," said Deven…
The U.S. environmental agency is considering banning sprayings of the agricultural herbicide dicamba after a set deadline next year, according to state officials advising the agency on its response to crop damage linked to the weed killer.Setting a cut-off date, possibly sometime in the first half of 2018, would aim…
Research trials in the U.S., and more recently at the University of Saskatchewan, are proving what’s old is new again. In this case, the use of “old” herbicides such as Avadex, Fortress and Edge are making a comeback of sorts in a weed management system that’s been dubbed “herbicide layering.”
With the confirmation of glyphosate-resistant (Group 9) kochia across the Prairies, a renewed focus on best chemfallow management practices is needed.
Using several herbicides with multiple modes of effective action are essential in combatting resistance, minimizing the weed seedbank and preparing fields for success. A planned herbicide program using multiple modes of action is the best strategy for these tough-to-control weeds. An herbicide that offers multiple modes of action to help…
Premier Tech, an international leader in active ingredients for sustainable agriculture and horticulture, will take the lead in the final steps to bring to full scale the manufacturing and commercialization of a selective bioherbicide. In January, the Horticulture and Agriculture Group signed a license agreement with Agriculture and Agri-Food Canada…
The late harvest in fall 2016 created more than just delays in crop removal – fields were dirty with weed growth and there was limited time for fall herbicide application. As a result, many farmers are expecting weedier fields this spring and will need to be diligent in using the…
Just over 20 years ago, researchers initiated the first bioherbicide research and development program in the country at Agriculture and Agri-Food Canada (AAFC) in Saskatoon. Led by Karen Bailey (who recently retired), the program has made significant advancements in bioherbicide development for horticulture and turf crops, and more recently, promising…
