Farmers face increasing pressure every year from existing and emerging weeds, as well as increasing issues with weed resistance. Agricultural companies are constantly developing and launching new and improved products and formulations to try and stay ahead of the curve.
The following is a synopsis of the new herbicide products from BASF, UPL AgroSolutions, Nufarm, FMC Canada and Corteva Agriscience farmers in Western Canada can look out for in 2021 and 2022.
BASF has two new, pre-seed herbicide products coming soon — Certitude, which will be available for the 2021 season and Smoulder, which will be available in 2022.
Certitude is the first Group 27 herbicide approved for pre-seed use in Canada and contains the active ingredient topramezone. The herbicide controls resistant kochia and supports target plant populations and crop sustainability by managing canola volunteers that can host pathogens such as clubroot and blackleg, which have the potential to impact the health of current and future canola crops.
Smoulder is another pre-seed herbicide for wheat and barley growers containing the active ingredients saflufenacil and metsulfuron-methyl, which provides residual control of volunteer canola and burndown of all Group 2-, 4- and 9-resistant broadleaf weeds.
Available in 2021, Akito is a Group 2 and Group 4 post-emergent herbicide that provides control of hard-to-kill annual and perennial broadleaf weeds in spring wheat, durum wheat, winter wheat, barley and oats. Its combined active ingredients, clopyralid, florasulam and fluroxypyr, provide a tool for managing resistant weeds in a convenient, easy-to-use formulation.
Tricor LQ is a new liquid formulation of the Group 5 Tricor herbicide approved in November 2020 and will provide more tank-mixing options for soybean and potato growers. Tricor is a proven herbicide for control of annual grass and broadleaf weeds in soybeans and potatoes, cereals and many other crops. It also increases control of velvetleaf and several pigweed and lamb’s quarter species in potatoes and soybeans and helps manage glyphosate-tolerant fleabane in soybeans.
Tricor’s active ingredient is metribuzin, which is also effective against ragweed, kochia, foxtail grasses, Johnsongrass, browntop millet and jimsonweed, and is recommended by many weed scientists and consultants as a foundation ingredient for an effective herbicide-resistance management program.
Also approved in November 2020, Strim MTZ is a reformulated Group 5 and Group 15 herbicide that features two modes of action to provide early-season, residual control of annual grasses and broadleaf weeds in soybeans, potatoes and many other crops. The two active ingredients, S-metolachlor and metribuzin, are effective against redroot pigweed, eastern black nightshade, lamb’s quarters and common and giant ragweed. Strim MTZ can also be rotated with different herbicide groups that control the same weeds in a field.
ThunderHawk is a pre-seed herbicide that provides fast-acting broadleaf weed control in the black and dark-brown soil zones of Western Canada. It has three modes of action (Group 2, 4 and 14) and can be tank mixed with glyphosate to provide producers with a pre-seed product that offers longer residual control (up to three weeks) on volunteer canola and management of Group 2-resistant weeds like cleavers, wild mustard, redroot pigweed, stinkweed, shepherd’s purse and kochia.
ThunderHawk can be applied before and up to two days after seeding barley, oats and wheat (spring and winter). There will be a limited supply of ThunderHawk available for the 2021 pre-seed burndown season, so farmers need to book product early with their local crop inputs retailer.
Fierce EZ is a new liquid formulation of a pre-emergent soil active herbicide that offers extended activity on emerging spring broadleaf and grassy weeds for up to eight weeks after activation in pulses, soybeans and wheat. It has two modes of action (Group 14 and 15) with active ingredients flumioxazin and pyroxasulfone, which can be used for field peas, chickpeas, lentils (fall application only), spring wheat and soybeans. Growers can tank mix the product with most burndown and pre-emergent herbicides, including glyphosate.
Command Charge is a new pre-seed, canola herbicide that controls more than 25 emerged and flushing broadleaf weeds and provides extended cleaver control. Command Charge can be tank mixed with glyphosate to provide the only mix of Group 9, Group 13 and Group 14 active ingredients currently on the market.
The Group 14 portion of Command Charge works alongside glyphosate and provides a second effective mode of action on the same target weeds. The Group 13 portion creates a barrier on the soil surface that provides a second round of activity on emerging cleavers. These two modes of action, both working to control cleavers, help reduce opportunities for resistance to build up.
Intruvix herbicide is the only spring burnoff product to offer producers four modes of action (after adding glyphosate) to fight resistance and control more than 30 broadleaf weeds including kochia, cleavers, volunteer canola and narrow-leaved hawk’s beard. Intruvix contains active ingredients from Group 2, Group 4, Group 14 and Group 9 (glyphosate), and combines fast activity with systemic action for cleaner fields and fewer resistant-weed escapes. It can also be used for post-harvest applications on certain crops.
The newest addition to the Enlist weed control system is Enlist 1, a Group 4 herbicide containing 2,4-D choline that provides additional tank-mix flexibility for growers. It is approved for use on Enlist E3 soybeans and Enlist corn and can be tank mixed with glyphosate or Liberty 200 SN to control resistant and hard-to-control broadleaf weeds, including glyphosate-resistant weeds. Its proprietary Colex-D technology provides near-zero volatility and minimizes the potential for drift.
Prominex herbicide provides control of both annual and perennial broadleaf weeds in wheat and barley with the convenience of an all-in-one formulation. It also offers farmers the flexibility to tank mix with the right graminicide partner and phenoxy partner. It is one of the few broadleaf herbicides that allows farmers to choose any graminicide partner.
The new Exhilarate herbicide controls standard value broadleaf weeds, including cleavers and hemp-nettle in wheat and barley, thanks to its overlapping modes of action and Arylex Active ingredient.
Rezuvant XL is a new formulation upgrade of Rezuvant herbicide that combines Group 1 grass weed control with broadleaf technology in wheat and barley. The formulation is a move to an all-in-one formulation versus a co-pack and has a higher loading of fluroxypyr, delivering more consistent and complete broadleaf weed control.
Paradigm PRE is a cereal pre-seed herbicide for control of cleavers, (including Group 2-resistant cleavers), hemp-nettle and more than 25 other key weeds. The Arylex Active in Paradigm PRE also provides consistent broadleaf weed control across variable climatic conditions.
Bindem is a utility modifier that is required with Simplicity GoDRI and broadleaf herbicide tank mixes for product compatibility. With one rate, regardless of water volume used, Bindem provides improved convenience and usability.
