New crop protection products for this summer

New Technology: More options provide greater grower flexibility

Each new year tells its own tale and offers a new mix of tough cropping decisions, with the hope of a perfect growing season and higher yields. Weed and disease management are constant challenges for growers, however, particularly with changing species, the risk of resistance and the impact of weather throughout the growing season.

The crop protection sector is constantly tweaking and adding to its product lines to stay ahead of the curve on weeds and diseases, and Country Guide offers this brief summary of some of the products now (or soon to be) available to growers in Eastern Canada.

As always, consult with chemical company representatives, your adviser or local retailer for more detailed information and guidelines on the specific use of each product.

BASF

Armezon PRO

Registered earlier in 2016 as a pre-mix herbicide, Armezon PRO is promoted for control of broadleaf weeds and improved control of grass weed species, giving growers more options in their corn crops. Armezon PRO combines topramezone (Group 27) with dimethenamid-P (Group 15) for weed control in field and seed corn, as well as sweet corn and popcorn. For broadleaf weeds it provides post-emerge control of ALS-resistant (Group 2) weeds such as lamb’s-quarters, redroot pigweed and eastern black nightshade, as well as glyphosate-resistant species such as Canada fleabane and common and giant ragweed.

By the start of planting, Armezon PRO still had not been scheduled for use in Ontario, so growers should talk to their BASF representatives or their local retailers for more information.

Bayer CropScience

Stratego PRO

This label expansion adds corn and spring wheat in Eastern Canada to Stratego PRO’s existing registration as a fungicide for leaf diseases in soybeans and winter wheat. A broad-spectrum fungicide, Stratego PRO combines prothioconazole (Group 3) with trifloxystrobin (Group 11). In corn, it will provide control of northern leaf blight, grey leaf spot, eye spot and common rust. In spring cereals, it is promoted to control septoria leaf blotch, powdery mildew, tan spot and leaf, stem and stripe rust. Other crops registered for its use include oats, barley and rye.

Infinity FX

Infinity FX is a new tool from Bayer, combining Infinity’s original Group 27 and Group 6 chemistries with a Group 4, making it the newest option in cereal herbicides. The addition of the Group 4 mode of action helps reduce selection pressure for resistance while providing effective weed control. The company says Infinity FX brings systemic and contact properties, for control of broadleaf weeds such as cleavers and wild buckwheat. (In Western Canada, it’s also an option for control of kochia, one of the region’s hardest-to-control weed species).

DuPont

Barricade M

Billed as a new herbicide for Eastern Canada, Barricade M controls tough broadleaf weeds for growers with winter wheat, spring wheat and barley. Its control list contains 22 broadleaf weeds, including cleavers, chickweed, perennial sow thistle, wild buckwheat and dandelion. It also provides suppression of Canada thistle. A multiple mode-of-action product, Barricade M contains four active ingredients from Group 2 and Group 4 for effective control plus a stronger defense against herbicide-resistant weeds, now and in the future. It can be applied as early as three-leaf and as late as just before the flag leaf.

Syngenta

Trivapro

For farming operations with a three-crop rotation, Syngenta has a new addition to its lineup with the foliar fungicide, Trivapro. Three active ingredients — azoxystrobin (Group 11), propiconzole (Group 3) and a new fungicide, benzovindiflupyr (Group 7), known as Solatenole — provide a unique combination of preventive, curative and protective qualities against leaf diseases. In corn, Triavpro is registered to control rust, grey leaf spot, eye spot and northern leaf blight, and can be applied from V6 to tassle. In soybeans, it can be applied at R2 to R3 for control of frogeye leaf spot, Asian soybean rust, anthracnose and powdery mildew, while in cereals, it’s registered against tan spot, powdery mildew, leaf, stem and stripe rust and septoria leaf blotch, among others.

UAP Canada

Authority

Growers in Eastern Canada now have one more herbicide registered for use in soybeans (as well as sunflower and flax). Manufactured by FMC and distributed by UAP Canada, Authority’s active ingredient is sulfentrazone (Group 14). It can be applied on its own or as a tank mix with glyphosate. It’s a pre-plant/pre-emergent solution for broadleaf weed control in soybeans, and provides lasting residual control against lamb’s-quarters, pigweed, eastern black nightshade, waterhemp and seedling Canada fleabane. In addition to its tank-mix capability with glyphosate, Authority also helps with broadleaf weed species that are resistant to Group 5 (triazines) and Group 2 (ALS inhibitors). It also works well with identity preserved (IP) soybeans.
