JOE: Hi my name is Joe Vink. I'm the Product Lead for corn and bean herbicides with Syngenta Canada and today I'm standing in front of a bunch of different weed samples. Here to my left I have glyphosate resistant Canada fleabane, waterhemp in the middle, and then your standard old red root pigweed. So when you look at glyphosate resistant Canada fleabane, a couple things that really matter in terms of the herbicide application is the size of that rosette. So anytime you're applying herbicides for weed management earlier is always better, so if you make a mistake spraying or herbicide spray it earlier than too late because once the weeds get too big it doesn't matter what herbicide you have and how effective that herbicide normally is on the weed. If it's too big you'll start to lose control. So with Canada fleabane you'd be looking to target rosettes in that three to four inch stage like what I'm holding in my hand here. 
[Scene zooms in to closer shots of the fleabane, seedling stage of fleabane, large rosettes, an image of a tall bolt, another large rosette, while switching back to shot of Joe speaking to the camera between each one.]
JOE: Or even better if you had rosettes that were even in the seedling stage. Typically the fall germinated Canada fleabane tend to be a little bigger so they germinate in the fall, they overwinter, they have time to grow in the spring when it starts to warm up and the rosettes can get quite large and so it's really important to get in there to manage that Canada fleabane as soon as the weather allows you. So once you're past four to six inches on that rosette it's going to become difficult to manage the Canada fleabane. Same with if it bolts, so the spring germ typically emerges and it moves from the rosette. Sometimes it doesn't even have a rosette, it emerges and goes right into that bolting stage. So if you have a bolt that starts to be greater than or taller than a pop-can or about roughly four inches., again if your herbicide is not on before that and the bolt becomes greater than the four inches, it's going to become difficult to manage glyphosate resistant Canada fleabane. This last pot here would be an example of a rosette that would be too large for optimal efficacy of any herbicide rated for control on Canada fleabane.

JOE: If I move on to waterhemp and red root pigweed, there are a few distinguishing characteristics that you'd want to look for to define waterhemp versus red root pigweed. First of all would be the hair or no hair on the stems. So with waterhemp you would not expect to see any hair on the stems or on the leaves. There can be bio types with hairs on waterhemp. If there are some, they tend to be very sparse especially if you're holding it next to a red root pigweed, you would definitely tell that the red root pigweed has a lot more hair on the stem and leaves compared to the waterhemp. Another one is the leaf shape. So waterhemp tends to have a more linear shape, a bit of a longer shape to them, whereas red root pigweed tends to be more round, a little more broad, in terms of of that leaf structure. And finally the last key distinguishing characteristic between waterhemp and red root pigweed is really just the overall look of the plant so waterhemp tends to have a glossy look, plasticky kind of look to it, maybe a little bit wet and it's very smooth to the touch, going back into the lack of hairs on waterhemp. Red root pigweed tends to be dull in color and a little bit more rough to the touch. So those are a few of the key distinguishing features between waterhemp and red root pigweed. Why does it matter? It matters because waterhemp has the ability to evolve resistance to multiple sites of action of herbicides. So there's six-way resistant herbicide resistant waterhemp in the US. There's confirmed four-way resistant waterhemp here in Ontario, and so it's really important to understand how to identify the difference between waterhemp and redroot pigweed because it helps you tailor your weed management program appropriately to manage a more challenging weed. I think the other difference with waterhemp is it germinates from the spring right through the fall. So anytime there's a rain event with waterhemp, you really need to be focused on having your best residual herbicide down in the system to try to delay and prevent those multiple flushes of the waterhemp because it can become very difficult to control in crop if you're not starting with an excellent pre-emergence program. So from Syngenta we offer Acuron and corn, the best waterhemp herbicide on the market. And in soybean we offer boundary LQD, also excellent control residual control of glyphosate resistant waterhemp.
