unique advantage. These farmers indicated the lack of residual gives them greater flexibility
to choose which crops can follow in the rotation.

Improved weed control.
CleanStart Plus controls all of the same weeds as glyphosate – but with much faster action.
Where it stands out is its early control of spring germinating dandelions, chickweed, fleabane and lambsquarters.
Weed Grower comments
Chickweed “Chickweed was very small and CleanStart Plus stopped its growth.”
Dandelion “Impressed with control of dandelion when I saw "check/miss" in field.” “Only carcasses that were noticeable
Lambsquarters “The one thing that impressed me was how quickly it acted on some of the weeds.”
Quackgrass “Really impressed with quackgrass control 5 days after; at about 7-10 days the quack grass was smoked.”
Shepherd’s Purse “Pretty good – looked better than straight glyphosate.”
Sow Thistle “Impressed with the weed control. The weeds were definitely dead.”
Redroot Pigweed “Worked very well on smaller weeds, field is very clean even now.”
“Everything died down quicker with CleanStart Plus than a straight glyphosate application. With
CleanStart Plus the weeds were dead within a week. With Roundup you don’t see anything within
that time.” Eddie Zehetner, Grower, Hensall, ON
“With CleanStart Plus you really had to look to find a weed afterwards. It did what we were hoping.
There’s no reason we wouldn’t use it again.”
John Bradish, Grower, Talbotville, ON
“We were impressed that we didn’t see any escapes of the real big ‘woody’ broadleaves. At harvest we
looked at the bottom of the canopy. There was very little sign of new weed growth after harvest.”
Randy Martin, Crop Specialist, Sprucedale AgroMart, Sprucedale, ON
