Herbicide resistant weeds by mode of action and county in Ontario.
Crop injury as a result of Liberty (glufosinate) applied at 8 times the labelled rate.
Severe leaf distortion caused by an application of flumioxazin just prior to corn emergence.
A stunted uneven corn stand caused by flumioxazin being applied post planting and shortly before crop emergence.
A by-product of leaf burn caused by saflufenacil, is that the new growth gets “caught up” in the necrotic leaf tissue causing distorted growth.
Retarded growth caused by a post emergent application of Integrity at the 2-3 leaf stage. The saflufenacil portion had burned off the emerged leaves, but since the growing point was below the ground, the corn was able to regrow.
Leaf injury caused by a post emerge tank-mix contamination of chlorimuron + flumioxazin + glyphosate (Guardian Plus)
A wide shot of Guardian Plus injury caused by tank contamination (10% of labelled rate).
Injury caused by a post emergent application of isoxaflutole/atrazine without the crop safener
Injury caused by an overlap rate of isoxaflutole/atrazine applied post emergent with a crop safener compared to without a crop safener (right)
Another example of injury caused by Infinity (pyrasulfotole/bromoxynil)
Injury caused when Infinity is applied to corn. Note the injury is limited to the leafs most prominent at application.
Tank contamination with Puma at 10% of the labelled rate causing injury to corn.
Another example of injury caused to corn by contamination with Achieve (tralkoxydim) at 10% of labelled rate.
