The Herbicide Action and Injury guide is now available online. The guide looks at pesticides, their modes of action and the identifying symptoms of each herbicide action on susceptible plants.
It is useful for the initial diagnosis of plant injury and for further investigation into the causes of crop damage from herbicides, crop specialist Harry Brook said in a release (issued prior to budget cuts that resulted in his position being eliminated).
“If a picture is worth a thousand words, this document is very verbose,” he said. “There are extensive photos of the injury symptoms of most of the commonly used herbicides.”
The guide can be found at the Alberta government website.
