Cameron G., Kendal, SK

"In the past two years I have used Simplicity and OcTTain XL tank mix on my wheat crops and have had excellent results on the growing spectrum of tough weeds. The fields are clean and I have had excellent crop safety as well.”

Graham D., Saskatoon, SK

“We chose to use OcTTain XL because of its Group 4 chemistry and its activity on kochia. We were very pleased with how well it worked and how good of a kill we got in our wheat. We will definitely be using OcTTain XL in the future."

Ed S., Milestone, SK

"OcTTain XL is a superior broadleaf, wide spectrum product with short rainfastness. It is not hard on the crop and is effective on hard to kill weeds such as kochia.”
