Verna B., Prince Albert, SK

“In our operation, our game plan is simple: give our crops the best possible chance to produce top yielding, high quality product. The quest for a successful and abundant harvest must start with prudent planning. With PrePass, our fields get that ‘spring cleaning’ to give our cereals the advantage they need for an aggressive start. Weeds are suppressed because of the ‘SoilActive technology’ PrePass provides, and has proven advantageous for a stronger, healthier, more abundant crop. We score with PrePass!”

Emile D., Aylsham, SK

“I have used PrePass and have been getting excellent control of perennial weeds and some control of flushing annuals in the spring. Thanks for a product you can rely on.”

Russell H., Cudworth, SK

“We've used PrePass for pre-seed burn down exclusively over the past couple of years and have been very pleased with the results. There is very good residual control well into our post emergence weed spraying and the dandelion control has been excellent.”
