Expiry dates matter

University of Manitoba Soil Science professor Annemieke Farenhorst says expiry dates on chemicals make sense.

“There’s an expiry date on everything, when we go to the grocery store and we look at an expiry date for milk,” she said. “The same holds for pesticide products so manufacturers usually provide a certain time that you should use the product.”

Farenhorst says expiry dates are an important message from manufacturers on how long they can guarantee the product will work.

Professor Annemieke Farenhorst“Going beyond the expiry date is not advisable,” said University of Manitoba soil science professor Annemieke Farenhorst.

“So going beyond the expiry date is not advisable,” she said.
