With spring seeding well underway, many farmers are turning their attention to spraying for weeds.
Provincial Weed Specialist Jeanette Gaultier has a few tips for producers before they head out onto the field.
"For the systemic herbicides, when you're working with glyphosate or any of the group 2's or group 4's, we always have that 8-2-2 rule. You're looking for daytime temperatures of about eight degrees for at least two hours for at least two days after application. Often we focus on the day of application, but if you aren't getting that warm weather after, you're not going to get good movement through the weeds."
Gaultier says when using a contact product, for pre-seed or early weed control, it's not as important to have good weather afterwards, but definitely on the day of application, it's critical to have temperatures in double digits.
She adds lots of sun is beneficial.
