Warm Weather Key Following Herbicide Application

 
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."

White rot, also known as sclerotinia, is a common agricultural fungal disease caused by various virulent species of Sclerotinia. It initially affects the root system (mycelium) before spreading to the aerial parts through the dissemination of spores.

Sclerotinia is undoubtedly a disease of major economic importance, and very damaging in the event of a heavy attack.

All these attacks come from the primary inoculum stored in the soil: sclerotia. These forms of resistance can survive in the soil for over 10 years, maintaining constant contamination of susceptible host crops, causing symptoms on the crop and replenishing the soil inoculum with new sclerotia.
