Grower Group Alliance

Host: DPIRD research agronomist Cindy Webster.
Guest Speakers: DPIRD research scientist Dr Dusty Severtson, research scientist Dr Catherine Borger and plant pathologist Geoff Thomas.

In this episode of Grains Convo, DPIRD's crop protection team leaders join Cindy Webster to discuss how below average summer rain and drier start to the season impact pests, weeds and diseases.

Catherine tells us how a dry start influences weed emergence and explains why small rainfall events allow weeds to emerge without activating the herbicide.

Geoff discussed why a limited green bridge impacts disease inoculum carryover and if the diseases to be worried about this season have changed.

Dusty explains why some pests will be reduced and how cooler daytime temperatures impacts pests, particularly RLEM.
