Treating Stink Bugs In Late Soybeans

Sep 26, 2017

By Dr. Dominic Reisig

How late should you treat soybeans? Recent research from Maryland and Suffolk, VA, showed that stink bugs can damage soybeans during R6. In the cage studies, where damage was experienced at R6, stink bugs were infested at levels of 8 per row foot (link to published study). Compare that to published threshold levels of one per row foot (thresholds found here). While we should remain vigilant, these levels are rarely experienced. Stink bugs can still damage soybeans through R7, but much less so than during the previous stages. Seed producers should be more conservative to preserve germination quality.

Also keep in mind that stink bugs are reproducing in soybeans right now. Any nymphs that develop in the crop will slowly disperse to overwintering sites from now through the rest of the fall. It is pretty unlikely that adult stink bugs will invade a field. Those that developed from nymphs in soybean have overwintering on their mind. Those that developed during the summer are probably already in soybeans and have reproduction on their mind. Me? I’ve got the weekend on my mind. Please get out and scout if you haven’t!

Video: New research chair appointed to accelerate crop variety development

Funded by Sask Wheat, the Wheat Pre-Breeding Chair position was established to enhance cereal research breeding and training activities in the USask Crop Development Centre (CDC) by accelerating variety development through applied genomics and pre-breeding strategies.

“As the research chair, Dr. Valentyna Klymiuk will design and deploy leading-edge strategies and technologies to assess genetic diversity for delivery into new crop varieties that will benefit Saskatchewan producers and the agricultural industry,” said Dr. Angela Bedard-Haughn (PhD), dean of the College of Agriculture and Bioresources at USask. “We are grateful to Sask Wheat for investing in USask research as we work to develop the innovative products that strengthen global food security.”

With a primary focus on wheat, Klymiuk’s research will connect discovery research, gene bank exploration, genomics, and breeding to translate gene discovery into improved varieties for Saskatchewan’s growing conditions.
