Where Are the Kudzu Bugs?

Dr. Dominic Reisig

We have rapidly become accustomed to dealing with kudzu bugs in our soybeans throughout the season.  So the question is, where are they now?

I have been slow to join the bandwagon, but am now on board.  I think the cold winter has knocked our populations back.  Many folks have noted dead bugs in overwintering spots.  Furthermore, spots where kudzu bugs are showing up now are near traditional “hot spots” where they have overwintered.  Because of this, I think our greatest chance for kudzu bug infestations are going to be localized around these traditional hot spots.  You probably shouldn’t expect kudzu bugs to show up at threshold levels in new spots this year.

Believe it or not, the kudzu bug migration into soybeans is in full-swing.  It is really wimpy compared to previous years.  From what I can gather, our population levels are 10-20 times lower than last year.  Right now, kudzu bugs are moving into soybeans, mating and laying eggs.  I have noticed nymphs within the past weeks.  We can expect a few fields to hit threshold within a couple weeks.  If you don’t find kudzu bugs at one nymph per sweep (one per “swoosh” of the net), you don’t need to treat.

It is especially critical to use a sweep net in situations like this year.  We can expect most of our fields at risk for kudzu bug (which aren’t many) to be borderline situations.  Many fields in the past were obvious treatment situations.  Those fields were so full of kudzu bugs that you could smell them through the AC system pulling up to the field.  This year,  you will find one nymph per sweep a lot easier an quicker using the sweep new than you will walking into a field and parting the canopy.  Small hairy green nymphs blend in with the stems and will be difficult to spot.  Most fields won’t need to be treated for this insect!

How a Desire to Lead Brought This Wheat Breeder to Canada

Video: How a Desire to Lead Brought This Wheat Breeder to Canada

Gurcharn Singh Brar is a wheat breeder whose path meandered from the breadbaskets of Punjab, India, to the sprawling fields of the Prairies. In a candid conversation, Brar shared insights into his journey, the challenges faced, and the undying passion that fuels his quest for better crops.

It all began with a childhood rooted in the wheat fields of Punjab, where agriculture isn’t just a livelihood but a way of life. His fascination with wheat and its potential led him to pursue a bachelor’s degree in agricultural sciences at Punjab Agricultural University. It was during this time that he encountered the spectre of rust diseases, particularly stripe rust, which plagued the region’s wheat crops. Determined to combat this menace, he set his sights on a journey that would take him across continents.

Venturing abroad for his graduate studies, he found himself in Saskatchewan at the Crop Development Centre (CDC), working under the mentorship of renowned researchers like Randy Kutcher and Pierre Hucl. Here, he delved deep into the world of wheat genetics, focusing on stripe rust resistance — a quest that would shape his academic pursuits for years to come.

After completing his master’s and Ph.D. in six and a half years, he embarked on a professional journey that would see him traverse academia and research. From brief stints as a research officer to landing his dream faculty position at the University of British Columbia’s Plant Science program, his career trajectory was marked by a strong drive to make a difference in the world of wheat.

Despite the allure of British Columbia’s unique agricultural landscape, he found himself wanting to return to the vast expanses of the Prairies, where wheat reigns supreme. He recently returned to the Prairies and is the new wheat breeder at the University of Alberta in Edmonton.

“The opportunity to lead an established wheat breeding program at the University of Alberta was a dream come true. With the necessary resources and infrastructure in place, I’m excited to drive innovation and develop high-yielding wheat varieties tailored to the unique conditions of northern Canada,” he says.

Brar, one of Seed World Canada‘s 2024 Next-Gen Leaders, has become known for identifying novel sources of resistance to priority diseases and his efforts in developing wheat germplasm with multiple disease-resistant traits.

In addition to his groundbreaking research, Brar is committed to mentoring the next generation of agricultural scientists.

“I believe in nurturing talent and empowering students to pursue their passions,” he says. “Watching my students grow and thrive in their research endeavours is hugely rewarding.”

As he looks ahead, Brar’s vision for the future of wheat breeding is clear: “My number one target is to develop high-yielding wheat varieties adapted to the northern climates of Canada. By focusing on early maturity and strong straw traits, we can maximize yield potential while ensuring resilience to environmental challenges.”

His decision to also join the Prairie Recommending Committee for Wheat, Rye, and Triticale (PGDC) executive as member-at-large came from a desire to play an even more important role in the world of Canadian cereals.
