Updated Greenhouse Insect Management Recommendations For 2016

By Tom Dudek, Michigan State University Extension
 
Greenhouse growers can access the latest MSU insecticide recommendations in a new resource. Eight major greenhouse insect and mite pests are covered, as well as information on growing bee-friendly plants.
 
Michigan State University Extension entomology specialist for ornamentals David Smitley has released his 2016 “Greenhouse Insect Management” document, which serves as recommendations for growers that need to control thrips, aphids, whiteflies, spider mites, broad and cyclamen mites, fungus gnats, mealybugs and Florida fern caterpillar. The guidelines also give information on how to start clean each year to prevent insects from overwintering in greenhouses, the importance and frequency of scouting for insects as well as notes on systemic insecticides, neonicotinoids and pyrethroid insecticides.
 
Smitley has also added a section on practices that contribute to growing bee-friendly plants that include:
 
  • Do not spray flowers in the last two to three weeks before shipping.
  • Do not apply soil drenches of imidacloprid or other neonicotinoids to types of plants that are attractive to bees. Very few annuals are attractive to bees. However, the following annuals are attracted to bees: ageratum, snap dragons, calendula, cosmos, dahlia and zinnia. Many perennials are attractive to bees, and a list of them will be made available to you soon.
  • Do not use imidacloprid soil drenches on flowering trees and shrubs that are attractive to bees.
  • Read bee warning information on pesticide labels and avoid practices that are harmful to bees.

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.
