Growers will also learn to identify predatory mites, parasitoids and other beneficial insects that can contribute to keeping pest populations in check, and the session will explore how growers protect species already doing pest-control work for them.
Entomologist Paul Horne said with many crops carrying strong yield potential this season, growers’ aims should be not to take unnecessary risks with pest control, but to protect potential without automatically adding another input to a program.
Dr Horne said IPM was more than simply choosing not to spray.
“IPM isn’t just doing nothing,” he said.
“If there’s pests there, you have to control them. It’s just how you choose to use it, which products you choose, whether it’s cultural or whether it’s a pesticide.
“All IPM is, is trying to use things in the best possible way so they work together.”
Dr Horne said the distinction would be central to the Main Field Day sessions.
Rather than asking growers to stop using insecticides, presenters will focus on understanding when intervention is required and selecting control options that manage target pests while minimising unnecessary impacts on beneficial species.
Wimmera agronomist Tim Pohlner said while broad-spectrum insecticides could be an inexpensive addition to a tank mix, the lowest-cost product per hectare did not always result in the lowest pest-control cost across a season.
He said removing beneficial insects could leave crops more exposed to subsequent pest populations, while more selective products could have a higher upfront cost but preserve beneficial species and potentially reduce the need for repeat applications.
“Most farmers will want to see an economical return from that long term,” he said.
“Farming is a money-making venture. We’re not doing it as a hobby.”
Mr Pohlner said implementing IPM did not have to mean changing an entire farming system at once, but could start in one paddock as a practical way for growers to build confidence in monitoring and management.
Field day variety
Presenting the latest local research, practical insights and conversations relevant to broadacre farming, the day will have plenty to keep local growers busy.
Attendees can explore the implications of a strong season of rainfall so far, see how trials are responding, explore cutting-edge research and hear from leading researchers and industry experts about what their results could mean for farming operations.
The program covers topics including crop management, weed control, soil nutrition, new varieties, farming systems and ways to maximise yield potential and profitability.
BCG chief executive Fiona Best said the main field day was a chance to get research out of the paddock and into conversations with farmers.
“The day offers a fantastic opportunity for farmers to share knowledge, learn from researchers, and connect with peers,” she said.
“Together, we’re navigating rising costs, making informed decisions, and finding ways to achieve strong yields and healthy, resilient farm businesses.”
Ms Best said whether growers were looking to maximise yield, improve profitability or stay ahead of emerging challenges, the day would contain something for everyone.
Attendance is free for BCG members and $60 for non-members. People can register at bcg.org.au/events.
