AgLife: State-of-the-art breeding site opens in Horsham

Australian plant-breeding company InterGrain officially opened its new state-of-the-art, purpose-built facility on Horsham’s Stawell Road this month.

Features include enhanced pest and temperature control and dust extraction systems, alongside unique machinery. 

Site operations manager Dave Watson said the new site offered efficiency through a range of purpose-built machines, one of which is a thresher – his brainchild and unique to the site.

“It is much cleaner than it was in the past – we have a bigger space, and new aspects – it’s a much better environment to be in,” he said.

“We have added efficiency and cleanliness, which give us purity and integrity.

“It also allows for future growth – we outgrew our previous sites at Plumpton Road, and now we have room for our expanding operation.” 

The Horsham facility is the company’s east coast hub, its other site is in Perth. 

The hub employs about six people, and up to 12 at its seasonal height at Horsham, and more than 80 people across both sites.

“We just do cereals at the moment – barley, wheat and oats – and are working to get better varieties for farmers,” Mr Watson said.

“It takes about eight to 10 years to get the seed to market, so it’s a big process.

“We breed to find that one or two out of a yield that will suit different environments around the country.”

InterGrain chief executive Tress Walmsley said InterGrain started operations in Horsham in 2010.

“The facility is a significant investment and a crucial hub for our breeding activities,” she said.

“This site enables us to translate national breeding investment into grain varieties with strong regional fit, ensuring our future wheat and barley varieties perform where it matters most – in growers’ paddocks across Australia.  

“Just as importantly, the facility represents a step-change in working conditions and workplace health and safety for our team, providing modern, fit-for-purpose infrastructure is central to attracting and retaining highly skilled staff, which ultimately underpins our ability to deliver innovation and value to growers over the long term.”
