Through breeding, and the research and development of appropriate agrichemicals, "PSA was now under control and our orchard has continued to produce top quality fruit".
"It is important that consumers understand the value of agrichemicals and the effort that the industry goes to in order to keep consumers safe.
"Each product has been thoroughly researched and industry bodies are always looking at how they can use agrichemicals more efficiently".
Their value spans far beyond the orchard gate. "If we cannot get our products to market due to pest and disease incursions, we have the potential for economic collapse."
Wilson contemplated a career in business "as a safe option" before settling on agribusiness and horticulture.
Reflecting on her choice, Wilson said, "it is the best decision of my life", due to the extensive opportunities and "awesome career pathways".
"My degree is giving me a broad overview of primary industries that very few other degrees can give". When finished, Wilson wants to add value and make a positive difference to horticulture.
The $2500 win would go towards next year's study costs.
When she isn't studying, Wilson leads the Massey Horticultural Society and works as a social media guru for Grassroots Media.
She also completed a summer internship at Zespri, as part of the Quality Assurance team, analysing product issue notifications from world markets.
"In this role, I gained great insight into how a world-leading company utilises the innovation, research and development of the agrichemicals sector to produce a quality product in a sustainable manner."
As President of the Horticultural Society, Wilson organises events that connect industry leaders to the students who might one day work with them.
"I believe the events play an important role in encouraging Massey students to work in the industry where there is both a labour and skills deficit."
Wilson said she enjoyed helping her local community by volunteering at the Te Puke Food Bank – something her grandmother helped set up as a community hub.
"It was a big part of my world" and opened her eyes to the extent of need and the challenges people face.
"Coming from a good home, I realise how blessed I am."
She loves sports including netball, basketball, and volleyball, although she has had to "calm down on sport" during her studies.
Animal and Plant Health NZ chief executive, Mark Ross, said the association was pleased to contribute to the future of someone with so much enthusiasm for the primary industries.
"We were impressed with Sarah's drive and the commitment she showed to enhancing the primary industries.
"It is clear that she will be an asset to the industry, and we wish her well with her career."
Animal and Plant Health NZ offers two scholarships a year to support education and raise awareness of careers in related industries.
