Ryan Orr investigated the effect of nitrogen fertiliser and micronutrient availability on Fusarium wilt of banana. He found that nitrogen fertiliser, unlike micronutrient availability, may provide a means to reduce disease severity. Farmers in Australia and internationally are using his finding to improve production methods for infected farms.
