Breaking the critical-use barriers preventing Australian horticulture from phasing out methyl bromide (BS04009)

What was it all about?
Australian horticulture continued to face one of its greatest challenges of the modern era – the phase-out of methyl bromide (MB) due to its ozone depleting properties. For 50 years, the industries had used MB to disinfest soils of pathogens, weeds and pests, and to maximise yields. This project was conducted to identify alternatives for industries applying to the UN for critical-use exemptions to retain MB use (especially strawberry runners, strawberry fruit, and flower industries). It evaluated novel production methods that mitigated the need for soil disinfestation, including soil-less production and tissue culture, in addition to alternative soil fumigants. The future integration of these treatments offered growers a mechanism for reducing their reliance on chemical fumigation, increasing the efficacy of alternative fumigants, improving soil health and increasing the sustainability of their industries. Through this research, the number of industries who applied for CUEs fell by 80 per cent since the commencement of this project, and MB use in Australia had decreased by 110 tonnes pa. The identification of alternatives to MB through this and previous projects had prevented losses in Australian horticulture worth over $100 million annually.
