Research scientists from the Department of Primary Industries and Regional Development (DPIRD) presented several important research findings at the biennial event, while garnering the latest advances in plant pathology to benefit WA growers.
Kith Jayasena presented research that identified a fungus (Fusarium acuminatum), which caused root rot and crown discolouration in vetch plants at Esperance in 2023.
This was the first time this pathogen had been reported on vetch in Australia and DPIRD’s research will help growers to manage the disease.
Daniel Huberli discussed effective management practices for Rhizoctonia root rot (Rhizoctonia solani AG8), which costs Australian grain growers in low and medium rainfall zones about $168 million per annum.
Results from demonstration trials in collaboration with growers have helped to develop valuable disease management strategies, including mechanical tillage and deeper sowing.
Ahmed Saad presented on the role of mechanical soil amelioration, like deep ripping and mouldboard ploughing, and incorporating compost amendments to reduce Rhizoctonia root rot inoculum.
The research revealed the disease responds differently to various soil amelioration treatments, offering growers valuable insights and another potential tool to manage this significant disease.
DPIRD crop protection manager Helen Spafford said plant pathology research was a key component of the department’s research efforts to help WA grain growers protect crop potential and profitability.
“The department’s crop protection team works alongside industry to manage pest, weed and disease threats to WA grains crops, arming growers with the latest knowledge and tools to aid on-farm productivity,” Dr Spafford said.
“DPIRD’s new website has a wealth of information to assist industry, as well as details of research priorities and collaborations to optimise WA grains production.”
The department’s free monthly Protecting WA Crops newsletter has essential advice and intelligence to help growers and consultants to navigate the growing season, which is available on the DPIRD website.
