Tim Schmidt stopped in to meet with Karen Kirkby, a member from the Department of Primary Industries, looking into Pathogen Resistance within the hemp industry in Australia among many other areas of interest.

The image featuring the two hemp leaves is an experiment the DPI are running, here’s what Karen had to say about it.

“I am using a detached leaf assay to screen variety susceptibility to Botrytis cinerea and also we are using this method to screen the efficacy of potential organic, soft chemicals and biological products.

The image on the left shows a detached hemp leaf with a Botrytis fungal plug. The leaves are incubated and then the leaf lesion is measured.

The image on the right is a detached hemp leaf with a Botrytis fungal plug. This leaf has been sprayed with a product and no lesion recorded on the leaf, showing the possible benefits of the product in reducing Botrytis cinerea in the hemp industry in Australia. 

All experiments are randomised with 20 replicates and each experiment repeated twice.

The information gained from this research will assist in evaluating variety differences for pathogen resistance, provide data on chemical/product efficacy required for permit applications and potentially be used to inform growers for future variety selection based on disease risk.”
