Biofumigation Cover Crops PART 2 Pest & diseases & impact on soil-borne diseases

There are many brassica species and cultivars that can be grown as biofumigants or cover crops. 

These brassicas are typically thought of as cool seasons options but work by the cover crop project has looked at how they perform across the year in southern Queensland. And some results will surprise!

In this webinar Dr John Duff and Kelvin Montagu summarise the results of trials growing more than 12 different biofumigants at different times of the year in Gatton and Bundaberg. 

Part 2 of the webinar looks at the potential pest and disease issues while growing the cover crops and the potential impact on soil-bourne diseases (Sclerotium rolfsii, Sclerotinia sclerotiorum & Macrophomina phaseolina) following incorporation. 

Key features summarised across the year include:

  • Biomass produced - how well they grew (Part 1)
  • Glucosinolate production - how "hot" was the biomass (Part 1)
  • Any pest and disease issues during growth (Part 2)
  • Early indications of their impact on some soil-borne diseases.(Part 2)
