Are you a grain grower battling to contain the increasingly problematic weed common sowthistle?

If yes, the Northern Grower Alliance (NGA) group would like to hear from you as part of a survey of growers and farm advisers in southern Queensland and northern New South Wales, assessing current research and future investment options for controlling this weed.

Common sowthistle is one of the most widespread broadleaf weeds in the northern cropping region. Once predominantly a winter problem it is now a management challenge in almost all seasons.

Although management in-crop can be challenging, control issues are more frequently experienced in fallow situations. Increasing levels of glyphosate resistance have also become a major threat to achieving ‘clean’ fallows for growers in southern Queensland and NSW.

This month the NGA, which is a Grains Research and Development Corporation (GRDC) investment, is conducting a short survey designed to provide a snapshot of current common sowthistle management practices and constraints.

Richard Daniel from NGA said the survey will also help determine how much growers know about the weed, as well as knowledge gaps, which will help guide future research.

GRDC Grower Relations Manager – North, Richard Holzknecht said the short survey was an invaluable opportunity for industry to have input into research investments for one of the most economically significant weeds in the region.

The survey takes 10-15 minutes to complete and can be accessed at https://www.surveymonkey.com/r/FMSPFMR. The survey is open until July 9 2019.
