The economics of weeds — what they cost and the benefits of managing them effectively

Weeds cost the Australian broadacre copping industry millions of dollars annually.

However, we don’t often take the time to calculate what yield reduction they are actually responsible for, or what a well-planned rotation for weed management can make a farming business.

Yield maps are an easy option to assess what weeds can do to the yield of a crop, but a longer term approach is harder to measure.

Chris Minehan, from Rural Management Strategies, joins us to discuss the economic benefits of implementing an integrated weed management approach on your farm.

We will have a look at how you can assess some of the benefits of utilising the Big 6 in your business.

This webinar is facilitated by WeedSmart southern extension agronomist, Chris Davey.

 

Topics covered include

  • Yield losses – What weeds cost us
  • Expenditure on herbicides
  • Lentils
  • WeedSmart Big 6
  • Weed management – farm level
  • Brown manured legume
  • Brown manure gross margin
