Harvest Weed Management Control

This very sobering report by ISU Bob Hartzler refers extensively to Australian experience in herbicide ineffectiveness to discuss what we have to look forward to in the US.

 

More weeds going to seed mean more for pre and post herbicides to address, and they are being smothered.  We need to attack the seed bank.

 

The Australians have some machinery like chaff mills and other methods like fire to address that.  Some may work here.  They are all expensive or have other risks.
