Getting weed seeds into the chaff fraction
Separating the chaff (including the weed seeds) from the straw is a great way to retain more crop residue at harvest. There are several harvest weed seed control (HWSC) systems that manage just the chaff, including chaff decks, chaff carts and chaff lining. All these systems rely on the weed seed entering the front of the header and then being captured in the chaff stream.

The lack of crop competition in drought-affected crops leaves the door wide open for more weeds to germinate and set seed, adding to weed control costs in future years.Leave a comment Continue reading
Grain grower Leigh Bryan doesn’t shy away from an unconventional idea. His crop-guided shielded sprayer is working a treat, he is confident with chaff lining and now he is testing the possible advantages of zero row spacing.
When glyphosate-resistant summer grass starts to cause yield losses in cotton, growers obviously need to add some non-glyphosate options to their system to protect yields and prevent further weed blowouts. The questions then become where to add non-glyphosate tactics to get most benefit, and how many are needed?
Recently we started a hashtag on Twitter to share information about paired row sowing. We used the hashtag #Pairedrow. You can still use it now to engage in the discussion and tag WeedSmart. Thank you to everyone who has already contributed to the discussion about paired row sowing on Twitter. Here is a summary of the pros and cons.
You’ve got to love the names of some of the brands out there! Below are the names of some of the paired row sowing options that growers had tried.
