While southern New South Wales grain growers are looking anxiously for a break in the weather, they need to be vigiliant about monitoring and managing early weeds this season.
Growers trying to juggle large cropping programs will dry sow winter crops, but this has the potential to compromise weed management.
This is further complicated when pre-emergent herbicides have been applied and dry conditions prevail. So we now just want to remind growers of the need to be prepared and monitor and manage for early in-crop weed control.
I also encourage growers to be selective about the paddocks they do dry sow, favouring those that were kept clean last season or planting crop varieties that have a wide range of post-emergent weed control options.
