Summer grasses can drive decision making over summer. The NGN 'Control strategies for key problem weeds in nth NSW' has been developing & evaluating options. Free workshops with @congreve_mark compile the latest info into field-ready management. Details: bit.ly/4ydvAOn

Keen to learn about pre-em efficacy, crop safety & herbicide carryover on marginal soil types? Can we use decision support to guide our knowledge
Get along to Beckom, NSW to hear from @congreve_mark @Mick_T_Rose
RSVP icanrural.com.au/registratio…

You are invited to an afternoon pre-emergent herbicide discussion session and field trial inspection led by Mick Rose from Southern Cross University & @congreve_mark from ICAN Rural.
Details: bit.ly/3TnUJql
On the Wednesday for interested growers and agros
@GRDCNorth NGN field trial walk
1pm Wed 8th July
Warral-Bithramere Rd Tamworth
Residual safety x seeding systems x planting depth
Fallow knockdown demo (glyphosate, glufosinate, paraquat, Group 14 mixes)
Two pre + post-em efficacy trials in wheat
RSVP icanrural.com.au/registratio…
Another example to reinforce that it's not a good idea to mix fast acting contact herbicides (glufosinate) with systematic herbicides that need time to translocate through the plant (glyphosate)

AMS showing its benefits to assist glyphosate in controlling self sown cereals and other grasses. Here it’s been tank mixed with triazines, with and without AMS and control
is chalk and cheese. AMS assisting with Antagonism with group 5 pre ems @CropDoctor54 @robbert115

Autonomy Mark II this time with a lot more tech on board and a remote monitoring system as well. Ornata Ag system controlling the tractor and seeder. DickeyJohn ISO monitoring blockage, bin levels, fan speed and metering. The whole iso display is shared with Ornata Ag.

Double & triple knock jobs working a treat on known resistant ryegrass populations.
1st pass Crucial alone (no spike) then 2nd pass group 14/G + paraquat. 3rd pass if required another paraquat.
Pre ems also synergistic with paraquat eg Overwatch, Boxer, Reflex

MAKING PRE-EMERGENT HERBICIDE SELECTION EASIER!
Selecting a pre-em herbicide can be challenging, particularly when seasonal rainfall is uncertain.

Great field day at the Collie site: Integrated mgt of black/wild oats in wheat using PRE herbicides & crop competition. Need more research. Thanks to growers, agros, @GRDCNorth, @GrainOrana, @QAAFI @UQ_News @UQWeedScience
Worth a read ( in the link) for those thinking about broadacre spraying via drones
First impressions of the DJI Agras T100.
Going to be interesting to find a new operational settings "sweet spot" for this drone.

There has been some recent discussion of clethodim degradation in 'old' formulations that have been in storage for a few years.
Below is another data set to support this observation from one of our 2025 field trials (phalaris in chickpea)
