paraquat and spray.seed (paraquat/ diquat) are not registered for pre-harvest application in cereal or oilseed crops and should not be used under any circumstances including in-crop spray topping, pre-harvest canola dessication or under-the-cutter-bar spraying during swathing or windrowing canola... DO NOT use on crops intended for seed DO NOT harvest for 5 days after application to standing crops DO NOT overspray windrows DO NOT apply to standing crops and again at the time of windrowing.. Keeping an accurate spray diary and adhering to recommended application timing and spray intervals as per the label is crucial...

The use of Group A herbicides in fallow to control grass weeds such as the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (Chloris truncata) - have shown to be a viable option for controlling young weeds... Recent research has investigated the use of some of these herbicides for fallow applications to control grass weeds, in particular the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (C. truncata)... Trial results have shown that a minimum period of 5 to 7 days should occur between applications...

A tactic that has rapidly increased in recent seasons is the use of pre-emergent herbicides, especially in the summer crop and fallow... The presence of stubble or existing vegetation can intercept herbicide before it reaches the soil surface... In a zero till system, it is most likely that allow for weeds to germinate at depth and effect on the binding ability of herbicides the pre-emergent herbicide will need to grow through the herbicide band on the (adsorption)...

A useful new resource for growers and spray operators will help them meet the technical requirements for a successful spraying program in the coming season... "Preparing a spray plan assists with nozzle selection, controller inputs and systems checks," he said... Dr Rainbow said it was also critical to check and record controller settings; use the self-test or test speed function to check the machine for leaks, restrictions and uniform output; and check the machine's output against the spray plan...

A paddock specific strategy for controlling radish is possible by knowing the resistance genetics present and the stage of resistance development- the expenditure required... We can now describe what is happening within paddocks and can explain why products work or do not work, highlighting the importance of growers knowing what genetics they are dealing with... Best Management Practice is not to rely solely on new chemistries but to use mixtures of both old and new chemistry across populations to minimise selection pressure on all groups...

In order to maximise the benefits of fallow sprays, Dow AgroSciences' Rob Buttimor says they need to be managed to the same degree as in-crop sprays so growers do not end up with a mess in the spray tank... "Growers using 2 percent AMS in soft water are effectively wasting their money," Mr Buttimor says... By adding lots of other ions to the spray tank in the form of hard water or soluble liquid herbicides, it neutralizes these charges and the oil droplets can come together to form large oil droplets, oily gels or general glug that will float to the top or sink to the bottom of the spray tank...
