Photo of Andrew and Jocelyn Bate at proof-of-concept trials.. Andrew and Jocelyn Bate look to the future of grain growing with an early vision of a prototype agricultural robot undergoing proof-of-concept trials on their family's property near Emerald, Queensland... Andrew said the emphasis on technology that allows the robots to function as a cooperative swarm has already led researchers to develop a "docking and filling" system that enables the AgBots to automatically refuel...

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...

Sprayer setup and using good quality water are critical to ensure full rates of glyphosate are getting to the weeds... Dr Boutsalis says a common reason for poor weed control when using glyphosate is herbicide resistance, ranging from weak resistance to strong resistance... Plants with weak resistance are often controlled with maximum label rates of glyphosate, Dr Boutsalis says, but relying on a herbicide-only option will develop resistance to very high rates...

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)...

Ineffective performance of pre-emergent herbicides due to a large range of factors can often result in weeds escaping control, replenishing the weed seed bank for years to come... Developed for the GRDC by consultants Mark Congreve and John Cameron from ICAN (Independent Consultants Australia Network), the manual covers a broad range of information needed to optimise and understand results from pre-emergent herbicides... Issues covered include stubble and crop interception; loss pathways such as photo degradation and volatilisation; the position of the herbicide in the soil; the influence of soil texture and cation exchange capacity; solubility; binding to clay and organic matter; the influence of soil moisture; half-life and breakdown mechanisms and impacts on crop rotation...

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...
