Harvest weed seed control pioneer Dr Michael Walsh is convinced it is, and explains here why the tactic can be effectively deployed against northern region weeds.
Hundreds of researchers, scientists, agronomists and weed control officers from around Australia have gathered in Sydney this week to talk latest weed control strategies at the 21st Australasian Weeds Conference.
Weed management practices in the grains and cropping sector are under scrutiny as field practitioners collaborate with researchers use technology to manage problem weeds in farming systems. View details of the 21st Australasian Weeds Conference in Sydney next week.
Robotic sensing systems with the capacity to identify weeds within a crop are being developed as part of the next advance in weed control technology.
With sowthistle undergoing changes in emergence patterns and developing resistance to a wide array of herbicide groups, the only form of herbicide control available late in the season is the use of desiccants.
Temperature may be a key factor in the development of resistance to the broad spectrum herbicide, glyphosate, in weed species such as sowthistle.
Mallee Farming Systems (MSF) trials on non-wetting sands consistently show that the increased surface soil moisture, crop establishment, crop biomass and crop/brome competition effects achieved through edge-row sowing can reduce brome grass seed set.
In the light of increasing herbicide resistance in many weeds, strong crop competition is required to do more of the ‘heavy lifting’ within an integrated weed management program.
Farmers in 2018 looking to manage weeds and the threat of herbicide resistance are spoilt for choice when it comes to harvest weed seed control with seven tools to choose from.
Anecdotal evidence of the value of chaff heaps as a stock feed has proven that there is money to be made from using chaff heaps, and probably chaff lines, as a summer feed source for sheep.
