What’s the sticking point? Better pre-em efficacy in stubble retention systems

Pre-emergent herbicides are a valuable tool to underpin crop competition and suppress weed seed production in-crop, but when growers also want to harness the power of retained stubble they often run into a sticking point where pre-emergent herbicide efficacy is compromised. Most growers and advisors are aware that products such as trifluralin are quite tightly bound if they contact stubble during application, however, AHRI research associate Dr Yaseen Khalil has been working to shed light on the behaviour of the newer pre-emergent herbicides and how to use them in no-till, stubble retention farming systems.

Chickpea vs annual ryegrass – shaking off the handicap

Chickpeas are short and annual ryegrass takes advantage!

At 5’2″, Jonte Hall is pretty short by everyday standards, let alone by Harlem Globetrotter standards. Nicknamed ‘Too Tall’, recently-retired guard Jonte is the smallest player to wear the Globetrotter’s jersey since the team was founded in 1926.

Globetrotter veteran Herbert ‘Flight Time’ Lang, a more conventional-sized 6-foot-3 forward, is quoted as saying: “Too Tall is proof that if you stay focused, act positive and take advantage of opportunities, good things can happen.”

So, how can chickpea play to its strengths & win?

Selfish weeds can manipulate the nitrogen cycle to suit themselves

Weeds are selfish, self-centred, narcissistic, manipulative pieces of work that will do whatever it takes to make themselves look good and make the other plants around them look bad. Some weeds are so self-obsessed that they can manipulate the soil nitrogen into a form that is just the way they like it. New research by Cathryn O’Sullivan from CSIRO is showing that some weeds release chemicals from their roots that slow down the bacteria that are essential to the nitrogen cycle, retaining nitrogen in the ammonium form that weeds can potentially take up faster than crop plants. Totally selfish! Click through to get the details.

How a new wheat variety could compete with weeds like Jonah Lomu did on the field

Jonah Lomu stood at 6’5”, weighed 120kg, and ran the 100m in a lazy 10.7 seconds. He could play the power game, the speed game, and he could step. He was the ultimate competitor. Mace wheat, on the other hand, is agile, dependable, and can play the yield game, but its ability to compete with weeds is limited. However, yield is king, and hence Mace has been an extremely successful variety where weeds are under adequate control. What if we could have a wheat variety that could play the yield game and the competition game? What would that look like?
