herbicide time

Catalogue: GRDC Updates
The cropping area west of the Warrumbungle ranges has many challenges, in the form of herbicide resistance... Trial results showed that inter-row spraying of Gramoxone in wide row chickpeas could be useful, if it were to be registered for this use. . The same principles apply to canola which enables the inclusion of atrazine trifluralin, Avadex Xtra and Dual Gold... Double knock on glyphosate resistant plants: In March 2007, the first experiment (at Bellata) conducted on glyphosate resistant barnyard grass investigated basic combinations of glyphosate followed by either paraquat or Spray...

A definition of double knock is required for those people unfamiliar with the technique... An experiment commenced at Dalby Ag College in November 2006, investigating double knock with combinations of glyphosate and paraquat... As can be seen from Table 1, a single application of either glyphosate or paraquat on pre-tillering barnyard grass (1 st knock) often results in excellent control but usually there are a few survivors...

Early warm weather and storm events have meant conditions are ideal for a flush of summer weeds and the Grains Research and Development Corporation (GRDC) is urging growers to control summer fallow weeds early to maximise effectiveness, preserve precious stored soil moisture and protect the yield potential of future crops... " efficacy is also significantly impacted by temperature and humidity, travel and wind speed, droplet size and viscosity of spraying liquid so it's really important from a cost/benefit and sustainability perspective to adhere to best management recommendations on spray equipment and conditions.".. Pre-emergent herbicides are becoming increasingly used in integrated weed management programs as advisors and growers look to alternative modes of action for hard-to-kill weeds and an increasing range of weeds with resistance to post-emergent herbicides...
