Field evaluation of selected canola competitive cultivars for suppression of natural weed populations

Research output: Other contribution to conferenceAbstract

Abstract

In 2014–2016, replicated field trials were performed to evaluate mechanisms of weed suppression in Australian canola genotypes in moderate to low rainfall zones at Wagga Wagga (572 mm) and Condobolin (449 mm) NSW, respectively. In 2015–2016,a split plot design with and without trifluralin as the main plot and cultivar as the sub plot was employed for trials; in this experiment 8 cultivars including hybrid and open-pollinated cultivars were assessed.At each site, crop and weed growth were monitored at various phenological stages including early season,vegetative, grain-filling, harvest and post-harvest.Certain cultivars exhibiting early vigour and also the ability to intercept light due to leaf canopy structure were associated with increased suppression of in-crop weed growth in canola trials; in addition, improved post-harvest weed suppression was associated with the presence of remaining crop residues after harvest.

Period09/09/1812/09/18
OtherThe Weed Society of New South Wales Inc., on behalf of the Council of Australasian Weed Societies Inc., will be hosting the 21st Australasian Weeds Conference in the popular Sydney beach side suburb of Manly from 9 - 12 September 2018.  An assortment of field trips will be hosted on Thursday 13 September 2018.

This biennial conference carries on a long tradition of bringing the weed management community together to discuss new developments and share information about cutting-edge and best weed management practices.

The conference attracts over 250 delegates from across Australasia and globally.  Delegates will come together to network with peers, engage with industry sponsors, listen and participate in presentations and field trips on a variety of topics including; 
- New technologies in weed management.
- Biological, mechanical, and chemical weed control and research.
- Herbicide resistance.
- Weeds of crops and pastures.
- Environmental weeds and Weeds of National Significance.
