Glyphosate-resistance evolution in weeds is evident globally, especially in areas where transgenic glyphosate-resistant crops dominate. Resistance to glyphosate is currently known in 16 weed species, including rigid ryegrass in Australia. Following the first report of glyphosate resistance in 1998, there are now 78 documented glyphosate-resistant populations of rigid ryegrass in grain-growing r...

Natural products have been postulated as an alternative to the use of synthetic herbicides in pest control. The latter compounds caused numerous problems and these include appearance resistance such herbicides. Aminophenoxazinones are natural that shown multiple biological activities, pharmacological or phytotoxic effects. In case phytotoxicity, mode action aminophenoxazinones has not widely ex...

Weeds are a major impediment to crop and pasture production profitability in Australian farming systems, knowledge of their occurrence is vital devising weed management solutions. This study examined the relationships between species from observations made during surveys randomly selected fields grain and/or production. Between 2013 2017, 996 across New South Wales (NSW) were surveyed record de...

Laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant Lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. Factors evaluated were Lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 dS cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). The maximum germination in salinity stres...

Pelargonic acid is the most successful natural herbicide and can contribute to reducing synthetic herbicides, but information on its efficacy contrasting. Given high cost, a reduction of rate could facilitate spread use this herbicide. Two greenhouse three field experiments were conducted evaluate herbicidal different doses pelargonic several weeds (Abutilon theophrasti, Alopecurus myosuroides,...
