Six years of survey data taken from 184 paddocks spanning 14 million ha of land used for crop and pasture production in south-west western Australia were used to assess weed populations, herbicide resistance, integrated weed management (IWM) actions and herbicide use patterns in a dryland agricultural system. Key findings were that weed density within crops was low, with 72% of cropping paddocks containing fewer than 10 grass weeds/m2 at anthesis.

The evolution of herbicide resistance in weedy plants leads to various adaptation traits including flowering time and seed germination.

Asiaminor bluegrass (Polypogon fugax) is one of the main weeds invading Chinese canola fields.

Cinmethylin is a new (old) herbicide being commercialised by BASF that is pre-emergent selective in wheat. Cinmethylin has been shown to be an inhibitor of acyl ACP thioesterase (Campe et al 2018).

Herbicides that inhibit HPPD have become very important. In North America, corn-selective HPPD herbicides have long been used and cases of HPPD herbicide-resistant weeds reported.

The paper “Non-target site resistance to PDS-inhibiting herbicides in a wild radish Raphanus raphanistrum population” is the work of AHRI PhD student Huan Lu.
