Decoding Non-Target-Site Herbicide Resistance in Sunflower: The Beginning of the Story

Helia, 2019
Abstract In the last years, many efforts have been made to develop sunflower cultivars showing important agronomical characteristics such as herbicide resistance. These approaches have been focused mainly on resistance to herbicides with the same mode of action, that is acetohydroxyacid synthase (AHAS) inhibitors.

Target-site and non-target site resistance mechanisms are associated with iodosulfuron resistance in Lolium perenne L.

2023
Resistance to iodosulfuron, a herbicide targeting acetolactate synthase (ALS), was identified and characterised in a population of Lolium perenne L. from Canterbury, New Zealand. The resistant population was 264 times more resistant to iodosulfuron than a susceptible population, based on a ratio of the rate corresponding to a 50% reduction in resistant

Non-target-site resistance to ALS-inhibiting herbicides in a Sagittaria trifolia L. population

Pesticide Biochemistry and Physiology, 2017
Sagittaria trifolia L. is one of the most competitive weeds in rice fields in northeastern China. The continuous use of acetolactate synthase (ALS)-inhibitors has led to the evolution of herbicide resistant S. trifolia. A subpopulation BC1, which was derived from the L1 population, was analyzed using DNA sequencing and ALS enzyme activity assays and ...

Non-target-site glyphosate resistance in Echinochloa colona from Western Australia

Crop Protection, 2018
Abstract An Echinochloa colona population from Western Australia has evolved resistance to glyphosate. This current study investigates the physiological, molecular and biochemical basis of glyphosate resistance in this population. To minimise genetic differences the susceptible (S) and resistance (R) phenotypes were isolated from within this ...

Conyza bonariensis resistance to glyphosate and ALS inhibitors involves target and non-target site resistance

Pesticide Biochemistry and Physiology
Herbicide resistance in Conyza bonariensis (hairy fleabane) poses a significant challenge to agricultural systems worldwide. The genetic variability and prolific seed production of this species contribute significantly to its adaptative potential and fast spread in the agricultural fields.

Investigating non‐target site resistance to pyroxsulam in a glyphosate‐resistant Lolium rigidum population

Pest Management Science
Abstract BACKGROUND Resistance to multiple herbicides is common in Lolium rigidum . Here, resistance to acetolactate synthase (ALS)‐ and susceptibility to acetyl‐CoA carboxylase (ACCase)‐inhibiting herbicides was confirmed in a ...

Glyphosate resistance in Ambrosia trifida: Part 2. Rapid response physiology and non‐target‐site resistance

Pest Management Science, 2017
AbstractBACKGROUNDThe glyphosate‐resistant rapid response (GR RR) resistance mechanism in Ambrosia trifida is not due to target‐site resistance (TSR) mechanisms. This study explores the physiology of the rapid response and the possibility of reduced translocation and vacuolar sequestration as non‐target‐site resistance (NTSR) mechanisms.RESULTSGR RR ...

Both target-site and non-target-site resistance mechanisms confer mesosulfuron-methyl resistance in Silene conoidea L.

Pesticide Biochemistry and Physiology
Silene conoidea L., a common weed in wheat fields, is mainly controlled by acetolactate synthase (ALS)-inhibiting herbicides such as mesosulfuron-methyl. In this study, we investigated a mesosulfuron-methyl resistant population to elucidate the resistance mechanisms.

Segregation of non‐target‐site resistance to herbicides in multiple‐resistant Alopecurus myosuroides plants

Weed Research, 2015
SummaryNon‐target‐site resistance (NTSR) comprises a set of mechanisms conferring resistance to multiple modes of action. Investigation of the number of loci involved in NTSR will aid in the understanding of these resistance mechanisms. Therefore, six different multiple herbicide‐resistant Alopecurus myosuroides plants with different herbicide history ...
