Target and non‐target site mechanisms of fungicide resistance and their implications for the management of crop pathogens

Pest Management Science, 2023
Abstract Fungicides are indispensable for high‐quality crops, but the rapid emergence and evolution of fungicide resistance have become the most important issues in modern agriculture. Hence, the sustainability and profitability of agricultural production have been challenged due to the limited number of fungicide chemical classes ...

Dose Splitting Increases Selection for Both Target‐Site and Non‐Target‐Site Fungicide Resistance—A Modelling Analysis [PDF]

Plant Pathology
Fungicide resistance management principles recommend that farmers avoid splitting the total dose applied of a fungicidal mode of action (MoA) across multiple applications per season (‘dose splitting’).

Non-target Site Mechanisms of Resistance to Herbicides

Critical Reviews in Plant Sciences, 2017
ABSTRACTEvolution of resistance in weeds to herbicides is threatening world agricultural production. Weed management has become more complicated with the development of non-target site resistance (NTSR) to herbicides in weeds. The NTSR mechanisms can be caused by herbicide metabolism, altered patterns of translocation, and herbicide absorption ...

Resistance to ALS inhibitors conferred by non-target-site resistance mechanisms in Myosoton aquaticum L.

Pesticide Biochemistry and Physiology, 2022
Myosoton aquaticum L. is a competitive broadleaf weed commonly found in wheat fields in China and has become challenging due to its evolving herbicide resistance. In this study, one subpopulation, RF1 (derived from the tribenuron-methyl-resistant population HN10), with none of the known acetolactate synthase (ALS) resistance mutations was confirmed to ...

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

Helia, 2019
AbstractIn 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.

Transcript Profiling of Non‐Target‐Site Imidazolinone Resistance in Imisun Sunflower

Crop Science, 2018
Imidazolinone resistance found in a wild sunflower (Helianthus annuus L.) population was successfully transferred to a cultivated inbred line developing ‘Imisun’ sunflowers. Genetic regulation of this trait has been reported to involve two genes: Imr1, an allelic variant of ahasl1 locus that codes for acetohydroxyacid synthase catalytic subunit, and ...

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 ...

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.

Non-Target-Site Resistance Mechanisms Endow Multiple Herbicide Resistance to Five Mechanisms of Action in Conyza bonariensis

Journal of Agricultural and Food Chemistry, 2021
The repeated use of herbicides can lead to the selection of multiple resistance weeds. Some populations of Conyza bonariensis occurring in olive groves from southern Spain have developed resistance to various herbicides. This study determined the resistance levels to 2,4-D, glyphosate, diflufenican, paraquat, and tribenuron-methyl in a putative ...
