“…The rapidity of appearance of herbicide résistance is influenced by the characteristics of the weed species, the herbicide, and the usage pattern of the herbicide (Gressel and Segel 1990 1992, 1993Heap et al 1993;Morrison étal. 1989;Primiani étal.…”

“…It is likely that there are many différent mutations and mechanisms of résis-tance in thèse species. For instance, in two ACCase-inhibitor résistant populations of wild oats, one was found to resist diclofop via increased metabolism, whilst the other resisted via an altered plasma membrane response (Devine et al 1992(Devine et al , 1993. In one population of green foxtail, the mechanism of résistance was due to an altération of the ACCase enzyme (Maries et al 1993).…”

Les programmes proactifs de gestion de la résistance aux herbicides sont basés sur la détection rapide des populations résistantes et sur la connaissance des combinaisons de mauvaises herbes et d'herbicides prédisposées au développement de cette résistance. Les mauvaises herbes annuelles, prolifiques productrices de graines, génétiquement variées et exposées de façon répétée à des herbicides du même mode d'action, sont sujettes au développement rapide de la résistance. Quand la résistance est soupçonnée, des échantillons de graines sont recueillis et évalués par un bioessai du plant entier. Ces bioessais sont conduits en champ, en chambre de croissance ou en plats de Pétri. Des courbes complètes de réponse aux doses sont tracées en utilisant une population sensible aux herbicides et une population soupçonnée de résistance. Le bioessai conduit en chambre de croissance est la méthode la plus fiable d'identification de nouveaux cas de résistance aux herbicides. Les bioessais basés sur la détection biochimique d'un seul mécanisme de résistance ne sont pas fiables pour la détection de nouveaux cas de résistance.Proactive herbicide resistance management programs rely upon early detection of resistant populations and knowledge of which combinations of weed and herbicide are prone to the development of resistance. Annual weeds that are prolific seed producers, genetically diverse, and repeatedly exposed to a single herbicide mode of action, are prone to rapid development of resistance. When resistance is suspected, seed samples are collected and evaluated using a whole plant bioassay. Whole plant bioassays are conducted underfield, growth room, or Petri dish conditions. Complete dose response curves for the suspected resistant and a reference susceptible population are used to verify resistance. Bioassay, conducted in growth rooms, is the most reliable method for identification of new cases of herbicide resistance. Bioassays, based on the biochemical detection of a single mechanism of resistance, are not reliable for screening for new occurrences of resistance

Dinitroanilines inhibit cell division in susceptible species by binding to p-tubulin, and therefore interfère with tubulin polymerization (Devine et al 1993).

“…However, subséquent research (Anthony et al 1998) has shown that a base change in the a tubulin gène of goosegrass results in an amino acid change from threonine to isoleucine that confers résistance to dinitroanilines. The mechanism of green foxtail résis-tance to ACCase inhibitors is due to an insensitive ACCase (Maries et al 1993). The green foxtail accession from Spain has two mechanisms of résistance within the plant to triazines, an altération in the target site of photosystem II and enhanced metabolism (De Prado et al 2000).…”

Des sétaires vertes (Setaria viridis) présumées résistantes aux inhibiteurs de l'acétolactate synthase (ALS) ont été identifiées en 1999 au Wisconsin, É.-U., dans un champ de soja (Glycine max) issu d'un semis direct. La résistance aux herbicides imidazolinone et sulfonylurée a été caractérisée au niveau de la plante entière et de celui des enzymes. Ces sétaires vertes au stade trois à quatre feuilles étaient respectivement 1020, 53 et 6,5 fois plus résistantes à l'imazethapyr, à l'imazamox et au nicosulfuron que les sétaires sensibles. L'ALS in vivo était respectivement 1300 et 1,7 fois plus résistante à l'imazethapyr et au nicosulfuron. Ces résultats laissent supposer que ce groupe de sétaires vertes était très résistant à l'imazethapyr et à l'imazamox, et que la résistance est associée à un enzyme ALS insensible.Green foxtail (Setaria viridis) plants putatively resistant to acetolactate synthase (ALS) inhibitors were identified in a Wisconsin USA no-tillage soybean (Glycine max) field in 1999. Resistance to imidazolinone and sulfonylurea herbicides was characterized at the whole-plant level and enzyme level. Three- to four-leaf stage green foxtail plants were 1020, 53, and 6.5-fold resistant to imazethapyr, imazamox, and nicosulfuron, respectively, compared to susceptible plants. In vivo ALS was 1300 and 1.7-fold resistant to imazethapyr and nicosulfuron, respectively. These results suggested that this green foxtail accession was highly resistant to imazethapyr and imazamox, and that resistance was associated with an insensitive ALS enzyme

A Diclofop-methyl-ResistantAvena sterilisBiotype with a Herbicide-Resistant Acetyl-coenzyme A Carboxylase and Enhanced Metabolism of Diclofop-methyl

An Avena sterilis biotype was found to be highly resistant to aryloxyphenoxypropionate (APP) herbicides, especially diclofop‐methyl. At the enzyme level, this biotype contained a modified acetyl‐coenzyme A carboxylase (ACCase) with six‐fold resistance to diclofop acid. Absorption and translocation of [14C]diclofop‐methyl applied to the leaf axil of the two‐leaf stage plants were similar in both susceptible and resistant biotypes. However, the rate of metabolism of [14C]diclofop was increased 1·5‐fold in this resistant biotype compared to the susceptible. Experiments with tetcyclacis, a cytochrome P450 monooxygenase inhibitor, indicated that inhibition of this enhanced diclofop metabolism increased diclofop‐methyl phytotoxicity in this biotype. Studies with ten individual families of the resistant biotype indicated that both mechanisms of resistance, an altered target site and enhanced metabolism, are present in each individual of the population. Hence, it is likely that these two mechanisms of resistance both contribute to resistance in this biotype. © 1997 SCI.
