“…Although the Trp574Leu mutation had little effect on AHAS binding capacity for tribenuron‐methyl, and the number of hydrogen bonds did not change, the pHB42 (with Trp574Leu) subpopulation displayed very high resistance and the AHAS enzyme became insensitive to tribenuron‐methyl. Our previous research also confirmed that resistant D. sophia carrying the Trp574 mutation evolved high resistance or cross‐resistance to all classes of AHAS‐inhibiting herbicides. Additionally, the Trp574 mutation in Raphanus raphanistrum , Poa annua and Echinochloa oryzicola vasing also causes strong resistance to AHAS‐inhibiting herbicides.…”

“…Mutations at Pro197 do not affect the access of IMI herbicides but prevent access of SU herbicides 39 . Hence, most Pro197 mutations usually cause weed species to evolve resistance to SU but not IMI herbicides, such as occurs in L. rigidum 40 and D. sophia 27 . The Asp376Glu mutation caused the greatest reduction in hydrogen bonds, which might provide a possible explanation for the pHB25 subpopulation having the highest resistance and its AHAS enzyme having the greatest insensitivity to tribenuron-methyl compared with subpopulations pHB8, pHB22, pHB23, pHB24 and pHB42 ( Table 5).…”

“…In the early 80's, herbicides from the IMI and SU groups were the first ALS products available for soybeans in Brazil, while diclosulam (TP) was released only in 1993 (Beckie and Tardif, 2012;Deng et al, 2017). Another fact that may have contributed to the relatively decrease in diclosulam use in relation to both imazethapyr and chlorimuron is the quantity of companies manufacturing these commercial herbicides with those actives (eight and nine, respectively), which is significantly superior to a single company producing herbicides based on diclosulam (AGROFIT, 2018).…”

Greater beggarticks (Bidens pilosa and Bidens subalternans) biotypes have been under selection pressure of ALS-inhibitors since early 90’s in Brazil. The objectives of this work were to investigate whether there are different cross-resistance patterns among ALS-inhibitors herbicides in Bidens spp. biotypes; to understand the geographic distribution of resistance patterns in grains producing regions in Brazil; and evaluate the possibility of multiple resistance to ALS-inhibitors, EPSPs inhibitor and photosystem II inhibitors. Dose-response experiments were carried out with imazethapyr, chlorimuron and diclosulam in three populations. Sensibility to others 34 populations both from Paraná State (PR) and from others Brazilian regions were also evaluated. The dose-response assay revealed cross-resistance with different patterns. One population was resistant to all three herbicides, the second population was tolerant to both imazethapyr and chlorimuron, but not to diclosulam, while a third population was resistant merely to imazethapyr. The results exhibited different cross-resistance patterns, since they can be found in other Bidens spp. populations. However, no relationship was observed between geographic areas where samples were collected and resistance patterns. Conclusively, the most frequent resistance pattern was R2 (resistance to imazethapyr, chlorimuron and diclosulam).

“…It is well demonstrated that TSR is the predominant type of resistance to ALS-inhibitor herbicides in weeds (Deng et al, 2017). In essence, the development of target-site resistance depends on repeated usage of a single herbicide (or group of related herbicides).…”

Catchweed Bedstraw (Galium aparine) is a problematic weed, which has become increasingly difficult to control with herbicides in Iran. The aim of this study was to screen selected putative-resistant populations of G. aparine for resistance to auxinic herbicides 2,4-D+MCPA and ALS-inhibiting herbicides sulfosulfuron, tribenuron-methyl, mesosulfuron-methyl + iodosulfuron-methyl-sodium. Populations of G. aparine were collected from different wheat fields in the west of Kermanshah, where herbicide-use pattern is typical for Iran. Herbicide resistance to premixed herbicide 2,4-D+MCPA was confirmed in several populations. More populations of G. aparine showed cross-resistance to ALS-inhibiting herbicides examined in this research. Some populations were found to have developed multiple resistant to both auxinic and ALS herbicides. Generally, the level of resistance to ALS-inhibitor herbicides was higher than that of auxin analog herbicides.
