“…Resistance gene flow is mediated by seeds, playing an important role in the dissemination of Amaranthus spp. herbicide resistant (Yanniccari et al, 2023). Therefore, rotation and combination of herbicides, as well as integration with non-chemical measures, are essential for controlling and preventing the selection of resistant biotypes (Braz and Takano, 2022;Soltani et al, 2023).…”

Amaranthus species are extremely problematic weeds due to their aggressiveness and resistance, being Amaranthus palmeri S. Watson, Amaranthus retroflexus L., Amaranthus tuberculatus (Moq.) J. D. Sauer, and Amaranthus hybridus L. prominent worldwide. The present research aimed to study A. hybridus populations in Paraguay where the use of glyphosate and chlorimuron herbicides presented management challenges. This research was conducted in the municipalities of Corpus Christi and Hernandarias, Paraguay, in 2016, 2017, 2018, 2019, and 2020. Weed seeds with resistance indicators were collected, cultivated, and following a screening process, cultivated for seed production (heritability up to F2), and the seeds were collected to obtain the herbicide dose-response curve. The herbicides glyphosate and chlorimuron were tested in portions of 1-8, 1-4, 1-2, 1, 2, 4, and 8 times the recommended dose on the package inserts (720 g acid equivalent (ae) ha 1 and 20 g active ingredient (ai) ha1, respectively). Among the A. hybridus populations evaluated in Paraguay, biotype from Hernandarias with multiple resistance to ALS-inhibiting (HRAC 2) and EPSPs-inhibiting (HRAC 9) herbicides, and biotype from Corpus Christi with resistance to ALS-inhibiting herbicides (HRAC 2) were found. Therefore, rotation and combination of herbicides, as well as integration with non-chemical measures, are essential to control and prevent selection of resistant biotypes. Studies aimed to develop integrated weed management plans are essential for effective control. In countries like Paraguay, this becomes imperative because of the lack of research on this topic.

“…Another impulse in their adoption has come after the development of herbicide‐resistant (HR) crops, which increased the use of herbicides in crop post‐emergent conditions (e.g., glyphosate), which helped improve overall weed control efficacy (Bonny, 2008) and weed management programmes (Duke, 2005). The recurrent use of herbicides, however, has led to the evolution of HR weed species worldwide (Busi et al, 2021; Heap, 2014; Hulme, 2022; Liu et al, 2019; Powles & Shaner, 2001; Yanniccari, Gaines, et al, 2022).…”

We reviewed and performed a quantitative synthesis on herbicide‐resistant weeds from rain‐fed crops in Argentina. Twenty‐four weed species distributed in the main extensive crops (soybean, maize, wheat, barley, oilseed rape, sunflower, chickpea and peanut) have evolved herbicide resistance. Of the total, 54% are grasses, 88% are annual species and 63% are cross‐pollinated species. The most representative families were Poaceae with 54% resistant species, followed by Brassicaceae with 17%, and Asteraceae with 13%. Buenos Aires, Santa Fe and Córdoba were the provinces with the most documented cases of resistance (35%, 33% and 30%, respectively). The proportion of cases resistant to pre‐emergence herbicides was 10%, whereas the proportion of cases resistant to post‐emergence herbicides was 90%. Glyphosate was the herbicide with the highest incidence (92%) of resistance among weed species, followed by 29% of species that evolved resistance to ALS‐inhibiting herbicides. Whereas resistance to auxin‐like herbicides comprised 17% of the weed species, acetyl‐CoA carboxylase (8%) and protoporphyrinogen oxidase (4%) inhibiting herbicides showed the least incidence of resistance evolution among weeds. The highest number of resistant species was identified in soybean (19), followed by maize (13), wheat/barley (10) and fallow (9). Weed species with a higher number of resistant populations to a higher number of herbicide mode of action were Amaranthus hybridus, A. palmeri, Lolium multiflorum and Raphanus sativus. The change in the production system since the mid‐1990s, based on the use of herbicides (glyphosate mainly) to control weeds, is likely to account for the notorious increase in the average rate of evolution of herbicide‐resistant weeds in Argentina.
