“…21,29,[38][39][40] The low glyphosate absorption observed in the GRP was likely due to differences in the external leaf surfaces between populations, [40][41][42] while impaired translocation resulted from the greater retention of herbicide near to the treated area. 21,39 The strongest evidence has shown that the sequestration of glyphosate into the vacuole is the main NTSR mechanism responsible for altering the translocation patterns of this herbicide, 17, 43,44 which is regulated by tonoplastactive transporters. 44 Enhanced metabolism as NTSR mechanism has been reported in plants at most herbicide action sites, 16 but never for glyphosate.…”

“…Glyphosate is a systemic and non-residual and post-emergence (POST) herbicide that controls a wide range of weeds [12], making it preferred by the Mexican citrus growers [7,13]. The doses recommended by the manufacturers of this herbicide range from 700 to 2100 g ae ha −1 [14], according to the weed species, phenological stage, and infestation level.…”

“…Due to the frequent glyphosate applications, most Mexican citrus growers have widely adopted and applied doses ranging from 720 to 1080 g ae ha −1 for up to 15 years [9]. The high dependence of glyphosate-based herbicides has led to the selection of resistant populations of Bidens pilosa [15], Eleusine indica [4], Leptochloa virgata [7], and Parthenium hysterophorus [13] between 2010 and 2016 in the citrus-producing region of the states of Puebla and Veracruz, Gulf of Mexico.…”

Glyphosate is a cheap herbicide that has been used to control a wide range of weeds (4–6 times/year) in citrus groves of the Gulf of Mexico; however, its excessive use has selected for glyphosate-resistant weeds. We evaluated the efficacy and economic viability of 13 herbicide treatments (glyphosate combined with PRE- and/or POST-emergence herbicides and other alternative treatments), applied in tank-mixture or sequence, to control glyphosate-resistant weeds in two Persian lime groves (referred to as SM-I and SM-II) of the municipality of Acateno, Puebla, during two years (2014 and 2015). The SM-I and SM-II fields had 243 and 346 weeds/m2, respectively, composed mainly of Bidens pilosa and Leptochloa virgata. Echinochloa colona was also frequent in SM-II. The glyphosate alone treatments (1080, 1440, or 1800 g ae ha−1) presented control levels of the total weed population ranging from 64% to 85% at 15, 30, and 45 d after treatment (DAT) in both fields. Mixtures of glyphosate with grass herbicides such as fluazifop-p-butyl, sethoxydim, and clethodim efficiently controlled E. colona and L. virgata, but favored the regrowth of B. pilosa. The sequential applications of glyphosate + (bromacil + diuron) and glufosinate + oxyfluorfen controlled more than 85% the total weed community for more than 75 days. However, these treatments were between 360% and 390% more expensive (1.79 and 1.89 $/day ha−1 of satisfactory weed control, respectively), compared to the representative treatment (glyphosate 1080 g ae ha−1 = USD $29.0 ha−1). In practical and economic terms, glufosinate alone was the best treatment controlling glyphosate resistant weeds maintaining control levels >80% for at least 60 DAT ($1.35/day ha−1). The rest of the treatments, applied in tank-mix or in sequence with glyphosate, had similar or lower control levels (~70%) than glyphosate at 1080 g ae ha−1. The adoption of glufosiante alone, glufosinate + oxyfluorfen or glyphosate + (bromacil + diuron) must consider the cost of satisfactory weed control per day, the period of weed control, as well as other factors associated with production costs to obtain an integrated weed management in the short and long term.

Dominican farmers have started to apply synthetic auxin herbicides (SAH) as the main alternative to mitigate the impacts of the occurrence of glyphosate resistant (GR) Parthenium hysterophorus populations in citrus orchards. A GR P. hysterophorus population survived field labeled rates of glyphosate, 2,4-D, dicamba and picloram, which showed poor control (<50%). In in vivo assays, resistance levels to glyphosate were high, and moderate to picloram, dicamba and 2,4-D. Sequencing the 5enolpyruvylshikimate-3-phosphate synthase gene revealed the double Thr-102-Ile and Pro-106-Ser (TIPS) amino acid substitution conferring resistance to glyphosate. Additionally, reduced absorption and impaired translocation contributed to this resistance. Regarding SAH, impaired 2,4-D transport and enhanced metabolism were confirmed in resistant plants. The application of malathion improved the efficacy of SAH (control >50%), showing that metabolism of these herbicides was mediated by cytochrome P450 enzymes. This study reports for the first time, multiple resistance to SAH and glyphosate in P. hysterophorus.
