“…Repeated application of ACCase inhibitors for the last several years has resulted in the evolution of 44 grass weed species resistant to this herbicide chemistry (Heap, 2014). In fact, resistance to ACCase inhibitors has become the third most frequent type of weed resistance (Kukorelli et al, 2013). Therefore, in the fields with ACCase inhibiting herbicide-resistant weed(s), ACCase inhibitors should be tank-mixed with other herbicides that can effectively control resistant weeds without antagonism.…”

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these herbicides has not yet been documented. Greenhouse experiments were conducted to evaluate the response of glufosinate-, glyphosate-, and imidazolinone-resistant volunteer corn to 20 pre-emergence (PRE) and 17 post-emergence (POST) soybean herbicides. Cumulative emergence of volunteer corn was not affected by PRE soybean herbicides compared with the nontreated control regardless of herbicide-resistant trait at 21 days after treatment (DAT). Although comparable with several other treatments, clomazone provided ≥ 90% control of glufosinate-and imidazolinone-resistant volunteer corn at 21 DAT. The POST soybean herbicides were applied when volunteer corn plants were at the 2 to 3 or 5 to 6 leaf stage. The ACCase-inhibiting herbicides, including clethodim, fenoxaprop plus fluazifop, fluazifop, quizalofop, and sethoxydim, provided ≥ 96 and ≥ 85% control of the 2 to 3 or 5 to 6 leaf stage volunteer corn, respectively, regardless of the herbicide-resistance trait at 28 DAT. Glyphosate tank mixed with acifluorfen, chlorimuron-ethyl, or imidazolinones usually provided > 83% control of glufosinate-and imidazolinone-resistant volunteer corn when sprayed at the 2 to 3 leaf stage at 28 DAT, but control was ≤ 71% for the 5 to 6 leaf stage volunteer corn. Similar results were usually reflected in volunteer corn biomass. It is concluded that PRE soybean herbicides partially controlled volunteer corn; therefore, ACCase inhibiting herbicides are the only highly effective option for soybean growers.

“…No other known mutations were found in the two examined regions of the CT domain. The Trp-2027-Cys mutation has been extensively shown to link to APPs-resistance in several grass weed species Liu et al, 2007;Beckie et al, 2012;Gherekhloo et al, 2012;Kukorelli et al, 2013;Li et al, 2014) and particularly to fluazifop-P-butyl in Goosegrass (Cha et al, 2014;Jalaludin et al, 2014), Sudan grass (Kershner et al, 2012), and Japanese foxtail (Xu et al, 2013). Thus, it is our conclusion that a R. cochinchinensis population from Costa Rica has evolved resistance to fluazifop-P-butyl and the mechanism of resistance is based on an altered target site conferred by the Trp-2027-Cys mutation.…”

Rottboellia cochinchinensis is an annual grass weed species known as itchgrass, or "caminadora" in America´s Spanish speaking countries, and has become a major and troublesome weed in several crops. The application of fluazifop-P-butyl at recommended rates (125 g a.i. ha-1) was observed to be failing to control itchgrass in a field in San José, Upala county, Alajuela province, Costa Rica. Plants from the putative resistant R. cochinchinensis population survived fluazifop-P-butyl when treated with 250 g a.i. ha-1 (2X label rate) at the three- to four-leaf stage under greenhouse conditions. PCR amplification and sequencing of partial carboxyl transferase domain (CT) of the acetyl-CoA carboxylase (ACCase) gene were used to determine the molecular mechanism of resistance. A single non-synonymous point mutation from TGG (susceptible plants) to TGC (putative resistant plants) that leads to a Trp-2027-Cys substitution was found. This Trp-2027-Cys mutation is known to confer resistance to all aryloxyphenoxyproprionate (APP) herbicides to which fluazifop-P-butyl belongs. To the best of our knowledge, this is the first report of fluazifop-P-butyl resistance and a mutation at position 2027 for a Costa Rican R. cochinchinensis population.

“…fluazifop-p-butyl) act on the meristematic tissues of monocotyledonous plants, being translocated by the phloem after absorption by the leaves (Kukorelli et al, 2013). At the cellular level, these graminicides block the biosynthesis of fatty acids, making it impossible to form lipids and, consequently, affecting the integrity of the cell membrane.…”

“…The authors concluded that high doses of fluazifop-p-butyl were not selective to melon and cucumber, reducing the dry matter of these plants, as observed for haloxyfop-R methyl in the present study. In general terms, dicotyledonous species do not present the homomeric plastid ACCase enzyme (Incledon & Hall, 1997;Kukorelli, Reisinger, & Pinke, 2013), which is the main focus of inhibition in this class of herbicides (aryloxyphenoxypropionic). Therefore, it is probable that the negative effect observed in these studies is due to the fact that the depolarization of the plasma membrane of the cells is greater than their repolarization capacity.…”

The objective of this study was to evaluate the selectivity of fluazifop-p-butyl and haloxyfop-R methyl ester on Eucalyptus urograndis (clone GG100), as well as the use of fluazifop-p-butyl for control of Panicum maximum and Urochloa brizantha. Two experiments were conducted in 15-liter capacity pots, in a completely randomized design with four replications. The first experiment consisted of seven treatments, in which fluazifop-p-butyl and haloxyfop-R methyl ester were sprayed at 15, 30 and 37 days after planting (DAP) and a control plot without application. In the second experiment, the treatments consisted of a factorial 4 × 2 (four application periods and two weed species), in which three seedlings of P. maximum or U. brizantha were transplanted per pot. In both experiments, at 90 DAP, plant height, stem diameter, leaf area and total dry matter of eucalyptus were evaluated. In the second experiment, besides the morphological parameters, the percentage of weed control was evaluated. The data was submitted to analysis of variance by F test, and the means compared by Tukey test at the level of 5% of probability. Both herbicides did not cause visual effects of phytointoxication in eucalyptus, but haloxyfop-R methyl ester was not selective to clone GG100 (E. urograndis). Fluazifop-p-butyl was selective to clone GG100, providing better control in the first application period (15 DAP) but only for P. maximum, which negatively affected the initial development of eucalyptus, while U. brizantha was not efficiently controlled with the usage of fluazifop-p-butyl.
