“…Obtained results are in accordance with what took place in other regions, where the high reliance on any molecule induces the selection of resistant biotypes [13,15,17,32,33]. This collection was assessed using a seed-biossay with discriminating concentrations of imazapyr + imazapic.…”

Echinochloa crus-galli is the main weed in direct dry-seeded rice systems worldwide and is the target of most herbicide applications. Numerous cases of E. crus-galli biotypes with resistance to herbicides have been reported in different regions of the world; however, to date, no cases have been reported in Uruguay. The purpose of this research is to assess the presence of herbicide-resistant E. crus-galli in the rice fields of Uruguay. More than 40 E. crus-galli biotypes were sampled from eastern to northern regions in different years and assessed following the Herbicide Resistance Action Committee (HRAC) protocols of confirmation, using the herbicides propanil, quinclorac, clomazone, bispyribac–sodium, penoxsulam, imazapyr + imazapic, profoxidim and cyhalofop. Herbicides rates included 0, 0.125, 0.25, 0.50, 1, 2, 4 and 8 times the label rate. Most E. crus-galli biotypes (35) resulted as resistant to quinclorac. Furthermore, resistance was confirmed to propanil in at least seven biotypes, 12 to imazapyr + imazapic, and three to penoxsulam. Five biotypes showed multiple resistance to propanil and quinclorac, and one biotype was resistant to quinclorac, penoxsulam and imazapyr + imazapic. No biotype showed confirmed resistance to clomazone, bispyribac-sodium, cyhalofop or profoxidim—herbicides that ensure satisfactory control. The presence of E. crus-galli herbicide resistant-biotypes reduces herbicide options, threatening rice production in Uruguay. In this context, a redesign of the productive systems would represent an opportunity to complement the chemical control, integrating larger-scale cultural and management practices.

“…Penoxsulam is one of the most important herbicides to be used in China since 2008, and has been an excellent tool for rice weed management. However, recent reports of cross‐ and multiple‐resistant E. crus‐galli have raised concerns about sustainable weed control options in rice . Current estimates are that nearly 2 × 10 6 ha in the Yangtze River area and Ningxia Province are severely impacted by ALS inhibitor resistance (Liu D, Hunan Plant Protection Institute, personal communication).…”

Herbicide-resistant weeds have been observed since the early years of synthetic herbicide development in the 1950s and 1960s. Since that time there has been a consistent increase in the number of cases of herbicide resistance and the impact of herbicide-resistant weeds. Although the nature of crop production varies widely around the world, herbicides have become a primary tool for weed control in most areas. Dependence on herbicides continues to increase as global populations migrate away from rural areas to cities and the agricultural labor force declines. This increased use of herbicides and the concurrent selection pressure have resulted in a rise in cases of multiple resistance, leaving some farmers with few or no herbicide options for certain weed infestations. Global population and economic forces drive many farmer choices regarding crop production and weed control. The challenge is how to insert best management practices into the decision-making process while addressing various economic and regulatory needs. This review endeavors to provide a current overview of herbicide resistance challenges in the major crop production areas of the world and discusses some research initiatives designed to address portions of the problem. © 2017 Society of Chemical Industry.

“…In the same experiment, the corresponding ED50 values for the resistant biotype were 254, 49, and 170 g ha -1 , while for the susceptible biotype were 10, 6, and 12 g ha -1 . Chen et al (2016) found that the ED50 values of penoxsulam-resistant barnyard grass biotypes in The dose-response regression equation is y = C + {D -C) / 1 + exp[b(log(x) -log(ED50))]}, where y is shoot number or fresh weight expressed as percent of the untreated mean control, b is the slope of the curve around the ED50, C denotes the lower limit of the response when the rate x approaches infinity, D is the upper limit when the rate approaches zero, and x is the herbicide rate in g ai ha -1 + 0.1.

The repeated use of herbicides with the same mode of action maybe has led to buildup of resistant late watergrass (Echinochloa phyllopogon (Stapf) Stapf ex Kossenko) populations. Thus, pot experiment was conducted to evaluate the level of penoxsulam-and bispyribac-resistance in seven late watergrass biotypes collected from water-seeded rice fields in Greece. Their susceptibility to imazamox and profoxydim was also studied. Furthermore, the efficacy of various herbicide combinations against the resistant late watergrass biotypes, as well as on rice sedge (Cyperus difformis L.) were evaluated in four field experiments. In pot experiment, two biotypes were resistant to both herbicides, while three biotypes were moderately resistant to penoxsulam with one of these simultaneously resistant to bispyribac. Four biotypes were also cross-resistant to imazamox, while all biotypes were susceptible to profoxydim. In field experiments, the double applications of penoxsulam or bispyribac applied at 18 d after seeding (DAS) followed by profoxydim plus halosulfuron at 35 DAS constantly provided the greatest rice yield and satisfactory control of both weeds. Conclusively, late watergrass resistant to penoxsulam and bispyribac biotypes have been built. In particular, rates up to 8 times the recommended rate did not provide acceptable weed control. Effective control of these biotypes and high rice yield can be achieved by double applications of herbicides with different modes of action (penoxsulam or bispyribac until the third leaf of rice [18 DAS] followed by profoxydim at seven-to eight-leaves growth stage [35 DAS]). Simultaneous control of late emerged rice sedge can be achieved by the addition of halosulfuron in the tank-mix with profoxydim.
