“…In developed countries such as Japan and South Korea, labor for farm work has been limited for some time and hand‐weeding is largely impractical . Countries with developing economies have seen significant migrations of people from rural to urban areas and are already experiencing labor shortages in agriculture . Herbicide selection pressure will increase significantly and more weeds with multiple resistance are likely to arise.…”

“…7,26,27 Natural rubber plantations also are heavily concentrated in these countries and make extensive use of herbicides. 27 Consequently, resistance to several SOAs, including glyphosate, paraquat, ALS, auxin, ACCase and glufosinate, have been documented in species such as Eleusine indica, Hedyotis verticillata, Clidemia hirta and Chromolaena odorata. 28 In the case of glufosinate-resistant E. indica reported on a palm plantation, the grower had indicated using up to 24 applications annually.…”

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.

“…This herbicide can be used to manage R-WR, but needs to be applied at least 15 days before rice sowing (Eleftherohorinos and Dhima, 2002). Clearfield ® rice cultivars are still the mainstay in Malaysian rice production (Dilipkumar et al, 2017). To maintain the viability of the technology, it is essential to follow the three basic principles stated in the stewardship guidelines, namely, (1) planting Clearfield ® rice for not more than two consecutive seasons, (2) using certified seed, and (3) spraying the registered imidazolinone herbicide at the specified rate plus correct timing.…”

“…Recently, many complaints have been received at MARDI from local farmers regarding the failure of OnDuty ® to control weedy rice in Clearfield ® rice fields (Dilipkumar et al, 2017). The occurrence of imidazolinone-resistant weedy rice has not been documented in Malaysia.…”

Planta Daninha 2018; v36:e018182239 DILIPKUMAR, M. et al. Cross-resistance to imazapic and imazapyr in a weedy rice (Oryza sativa) biotype found in Malaysia 1 151103-PD-2016 (9 páginas) PROVA GRÁFICA ABSTRACT -The Clearfield ® rice production system is an effective management tool for weedy rice and other weeds in the direct-seeded rice culture. However, if farmers cultivating the Clearfield ® rice disregard stewardship recommendations, the industry could face a problem of herbicide-resistant weedy rice which would occur through the selection of outcrosses. This study aimed to confirm imidazolinoneresistant weedy rice in Malaysia. The resistant weedy rice (R-WR) was found to be 67 fold more resistant to OnDuty ® (premix of imazapic and imazapyr) than the susceptible weedy rice (S-WR) based on the GR 50 values (rate that causes 50% inhibition of shoot growth). The Clearfield ® rice cultivar was 32-fold more tolerant to OnDuty ® than the S-WR. Furthermore, the R-WR was 54 and 89 fold more resistant to imazapic and imazapyr applied separately than the S-WR, respectively. The Clearfield ® rice was 140-and 40-fold more tolerant to imazapic and imazapyr, respectively than the S-WR. The R-WR biotype was susceptible to non-selective herbicides glyphosate and glufosinate, as well as the selective graminicide quizalofop. Oxadiazon controlled the R-WR biotype, but pretilachlor was ineffective. The present study documented the first case of weedy rice that was cross-resistant to imazapic and imazapyr in Malaysian Clearfield ® rice field. Keywords:Clearfield ® system, imidazolinone-resistance, direct-seeded rice, ALS-inhibitor herbicide, ACCase-inhibitor herbicide. RESUMO -O sistema de produção de arroz
