“…Furthermore, cyhalofop‐butyl and penoxsulam resistance were confirmed in E. oryzicola that was collected from the Gimje region, which is ~125 km away from the Seosan region in Chungnam Province, South Korea (Park et al ). More recently, flazasulfuron and imazaquin resistance were reported in E. crus‐galli in the same region as E. oryzicola described above (Won et al ). However, there is no further study of the ALS inhibitor resistance mechanisms of Korean Echinochloa spp.…”

This study was conducted to evaluate the cross‐resistance of acetolactate synthase (ALS) inhibitors with different chemistries, specifically azimsulfuron (sulfonylurea), penoxsulam (triazolopyrimidine sulfonanilide) and bispyribac‐sodium (pyrimidinyl thio benzoate), in Echinochloa oryzicola and Echinochloa crus‐galli that had been collected in South Korea and to investigate their herbicide resistance mechanism. Both Echinochloa spp. showed cross‐resistance to the ALS inhibitors belonging to the above three different chemistries. In a whole plant assay with herbicides alone, the resistant/susceptible ratios for azimsulfuron, penoxsulam and bispyribac‐sodium were 12.6, 28.1 and 1.9 in E. oryzicola and 21.1, 13.7 and 1.8 in E. crus‐galli, respectively. An in vitro ALS enzyme assay with herbicides showed that the I 50‐values of the resistant accessions were approximately two‐to‐three times higher than the susceptible accessions, with no statistical difference, suggesting that the difference in ALS sensitivity cannot explain ALS inhibitor resistance in Echinochloa spp. for azimsulfuron, penoxsulam and bispyribac‐sodium. A whole plant assay with fenitrothion showed that the GR 50‐values significantly decreased in both the resistant E. oryzicola and E. crus‐galli accessions when azimsulfuron, penoxsulam and bispyribac‐sodium were applied with the P450 inhibitor, while no significant decrease was observed in the susceptible accessions when the P450 inhibitor was used. Thus, these results suggest that ALS inhibitor cross‐resistance for azimsulfuron, penoxsulam and bispyribac‐sodium is related to enhanced herbicide metabolism.

“…Qing-ya et al (2004) tolerance species to pretilachlor in China. In Korea, barnyard grass was resistant to azimsulfuron, bensulfuron-methyl, bispyribac-sodium, cyhalofop-butyl, fenoxaprop-P-ethyl, flazasulfuron, halosulfuron-methyl, imazosulfuron, metamifop, pyrazosulfuron-ethyl, and pyribimenzinobimac-methyl (Won et al, 2014;Heap, 2020). Changes from traditional transplanting to direct-seeding culture from the 1990s onwards in Vietnam resulted in significant changes in weed control strategies, with greater reliance on herbicides.…”

Barnyard grass (Echinochloa crus-galli (L.) Beauv.) is a major weed widely distributed across the world and causes serious damage to rice production. Yield loss due to barnyard grass was estimated at about 7 to 27% in Vietnam. This study aimed to investigate the rice production, weed impacts, herbicide usage and herbicide resistance in the Central Region of Vietnam. A survey of farmers producing rice and yield loss due to weeds conducted in Central Region showed that men mainly educated at primary and secondary schools was the main labour source in rice production. The density of barnyard grass and weed index was 13.9 plants m -2 and 14.1%, respectively, in the fields that weeds had regrown after application of herbicide. Screening in the greenhouse indicated that resistance to pretilachlor was found in populations of barnyard grass in Thua Thien Hue. The field trial indicated that a concentration of pretilachlor at the recommended rate (0.3 kg a.i. ha -1 ) was no longer effective in controlling barnyard grass. This indicates the resistance in populations of barnyard grass in Thua Thien Hue to pretilachlor in the field. The current result is the first report of resistance of barnyard grass to chloroacetamide in Vietnam.

Aprilia, N.A. et al. : Resistensi gulma Echinochloa crusss-galli terhadap herbisida berbahan aktif Metamifop di areal persawahan Sulawesi Selatan Aprilia, N.A. • D. Kurniadie • U. Umiyati Resistensi gulma Echinochloa crusss-galli terhadap herbisida berbahan aktif Metamifop di areal persawahan Sulawesi Selatan Sari Barnyardgrass [Echinochloa cruss-galli (L.) P. Beauv.] diakui sebagai gulma paling bermasalah di areal persawahan Provinsi Sulawesi Selatan, Indonesia. Herbisida metamifop sudah lama digunakan untuk mengendalikan gulma tersebut pada areal pertanaman padi sawah di Sulawesi Selatan dengan intensitas aplikasi yang cukup tinggi. Hal tersebut menimbulkan E. cruss-galli yang sulit dikendalikan dan diperkirakan resisten terhadap herbisida metamifop. Namun demikian, kasus resistensi gulma terhadap herbisida metamifop di Indonesia belum banyak dilaporkan dan diteliti. Penelitian ini bertujuan untuk mengetahui (1) adanya resistensi gulma E. cruss-galli terhadap metamifop, (2) tingkat resistensi yang terjadi pada gulma E. cruss-galli terhadap metamifop.
