Özet:

 The field experiments were carried out during 2017 and 2018 on commercial rice field in Kochani region to assess different POST-em herbicide programs for weed management in lowland flooded rice system in North Macedonia. In addition, herbicide selectivity and impact on rice grain yield were estimated. POST-em herbicide treatments were used in early-EPOST-em, mid-MPOST-em and late-LPOST-em rice growth stages BBCH 26; 29 and 32-34, respectively. Weed control varied among herbicide treatments, herbicide programs, and weeks after treatments WAT. All herbicides applied EPOST-em controlled Echinochloa crus-galli ECHCG and Scirpus maritumus SCMA 91-100. At MPOST-em treatment, herbicides showed control of ECHCG between 93 and 97. However, all herbicides applied LPOST-em controlled ECHCG 79-88. SCMA control was less than 88 and 85 with MPOST-em and LPOST-em treatments, respectively, perhaps as a consequence of progressive growth stage of SCMA BBCH 40. Control level of Cyperus rotundus CYPRO and Heteranthera reniformis HETRE was high in all POST-em treatments between 90-100, and 95-100, respectively. EPOST-em and MPOST-em application of any herbicide resulted no phytotoxicity to rice plants. LPOST-em treatments caused rice phytotoxicity by cyhalofop-butyl  penoxsulam, cyhalofop-buthyl  bentazon, and profoxidim  bentazon which were ranged from 8-20. Unlike rice yield at LPOST-em treatments was 6235 kg ha-1, all EPOST-em and MPOST-em used herbicides has impact in rice yield 6685 and 6610 kg ha-1, respectively which, but there were no statistically significant differences with the weed free control 6710 kg ha-1.
