“…Increased tiller production might be due to the fact that effective control of weeds by herbicides at initial stage and better environment for crop created by hand weeding at later stages by way of reducing crop-weed competition. These findings are in line with Deivasigamani (2016) [3] and Yadav et al (2019) [21] . Unweeded control resulted in higher nutrient removal by weeds and increased weed dry matter production.…”

Nadu during Late samba season (September, 2022 -February, 2023 in a randomized block design with nine treatments and replicated thrice. Among the different treatments, Stale seedbed technique fb Hand weeding which is statistically on par with Stale seedbed technique fb Triafamone 20% + ethoxysulfuron 10% WG @ 220 g ha -1 at 8 DAT recorded the lower weed count, weed dry matter production and the higher weed control index favouring higher growth attributes and grain yield of rice while maximum nutrient uptake was recorded under weed free check. Higher plant height, dry matter production and higher grain yield were recorded under the treatment Stale seedbed technique fb one hand weeding at 25 DAT practice might be due to maintenance of weed free environment, particularly throughout vital growth stages of crop, cut back crop weed competition helped in higher growth and development leading to higher grain yield.

“…Untreated control (T1) resulted in the significantly (P<0.05) highest density of weeds at 42 DAA during both the years of study. These findings were in agreement with Deivasigamani [11], Deivasigamani [12] and Murali Arthanari [10].…”

A field experiment was conducted for two consecutive years (2017 -18 and 2018-19) at Agricultural Research Station, Jangamaheswarapuram, Guntur Dist. Andhra Pradesh, India. The experiment consisted of nine treatments laid out in a complete randomized block design with four replications. The results revealed that Triafamone18.52 SC doses at a rate of 100 g a.i. ha-1 (T5) and 50 g a.i. ha-1 (T4) at the 2-3 leaf stage of weed were effective in controlling all the weeds and recorded significantly (P<0.05) lesserdry weight of weeds over the control during the study.

“…Further, applied herbicide had role reducing the accumulation of translocation of synthates to the sink area (Kumar and Ladha 2011). Deivasigamani (2016) found that application of triafamone + ethoxy sulfuron recorded lower weed density and dry matter at 42 days after application in direct seeded rice.…”

Field experiments were conducted during Rabi 2018-19 (September to January) and Kharif 2019 (May to September). Medium duration rice cv. CO(R) 51 was used as a test variety at Tamil Nadu Agricultural University, Coimbatore, India to study the effect of Triafamone on broad spectrum weed control in transplanted rice. Triafamone was applied at two times. First set of treatments (30, 40,50 and 100 g/ha) applied two to three leaf stage of weeds and second set treatments imposed (30, 40,50 and 100 g/ha) at three days after transplanting of the rice crop. These treatments were compared with Pyrazosulfuron ethy 10% WP @ 15 g/ha, Pretilachlor 5% EC @ 750 g/ha, hand weeding @ 20 and 40 days after transplanting and unweeded control. The major grasses were Echinochloa crus-galli (L.) and E. colonum (L.) while the sedge weed included Cyperus nutans (L.). Among the broad leaved weeds Eclipta alba (L.) and Bergia ammanioides were the dominant species. In both the seasons of the study, lesser population of grass was recorded with the pre and early post emergence application of triafamone herbicide 40 g a.i. ha-1 (1.41 and 1.41 per m-2 at 28 and 42 DAA for both the seasons respectively) and it was closely followed by application of triafamone herbicide 50 g a.i. ha-1 and application of PE Pretilachlor at 0.75 kg a.i. ha-1 and EPOE Pyrazosulfuron ethyl at 15 g a.i. ha-1. The same trend was observed for broad leaved weeds and their weed dry weights. Application of triafamone herbicide at 40 g a.i. ha-1 as pre emergence and early post emergence application recorded highest weed control efficiency of 100, 97.7 and 99.6 % and 97.8% at 42 DAA during both years of experimentation and also resulted in higher grain yield (8052 and 8182 kg ha-1 during rabi 2018-19 and 9018, 9175 kg ha-1 during Kharif 2019). Further, it is noticed that, there was no residual toxicity of herbicide to the succeeding crops. Hence, application of Triafamone 40 g a.i. ha-1 either pre or early post emergence herbicide has higher productivity and no residues in transplanted rice ecosystem. Key words: Triafamone, efficacy, weeds and transplanted rice ecosystem
