| Abstract | Sawtooth coriander (Eryngium foetidum L.) is one of the most important export herbs of Thailand. Despite weeds being the major problem in its cultivation system, effective herbicide control procedure has not yet been developed. The objective of this research wasto investigate the efficacy and suitability of 11 pre-emergence herbicides in sawtoothCoriander cultivation. The study was carried out from January 2017 to April 2018 in afarmer's field in Nakhon Sawan province. The 11 pre-emergence herbicides investigatedwere metribuzin, flumioxazin, oxyfluorfen, oxadiazon, clomazone, acetochlor, butachlor,s-metolachlor, alachlor sulfentrazone and pendimethalin at the application rates of 70, 5,37.6, 75, 38.4, 200, 240, 96, 288, 22.4 and 198 g ai/rai respectively. They were compared withnon-treated control and hand weeding. Results showed that metribuzin, flumioxazin,clomazone, acetochlor, butachlor, s-metolachlor and alachlor were toxic to sawtoothcoriander. The sawtooth coriander could not grow in the metribuzin and acetochlor treatedplots. In addition, clomazone caused the sawtooth coriander to die at 15 days aftergermination. Only, oxyfluorfen, oxadiazon and pendimethalin were less or non-toxic to thecrop with effective weed control up to 30 days after application, resulting in higher yieldthan other herbicides. When costs of weed control among treatments were compared,results showed that oxyfluorfen, oxadiazon, and pendimethalin costed 4 7 times less thanhand weeding. |
