- Title:
- Analysis of the Different Herbicides on Field Efficacy of Stevia rebaudiana
- Keywords:
- Stevia rebaudiana; herbicide; safety; control effect
- 文献标志码:
- A
- 摘要:
- 为促进农民增产增收,试验以6种不同处理的除草剂对4~5叶期的甜叶菊进行处理,供试药剂使用剂量顺序为高效盖草能10.8% EC 525 mL·hm-2-,精稳杀得15% EC 900 mL·hm-2-,精禾草克5% EC 1 050 mL·hm-2--,拿捕净12.5% EC 1 350 mL·hm-2-,拿捕净12.5% EC 1 500 mL·hm-2-,拿捕净12.5% EC 1 650 mL·hm-2--。在田间常规栽培情况下,不同除草剂对甜叶菊生长期的安全性及防治效果的研究。结果表明:施药后14和45 d,处理5(拿捕净12.5% EC用药浓度为1 350 mL·hm-2-)对靶标杂草防治效果均为最佳,而且对甜叶菊具有安全性。本试验表明,拿捕净12.5% EC对甜叶菊种植田一年生禾本科杂草及阔叶杂草的具有防治效果,对甜叶菊安全,最佳使用剂量为1 350 mL·hm-2-,杀草谱为藜、稗草、狗尾草、野燕麦、牛筋草、刺儿菜等。
- Abstract:
- In order to promote farmers to increase yield and income,six herbicides with different treatments were used to treat Stevia rebaudiana at 4-5 leaf stage,the dosage of the tested herbicides were haloxyfop-R-methyl 10.8% EC 525 mL·hm-2-,fluazifop-p-butyl 15% EC 900 mL·hm-2-,quizalofop-p-ethyl 5% EC 1 050 mL·hm-2-,and sethoxydim 12.5% EC 1 350 mL·hm-2-,sethoxydim 12.5% EC 1 500 mL·hm-2-,sethoxydim 12.5% EC 1 650- mL·hm-2-.Under the condition of conventional cultivation in the field,the results of the safety and control effect of different herbicides on the growth period of Stevia rebaudiana showed that treatment 5 (sethoxydim 12.5% EC concentration was 1 350 mL·hm-2-) had the best control effect on target weeds 14 days after application and 45 days after application,and it was also safe for Stevia rebaudiana.The experiment showed that sethoxydim 12.5% EC had control effect on annual grasses and broad-leaved weeds in Stevia rebaudiara plantation field,and was safe for stevia.The optimum dosage 1 350 mL·hm-2-.The herbicidal spectrum was as follows:Chenopodium album Linn.,Echinochia crusgali(Linn.)Beaur.,Setaria viridis(Linn.)Beauv.,Avena fatua Linn.,Eleusine indica(Linn.)Gaerth.,Cirsium setosum(Wild.)MB.etc.
