15种叶面处理除草剂对6种中药材的药害症状观察

试验研究了芳氧苯氧丙酸类等7类15种除草剂对半夏、瓜蒌子、远志、黄芩、丹参、柴胡6种中药材的药害情况,筛选可以安全使用的除草剂及其施用用量。结果表明:在试验用量处理范围内,半夏使用骠马、收乐通、高效盖草能、精喹禾灵、喹禾灵的各用量和苯磺隆、烟嘧磺隆、阔世玛、乙羧氟草醚的1～4处理较为安全。瓜蒌子田施用1,2处理的阔世玛较为安全。远志和黄芩田施用骠马、收乐通、高效盖草能、精喹禾灵、喹禾灵的1～5处理较为安全。丹参田施用骠马、精喹禾灵、收乐通、高效盖草能、喹禾灵的各处理和苯磺隆、烟嘧磺隆、阔世玛的1,2处理均较为安全。柴胡田施用骠马、收乐通、高效盖草能、精喹禾灵、喹禾灵、苯磺隆、烟嘧磺隆、阔世玛、世玛的各用量及乙羧氟草醚的1～3处理较为安全。百草枯和草甘膦在供试药材田均不安全,不能施用。

Observation of Phytotoxicity Symptoms of 15 Kinds of Foliar Processing Herbicide to 6 Kinds of Chinese Herbal Medicine

The experiment studies on phytotoxicity situation of 15 kinds of herbicide to Pinellia ternata(Thunb.)Breit.,Semen Trichosanthis Kirilowii,Polygala tenuifolia Willd.,Scutellaria baicalensis Georgi,Salvia miltiorrhiza,root of Chinese thorowax.Through phytotoxicity symptoms observation,screening safe herbicides and concentration,the results show that: it was safe to use concentration 1～5 of fenoxaprop-P-ethyl,clethodim,haloxyfop-R-methyl,quizalofop-P-ethyl,quizalofop-ethyl,and concentration 1～4 of tribenuron-methyl,nicosulfuron,Sigma broad,nicosulfuron in Pinellia ternata(Thunb.) Breit.field.It was safe to use concentration 1～2 of Sigma broad in Semen Trichosanthis Kirilowii filed.It was safe to use concentration 1～5 of fenoxaprop-P-ethyl,clethodim,haloxyfop-R-methyl,quizalofop-P-ethyl,quizalofop-ethyl in Polygala tenuifolia Willd.and Scutellaria baicalensis Georgi field.It is safty to use concentration 1～5 of fenoxaprop-P-ethyl,clethodim,haloxyfop-R-methyl,quizalofop-P-ethyl,quizalofop-ethyl and concentration 1～2 of tribenuron-methyl,nicosulfuron,Sigma broad in Salvia miltiorrhiza field.It was safe to use concentration 1～5 of fenoxaprop-P-ethyl,clethodim,haloxyfop-R-methyl,quizalofop-P-ethyl,quizalofop-ethyl,tribenuron-methyl,nicosulfuron,Sigma,Sigma broad and concentration 1～3 of fluoroglycofen-ethyl in root of Chinese thorowax field.Paraquat and glyhosate were not safe in all the herbs fields in this study.
