精喹禾灵乳油 |
| 2. | Weed control effect of 17 . 5 benazolin amp; quizalofop - p - ethyl in rape fields
精喹禾灵乳油对油菜田杂草的控制作用 |
| 3. | It could be suggested that there be safety or no obvious toxicity to human health while sesame seed be consumed as a food for people if the herbicide be applied by the way of the filed trial
芝麻收获时，精喹禾灵在芝麻籽粒中的最终残留量低于0 . 02mg kg ( fa0颁布的精喹禾灵在花生中的mpl值) 。表明在芝麻作物上使用精喹禾灵对芝麻的食用是安全的。 |
| 4. | Three dominant strains of bacteria in clay soil were obtained by the screening experiments , which were acinetobacter icoaceticus - baumanni c0 / / ex ( nya2 ) , bacillus megaterium ( nyb ) and bacillus cereus ( nyb4 )
试验筛选了对精喹禾灵具有降解作用的优势菌株nya2 (鲍氏不动杆菌acinetobacterlcoaceticus - baumannicomplex ) 、 nyb1 (巨大芽孢杆菌bacillusmegaterium ) nyb4 (坚实芽孢杆菌bacilluscereus ) 3个。 |
| 5. | But the main metabolite of quizalofop - p - ethyl was decomposed much more slowly both in sesame plant and soil . the total residue of quizalofop - p - ethyl and its metabolite in sesame seeds after harvested was less than 0 . 02 mg / kg ( the recommended mrl of fao is 0 . 02 mg / kg in peanut seed )
田间残留试验结果显示：精喹禾灵在芝麻地土壤和芝麻植株中降解迅速，半衰期分别为1 . 35和1 . 18d ，其主要降解产物精喹禾灵丙酸在土壤和植株中的半衰期则较长。 |
| 6. | The results of microbial degradation of the herbicide showed that nyb1 and nyb4 had special ability to degrade the chemical from those bacteria tested in cultured media added a series volumes ( 5 - 20 % in total volume ) of bacteria suspension while the concentration of the herbicide at 50 mg / l in the media
在精喹禾灵添加浓度为50mg l的基础培养基中，分别加入液量为总体积5 20 nyb1和nyb4菌株的培养液，降解试验结果表明两种菌株均对精哇禾灵的降解作用明显。 |
| 7. | A analytical method was established for determining residues of quizalofop - p - ethyl ( ethyl ( rs ) - 2 - [ 4 - ( 6 - cororo - 2 - quinoxalinoxalinyloxy ) phenoxy ] propanoate ) and its main metabolite , by the high performance liquid chromatography under the condition optimized . it was applicable to determine residues of the herbicide and the metabolite in soil , sesame plant and sesame seed , and satisfied to meet the requirement of fortified recovery
在同一色谱分析条件下，可同步检测精喹禾灵及其代谢物，土壤、芝麻植株和芝麻籽粒样品进行方法添加回收率试验，均得到了较高的回收率及良好的重现性。 |
| 8. | It seems that micro - organism in soil played a very important role to decompose the herbicide with the results of microbial degradation , which the half - lifves of quizalofop - p - ethyl with a level of 50 mg / kg in clay and red soil were 9 . 9 and 15 . 7 days comparing with that in the two types of soil sterilized , 29 . 8 and 37 . 5 days , respectively
土壤微生物对精喹禾灵在土壤环境中的降解发挥了重要的作用。起始浓度为50mg kg的精喹禾灵在未灭菌、灭菌处理青紫泥中的降解半衰期( t1c2 )分别为9 . 9和29 . 8d ，在红壤中降解半衰期分别为15 . 7和37 . 5d 。 |
