Abstract

The objective of this greenhouse study was to evaluate tall fescue ( Festuca arundinacea ) seedling growth when seeded after herbicide application. Herbicide treatments included a nontreated control; 1.19 lb/acre 2,4-dichlorophenoxyacetic acid (2,4-D) + 0.32 lb/acre methylchlorophenoxypropionic acid (MCPP) + 0.32 lb/acre dicamba; 0.75 lb/acre quinclorac; and 0.06 lb/acre halosulfuron-methyl. Seeding was done at 0, 3, 7, or 14 days after herbicide application to soil media. Two identical experiments were conducted in the greenhouse: Expt. 1 seedling growth from January to March and Expt. 2 from May to July (temperatures higher). Seeding dates after herbicide application did not influence growth. Average dry shoot weight reductions and dry root weight reductions caused by postemergence herbicides were 2,4-D + MCPP + dicamba (33% shoot and 27% root in Expt. 2), quinclorac (30% shoot and 37% root in Expt. 2), and halosulfuron-methyl (51% shoot in Expt. 2; 81% root in Expts. 1 and 2). Although application of these herbicides before seeding in the field may result in no visual impact, they can impact seedling shoot and root growth, particularly under higher growth temperatures.

出苗期除草剂对高羊茅幼苗生长的影响
本温室研究的目的是评价除草剂施用后高羊茅(Festuca arundinacea)播种后的幼苗生长情况。除草剂处理包括一个未处理的对照;1.19磅/英亩2,4-二氯苯氧乙酸(2,4- d) + 0.32磅/英亩甲基氯苯氧丙酸(MCPP) + 0.32磅/英亩麦草畏;0.75磅/英亩;0.06磅/英亩的甲基卤磺隆。在土壤介质上施用除草剂后0,3,7或14天播种。在温室内进行了两个相同的实验:实验1在1月至3月进行幼苗生长,实验2在5月至7月(温度较高)进行幼苗生长。施用除草剂后的播种日期对生长没有影响。出苗后除草剂造成的平均干梢重和干根重减少分别为2,4- d + MCPP +麦草畏(33%地上部和27%根部)、喹乐灭(30%地上部和37%根部)和甲基氟磺隆(51%地上部);尽管在田间播种前施用这些除草剂可能不会造成视觉上的影响,但它们会影响幼苗的茎部和根系的生长,特别是在较高的生长温度下。
