夏型一年生杂草危害能限制寒地型草坪草在春天或夏天建坪的成功。Fenoxaprop是一种对夏型一年生杂草有明显作用,而对成熟的多年生黑麦草或苇状羊茅草坪安全的芽后除草剂。大量的研究已证实了多年生黑麦草和苇状羊茅幼苗对Fenoxaprop具有一定的抗性。“Citation”和“palmer”多年生黑麦草以及“Olympic”和“Houndog”苇状羊茅分别播种于Chillum砂壤土(细砂、混合mesic Typl Hapluluts)上或Beltsrille砂壤土(细壤、混合mesic Typic Fragiudults)上,通过两年多的试验表明,在六种喷撒日期中仅有一日,喷撒Fenozaprop时才能引起以上二种草坪种的幼苗变黄。用0.09～0.28千克/公顷Fenoxaprop处理后的草坪,我们没有见到草坪质量降低或其它明显不利现象的发生,以0.09千克/公顷的量喷撒Fenoxaprop在2～4分蘗期才能有效地防除无毛马唐,在此喷撒量和日期中,单独喷撒Fenoxaprop均能降低无毛马唐的竞争,并能获得好(89％)到极好(99％)的草坪草覆盖度。
Summer annual weed hazards can limit the success of winter-type turfgrasses in spring or summer. Fenoxaprop is a safe post-emergent herbicide for mature summer perennial rye or reed fescue lawns that have a significant effect on summer-type annual weeds. Numerous studies have confirmed that perennial ryegrass and tall fescue seedlings have some resistance to Fenoxaprop. The “Citation” and “palmer” perennial ryegrass and the “Olympic” and “Houndog” tall fescue were sown on Chillum sandy soil (mixed mesic Typl Hapluluts) or Beltsrille sandy loam (meshed, mixed mesic Typic Fragiudults ), Over two years of testing showed that seedling of the above two turfgrass species was yellowed on only one day out of six spray dates when Fenozaprop was sprayed. We did not see a decrease in turfgrass quality or other significant detrimental effects with 0.09-0.28 kg Fenoxaprop-treated turf. Fenoxaprop was sprayed at 0.09 kg / ha at 2-4 tillering stages to effectively prevent hair loss Cinnamon, Fenoxaprop sprayed alone reduced the competition for the hairless crabgrass and achieved good (89%) to excellent (99%) turf coverage on this amount and date of spray.
