发帖数: 27354 | 1 我家草坪有很多crabgrass, 现在已经通过费劲九牛二虎之力基本达到人工去除。虽然
以后还有后患，但要及时拔出，恐怕比刚刚过去的劳动量小得多。
但是，我才刚刚发觉，有一种草很细长很壮实，贴着地面扩张，夏天涨势特别旺盛。上
网查看后知道叫做 creeping bentgrass. 请问你们有手工拔除creeping bentgrass的
经验吗？估计这个是多年生（只是冬天枯黄，春天返青很慢，所以不好看），很难弄。 |

发帖数: 268 | 2 春季发现草坪有几块creeping bentgrass 当时没太在意
现在越来越多 基本有整个 草坪的50% 左右了 而且东一块西一块分布很杂乱
除了roundup还有其他什么可以杀bentgrass的吗？ tenacity据说效果不行杀不死？ |

发帖数: 1783 | 4 你说的creeping bentgrass 可能是 Nimblewill. 在北美广大地区常见杂草，很难根除。
你可以考虑用Syngenta 的 tenacity。 Tenacity 见效慢，会把草坪漂泊。 另外某些
州禁止自己喷洒 tenacity。 Syngenta也不推荐一般家庭用户使用，主要是使用量难于
控制。 |

发帖数: 4125 | 5 You should only cut low in summer if you have warm season grass. You should
cut high if you have cool season grass during hot summer (especially for
those don't like to water a lot), you can cut lower again in fall.
Common cool season grass are Bluegrass, Bentgrass, Ryegrasses and Fescues. |

发帖数: 7142 | 10 不好意思，我没能认出这个是什么草来。我不熟悉这种草。
我怀疑是 bentgrass, 我在别人家的草坪有见过类似的杂草，
没有确认。
也有可能就是 Tall Fescue, 但是你拔那几根不是很典型。
Tall Fescue 一般叶子出在比较低的地方，这个好像很高的
样子。所以我不知道。 |

发帖数: 11909 | 13 Google了一下，应该就是啊，原来这种bugs对草地有害呀，我经常看到一窝一窝的草地
上飞来飞去，看来现在危害不大， 但到7月破坏就会显示出来
Damage
Hairy chinch bugs prefer feeding on red fescues, perennial ryegrass,
bentgrass, and Kentucky bluegrass. Chinch bug infestations frequently occur
in turfgrass with thick thatch that is exposed to full sunlight during
periods of hot, dry weather. Chinch bug damage is often less noticeable
during the spring and early summer. Damage frequently appears from early
July through late August when the insects are actively feed... 阅读全帖 |

发帖数: 27354 | 14 的确难分辨。我还是觉得是creeping bent grass ，横长，有些很长，根很壮实不易拉
断，叶子小。虽然不知道会不会搞错。这个东西目前毫无开花接种迹象，或许就靠根的
横长来繁殖。我搜索到的Bermuda grass 会接种子，而Nimblewill又不够像。
我以后发个图上来。草的图貌似很难拍清楚。 |
