Ventenata [Ventenata dubia (Leers) Cross] is a winter annual grass relatively new to the inland Pacific Northwest that is capable of displacing desired vegetation. Indaziflam was evaluated for the management of V. dubia on two Conservation Reserve Program (CRP) sites near Moscow, ID, and Pullman, WA. While perennial grasses were dormant, applications of indaziflam in mixture with various herbicides were made in spring 2016. Treatment effects were evaluated for 2 yr by visual assessments of community composition and canopy cover of V. dubia and other non-weedy species (assessments occurred 3 to 6 mo after treatment, depending on location) and by representative cover class assessments. Biomass samples of all plant species were collected in the summer of 2017. Reduced V. dubia cover was observed in 2016, except when glyphosate was used alone. In 2017 indaziflam applied alone or in mixture with rimsulfuron effectively controlled V. dubia with minimal impact on desirable vegetation. Plant biomass from nontreated plots averaged 40 g m−2 for V. dubia and 100 to 179 g m−2 for perennial grasses. Plant biomass averaged <11 g m−2 for V. dubia and 371 to 490 g m−2 for perennial grasses when indaziflam at 102 g ai ha−1 plus glyphosate at 474 g ai ha−1 was applied. Smooth brome (Bromus inermis Leyss.) biomass was positively associated with the reduction of V. dubia, and there was a decrease in diversity associated with the removal of V. dubia through effective treatments. Indaziflam is an effective tool for the management of V. dubia in perennial grass stands, and spring applications of indaziflam should be in mixture with herbicides with POST activity.

用吲达济菌管理西北太平洋内陆地区的 Ventenata dubia

文特纳塔 [狐臭(Leers) Cross] 是一种相对较新的冬季一年生草，对于内陆太平洋西北地区来说，能够取代所需的植被。Indaziflam 被评估用于管理五、杜比亚在爱达荷州莫斯科和华盛顿州普尔曼附近的两个自然保护区计划 (CRP) 站点上。虽然多年生草本处于休眠状态，但在 2016 年春季将吲达西林与各种除草剂混合施用。通过对群落组成和冠层覆盖的目测评估，对 2 年的处理效果进行了评估。五、杜比亚和其他非杂草物种（评估发生在处理后 3 到 6 个月，取决于位置）和具有代表性的覆盖类评估。2017 年夏天收集了所有植物物种的生物质样本。 减少五、杜比亚2016 年观察到覆盖，除非单独使用草甘膦。2017年吲达西林单用或与氟嘧磺隆合用得到有效控制五、杜比亚对理想植被的影响最小。未经处理的地块的植物生物量平均为 40 克-2为了五、杜比亚和 100 到 179 克-2为多年生草。植物生物量平均 <11 gm-2为了五、杜比亚和 371 到 490 克-2102 g ai ha 时用于多年生草类-1加草甘膦 474 g ai ha-1被应用。光滑的雀麦 (无芒雀麦Leyss.) 生物量与减少五、杜比亚，并且与去除五、杜比亚通过有效的治疗。Indaziflam 是一种有效的治疗方法五、杜比亚在多年生草丛中，春季施用吲达西林应与具有 POST 活性的除草剂混合使用。
