摘要

•白毛茛(Aloysia gratissima)是德克萨斯州南部的一种原生灌木,由于形成单一种植的林分,通常需要集约化管理,已成为牧场的滋扰。白桦属干旱落叶植物(即,对水分胁迫的落叶反应),这限制了叶面除草剂应用的传统机会窗口。•2020年,一种新的吡啶酸类除草剂(Invora;氨基环吡草胺 + 三氯吡啶[ACP + t1:2])能够对某些再生木本物种提供高水平的控制,已被批准用于牧场。我们的田间试验表明,在处理两年后,Invora作为单株(IPT,死亡率 = 100%)和不分季节的叶面撒播(BC,死亡率 = 98.6%)均具有较高的控制水平(P = 0.29,α = 0.05)。•我们还发现,当在化学混合物中添加至少2.5%的表面活性剂时,其他常用除草剂叶面状施用于休眠灌木(IPT死亡率 = 99.7%,BC死亡率 = 83.5%)时可以非常有效。•实验室测试表明,白刷种群之间每年产生的可活种子百分比差异很大(6%-49%),为处理后的种群招募策略提供了见解。

An assessment of chemical control options for whitebrush (Aloysia gratissima) in South Texas
  • Whitebrush (Aloysia gratissima) is a native shrub in South Texas that has become a nuisance on rangelands by forming monoculture stands often requiring intensive management. Whitebrush is drought deciduous (i.e., defoliation in response to moisture stress), which limits the traditional window of opportunity for foliar herbicide applications.
  • In 2020, a new herbicide in the picolinic acid family (Invora; aminocyclopyrachlor + triclopyr [ACP + T 1:2]) capable of offering high levels of control for select resprouting woody species was approved for use in rangelands. Our field trials demonstrated Invora provided high levels of control when applied as individual plant (IPT, mortality = 100%) and broadcast (BC, mortality = 98.6%) foliar treatments regardless of season (P = 0.29, α = 0.05) two years after treatment.
  • We also found foliar-like applications of other commonly used herbicides can be highly effective when applied to dormant shrubs (IPT mortality = 99.7%, BC mortality = 83.5%) with at least 2.5% surfactant in the chemical mix.
  • Laboratory testing indicated high variation in the percentage of viable seed produced annually between whitebrush populations (6%–49%), providing insight into population recruitment strategies post-treatment.
