Over Time

Non-native invasive plants can establish in natural areas, where they can be ecologically damaging and costly to manage. Like cultivated plants, invasive plants can experience a relatively disease-free period upon introduction and accumulate pathogens over time. Diseases of invasive plant populations are infrequently studied compared to diseases of agriculture, forestry, and even native plant populations. We evaluated similarities and differences in the processes that are likely to affect pathogen accumulation and disease in invasive plants compared to cultivated plants, which are the dominant focus of the field of plant pathology. Invasive plants experience more genetic, biotic, and abiotic variation across space and over time than cultivated plants, which is expected to stabilize the ecological and evolutionary dynamics of interactions with pathogens and possibly weaken the efficacy of infectious disease in their control. Although disease is expected to be context dependent, the widespread distribution of invasive plants makes them important pathogen reservoirs. Research on invasive plant diseases can both protect crops and help manage invasive plant populations.

Inappropriate Use

The inappropriate use of herbicides has increased the resistance of weeds; thus, the study of allelopathy becomes of paramount importance. The ability of certain plants to interfere with the metabolism of others by means of substances released into the environment, either by their aerial or roots system, becomes an alternative to combat invasive plants, dispensing with or reducing the use of herbicides. The objective of this work was to evaluate the plant species most sensitive to the allelopathic potential of aqueous extracts. One of the plant species studied was lettuce because it had a rapid response potential, thus showing the benefits obtained through allelopathy.

The Impact

In order to evaluate the allelopathic potential of an exotic invasive weed,Parthenium hysterophorusL., the effect of different concentrations of aqueous extracts (5%, 25%, 50%, 75% and 100%) prepared from leaves ofP. hysterophoruswere studied on the seed germination and seedling shoot growth of two common native herbs,Plantago asiaticaL. andYoungia japonica(L.) DC., through laboratory bioassays. The aqueous leaf extracts at the concentrations of 25%, 75% and 100% significantly inhibited the seed germination and seedling shoot growth of two target species. There was complete failure of seed germination ofY. japonicain 75% and 100% aqueous leaf extracts. The inhibitory effect increased with increasing extract concentration. These results suggested that allelopathy may play a role in the impact ofP. hysterophorusinvasion on native plant recruitment of invaded communities in southern China.

The ecosystems of the United States face numerous threats to sustainability arising from the introduction and proliferation of non-native, invasive plants and animals. One example is that of Asian carp, a species of invasive fish that is devastating native ecosystems in some inland US waterways. Current concerns center on the migration of Asian carp into the Great Lakes and how that could be particularly detrimental to the ecosystems and natural stability of the area. This paper examines the policy alternatives for halting the advance of Asian carp before they reach the Great Lakes, and recommends that electric barriers be used as the primary means of deterrent. However, such barriers are not a universally-applicable solution, and further research on securing US waterways from the Asian carp threat is required.

Circular 1204-Sp, an 8-page illustrated  publication by K.A. Langeland, is the Spanish language version of Circular 1204, “Help Protect Florida’s Natural Areas from Non-Native Invasive Plants.” It describes the problem of weeds in natural areas, federal and state laws regulating plants, official lists of non-native invasive species. It encourages Florida residents to learn to identify invasive plants and to remove them from their property. Includes references. Published by the UF Department of Agronomy, February 2008.

The Relationship

Plants have been introduced into the United States intentionally as well as unintentionally as seeds and weeds. Technological advances, a mobile society, and our curiosity and desire to improve our landscapes have led to an ever-increasing invasive movement. These alien plants can jeopardize native populations, alter ecosystems, alter fire and water regimes, change the nutrient status, modify habitats, and cause significant economic harm. Today's public is unaware of the danger some non-native plants species pose to natural areas, thereby contributing to the lack of control for non-native invasive plants. This study looked at the knowledge and attitudes of Texas Master Gardeners as related to invasive species commonly used in landscaping. A web survey was made available to all Texas Master Gardeners that included pictures of plants along with their common and scientific names. Participants were asked to identify which they thought were invasive and contribute information regarding their knowledge of non-native invasive plants. Each of the invasive plants shown is on both the federal and the Texas Invasive Plant lists. Inquires were made concerning the occurrence of these plants in the participants' personal landscape and communities and their perceptions of each plant as an invasive threat. The purpose of the study is to determine if a relationship exists between knowledge, attitudes and perceptions of the participant and the occurrence of non-native invasive plants in the landscape. The results of this study will help determine factors that contribute to the lack of control for non-native invasive plants.
