Practice in Nursery Weed Control—Review and Meta-Analysis

Abstract

Weeds, as one of the biggest challenges in the nursery industry, have been controlled by various methods, such as chemical and non-chemical practices. Although these practices have been widely established and tested to control weeds, there is no systematic or meta-analysis review to provide quantitative weed control efficacy information of these practices. To provide a systematic understanding of weed control practices in nursery production, a visualization research trend, a systematic review, and a meta-analysis were conducted. A total of 267 relevant studies were included for the research trend and 83 were included in the meta-analysis. The results in this study showed that interests in nursery weed control have switched dramatically in the past 2–3 decades (1995–2021) from chemical dominant weed control to chemical coexistent with non-chemical techniques. Developing new management tactics and implementing diverse combinations of integrated weed management present the future trend for weed control. The systematic review results showed that chemical methods had the highest weed control efficacy, while non-chemical had the lowest on average, nonetheless, all three weed control practices (chemical, non-chemical, and combined) reduced the weed biomass and density significantly compared with when no strategy was employed. Weed control challenges could be the catalyst for the development of new non-chemical and integrated weed control techniques.

Design, Synthesis, and Biological Activity of Novel Phenyltriazolinone PPO Inhibitors Containing Five-Membered Heterocycles

“…Among them, chemical weeding still plays an important role in increasing crop yield. 4,5 For example, the use of herbicides with different modes of action can damage 90−99% of target weeds, which is also the most effective weed control method at present. However, the longterm use and abuse of herbicides will cause environmental pollution and pose potential risks to human health.…”

“…Pesticides play a vital role in this process. Among them, chemical weeding still plays an important role in increasing crop yield. , For example, the use of herbicides with different modes of action can damage 90–99% of target weeds, which is also the most effective weed control method at present. However, the long-term use and abuse of herbicides will cause environmental pollution and pose potential risks to human health. − At the same time, weed species that are resistant to herbicide-active ingredients are also increasing year by year, which has become a problem that cannot be ignored. − Therefore, it is necessary to develop new environmentally friendly herbicides with high activity, low dose, broad spectrum, and low toxicity.…”

Effect of Substrate Stratification Without Fine Pine Bark Particles on Growth of Common Nursery Weed Species and Container-grown Ornamental Species

“…This control over the substrate and fertilizer can be modified to control weeds. At present, cultural or nonchemical practices, such as mulching (Altland et al, 2016;Bartley et al, 2017;Marble et al, 2019;Richardson et al, 2008) and strategic fertilizer placement (Fain et al, 2003;Khamare et al, 2020;Saha et al, 2019) have garnered a renewed interest from researchers for developing weed management strategies that could be combined with herbicides to develop an integrated program (Yu and Marble, 2022).…”

Improving Pennsylvania Bittercress Weed Control Efficacy with Mulch and Herbicide in Containers

“…are cool-season annual weeds but grow year-round in nursery and greenhouse production conditions (Crone and Taylor, 1996). It is one of the most common and difficult weed species in container nurseries because it reproduces rapidly, transports easily, and may harbor pests (Cross and Skroch, 1992;Gallitano and Skroch, 1993;Yu and Marble, 2022). For example, Pennsylvania bittercress (Cardamine pensylvanica) can forcibly dehisce seeds up to 5 m and produce up to 5000 seeds that germinate within 2 weeks (Altland et al, 2016;Bachman and Whitwell, 1994;Vaughn et al, 2011).…”

“…However, the wide use of herbicides can create problems, such as herbicide-resistant weeds, environmental concerns, and economic losses (Briggs et al, 2002;Case and Mathers, 2006;Derr et al, 2020;Powles and Yu, 2010;Riley, 2003). Thus, nonchemical (mainly mulches) and integrated weed control method (herbicide 1 mulches) need to be further evaluated (Yu and Marble, 2022).…”
