“…When utilizing fungicides in gardens and public spaces, application visibility, fungicide drift, and the potential for exposure of the public to fungicide residue also must be considered. Fourth, some non-chemical alternatives, including biological control agents (Kong 2019; Kong and Hong 2017;Kong and Hong 2020;Yang and Hong 2017;Yang and Hong 2018a) and reduced risk products (Samavat and Asl 2019;Samavat et al 2020) are emerging, but…”

Rapid Decline of Calonectria pseudonaviculata Soil Population in Selected Gardens Across the United States

Calonectria pseudonaviculata (Cps) poses a serious threat to boxwood, an iconic landscape plant in American and European gardens. Under the mild climatic conditions of the United Kingdom, Cps remained recoverable in infected leaf debris after being left on the soil surface or buried for 5 years. The primary objective of this study was to determine how this fungus may weather the warmer summers and colder winters in the United States by sampling and baiting soil with boxwood cuttings, and by on-site testing with sentinel plants. Soil sampling started in a Virginia garden in January 2016 and was extended to California, Illinois, New York, and South Carolina in early summer of 2017 through late fall of 2018. The Cps soil population as measured by the percentage of infected bait leaves declined sharply within the first year of blighted boxwood removal and fell to an almost undetectable level at the end of this study. To validate these baiting results, the Virginia garden was tested on-site four times with container-grown boxwood plants while the South Carolina garden and three New York gardens were tested once. Each test began with sentinel plants set out for field exposure, followed by evaluation(s) on-site then in the laboratory, after plants were retrieved from these gardens and incubated under conducive environments for 2 weeks. Cps was not observed on any sentinel boxwood plant on-site or in the laboratory with one exception. These observations indicate that Cps did not survive in the United States garden soil over time as well as it did in the United Kingdom. These results have important practical implications while challenging the notion that fungi producing microsclerotia will always survive in the soil for many years.

Boxwood (Buxus spp.) is the most commonly cultivated woody ornamental shrubs in landscape settings and nursery production. Boxwood is grown for its attractive evergreen foliage and versatility in both formal and informal gardens. Meeting the high demand for boxwood plants worldwide has become challenging in recent years as the boxwood industry has been negatively impacted by a growing number of serious diseases and arthropod pests. Globally, the most common arthropods of concern are boxwood leafminer (Monarthropalpus flavus, Diptera: Cecidomyiidae), boxwood psyllid (Psylla buxi; Hemiptera; Psyllidae), Eurytetranychus buxi (Acari: Tetranychidae) and the invasive moth, Cydalima perspectalis (Lepidoptera: Crambidae). Moreover, major diseases of boxwood include boxwood blight (Calonectria pseudonaviculata, Hypocreales: Nectriaceae), Volutella blight (Pseudonectria buxi, Hypocreales: Nectriaceae), and Phytophthora root and crown rot (Phytophthora spp., Peronosporales: Peronosporaceae). These pests and diseases can lead to significant economic losses to growers and can decimate plants in landscape settings. Here we have reviewed recent research advances focused on the description and management of boxwood arthropod pests and diseases. Boxwood arthropod pests and diseases can be managed by implementing integrated arthropod pest and disease management strategies such as sanitary and cultural practices, genetic resistant cultivars, biological and chemical control methods. This information is provided to aid nursery producers, landscape industry professionals, and other stakeholders in developing integrated arthropod pest and disease management plans for boxwood.

The use of essential oils and extracts of medicinal plants is one of the environmentally friendly methods in the management of plant diseases caused by fungi and bacteria. The antimicrobial effect of essential oils and extracts of various medicinal plants such as thyme, cloves, savory, garlic, licorice and fennel has been proven and their active ingredient has also been identified. Based on these studies, the possibility of introducing, formulating and using essential oils and extracts of medicinal plants or any of their components with antimicrobial properties, as an alternative method of using chemical toxins in the management of fungal and bacterial diseases of plants can be provided.
