Disease Progress

Table beet (Beta vulgaris ssp. vulgaris) production in New York is increasing for direct sale, use in value-added products, or processing. One of the most important diseases affecting table beet is cercospora leaf spot (CLS) caused by the fungus Cercospora beticola. CLS causes lesions on leaves that coalesce and leads to premature defoliation. The presence of CLS may cause buyer rejection at fresh markets. Defoliation from CLS may also result in crop loss because of the inability to harvest with top-pulling machinery. The susceptibility of popular table beet cultivars (Boldor, Detroit, Falcon, Merlin, Rhonda, Ruby Queen, and Touchstone Gold) to CLS was tested using C. beticola isolates representative of the New York population. Two trials were conducted by inoculating 6-week-old plants in the misting chamber. A small-plot replicated field trial was also conducted to examine horticultural characteristics of the cultivars. In the misting chamber trials, disease progress measured by the area under the disease progress stairs (AUDPS) was not significantly different between the red cultivars, Detroit and Ruby Queen, and was significantly higher in ‘Boldor’ than the other yellow cultivar Touchstone Gold. In the field trial, the number of CLS lesions per leaf at the final disease assessment and AUDPS were significantly lower in cultivar Ruby Queen than others and not significantly different between the yellow cultivars. The dry weight of roots was not significantly different among cultivars at first harvest (77 days after planting). At 112 days after planting, the dry weight of roots was significantly higher in cultivar Detroit than Rhonda and Boldor. Leaf blade length and the length:width ratio were cultivar-dependent, which may facilitate selection for specific fresh markets. Significant associations between canopy reflectance in the near infrared (IR) (830 nm), dry weight of foliage, and number of CLS lesions per leaf suggested that this technique may have utility for remote assessment of these variables in table beet research. Implications of these findings for the management of CLS in table beet are discussed.

Natural Gas Development

This article explores the recent history and significance of unconventional natural gas development in the Marcellus region of Pennsylvania, including a look at the state’s historical background on hydrocarbon production, the effect of political and social media campaigns against development activities and the outlook for the future. In consultation with industry and environmental groups, Pennsylvania’s state government has crafted rules and regulations allowing responsible development to proceed, helping industry secure and retain its licence to operate in the process. This success was further made possible by an early and robust public engagement strategy that refuted misinformation and provided proper context for both the benefits and challenges inherent in resource development. However, in neighbouring states like New York and Maryland, similar public strategies and campaigns in support of development were not as quickly assembled and mobilised. The contrasting histories (and final results) help provide a template of lessons learned for other areas considering shale development, including an opportunity to avoid the kinds of mistakes that have led to moratoria, bans or other restrictions on specific well stimulation technologies, such as hydraulic fracturing.

Aonidiella Aurantii

AbstractSemiochemical-based pest management programs have been increasingly used to provide environmentally friendly methods for the control of major insect pests. The efficacy of the mating disruption technique has been demonstrated for several moth pests. Unfortunately, not many experiments on mating disruption to control diaspididae species have been documented. In this work, biodegradable dispensers for mating disruption with increasing pheromone loads were used in order to study the potential of this technique for the control of Aonidiella aurantii Maskell. Field trial results demonstrated that dispensers loaded with 50 mg (a.i.) (20 g ha−1) and 100 mg (a.i.) (40 g ha−1) of sex pheromone were the most suitable, achieving significant reductions in male catches, compared to an untreated plot. In treated plots, virtually a 70% reduction in damage to fruit was recorded. Pheromone release profiles of all the dispensers were also studied under field conditions. We found that emission values >250 μg day−1 were the most suitable. This study suggests a new biodegradable dispenser capable of interfering with normal A. aurantii chemical communication. The use of mating disruption as a control method against A. aurantii is discussed.

The 19Th Century

The Lardner Vanuxem collection of minerals and fossils, lost since its sale in 1853-1854 to W. M. Stewart of Clarksville, Tennessee, has been rediscovered, along with a catalog of the collection. The collection is summarized in tabular form. The disposition of the specimens since the death of Vanuxem, in 1848, is also discussed. About five percent of the original 6,000-specimen mineral collection still exists at Southwestern University at Memphis. The Vanuxem collection catalog, reprinted by W. M. Stewart circa 1855, indicated a comprehensive collection of the minerals known in the first half of the 19th century. The Vanuxem fossil collection contained some 16,000 sepcimens, most of which were from the Lower Paleozoic (Potsdam Sandstone, Medina Sandstone, Marcellus Shale, and many Trentonianage formations) of New York State. The collection was organized later by W. M. Stewart on the basis of geologic periods. Ordovician, Silurian, Devonian, and Tertiary fossils are dominant. No trace of the Vanuxem fossil collection exists today, although it was still in use in 1923 by students at Southwestern Presbyterian University, Clarksville, Tennessee.

Farm Type

We study farm real estate values in the Barnett shale (Texas) and the northeastern part of the Marcellus shale (Pennsylvania and New York). We find that shale gas development caused appreciation in real estate values in both areas but the effect was much larger for the Marcellus, suggesting broader ownership of oil and gas rights by surface owners. In both regions, the greatest appreciation occurred when land was leased for drilling, not when drilling and production boomed. We find evidence that effects vary by farm type, which may reflect correlation between farm type and ownership of oil and gas rights.
