“…Competition from international growers was a concern because growers in the USA will likely have to deal with increasingly stringent environmentally-based water regulations, whereas environmental regulations for growers in other countries (likely to export plant material to the USA) may not be as stringent. Therefore, compliance costs may be lower outside the USA and result in a competitive advantage [26]. Hall et al [27] noted that grower perception of the stringency of environmental regulations in states within the USA, did not impact adoption of BMPs to meet environmental regulations, growers in "less strict" states were as likely to adopt BMPs as those in "strict" states.…”

Nursery, floriculture, and propagation production accounted for 79% ($13.3 Billion) of 2017 ornamental specialty crop production in the United States. Access to high quality water sources is increasingly limited for irrigating these economically significant crops. Given the production, environmental, and economic issues associated with the use of water—including recycled, reclaimed, surface, and ground water—it is critical to develop sustainable runoff, containment, and remediation technologies, and to identify alternative sources of water. To better understand current practices and future water-related needs as perceived by grower stakeholders, an online survey was distributed nationally and five in-depth round table discussion sessions were conducted at the Mid-Atlantic Nursery Trade Show, Gulf States Horticultural Expo, California Grown Show, AmericanHort’s Cultivate, and the Farwest Show with a total of 36 individual industry participants. A team of research and extension specialists facilitated by a Specialty Crops Research Initiative Planning Grant (NIFA Project # 2011-51181-30633) analyzed and concisely summarized the results from the survey and the round table discussions. Research priorities related to water management identified by stakeholders revolved around six themes: (1) recycled water infrastructure and management; (2) contaminants; (3) plant health and water quality; (4) water treatment technologies; (5) competing and complementary water uses; (6) societal perception of agricultural water use.

“…Container production is a widely-utilized method for growing a variety of plants including fruit, vegetable, nursery, and floriculture crops. Floriculture and nursery crops comprise almost 30% of the specialty crops grown in the U.S. with a total of $11.7 billion in sales in 2009 [5]. Container production in the U.S. currently accounts for approximately 90% of greenhouse, nursery, and floriculture crops [6].…”

Irrigating plants based on their water requirements enhances water use efficiency and conservation; however, current irrigation practices for container-grown greenhouse plants largely relies on growers’ experiences, resulting in leaching and/or runoff of a large amount of water. To address water requirements of greenhouse-grown plants, this study adapted a canopy closure model and investigated actual evapotranspiration (ETA) of Calathea G. Mey. ‘Silhouette’ and Stromanthe sanguinea Sond. from transplanting to marketable sizes in a shaded greenhouse. The daily ETA per Calathea plant ranged from 3.55 mL to 59.39 mL with a mean cumulative ETA of 4.84 L during a 224 day growth period. The daily ETA of S. sanguinea varied from 7.87 mL to 97.27 mL per plant with a mean cumulative ETA of 6.81 L over a 231 day production period. The best fit models for predicting daily ETA of Calathea and Stromanthe were developed, which had correlation coefficients (r2) of 0.82 and 0.73, respectively. The success in modelling ETA of the two species suggested that the canopy closure model was suitable for quantifying water use of container-grown greenhouse plants. Applying the research-based ETA information in production could reduce water use and improve irrigation efficiency during Calathea and Stromanthe production.

Nonnative invasive plants (weeds) negatively impact native biodiversity, ecosystem services, agriculture, and the economic interests and health of humans. Since 1902, biological weed control has been employed as a cost-effective and sustainable management option for weeds in the USA. However, biological control is not appropriate for all weeds, nor is sufficient funding available to develop biological control for all weed species. Researchers in South Africa recently developed a Biological Control Target Selection (BCTS) system as an objective, transparent, and simple approach to prioritizing weeds as targets for biological control. The system includes multiple attributes pertaining to the: (1) impact and importance of the target weed, (2) likelihood of achieving success, and (3) investment required to develop and implement biological control. Attributes are scored based on available literature, and the overall score for each weed is used to rank species according to their potential to result in successful biological control programs. This paper describes the adaptation of the BCTS for application to weeds in the western USA not already targeted for biological control.
