Abstract: Abdelbaset I. Yagubi, Alan J. Castle, Andrew M. Kropinski, Travis W. Banks and Antonet M. Svircev. The complete genome of an Erwinia amylovora bacteriophage, vB_EamM_Ea35-70 (Ea35-70), is 271,084 bp, encodes 318 putative proteins, and contains one tRNA. Comparative analysis with other Myoviridae genomes suggests that Ea35-70 is related to the Phikzlikevirus genus within the family Myoviridae, since 26% of Ea35-70 proteins share homology to proteins in Pseudomonas phage φKZ.

Abstract: Alexandra Grygorczyk, Jessica Turecek and Isabelle Lesschaeve. The current study aimed to determine how the pest management practice applied during crop production may impact consumer purchase intentions of an edible (tomato) and a non-edible (chrysanthemum) greenhouse crop. The study examined five pest management practices and applied conjoint analysis to evaluate the relative importance of the pest management practice compared to several other product factors (price, benefit claims related to the pest management practice, tomato variety/flower colour, quality) in contributing to consumers’ purchase intentions. Out of the factors examined, price (26–29 % relative importance) and the pest management practice (22–25 % relative importance) were the most important to consumers. In both studies, there were segments of the sampled populations (13.5–24 %) for whom the pest management practice was the most important factor driving purchase decisions. These segments had significantly more consumers with low confidence in science and technology and preferred products grown using organic practices or pests’ natural predators. In the tomatoes study (crop intended for consumption), the proportion of pest management conscious consumers nearly doubled compared to the chrysanthemums study. Findings suggest that making consumers aware that a product has been produced using pests’ natural predators (i.e. using biocontrol strategies) for pest management could convince a significant segment of the population to purchase these products over other similar products. When the crop is edible, a higher proportion of consumers becomes concerned with the production practice.

Abstract: Bernard Goyette, Marlène Piché, Michael Brownbridge and Darby McGrath. There is a need to develop methods that would allow plant health and survival potential to be quantified in real time, particularly in the different phases of bare-root handling. Such methods would allow the impact of different stresses experienced throughout storage and transport on establishment success and growth of the bare-root plant to be quantitatively defined. This review concentrates on the impact of pre-lifting, pre-transplanting and post-transplanting considerations and identifies tools that can be applied for monitoring plant quality. Root and shoot culturing, lifting and transplanting timing, water stress and storage/transport handling are all significant factors in the post-transplant performance of bare-root material. Different postharvest tools and indicators are also examined for their efficacy and contribution to plant quality. Chlorophyll fluorescence and root respiration are useful as indicators of water stress and dormancy; however, more practical equipment should be developed in both instances for greater adoption of these practices. Hydrophilic gel slurries can be used either during storage and immediately prior to transplant as an additional prevention of desiccation but will not restore vigor to damaged plants. Cold storage at optimum temperature should be adapted to maintain the target relative humidity; otherwise the storage period should not exceed 4 weeks for unprotected bare-root plants. Many improvements have been made in the ability to predict the effects of stresses experienced by bare-root material. However, more equipment, metrics, species and site specific research would enhance monitoring of bare-root quality.
