Centre de recherche et de développement de Summerland
Le Centre de recherche et de développement de Summerland (CRD de Summerland), qui est situé au cœur de la vallée de l’Okanagan en Colombie-Britannique, a été créé en 1914. Il fait partie du réseau de 20 centres de recherche et de développement d’Agriculture et Agroalimentaire Canada (AAC).
Activités scientifiques
Les activités du CRD de Summerland portent sur l’atténuation des pressions environnementales, la lutte contre les menaces biologiques et l’intégration des systèmes de production et de transformation durables pour assurer un approvisionnement en produits horticoles et agroalimentaires de haute qualité et à valeur ajoutée. Les activités de recherche portent sur les cultures horticoles de grande valeur, notamment les raisins de cuve et les fruits de verger, et sur l’élaboration de méthodes et de stratégies économiquement viables pour assurer la prospérité de nos industries agricoles à l’échelle locale, nationale et internationale.
Le CRD de Summerland est l’un des sept sites où des essais au champ sur les outils et les technologies de lutte antiparasitaire sont effectués pour le Programme des pesticides à usage limité d’AAC. Le Centre héberge également la Collection canadienne de phytovirus.

Apple clearwing moth, Synanthedon myopaeformis (Lepidoptera: Sesiidae) is an invasive pest of apple trees of European origin, first detected in 2005 in British Columbia. Infestations have increased and become more severe since its initial detection; there has been an increased interest in ACM due to its potential link to Sudden Apple Decline in the region. ACM pupae have been observed primarily – although not always – infesting

apple tree graft unions, often opportunistically infesting burr knots, canker, or otherwise damaged or vulnerable tissue. Larvae infest the cambium layer for 1-2 years before emerging. During the 2020 and 2021 growing seasons, we evaluated insect netting (1/6″ square mesh polypropylene) applied over entire apple trees for management of ACM by assessing pupal casing counts near the graft union.. No effect was detected after one
season; however, this is likely due to ACM lifecycle and infestation from the year prior, when there was no netting applied. A reduction to 0% infestation with netting application was observed in a second season of use, while infestation increased in the un-netted treatments. Woolly aphid infestations were observed to be more severe in tree canopies under netting than in non-netted trees. It should be noted that this appeared to bean abnormal year for woolly aphid. Field evaluations will continue for at least one more season (2022); apple quality under netting vs under nonnetted, and spray pattern when applied through netting vs non-netted will be assessed in the final season.

Increased frequency and severity of heat waves and drought are becoming a major challenge for Okanagan fruit growers. These events can reduce fruit quality and compromise tree health, and may be an important trigger for sudden apple decline. A toolbox to help fruit growers mitigate the impacts of heat- and drought-related stress on fruit quality and tree health is urgently needed. Sprayable nanoparticle calcium carbonate is a potential tool for protecting fruit from sunburn and mitigating water stress, and is less expensive than shade cloth and/or evaporative cooling. This tool was tested on an experimental apple block at the Summerland Research and Development Centre over the summer of 2021. An initial spray was applied to test trees in early June, with a second spray applied immediately prior to the ‘heat dome’ event in late June, and a third spray in late July. Throughout the growing season, stem water potential, leaf transpiration and photosynthesis rates were monitored. At harvest, yield and fruit quality were assessed (e.g., sun burn [Schrader-McPherson scale], fruit size and weight, titratable acidity, and Brix. The calcium carbonate spray reduced the incidence of severe sun burn, but caused no other significant differences in fruit quality. When drought stress was applied, by temporarily cutting off the irrigation supply to both treatments, sprayed trees showed lower water stress than un-sprayed trees. Although just a preliminary study, this work suggests that sprayable protectants, such as nanoparticle calcium carbonate sprays, have potential for protecting fruit quality and mitigating drought stress during extreme heat or drought and may be an important, low-cost tool to include in Okanagan fruit growers’ climate change toolbox.
