Do you grow Boxwood? Listen up!

Nurseries who grow and ship Boxwood, please read. This post provides important information on new proposed requirements and an opportunity to provide feedback to CFIA.

In November of 2022, the Canadian Food Inspection Agency (CFIA) added Box Tree Moth to their list of regulated pests and have established a regulated area of the entire province Ontario. You can find the details of the pest risk management decision at this link here (RMD-22-02).

Presentation Description:

Peter Kamp will present a new steering principle to achieve crop goals based on the overall water balance of the plant. The unique starting point of this steering principle is a feed-forward control for the greenhouse climate and water-supply, based on water uptake, fixation of water and transpiration of the crop. The control follows the plant’s circadian rhythm in terms of growth and crop development and can be specifically tuned to the crop goals of the grower.

What do consumers value most when purchasing nursery plants?

Vineland Research and Innovation Centre and the Marketing& Consumer Studies department at the University of Guelph have partnered to better understand the factors consumers consider and value when purchasing nursery plants. Results from consumer interviews completed through in-store intercept interviews and an online survey of North American consumers in 2020 and 2021 will be highlighted. Since nursery centres have increased their online presence due to pandemic restrictions, we will provide recommendations on how best to position products for both in-store and online success.

Get Ready for Fall Dormant Horticultural Oil

In mid-late autumn, we have an opportunity to manage some of our plant pests, such as mite eggs and scale insect nymphs, before they go completely dormant.  Now that trees are starting to drop their leaves and the weather has turned mild for a bit, horticultural professionals have a great window for managing some overwintering plant pests! The full, dormant rate of horticultural oil is excellent for smothering juvenile stages of insects this time of year as long as the application isn’t followed too closely by a significant freeze event.  Magnolia scale (photo above: overwintering nymphs in autumn J. Llewellyn) populations were… Continue reading

Monitor Beech Trees For Introduced Beech Scale Nymphs in the Coming Weeks

White waxy filaments produced by beech scale mothers protect eggs and hatching nymphs on the trunk of this American beech (J. Llewellyn)

Introduced Beech scale (Cryptococcus fagisugae) goes hand in hand with beech bark disease (Neonectria faginata and N. ditissima).  It is believed that the wounds made by the tiny scale nymphs create entry points for the lethal fungal disease.   Beech scale is easier to see this time of year on our native American beech (Fagus grandifolia).  That’s because of the white waxy coverings the females produced to protect their eggs in late summer.
