RESEARCH
The discovery of CsMIKC1 as a target for genetic
engineering could transform cannabis cultivation in
greenhouses, enabling the development of novel cultivars
with improved yields, according to the study's authors. By
leveraging this genetic insight, the industry may improve
efficiency and scalability to meet the rising global demand
for both medicinal and industrial products.
PEST MANAGEMENT
Root and soil treatments should be part of a broader IPM
strategy that includes biological controls, environmental
management and selection of cultivars more unfavorable
to pest levels. The holistic approach can help manage pest
populations more effectively and sustainably.
Recent research at Niagara College's Horticultural &
Environmental Sciences Innovation Centre (HESIC),
led by Scott Golem and faculty research lead Sebastian
Jacob, focuses on the challenges posed by cannabis aphids
(Phorodon cannabis) and rice root aphids to cannabis
crops. These pests significantly affect plant health and,
consequently, the profitability of cannabis growers.
Cannabis aphids and rice root aphids compromise key
growth parameters such as plant vigor, photosynthetic rates
and overall height. Notably, winged aphids create quality
concerns when they contaminate the final product. While one
study indicated that cannabis aphids have minimal impact
on THC concentration in certain cultivars, other research
highlights their damaging effects on dry mass and cannabinoid
profiles suggesting that the consequences of infestations can
vary across cannabis strains and environments.
Since legalization, the industry has adopted advanced
management strategies. These include starting with pest-free
plants, quarantining new stock and using cultural practices
such as heat treatment during sanitation. Additionally,
biopesticides have emerged as vital tools, complemented by
the introduction of Hop-Latent Viroid (HLVd) free tissue
culture materials, significantly improving pest control.
Efforts to tackle rice root aphids have progressed through
preventive measures and the use of biopesticide drenches.
Beneficial fungi are becoming integral to managing these
pests, as their presence in root zones helps reduce aphid
populations. Despite these advances, challenges remain,
particularly as infestations spread in both cannabis and
hemp production across Canada and the U.S.
The research team is focusing on innovative pest
management practices, especially given the limited options
for controlling these pests. They emphasize evaluating
the phytotoxicity of various management products while
striving for high efficacy with fewer applications. Recent
findings show some new biopesticides achieving over 90%
