Hortgro Launches Centre to Tackle Invasive Pests in Deciduous Fruit Industry

Hortgro Launches Centre to Tackle Invasive Pests

The South African deciduous fruit industry proudly announces the
launch of a Centre of Excellence dedicated to advancing pest monitoring and
safeguarding the future of the industry. This new initiative, spearheaded by industry
association Hortgro, addresses the increasing challenges posed by invasive pests and
diseases.

Hortgro Executive Director Anton Rabe emphasized the urgent need for comprehensive pest
surveillance as new pests increasingly threaten the industry’s sustainability and profitability,
from crop damage to quarantine risks. “We must understand where pests occur and where
they don’t, as this directly influences crop protection strategies and practices,” Rabe stated.

Catching an invasive pest as soon as it arrives in the county may allow us to eradicate it
before it has gained a foothold. In addition, advance warning on the arrival of a pest or
disease buys our industry critical time to develop management practices and manage
phytosanitary concerns.

To meet this goal, the Centre of Excellence will build upon the monitoring capacity of FruitFly
Africa (FFA), an operating company with industry-wide support, which has managed pest
monitoring services since 2001. The FFA has been instrumental in tracking and controlling
pests like the Mediterranean fruit fly across all major deciduous fruit production areas. Their
initiatives include monitoring more than 6,000 traps and producing and releasing millions of
sterile Mediterranean fruit flies annually to manage populations.

The Centre will enhance these efforts, expanding surveillance to other significant pests,
including the Polyphagous Shot Hole Borer (PSHB) and spotted wing Drosophila (SWD). This
strategic expansion positions the deciduous fruit industry as a proactive leader in pest and
disease surveillance. The capacity established at FFA can also be utilized by other industries,
such as berries, wine and table grapes.

The Centre of Excellence initiative will ensure that the deciduous fruit industry remains resilient
and internationally competitive despite the threat of invasive pests.
