JB in BC: The nursery & landscape sector perspective

JB in BC: Nursery sector perspective The nursery sector and invasive pests: Invasive plant pests = regulated and/or quarantine pests Regulated pests = movement restrictions on nursery stock Movement restrictions = loss of business and increased costs for the nursery sector

Nursery sector and invasive pests: Plum Pox Virus (PPV) in Ontario PPV is a pest of concern to stone fruit industry, mostly peaches Does not cause tree mortality, affects fruit yield and quality Can infest ornamental varieties, purple leaf sand cherry, but very rare CFIA established quarantine zones in Niagara area, undertook an eradication program Nursery growers not able to ship P. cistena outside of quarantine area, market inside quarantine area is very limited; significant loss of business for many growers Non-propagation rules, required relocation of business facilities to areas outside of quarantine zone, significant expense to growers Fruit growers (orchardists) compensated for tree removal and replant, no compensation to nursery growers for lost business or added expenses

Nursery sector and invasive pests: Emerald ash borer in ON and QC EAB is a hugely destructive pest which has resulted in the mortality and removal of ash trees throughout ON and QC municipalities Demand for a tree that was once considered the go-to selection for all urban foresters died almost overnight; growers across ON and QC have burned millions of dollars of inventory even before EAB was present in growing regions

Nursery sector and invasive pests P. ramorum (Sudden Oak Death) in BC P ramorum classified by CFIA as a quarantine but nonregulated pest Host plants found by CFIA ordered for destruction CNLA was instrumental in helping sector to realize compensation for destroyed plants Loss of sales to out-of-province markets, primarily ON and QC, not eligible for compensation Cost of compliance to industry-developed certification programs is significant

Other regulated pests resulting in movement restrictions: Asian longhorn beetle Almost eradicated? Gypsy moth Pine shoot beetle

Japanese beetle in BC Japanese beetle is regulated on a category basis Category 1: Pest-free (BC) Category 2: Low pest prevalence (NL) Category 3: Infested (ON, QC, NB, NS, PEI) Category 4, Not known to be infested (climate) MB, SK, AB Movement restrictions from infested to non-infested areas are very severe and will result in increased production costs and loss of access to domestic and export markets

BC as a Category 1 province Climate No natural control by weather as seen in Ontario and Quebec (partial control of JB populations) Movement restrictions CFIA s movement regulations from an infested area to Category 1 (domestic and export) are particularly onerous Requires chemical treatment, larger items can t be moved into Category 1 areas Large number of infested areas in eastern provinces makes JB almost a non-regulated pest
