Do you have a strategy to help mitigate pests coming into your facility, like dipping cuttings upon receipt?
The CFIA has recently released the Floriculture Sector Biosecurity Guide. Despite it’s imposing name, this is an excellent “road map” to help protect your facility from unwanted pests. The Guide offers biosecurity strategies from the time plants come in the front door ’till they’re out in the compost bin.
Don’t have a facility-wide Pest Management Program in place? This guide can provide the framework. (Why start from scratch?). Already have a strategy to mitigate risks from pests at your farm? Compare YOUR plan with the Floriculture Guide to see if you’ve overlooked anything.
