If necessary, apply a broad- spectrum fungicide treatment in the field before taking cuttings. Avoid taking cuttings when wet and avoid or remove soil particles. Do not co- mingle cuttings from different stock in water. Soak cuttings in a disinfectant solution, when appropriate. *Note. This section addresses the risks associated with purchasing propagative stock plants. Although it may be preferable to use stock that is on hand, this is not practical and not a normal industry practice. The BMP's listed are referring ONLY to stock that is purchased. BMP's that addressed on site TC, unrooted cuttings or other stock processes were moved to PRODUCTION tab. Propagation and production of greenhouse plants from cuttings whether from domestic, on site or foreign sites should be produced using the same BMP's
