From the nursery

Leaf miner: Flies of different species can attack a wide range of ornamentals including Aquilegia, Betula, Buddleja, Chrysanthemum, Dianthus, Delphinium, Geum, Ilex, Iris, Laburnum, Lathyrus, Lonicera, Nasturtium, Potentilla, Symphoricarpus and others.

Control with Calypso, Decis (SOLAs required), Dynamec, Gazelle, Hallmark WZT (SOLA 2008-2944) or Toppel 100EC if seen.

Metal detecting: Make sure that you have a proper agreement with those searching your land or you may not gain from the finds. The Treasure Act Code of Practice and National Council for Metal Detecting Code of Conduct are useful documents and can be found online.

Revocations: Selected products containing chlorpropham (including Jupiter 40 EC), Gyro and UPL Bifenthrin have a final storage and use-up date of 31 July.

Rust: Keep a watchful eye and check the underside of the older foliage of Hypericum, Mahonia, hollyhock, Vinca, Salvia, Salix and roses for rust. Spray with Amistar (SOLA 2009-0443), Bumper 250EC (SOLA 2009-0707), Nimrod or Systhane 20EW when seen.

Quad bikes: With quads increasingly popular on nurseries for towing, spraying and transport, it is important to make sure that any going on the road are fully compliant with highway laws as well as health and safety standards. Look through the HSE AIS 33 leaflet Safe Use of All Terrain Vehicles in Agriculture and Forestry. A checklist (AFAG 701) on safe working practices is also available from the HSE website. Visit the European ATV Safety Institute website at www.quadsafety.org.

PGRs: Now is the time to apply Cycocel to Camellias for sale next spring. The rate is 3,000ppm. Continue with liquid feeding for this month only.

Privet: Leaf rolling caused by the privet aphid is now showing up. Control pests on outdoor crops with Aphox, Decis, Gazelle or Talstar 80 Flo.

Shot-hole: In wet weather, or with overhead irrigation, apply a tank mix of copper plus Serenade ASO (SOLA 2009-0246) to control the spread of bacterial infections on ornamental Prunus and Magnolias.

Heaters: Use the summer time to have your heaters serviced and made ready for use in the late autumn. Get the job out of the way so that you do not have a panic when the frosts start.

Fremontedendron: Apply Aliette 80WG to plants to control the aerial dieback caused by Phytophthora that often occurs on the stems.
