Pansies - After transplanting, ensure that plant-growth regulator and downy mildew controls are in place.
Powdery mildew - Include Corbel, Cyflamid (EAMU 2007-0512) or Folicur on outdoor ornamentals - not on warm days. Add in a wetting agent to fungicides (check labels and EAMUs) where infections persist.
Rust - Control using Amistar (EAMU 2009-0443), Bumper 250EC (EAMU 2014-1274), Difcor 250EC (EAMU 2014-1023), Folicur, Plover (EAMU 2005-0159), Signum (EAMU 2012-2141) or Systhane 20EW.
Scale insects - "Crawlers" may still be on acer, cornus, ilex, magnolia and other shrubs. Before egg-laying starts, control with Decis (non-IPM), Envidor (EAMU 2012-0254), Majestik, Pyrethrum 5EC, Savona, SB Plant Invigorator or Spruzit.
Despatching plants - Leftover plants can act as a "sink" for transfer of infection onto new crops. Make sure these are included in your pest and disease control programmes.
Needle cast - Take preventive action on conifers using Bravo 500 (EAMU 2011-1130) on outdoor crops, Octave, Serenade ASO (EAMUs required), Signum (EAMU 2012-2141) or Switch.
Bacteria - Keep infections and stem cankers at bay by using tank mixes of Cuprokylt (EAMU 2015-1176) and Serenade ASO (EAMUs required). It is important to clean up plants as much as possible before leaf-fall.
Glasshouse computers - Carry out routine checks on temperatures, humidity levels, vents and screens. Change settings in line with any variations in weather conditions.
Leaf hoppers - Check chrysanthemum, Lamium, Nepeta, lavender and salvia. IPM-compatible products include Chess WG (EAMU 2008-2834), Mainman (EAMU 2013-0045), Majestik and SB Plant Invigorator. Non-IPM products: Calypso (EAMUs required), Decis, Gazelle SG or Hallmark WZT (EAMU 2008-2944). Products with physical action (short-term effect on predators) that may provide control include Pyrethrum 5EC and Spruzit.
