Check pesticide labels and off-label approval information before tank mixing. Addit, Codacide Oil or Logic can improve rainfastness.
Add in a wetting agent to fungicides (check labels and EAMUs) to help further control persistent infections. Include Corbel, Cyflamid (EAMU 2007-0512) or Folicur in outdoor crop spray programmes, but not on warm days.
Fremontodendron & Ilex Apply Fenomenal to control aerial Phytophthora spp. that cause dieback.
Algae in reservoirs
Use barley straw, products containing harmless blue dyes such as Dyofix Pond Liquid or ultrasonic waves for good effect.
Bed watering Automatic irrigation systems can produce an uneven output — check crops along bed edges and pathways for drought. Keep different compost types and pot sizes separate where possible.
"Crawlers" may still be present on acer, Cornus, ilex, magnolia and other shrubs. Control these soft stages now before egg-laying. Products include Decis (non-IPM), Envidor (EAMU 2012-0254), Majestik, Pyrethrum 5EC, Savona, SB Plant Invigorator or Spruzit.
Maintain preventive sprays using Bravo 500 (EAMU 2011-1130), Dithane 945 (EAMUs required) Karamate Dry Flo Neotec or Proplant (EAMU 2012-3100). Control infections with Amistar (EAMU 2009-0443), Bumper 250EC (EAMU 2014-1274), Fenomenal (EAMU 2013-1990), Fubol Gold WG (EAMU 2013-2288), Invader (EAMU 2012-0109), Paraat (EAMU 2011-2585), Percos (EAMU 2013-0819), Pergado Uni (EAMU 2012-1605), Revus (EAMUs required), Signum (EAMU 2012-2141), Stroby WG, Subdue or Valbon (EAMU 2010-1513).
Basamid can still be used while soil temperatures are warm and soils are moist. Cover treated soil with polythene for better control and to help keep areas weed-free until planting preparations.
Ensure that crops have produced enough roots to get through the winter months. Damage from sudden sharp drops in temperature will not show through until the following spring. Small root systems will be prone to root rot pathogens. Stimulate root growth using high-phosphate products including Hortifeeds 1:4:1, Hortiphyte, Peters Plant Starter, Solufeed 1:5:1 or Universol Yellow.
