Form filling: For those of you that complete Integrated Administration and Control System forms, check your land areas and return forms before 17 May. If you complete Single Payment Scheme forms, you should have received them by now.
Leaf crinkle: Warm days and cool nights can result in the developing leaves of some crops becoming crinkled. This is not necessarily insect or herbicide damage but more likely the result of extremes between night and day temperatures.
Scab: As Malus, Pieris, Chaenomeles and Crataegus leaves develop they will become increasingly vulnerable to scab damage. Read the weather to control damage rather than spraying routinely. Scab can also be created by using sprinklers on protected crops. Amistar (SOLA 2009-0443), Bumper 250EC (SOLA 2009-0707) or Systhane 20EW can be effective on glasshouse and tunnel crops. Outdoors, eradicants include Radspor FL, which will control existing scab growth; Topas and Systhane 20EW have a 7-10 day protectant effect. If scab is present, the use of an eradicant followed by a protectant is important.
Woolly aphid: This pest can now be found on pines, Malus and beech. Control using Gazelle or Calypso (SOLA 2008-2831).
Thielaviopsis (black root rot): Hygiene is one of the most important control procedures as the disease is water-spread. Control with drenches of Cercobin WG (SOLA 2008-1384) and Scotts Octave. If the disease is under Mypex, consider drenching Revive or Serenade ASO (SOLA 2009-0246) in those hard-to-reach places.
Cherry aphid: Chess WG (SOLA 2008-2834) or Gazelle give excellent control over cherry black aphid on ornamental Prunus.
Whitefly: Combine Encarsia formosa and Eretmocerus eremicus for a more diverse approach to whitefly control.
Bed space: Use it wisely, choosing a strategic plan for what to place where, while you have the opportunity.
Willow anthracnose: This disease creates small purplish spots on leaves and shoots which enlarge causing leaf and twig death. Control with Amistar (SOLA 2009-0443), Cercobin WG (SOLA 2008-1384), Signum (SOLA 2009-1842) or Switch. Apply at bud break and through the summer when it is hot and dry. Salix matsudana 'Pendula' is reported to be resistant to this disease.
