Why use Calypso

Orchards are under continual threat of pest attack during the season and tackling them, with minimal impact on natural predators and beneficials, is vital to successful integrated pest management. Calypso has been the cornerstone of pest control in apples for a number of seasons as it is robust and rapid with a good IPM fit including safety to bees. It can even be applied during flowering.

Main advantages

  • Fast-acting and long-lasting
  • Good IPM fit
  • Wide pest spectrum
  • Flexible application timing according to pest
  • Bee safe can be applied during flowering
  • Effective even at lower temperatures
  • EAMUs on soft, cane and stone fruit

Getting the best from Calypso

To get the best from Calypso against rosy apple aphid, a pre-blossom spray should be applied at the first sign of the pest, usually flower buds visible (GS 55), and not later than pink bud (GS 57). A follow-up post blossom spray of Calypso may be required; apply from the end of flowering (GS 69) to fruit half final size (GS 75). When spraying post-blossom it is particularly important to achieve full penetration of the leaf canopy and uniform coverage of the foliage and blossoms/fruitlets with the aid of a higher water volume.

Important things to remember

Under certain circumstances the cider apple variety Michelin may exhibit symptoms of leaf scorch following application of Calypso, particularly when treated around petal-fall. If treating this variety, ensure in particular that trees are not under stress such as nutrient deficiency and avoid using the product in tank-mixtures.

Using Calypso as part of a programme

With up to two applications in a season and its wide pest spectrum, Calypso is ideal for Integrated Pest Management as part of orchard control programmes.
