SUMMER Insecticidal Spray Oil

SUMMER Insecticidal Spray Oil  SUMMER Label

Product Overview

SACOA SUMMER Insecticidal Spray Oil (SUMMER) is classified as a horticultural mineral oil (HMO). HMO’s are an integral component of Integrated Pest Management (IPM)

HMO’s are considered ‘soft’ pesticides since they are generally specific to particular life stages of certain pests and also because they are not persistent in the environment.

With increasing pressure to reduce the use of chemicals in the environment, spray oils are expected to become a greater influence on the market.

The use of HMO’s as pesticides to control pests and diseases on many horticultural crops in IPM programs for sustainable long-term control is an area SACOA is committed to.

Product Advantages

  • Excellent emulsion stability under a range of water qualities and water rates.
  • Assists insecticide penetration, effectively modifying the epicuticular wax (lipid) surface of the pest to facilitate the passage of the pesticide more efficiently.
  • Reduces evaporation of spray solution before and after reaching the target surface.
  • Reduces the surface tension of the spray droplet, there by aiding coverage.
  • Produces a more uniform droplet reducing the very small and large droplets, alleviating the splash factor.
  • Extensive field experiments conducted in Australia indicate that SUMMER significantly improves the performance of foliar applied pesticides.
  • SUMMER may also be used to achieve similar benefits with certain other plant protection chemicals like miticides and fungicides.

Crop Safety

  • Do NOT apply pesticides, or other chemicals, incompatible with oil within 4 weeks before or after application of Benlate® as crop damage may occur.
  • Do NOT apply an oil if temperatures are expected to exceed 32°C within 24 hours of application.
  • Do NOT use on Glen Retreat variety of mandarins.
  • Do NOT apply an oil if trees are water stressed.
  • Do NOT apply Benlate® with SUMMER on Pome Fruit when temperatures exceed 28°C or after mid-November, or first cover spray.


There are certain conditions when the surface of recently emerged fruit is particularly prone to marking damage from spray applications of mancozeb.

In circumstances where application has been made to very rapidly growing fruit in hot conditions with strong direct sun light, it is recommended that all emerged bunches be bagged prior to spraying to minimise risk of fruit marking.

Sulphur-based Compounds

SUMMER is NOT compatible with wettable sulphur or compounds containing sulphur such as lime sulphur.

Spray Tank Cleanup

Always follow active label instructions for spray tank cleanup.
