Tomato – Heliothis/Tomato Budworm (Helicoverpa spp.)

Crop:         Tomato
Insect(s): Heliothis/Tomato Budworm (Helicoverpa spp.)


  1. Monitor pest levels and do not spray unless pest thresholds are reached.
  2. DO NOT apply products outside their window of application for that chemical group.
  3. Use an integrated pest control approach where both chemical and nonchemical measures are adopted as part of the overall strategy. Examples are the use of predators/parasites and relevant cultural practices (crop hygiene, rotation of planted areas, and strategic time of planting.
  4. Seek local advice on pest incidence and the risk of resistance development from insecticide programs used to control heliothis in other crops or to control other pests
  5. When using insecticides/miticides to control other pests on tomato, consider the chemical group in relation to contributing to resistance development of heliothis.
  6. Avoid using insecticides from the same chemical group against Helicoverpa spp. or other pests, as this will increase the selection pressure.
  7. Do not re-spray a crop in the same season where a failure (which is known or unknown) has occurred using the same insecticide or other active ingredient from the same chemical group.

Notes regarding the application of insecticides:

  1. To ensure the most effective control of the pest:

a) Product labels should at all times be carefully read and adhered to;

b) Full recommended rates of registered insecticides should always be used; and

c) Ensure good coverage of the target area to maximise contact.

CropLife Australia’s Resistance Management Strategies provide a guide for crop protection product rotation through product groups. The strategies are a useful tool that supports farmers’ adoption of resistance management. All crop protection products must be handled and applied strictly as specified on the product label or APVMA permits.

These Resistance Management Strategies do not replace product labels. They are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. It is important to check with the Australian regulator’s (APVMA) product database for contemporary information on products and active constituents. The database can be sourced through
