Tomato – Heliothis/Tomato budworm (𝘏𝘦𝘭𝘪𝘤𝘰𝘷𝘦𝘳𝘱𝘢 spp.)

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

Guidelines:

1. Monitor pest levels and do not spray unless pest thresholds are reached.
2. Use an integrated pest control approach where both chemical and non-chemical 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).
3. 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.
4. When using insecticides/miticides to control other pests on tomato, consider the chemical group in relation to contributing to resistance development of
5. Avoid using insecticides from the same chemical group against consecutive generations of Helicoverpa or other pests, as this will increase the selection pressure. This does not apply to Bacillus thuringiensis (Bt) or Nucleopolyhedroviruses (NPV) products, as they are considered to have a lower resistance risk. To encourage beneficial insects, use Bacillus thuringiensis (Bt) or Nucleopolyhedroviruses (NPV) sprays and avoid broad spectrum insecticides where possible, particularly early to mid-crop cycle.
6. 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:
2. Product labels should at all times be carefully read and adhered to;
3. Full recommended rates of registered insecticides should always be used; and

Ensure good coverage of the target area to maximise contact.
