Insect(s): Heliothis/Tomato Budworm (Helicoverpa spp.)
- Monitor pest levels and do not spray unless pest thresholds are reached.
- DO NOT apply products outside their window of application for that chemical group.
- 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.
- 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
- When using insecticides/miticides to control other pests on tomato, consider the chemical group in relation to contributing to resistance development of heliothis.
- Avoid using insecticides from the same chemical group against Helicoverpa spp. or other pests, as this will increase the selection pressure.
- 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:
- 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.
