Proven chewing pest control

Larvin® 375 Insecticide

Larvin controls heliothis and other chewing pests in a range of crops including cotton, pulses and tomatoes. As a larvicide, Larvin works primarily through ingestion targeting very small and newly hatched larvae. Provided good coverage is achieved, a lethal dose is ingested soon after larvae commence feeding. Residual activity is excellent and is also maximised by good coverage of the plant surface. Larvin also provides residual ovicidal action when applied to eggs.

FAQs

Question Answer
1 Will Larvin control larvae on new growth following application Larvin is a non-systemic insecticide, which means that new growth appearing after application will not be protected against insect attack.
2 How does Larvin work against pests? Larvin is a stomach poison larvicide and also an ovicide. It is most effective targeting eggs, however the larvicide activity will ensure that new hatchings are also controlled.
3 When using Larvin, does the higher recommended rate provide longer residual control? Yes, using a higher rate of Larvin will give slightly longer residual control but also should be used against heavier pest infestations. Larvin at the highest rate may provide up to 12 days residual control of target pests under ideal conditions.
4 Is Larvin a systemic insecticide? No, Larvin is not systemic. New growth that emerges following an application of Larvin will not be protected from insect attack. In cotton, to maximise residual protection, it is recommended to apply Larvin to "cut-out" crops.
5 Can eggs of H. armigera exhibit resistance to Larvin? The mode of action of Larvin makes it unlikely that resistance will develop in white and brown eggs.
6 What mechanism of tolerance does H. armigera exhibit? Thiodicarb resistance is primarily a "target-site" mechanism. This mechanism is unstable in the absence of selection, so that if carbamates are not used for a period, populations of H. armigera will revert back towards susceptibility.
