Acaricides / Miticides > Unclassified acaricides ActivityAcaricide/Miticide, insecticide.
Pyridaben is a contact acaricide. It is active against motile stages of mites and also controls whiteflies. It has a rapid knockdown effect. Residual activity lasts for 30-40 days after treatment. The product has no plant-systemic or translaminar activity. Pyridaben controls hexythiazox-resistant mites.
Nissan recommends only one application per season to fruit, to avoid the build up of resistance. Field trials suggest that pyridaben has a moderate but transient effect on predatory mites, although this is not as marked as with pyrethroids and organophosphates. Nissan believes that the product is compatible with IPM programmes. Late spring to early summer applications are recommended for the control of mites. In field trials, pyridaben has shown no phytotoxicity at recommended rates. In particular, no russeting of apples has been observed. CropUseCrop uses:
