Dasheen (Taro) leaves (leaf production only) Growers, UH Agents, Retailers: Need your assistance soon as possible

Provado 1.6F 24C is set to expire September 11, 2012.  Bayer CropScience needs to receive grower or industry support letter/s to maintain the 24C with HDOA before the expiration date.  Support will allow the 24C conversion from the Provado 1.6 formulation to the Admire Pro formulation with the 5x treatments per year.  Provado 1.6 is no longer available.

Advantage with the 24C:

·         With an Admire Pro 24C:  Allows 5 application per crop vs 3 applications with the container label

o    Note:  Provado 1.6 inventories needs to be used under the existing Provado 24C.  After Sept 11, 2012, Provado1.6F on taro/leaf production will not be allowed.

What is needed if growers wish to maintain the 24C?: 

·         A brief support letter addressed and emailed to Danyel Ward – Registrations, Bayer CropScience, Danyel.Ward@bayer.com;  cc Ed.Ishida@bayer.com

o    Brief description on Dasheen (Taro) leaf production to control aphids requires the 5 treatments per crop season

The Admire Pro new label does have Dasheen (Taro) leaves with 3 applications per crop season.

LIFE was asked to check on the mite situation. LIFE consulted Dick Tsuda, CTAHR Entomologist who confirmed the presence of 4 Tetranychus mite species. Tetranychus mites may be found on taro. Tetranychus cinnabarinus (carmine spider mite), T. neocalidonicus (vegetable mite), T. tumidus (tumid spider mite), and T. urticae (two spotted spider mite) were detected. According to Tsuda, "these mites are considered very similar and difficult to separate because of overlapping coloration."
