HPIRS

Growers wanting to know what pesticides they could use in bananas should try using the Hawai`i Pesticide Information Retrieval System (HPIRS). Access to the website can be located at the following URL: http://pesticide.hawaii.edu. The database is up-to-date, but does not include state, 24(c), Special Local Needs (SLN), registrations. Users still need to read all product labels (of the containers they intend to purchase) to determine if those pesticide products can be used for intended purposes. Pesticide products can be searched by site (e.g., banana), and the search can be narrowed by using other search options (e.g., pest to be controlled).

Pesticide Registration Projects Status

Spinosad. Success is now labeled for use in banana for thrips suppression. Supplemental labeling is available and users must have it in their possession.

Imidacloprid. Provado and Admire labels are pending. The Final Ruling for the tolerance in banana was published on 11 August 2006 in the Federal Register, so we are waiting for the EPA-approved labels to be sent to the Hawai`i Department of Agriculture for state approval.

Ethoprop. Mocap EC formulation will be cancelled in banana, but the 15% G formulation will remain registered in banana. A special adapter will be needed to accept the lock ‘n load container on to a backpack granular applicator. A prototype is being made by Bayer CropSciences; we will make it available for use when received (O`ahu only?).

Carbofuran. Furadan will be cancelled in bananas and some other sites, but no specific timeline has yet been published.

Coppers. Responded to EPA’s risk assessment and call for use information with regard to products used and use patterns in banana and other crops.

Metaldehyde. Responded to EPA’s risk assessment and call for use information. The use of metaldehyde in banana is not elgible for reregistration.

Efficacy Resarch

No efficacy research was conducted in 2006; however, we are interested in evaluating two new insecticides (dinotefuran and spirotetramat) for aphid control in banana. Conducting research in growers’ fields is difficult because of the uneven distribution of aphids, and their transitory nature which appears largely dependent on the environment. Also, resources (mainly personnel) are limited. We are considering initiating lab and greenhouse tests on tissue cultured banana.
