Description
Pineapple is the major agricultural commodity in Hawaii, cultivated on nearly 10,000 ha. Currently, pineapple production relies upon organophosphate and carbamate insecticides and nematicides for control of mealybug wilt and postplant nematode control. These insecticides and nematicides face registration challenges and could soon be unavailable to the industry. Consequently, the pineapple industry has the opportunity to adopt and incorporate practices that reduce or even eliminate organophosphate and carbamate pesticides from pineapple production. The pineapple industry, represented by the Pineapple Growers Association of Hawaii, is an EPA PESP member.

This project has two performance targets: to increase the utilization of an ant monitoring and control system to 40 percent of commercial fields in two years, and to eliminate the postplant application of organophosphate nematicides on 30 percent of the pineapple treated each year in two years. The project will accomplish the first target by documenting efficacy and economics of the system in demonstration fields and conducting training sessions. The project will take advantage of the deregistration of fenamiphos to assist the industry in identifying and addressing factors limiting the adoption of environmentally preferred postplant nematode control tactics. These activities will meet the second performance target.

Project goals and objectives
1. To increase the utilization of an ant monitoring and control system utilizing Amdro bait stations from one plantation to two, achieving implementation of the monitoring and bait stations on 40 percent of commercial fields in two years;
2. To eliminate the postplant application of organophosphate nematicides on 30 percent of the 3,000 ha of pineapple treated each year in two years.

Outcomes
Soon after the project was initiated, the management team from the most innovative pineapple plantation was replaced by a more conservative management team that opted out of cooperating with the project. However, the demonstration trials generated a lot of interest in nontarget clientele groups. Both coffee and banana producers became interested in monitoring and bait programs for controlling ants and secured funding for research and demonstrations for their own commodities.

Telone EC appeared to be a successful alternative for Nemacur for postplant control of nematodes but is phytotoxic and a balance must be struck between maximizing nematode control and minimizing damage to the plant. The LCF and MeloCon demonstration on the Dole Plantation will continue to Fall of 2006. These low impact pesticides have yet to produce great visual differences but it may be too early to tell.

The project cooperators felt they had succeeded by stimulating a) continued interest in ant monitoring and bait stations; b) attendance at pest identification seminars and training sessions; c) continued interest in alternative nematicides; and d) registration of 1,3-D EC for postplant uses.
