The greenhouse-tomatoes list was created to provide a method for commercial greenhouse tomato growers to communicate with each other to learn from others' experiences. Its purpose is to connect growers with vendors of greenhouses, fertilizers, seeds, and other supplies, and to facilitate networking among growers, agents, specialists, and researchers. The goal of the greenhouse-tomatoes list is to develop high quality discussion that benefits commercial growers and the entire greenhouse tomato industry. This is accomplished by promoting the list to growers; keeping the list small so that the traffic is manageable; avoiding promotion to hobbyists so the list does not become cluttered; avoiding SPAM. Excellent majordomo software has been 100% effective in the latter. The list was first offered to growers at the 2004 Greenhouse Tomato Short Course (GHSC) in Jackson, Miss. Then, it was promoted through other e-lists for vegetable specialists, new crops, greenhouse growers, hydroponics, etc. The final phase was to promote it at various grower meetings around the U.S., through trade magazines, and at the 2005 GHSC. Currently, the list consists of 141 members. Subscribers are from the U.S., Argentina, Australia, Canada, England, Germany, Newfoundland, Pakistan, Romania, South Africa, Virgin Islands, and Thailand. Demographics are 31% university, 15% suppliers, 34% growers, 20% unknown. The greenhouse-tomatoes list is housed on a server at Mississippi State University with nearly all functions handled seamlessly by majordomo software. To subscribe: send e-mail to [email protected] with the following message: subscribe greenhouse-tomatoes. You will get a confirmation email telling you that you must reply. You must be subscribed to send anything to the list. Once subscribed, to communicate with the whole group, address an email message to [email protected] and everybody on the list will receive it. To make this easy, the user can save that address to a nickname, such as ght or greenhouselist. More information can be found at http://www.greenhousetomatosc.com.

The Mississippi (MS) Greenhouse Tomato Short Course has been held every March since 1989. The purpose of this 2-day, intensive training is to educate growers so they will be able to successfully grow greenhouse tomatoes as a viable horticultural business. With a mixture of experienced, novice, and prospective growers, it is just as important to provide current growers with research based, practical information, as to expose potential growers to the realities of the business, helping them make an informed decision before investing time and money. Beginning as a small program for a handful growers in the conference room at the Truck Crops Experiment Station, it has gradually grown in number and diversity of participants and invited speakers, depth of subject matter, and geographic origin of growers and speakers. The 2003 program had 142 participants from over 20 states and 4 countries, making it the largest such program in the United States. This is in keeping with the recent trend. The typical lineup of topics includes the basics of producing a commercial crop of hydroponic greenhouse tomatoes, the budget for establishing and operating a greenhouse business, marketing and promotion, pest and disease identification and management, and the grower's point of view. Other topics, varying year to year, include heating, cooling, and ventilation of greenhouses, record keeping, new technologies, biological control, diagnostics, and alternative crops. For 2004, the subject of organic production will be introduced. With targeted extension programming such as this Short Course, the greenhouse tomato industry in MS has grown from 15 growers in 1989 to 135 growers today, producing $6.5 million in annual gross sales.

Ciguatera poisoning (CP) poses a significant threat to ecosystem services and fishery resources in coastal communities. The CP-causative ciguatoxins (CTXs) are produced by benthic dinoflagellates including Gambierdiscus and Fukuyoa spp., and enter reef food webs via grazing on macroalgal substrates. In this study, we report on a 3-year monthly time series in St. Thomas, US Virgin Islands where Gambierdiscus spp. abundance and Caribbean-CTX toxicity in benthic samples were compared to key environmental factors, including temperature, salinity, nutrients, benthic cover, and physical data. We found that peak Gambierdiscus abundance occurred in summer while CTX-specific toxicity peaked in cooler months (Feb–May) when the mean water temperatures were approximately 26–28 °C. These trends were most evident at deeper offshore sites where macroalgal cover was highest year-round. Other environmental parameters were not correlated with the CTX variability observed over time. The asynchrony between Gambierdiscus spp. abundance and toxicity reflects potential differences in toxin cell quotas among Gambierdiscus species with concomitant variability in their abundances throughout the year. These results have significant implications for monitoring and management of benthic harmful algal blooms and highlights potential seasonal and highly-localized pulses in reef toxin loads that may be transferred to higher trophic levels.

AgriPhage applied as a preventative foliar spray significantly reduced severity of bacterial canker of greenhouse tomato in two of three years. Area under the disease progress curves (AUDPC) indicated that AgriPhage slowed the progression of bacterial canker symptom development by 50% and 59% in 2006 and 2007, respectively. Plant mortality was significantly reduced by 76% in 2006 as compared to the inoculated control. AgriPhage-treated plants produced significantly greater total yield in 2006 only. Copper and Kasumin sprays also significantly reduced severity (AUDPC) of bacterial canker in 2007 as compared to the inoculated control. However, none of these treatments reduced symptom development or increased yield in 2008. Accepted for publication 9 April 2009. Published 12 May 2009.
