Postharvest Storage, Packaging, and Handling of Specialty Crops: A Guide for Florida Small Farm Producers

Jonathan A. Watson, Danielle Treadwell, Steven Sargent, Jeffrey K. Brecht, yWilliam Pelletier

Every year farmers must harvest their crops. This process marks the end of the growing season and carries social significance in communities, but it also creates challenges for producers trying to deliver fresh, high-quality produce to market. Good postharvest practices establish appropriate cold chains that maintain the correct temperatures, humidity, and respiration rates while also ensuring the safety, sanitation, and quality of the fruits. These postharvest practices differ, depending on the size and economic situation of an operation. This fact sheet provides postharvest storage, packaging, and handling recommendations for small farm specialty crop producers.

Weeds as Reservoirs of Plant Pathogens Affecting Economically Important Crops

Morgan Byron, Danielle Treadwell, and Peter Dittmar

Weeds are a major contributor to yield loss and reduction in yield quality in an agricultural setting, competing with the crop for resources like light, water, and nutrients. This competition along with the cost of weed management strategies like tillage and herbicides, are responsible for the economic impact of weeds, which can reach into the billions. In addition to the damage caused by direct competition, weeds can also harm crop plants by acting as reservoirs for destructive plant pathogens, the insect vectors that move these pathogens from plant to plant, or both. The objective of this publication is to summarize previously published weed-pathogen associations to help growers scout and monitor pathogens in weeds near production areas.

Integrated management strategies are detailed, including cultural controls, certified seed selection, and specific fungicide programs tailored for both conventional and USDA-certified organic production systems. Emphasis is placed on proper disease diagnosis and fungicide resistance management to assist producers in making effective management decisions.

Seeding the Garden

Danielle Treadwell, David Outerbridge, Tabitha Petri, Tabitha A. Petri, James Stephens, yJames M. Stephens

For each vegetable you plan to grow in your garden, you will have to decide whether to start it from seed, from transplants, or from plant parts. The main advantage in starting directly from seeds is that you have a wider selection of varieties and sources to choose from compared to buying transplants at a garden center. Furthermore, not all vegetables do well when transplanted, and most vegetables can be grown from seed sown directly in a garden row. This publication provides considerations and best practices for selecting and planting seeds in home and community gardens
