The role of crop production practices and weather conditions in microbiological safety of tomatoes and peppers

Figure 1. Tomato plants in the field at the UF/IFAS Research and Education Center in Citra, Florida, are subjected to different irrigation and fertilization regimens.Salmonella and other human pathogens can contaminate produce at any stage from “farm to fork.” If we can better understand how production practices may make crops more or less susceptible to human pathogens we may be able to significantly reduce the number and severity of the produce-associated outbreaks. This 3-page fact sheet provides up-to-date information about tomato production practices and their relationships with Salmonella.

Hand Pollination of Tomato for Breeding and Seed Production

Figure 2. Emasculation of the flower leaving the stigma exposed for pollination.Hand pollination is a technique that is used for breeding new tomato varieties with desirable characteristics such as plant vigor, disease resistance, and uniform fruit quality and plant growth; since tomatoes have complete flowers and are self-pollinated, it usually is unnecessary to hand pollinate the flowers for fruit production. This 4-page guide illustrates selection and emasculation of flowers from the plant receiving pollen, pollen collection and drying, and pollination of the stigma.

Blossom Drop, Reduced Fruit Set, and Post-Pollination Disorders in Tomato (HS1195)

Figure 1.  Reproductive features of tomato flower. Left: female pistil. Center: open tomato flower. Right: male stamens.Blossom drop and reduced fruit set in tomato can seriously impact yields. Growers in Florida routinely experience such problems and inquire about the cause and possible preventative measures to reduce flower loss and improve yields. The problem can be frustrating and difficult to manage in some situations.
