(Poast) is a post-emergence spray for control of grass weeds (for application rate and comments concerning these chemicals, refer to p. 317 of the Florida Weed Control Guide, 1993). Fumigant type chemicals such as methyl bromide mixed with varying concentrations of chloropicrin can be used for control of weeds prior to planting a crop. Vapam can also be used to treat soil prior to planting a crop. Insects Insects such as wireworm may increase in population with the removal of methyl bromide in eggplant production. Methods of control for wireworm include Telone and methyl bromide (for application rates and comments regarding Telone, refer to pp. 111-112 of the Florida Insect Control Guide). Methyl bromide is also used as a pre-plant fumigant for control of soilborne insects. Cucumbers Approximately 16,000 to 23,000 acres of cucumbers are planted annually in Florida. For the 1991-92 season 16,500 acres of fresh market cucumbers and 2,500 acres of processed cucumbers were harvested in Florida, primarily in Collier, Manatee, Hardee, Palm Beach (East), Hendry and Lee counties. In Florida, 2,500 acres of pickling cucumbers were harvested in the 1991-92 season (FASS, 1993). There are numerous varieties of (slicing) cucumbers such as Dasher II, Floracuke, Early Triumph, Poinsett 76-S, Sprinter 440, and Raider. Pickling varieties can include Addis, Calypso, or Carolina (Hochmuth, 1988d).
