practices. Biological weed control includes introduction of an organism to reduce the population

of undesirable pests.

 Chemical weed control includes use of herbicides and fumigants to control weeds. Non-

fumigant chemicals include: DCPA (Dacthal) which controls germinating annuals; Diquat which,

via contact, burs down vines after final harvest; MCDS (Enquik) which is a post-emergence

control of broadleaf weeds; Metribuzin (Sencor) which controls post-emergence of small weeds;

Napropamid (Devrinol) which is a preplant incorporated-control for germinating annuals (applied

before plastic application); Paraquat (Gramoxone) for post-emergence contact-control for all

emerged weeds (used in row middles between beds); Sethoxydim (Poast) for post-emergence

control of grass weeds; and Trifluralin (Treflan) applied preplant for control of germinating

annual weeds (for application rate and comments, refer to pp. 339-342 of the Florida Weed

Control Guide, 1993). Fumigant chemicals used to control weeds include methyl bromide and

Vapam.


Insects

 Insects, such as wireworm, may increase in population with removal of methyl bromide

in tomato production. Methods of control for wireworm include Diazinon, a non-fumigant

chemical, and Telone and methyl bromide which are fumigants (for application rates and

comments refer to the Florida Insect Control Guide, 1993, p. 542).


Strawberries

 Approximately 3,000 to 5,500 acres of strawberries are planted annually in Florida. For

the 1991-92 season, 4,700 acres of strawberries were harvested in Florida. Hillsborough and
