摘要

A written survey administered to 3,500 Florida cattle producers in 2006 documented tropical soda apple as the most common pasture weed across the state of Florida. Over 80 of the survey respondents reported tropical soda apple on their ranches, andover 65 declared the plant to be a major problem for their cattle operation. On ranches that reported tropical soda apple infestations, the level of pastures infested with this weed ranged from a low of 4 in north Florida to a high of 12 in centralFlorida. The cattle producers' most common strategies to tropical soda apple were herbicide application and mowing. These strategies were used by 32 of respondents in north Florida, 75 in central Florida, and 76 in south Florida. On a statewide basis, 20 of catde producers used herbicides alone, 7 used mowing alone, and 20 used both methods. Some catde producers reduced the cattle stocking rate as a consequence of tropical soda apple infestations. This negative impact was reported by only 2 of catde producers in north Florida, 6 in central Florida, and 7 in south Florida. With the use of the economic input/output model IMPLAN, tropical soda apple control costs resulted in economic losses throughout Florida of $15 million annually in 2006 to cattle producers and their supporting business sectors.
