for those cropping systems affected by the loss of methyl bromide. The numbers in parentheses

are the percentage adjustments to per acre yields resulting from the loss of methyl bromide.

These yield adjustments are at the low end of the range of yield adjustments provided by the

extension specialists and horticultural scientists.

 Another important point regarding the values in Table E. 15 is the impact of the loss of

methyl bromide on double crop systems. In those systems, the yield adjustment imposed on the

first crop ranges from 15 to 40 percent depending upon location. The yield penalties imposed

on the second crop were higher, ranging from 20 to 50 percent with the exception of

watermelons. The rationale for the larger yield losses on the second crop is that reduced weed

control would adversely affect the integrity of the plastic mulch and hence lower second crop

yields.

 Yield losses in both Palm Beach and Dade county resulting from methyl bromide ban are

projected to be larger than in southwest or west central Florida because of the lack of land in

the east coast production areas. Producers located in southwest and west central Florida have

access to a larger land area and would be able to move production to mitigate "old land disease".


Model Solution Under a Methyl Bromide Ban

 The acreage planted by cropping system and production area under a methyl bromide ban

 are shown in Table E.16. The results suggest that a ban on methyl bromide would have a

 devastating impact on the Florida fresh vegetable industry. Production of tomatoes, peppers,

 eggplant, and cucumbers would cease in Palm Beach county. Tomato production in Dade county

 would also be eliminated. Fresh vegetable production in both southwest and west central Florida
