Tomatoes, peppers, eggplants and strawberries were grown in soils fumigated e (MBr) to determine the effect of MBr on the growth and yield, bromine (Br) content in the plants and the content of water soluble Br in the soils. The growth and yield of 4 tesded crops were not affected by MBr fumigation. Br content in the plant parts of 4 crops tended to increase with increasing amounts of MBr. On a dry matter basis Br content in the fruit of 3 crops at 0, 100, 200 and 400g/m3 MBr treatments was as follows: in tomatoes 99, 113, 129 and 186ppm; in peppers 77, 104, 181 and 282ppm; in eggplants 72, 124, 213 and 364 ppm, respectively. Br content in the fruit of strawberries at 0, 200, 400 and 800 g/m3 MBr treatments was 154, 179, 210 and 285ppm, respectively. Water soluble Br in soil just after fumigation was significantly increased with increasing amounts of MBr. It was markedly decreased one and a half months after MBr fumigation at 200, 400 and 800g/m3, and thereafter gradually decreased with time at 400 and 800g/m3.
