Situation of tomato spotted wilt tospovirus in the northeast of Spain
The incidence and distribution of tomato spotted wilt tospovirus has been studied in the northeast of Spain. Samples have been collected at random from tomato crops grown in the field and from weeds, at the beginning of summer and at the beginning of autumn (1992 and 1993). The virus was detected by using DAS-ELISA. A total of 4057 samples has been analyzed. The authors found that the most affected areas were those near the Mediterranean Sea. In the continental regions with a less intensive cultivation, TSWV was not considered important. In addition, TSWV has only a low incidence on spontaneous weeds.
