Abstract
Cowpea mild mottle virus (CPMMV) was reported causing systemic mottling, chlorotic blotch, and leaf malformation on cowpea from several tropical regions of Africa, Asia, and South America. Recently, CPMMV infection was reported from several soybean growing areas in Indonesia with high incidence. The disease tends to spread and develop very rapidly. A field experiment at Bogor was conducted to study disease development caused by CPMMV and its impact on soybean cv yield. Wilis. Soybean field was infested by CPMVV at different infection levels, i.e., 0%, 10%, 30%, and 50%. Virus indexing was done at two weeks interval by symptom observation and leaves collection for virus detection using dot immunobinding assay. Mild mottle symptoms were first shown 14 days after planting. The infection rate decreased with the increasing number of initial inoculums, whereas disease incidence increased with the growing number of initial inoculums. The infection of CPMMV caused a reduction of pods number and seed number, i.e., up to 18.81% and 30%, respectively.
