Abstract
The present study aimed to evaluate some plant extracts from Plectranthus tenuiflorus, Azadirachta indica, Clerodendrum inerme, Schinus terebinthifolius and Mirabilis jalapa as antiviral materials against Bean common mosaic virus (BCMV) in bean plants. The results showed that all the tested plant extracts were effective in reducing the number of local lesions formed by BCMV. The mixing of P. tenuiflorus extracts with BCMV inoculum achieved the highest reduction in BCMV infection (92%), while the mixing of S. terebinthifolius extracts with BCMV inoculum recorded the lowest reduction in BCMV infection (68%). Seed treatment with 1% (w/v) of P. tenuiflorus showed the highest reduction in disease incidence (93% and 85%) under greenhouse and field conditions, respectively. Spray treatments of P. tenuiflorus and M. jalapa reduced disease incidence to 12% and 17% under greenhouse conditions, whereas under field conditions they reduced disease incidence to 17% and 23%, respectively. Protein analysis revealed different effects of the tested treatments on bean plants indicating different gene(s) expression. This study suggests the possibility of using plant extracts for controlling BCMV infection.
