From: Virucidal activity of silver nanoparticles against Banana bunchy top virus (BBTV) in banana plants
Effect of treatment with AgNPs on BBTV infected banana plants, compared with healthy, nano- and viral controls. (1) Healthy control. (2) Banana plants treated only with 50 ppm AgNPs (nano-control). (3) Banana plants infected with BBTV (viral control), photoplate showing symptoms of dark green colored and form a “hook” shape on the midrib, reduced size, brittle of the leaves and gather at the top of the plant making a resetting shape. (4) Banana plant treated with 40 ppm AgNPs post-BBTV inoculation showing light green blade and light green streak on the midrib. (5) Banana plant treated with 50 ppm AgNPs post-BBTV inoculation showing no symptoms. (6) Banana plant treated with 60 ppm AgNPs post-BBTV inoculation showing phytotoxicity on the plant
