Disease suppression of naturally occurring viruses by treatment with 2,3-butanediol (2,3-BDO). (A) Disease symptoms caused by naturally occurring viruses were evaluated at 90 days post-transplantation (dpt). (B) The induction of resistance against Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Tobacco mosaic virus (TMV), Tomato spotted wilt virus (TSWV), and Tomato yellow leaf curl virus (TYLCV) by application of 2,3-BDO was evaluated at 90 dpt in the field. Bars represent mean ± SEM (n = 100). The housekeeping gene CaUBQ was used as a reference in qPCR. (C) Fruit fresh weight per plant and the fruit yield of 20 plants treated with 2,3-BDO, benzothiadiazole (BTH), and water were assessed at 100 dpt. Different letters indicate statistically significant differences (P = 0.05). Error bars represent mean ± SEM.
