Tomato severe rugose virus (ToSRV) is a serious and prevalent begomovirus that causes severe mosaic and yield loss of tomato plants in Brazil. The virus is transmitted by Bemisia tabaci bitotype B (MEAM1) in a persistent circulative manner. This study evaluated the efficacy of cyantraniliprole foliar spray, cyantraniliprole root drenching, spiromesifen, thiamethoxam, and cartap on the mortality of Bemisia tabaci byotipe B and simulated primary and secondary transmission of ToSRV. None of the insecticides were effective in controlling primary transmission of ToSRV by B. tabaci. Cyantraniliprole root drenching, cartap, and cyantraniliprole foliar spray were effective in controlling secondary transmission of the virus, and infections were reduced by 94.5, 89.6, and 81%, respectively, compared to each of their controls. Thiamethoxam and spiromesifen did not provide effective control of secondary infection. Elimination of external sources of inoculum before starting new plantings and rational use of insecticides to reduce secondary infection may contribute to better disease management of tomato crops. |
