Management options readily available to farmers include keeping fields and surrounding areas free of weeds and volunteer plants (alternative hosts for viruses and their vectors); ensuring old crops are completely destroyed after harvest to remove sources of infection; growing seedlings (tomato and chili) in net cages thatexclude virus-vectoring insects until the seedlings are transplanted to the field; and inspecting the crop regularly after transplanting and removing (roguing) plants showing virus disease symptoms as soon as they are seen (to remove sources of infection for spread
within the field). Insect traps or insecticides can also be used to control vector populations, but must be applied before virus disease symptoms first appear in the field, which emphasizes the
importance of monitoring.
