As difficult as blights are to manage in tomatoes, viral diseases are far worse. This is because there are no effective products to stop their spread. To make matters even more challenging, virus infection is most often the work of sap sucking insects, such as aphids, thrips, and leafhoppers, that vector diseases. Insecticides to stop these insects provide limited results, often after insect feeding has already enabled virus spread to plants.
