Tobacco mosaic of tomatoes can contribute to infection by other infections. Mixed diseases lead to a sting of tomatoes, which leads to weakening of the stems (the bushes break and dry).
Prevention
Prevention of tomato tobacco mosaic helps to avoid long-term treatment of the crop and prevent crop destruction. Preventive work includes treating an already healthy shrub, seedlings and preparing seeds that are planted in fertilized soil.
