Tomato (Lycopersicon esculentum L.) is a widely grown vegetable in the entire world and Latvia as well. Tomato fruits are characterized by a good nutritional profile and can be consumed fresh or processed. One of the biggest threats of tomato growers is the diseases that significantly reduce the amount of yield. Tomato can be infected by pathogens of different genera – Pythium, Rhizoctonia, Fusarium, Phytophthora, Septoria, Alternaria, Oidium, Leveillula, Colletotrichum, Verticillium, and Botrytis. No research on tomato diseases has been carried out in Latvia. The present research aimed to diagnose tomato diseases and identify their causal agents. The study was carried out on 6 farms in the central part of Latvia in 2021. The dominant diseases were different leaf spots caused by the genera Alternaria, Botrytis, and Cladosporium. Diseases of tomato fruits were caused by Alternaria spp. and Botrytis spp. The research should be continued, as many questions remain unclear.
