Relevance. Climatic factors of Primorsky Region make the most favorable conditions for developing of a diseases of vegetable crops. In such conditions leaves surfaces of the plants are defeated with the phytopathogens from Phytophthora, Alternaria, Septoria and Xanthomonas genus. Materials and methods. In the years 2016, 2017 some research on determination of the effectiveness of protective activities for the diseases control of tomatoes in the open field were taken in the Primorskaya Vegetable experimental station. Some activity was carried out with the sort of tomatoes Odissey in the coastal zone of Primorsky Region in the conditions of the monsoon climate with annual rainfall 700-800 mm, greater part of which falls in the summer season. Fungicides Acrobat MT, Orvego, Cignum and Skor were chosen for studying.

Two next cultivations were carried out with the intervals of 14-16 days according to the weather conditions. Results. At protecting from Alternaria (79.4%) the greatest biological effectiveness was shown by the fungicide Cignum. The biggest tomato crop productivity was also reached thank to cultivation with this fungicide: the crop raising of tomato commercial fruit was 15.2 t/h or 70.4% by comparison with the control version.
