Abstract: 

The experiment was carried out in the governorate of Tartous, the village of Karto in the autumn of 2022, where the tomatoes (Dana hybrid) was treated with the cucumber mosaic virus and without it within the plastic house with the SALSICO compound spraying on the plants and adding with irrigation water with two concentrations: 3 and 6 ml/l, in addition to two treatments of the infected control not treated with the SALSICO compound and the healthy control not treated with the SALSICO compound, to study the indicators of vegetative growth and production, which were plant height, leaf surface area, the amount of total chlorophyll in the leaves and production in the experimental plants. The results showed that spray treatments were superior in average plant height, leaf surface area, total chlorophyll, and fruit weight over irrigation treatments at the same concentrations, with significant differences in tomato plants infected and uninfected with the cucumber mosaic virus compared to the healthy and infected control, and the highest average plant height, leaf surface area, total chlorophyll, and fruit weight were recorded in the plants uninfected and treated with the SALSICO compound in the spray treatment with a concentration of 6 ml/L, it reached (2.39 m/plant, 14,880 cm2/plant, 1,111 mg/g, 5.95 kg/plant) respectively, and with an increase rate of (47.53, 38.80, 28.43, and 44.76)%, respectively, compared to the healthy control. The results showed the effectiveness of the SALSICO compound at concentrations of 3 and 6 ml/l and with two treatment methods (spraying, irrigation) in stimulating vegetative and fruit growth and increasing productivity in protected tomato plants in the presence and absence of viral infection.

Keywords: SALSICO compound (sugar alcohols and salicylic acid), protected tomatoes, vegetative growth, production, cucumber mosaic virus.
