Effects of Fungicide and Acetylsalicylic Acid Treatments on Qualitative and Quantitative Tomato Production

By stimulating the plant defense system using acetylsalicylic acid, there were studied various physiological parameters and productivity of tomato crop in the field, compared to a tomato crop treated with systemic fungicides and a sustainable culture treated with CuSO sub(4) (Bordeaux) mixture. Experimental crop was made up of two tomato varieties, the Sibiu local population and Buzau 50, both with undetermined growth and the used treatments were produced from: a systemic fungicides based mancozeb (60%) and dimetomorph (9%), contact fungicides - a mixture of CuSO sub(4) (Bordeaux mixture) and acetylsalicylic acid. Thereby, it resulted six experimental variants located in three repetitions. Regular observations were made in the field, on the growth and development of vegetative organs, of inflorescences and fruits, quality and quantity production of tomatoes, depending on the variety and the used treatment. There were found significant differences in experimental physiology tomato crops. Buzau 50 variety crop, treated with aspirin significant increases number of leaves, flowers and fruits. Crop productivity of both tomato varieties treated with aspirin was significantly increased. The groups treated with aspirin had significantly higher production compared to groups treated with fungicide. Aspirin generates a normal growth and resistance to the fungal pathogens for tomatoes.
