The experiment, which aimed at controlling the pathogens that attack the summer-autumn tomato crops, included 5 variants. There were applied 5 treatments correlated with climatic factors. During the vegetation period we observed the appearance of the pathogens Xanthomonas vesicatoria , Alternaria solani , Phytophthora infestans , Colletotrichum coccodes and Phytophthora parasitica. The evaluation of efficacy of the variants was made in correlation with degree of attack (on the foliage) and frequency of attack (on the fruit) of the pathogens, and the economic efficiency was established according to the obtained yield. Experimental variants I (treatments: 1. Dithane M 45 0.2% + Champ 77 WG 0.3%; 2. Dithane M 45 0.2% + Cabrio Top 0.2%; 3. Melody Compact 49 WG 0.2%; 4. Melody Compact 49 WG 0.2%; 5. Melody Compact 49 WG 0.2% + Cabrio Top 0.2%) and III (treatments: 1.Polyram DF 0.2% + Champ 77 WG 0.3%; 2. Polyram DF 0.2% + Cabrio Top 0.2%; 3. Ridomil Gold Plus 42.5 WP 0.3%; 4. Ridomil Gold Plus 42.5 WP 0.3%;5. Ridomil Gold Plus 42.5 WP 0.3% + Cabrio Top 0.2%) gave the highest profit (I-13,129.46 lei and III-12,734.78 lei/1000sq.m.).
