In the field, eggplants are frequently attacked by Alternaria porri f. sp. solani, Botrytis cinerea and Phytophthora parasitica pathogens, which diminishes yield in quantitative terms and depreciates qualitatively. For the control of these pathogens three variants of fungicide treatments with different active ingredients were tested: chlorotalonil 500 g/l, pyraclostrobin 5% + metiram 55%, metiram 80%, iprovalicarb 8.4% + Cu oxychloride 40.6%, azoxystrobin 200 g/l + diphenoconazole 125 g/l. The best efficacy was obtained at variant 2 with the following schedule of treatments: treatment 1 - pyraclostrobin 5% + metiram 55% - 0.2%; treatment 2 - iprovalicarb 8.4% + Cu oxychloride 40.6% - 0.2%; treatment 3 - pyraclostrobin 5% + metiram 55% - 0.2%; treatment 4 - iprovalicarb 8.4% + Cu oxychloride 40.6% - 0.2%; treatment 5 - azoxystrobin 200 g/l + diphenoconazole 125 g/l - 0.1%; treatment 6 - pyraclostrobin 5% + metiram 55% - 0.2%. In this variant, the average efficacy was 85.5% and the yield 39.7 t/ha (123.17%) compared to 31.8 t/ha in the untreated control variant.
