Chemical control stem rot caused by Lasiodiplodia theobromae on mangoes fruits

This work aimed to evaluate the difenoconazole fungicide efficiency to control stem rot in mango fruits cv. Tommy Atkins. The experiment was carried out in a randomized blocks design, with four repetitions of nine plants. The treatments was compound by the respective fungicides and doses: difenoconazole (75; 100; 125 L.ha-1), azoxystrobin (80 g.ha-1), including 0,05% of nonylphenol ethoxylate, chlorothalonil (1.237,5 kg.ha-1), propiconazole (100 mL.ha-1), and control, without fungicide application. Six fungicide applications were realized, with 15 days interval, with the first at the panicles blooming. Twenty five fruits per plot were collected for evaluation, being stored under ambient conditions in plastic containers for 15 days. There was no significant difference between the tested doses, however all the treatments with fungicide differed from the control treatment. The difenoconazole was efficient in all levels, it can be recommended to phytopathological management of this disease.
