LINS, Severina Rodrigues de Oliveira et al. Alternative control of stem-end rot in mango. Summa phytopathol. [online]. 2011, vol.37, n.3, pp.121-126. ISSN 0100-5405.  https://doi.org/10.1590/S0100-54052011000300007.

The aim of this study was to evaluate the effect of alternative products in mango sleeves inoculated challenged with Lasiodiplodia theobromae and its influence on the mycelial growth of the pathogen in vitro. Mangoes were treated with: potassium phosphate (50, 100 and 150), hidroxidobenzóico acid (5, 10 and 15), calcium chloride (0.13, 0.26 and 0.39) (in mmol), ultraviolet light ( 10, 20 and 30 min.), extracts of garlic, melons of the Caetano, bark of mango (25, 50 and 75%) and water (control). The design was a split plot. 106 con./mL was inoculated immediately after each treatment (T1), twelve hours after (T2) and twenty-four hours after (T3). In T1, the best treatments were PO (50 mmol) and CC (0.13 mmol). T2 in there were CC (0.13 mmol), AH (5 mmol), EA (25%) and FP (100 mmol). In T3 there was no difference between treatments. In vitro treatments were mixed into the culture medium. After solidification it was placed in the center of each plate, structures of the phythopathogen. The model was in DIC with 6 replications. After 48 hours it was measured the diameter of the colony. The best treatments were FP (100 and 150 mmol), ECM (50 and 75%) and EA (50%).
