GONZALEZ-ESTRADA, R.R. et al. In vitro evaluation of non-conventional chemicals for Penicillium citrinum control. Polibotánica [online]. 2020, n.49, pp.161-172.  Epub June 20, 2020. ISSN 1405-2768.  https://doi.org/10.18387/polibotanica.49.11.

Garlic (Allium sativum L.), is a crop that is exposed to the attack by important pathogens of the genus Penicillium causing significant economic losses. In this study, P. citrinum was isolated and identified by molecular tools. The antifungal capacity of hydrogen peroxide, SP, BS and chitosan treatments applied individually (mycelial growth and germination) at different concentrations as well as their combinations (taking into account the results of the individual application) for controlling in vitro of P. citrinum in terms of mycelial growth, sporulation and germination. The application of 0.5% H2O2, 3% SB and 1% chitosan were effective in inhibiting the development of the pathogen (100%). Synergistic effects of the treatments were observed when they were applied in combination with chitosan at low concentration (0.05%). Thus, the treatments evaluated in this study can be a viable and eco-friendly alternative for controlling P. citrinum in garlic.
