  abstract = {The pitch canker, caused by the fungus Fusarium circinatum, is a disease under quarantine measures affecting Pinus spp. and Pseudotsuga menziesii worldwide. Characterized by the formation of large resinous cankers that girdle shoots, branches, and trunks, leads to the death of the host. To date, there are no means for the control of the pitch canker and, with the growing need to reduce the use of fungicides, another approaches must be studied. A method for the control of phytopathogenic diseases is the enhancement of host resistance, through pre-treatment of seedlings with chemicals or biologically derived compounds that stimulate defense responses. Phosphite (Phi) is an inorganic salt with the capability of inducing host resistance and presents an approach more environmentally friendly. In this study, the ability of potassium phosphite (KPhi) in delaying the pitch canker symptom development, as well as its effects in fungal growth, were studied at different concentrations. In a first phase, F. circinatum colonies were grown in PDA medium supplemented with Phi (0\,\%, 1\,\% and 4\,\%) to evaluation in the radial growth of the fungus. Posteriorly, were studied the effects of foliar application of Phi (0\,\%, 1\,\% and 4\,\%) in Pinus radiata seedlings, inoculated and non-inoculated. Survival and physiological performance (water potential, gas exchange and photochemical performance, pigments, lipid peroxidation, electrolyte leakage, proline and carbohydrates) were assessed. Results showed that Phi application delayed disease symptoms in a dose dependent manner similarly to what was observed in mycelial growth inhibition during in vitro assays. Physiological alterations in proline, carbohydrates, lipid peroxidation and gas exchange parameters were observed. Thus, Phi application presents a potential viable alternative to the management of the pitch canker disease.},
