The trials included 25 ‘Manzanilla’ and 12 ‘Arauco’ trees, with less than 50% of affected branches, at Aimogasta and El Tala. Treatments were: solarization (SOL), solarization + Trichoderma (SOL+TRI), solarization + organic matter (SOL + OM) and control (C). Disease severities were recorded during 2.5 and 1.5 years, respectively. For soil solarization, a transparent polyethylene of 100 µm was placed around each tree for 3 months. Before placing the plastic and one year later, soil samples were taken to determine the initial amount of microsclerotia per gram of soil (ID). Solarized plots reached maximum 51°C and control plots 40°C. Initial ID values were 2.52 to 1.84 and 1.23 to 2.13 after one year. The major decreases were obtained for SOL+TRI (0.08) and SOL. Controls did not increase ID at El Tala but it decreased at Aimogasta. All treatments decreased disease severities but there were no differences among treatments. Overall, disease severities decreased from 19 to 8% and 34 to 5% at both places. There were significant differences among plants (replicates) within each treatment. Results may have been influenced by fungus pathogenecity, inoculum distribution and density, edaphic factors, soil solarization efficiency and natural recovery phenomenon.
