Abstract:

In 1961, climatic conditions were entirely different from those of the preceding years. The warm and dry summer impeded the spread of rice blast disease. The preceding years, 1959 and 1960, were characterized not only by strong attacks by the mold, favored by meteorological conditions of high humidity and below normal temperatures, but also by faulty cultural practices excessive use of nitrogen fertilizer.
