Management of Ascochyta Blight of Chickpea Through Integration of Host Plant Tolerance and Foliar Spraying of Chlorothalonil
Year: 1990
Type: article
Abstract: A field trial was conducted for three seasons (1982/83, 1983/84, and 1985/86) at Tel Hadya, Syria, to evaluate effect of foliar spraying of chlorothalonil (Bravo 500) on Ascochyta blight severity and yield in a blight tolerant Kabuli chickpea cultivar ILC 482. One spray during the vegetative stage (VS) significantly reduced blight severity on leaves and stems in some seasons as compared to nonsprayed plots. Two sprays, one each during the VS and reproductive stage (RS) or both in RS signifi-cantly reduced blight severity on leaves, stems and pods and also increased yield in some seasons. Two sprays of chlorothalonil, one each during the seedling and early podding stages on an average of two seasons gave the highest cost-benefit ratio of 1:5 for controlling Ascochyta blight.
