Efficacy of fungicide seed dressings, foliar sprays, and moderately resistant cultivars alone or in combination for control of the wilt and root rot (WRR) complex of chickpeas was studied in fields with a history of high incidence (≥80%) of the disease. The efficacy of treatments was assessed by their influence on the epidemic development of the disease. Most epidemics of the WRR complex in the treated and control plots could be linearized best by the logistic transformation. Seed dressings with each of captan, captafol, thiram, benomyl, triadimenol and the mixtures of benomyl with captan, captafol, or thiram; thiabendazole with captan or captafol; and captafol with carboxin, triforine, thiophanate-methyl + maneb, or triadimenol + T1M-5107 + fuberidazol significantly increased seedling emergence of the moderately resistant cultivars PV-24 and PV-25 but not of the very susceptible P-2245 in 1980–1981 trials. Some fungicide seed dressings significantly delayed early development of epidemics for cultivars PV-24 and PV-25, but none, except triadimenol for cultivar P-2245, significantly decreased either the rate of disease increase or the final incidence of dead plants.
