Field Testing of Potential New Fungicides for Control of Phytophthora Root and Crown Rot of Chile Pepper
MetadataShow full item record
AbstractRoot and crown rot and blight of chile peppers is caused by the soil -borne plant pathogenic fungus Phytophthora capsici. The root and crown rot phases of the disease are favored by saturated soil conditions, while rainfall accompanied by wind helps initiate the blight phase. The purpose of this study was to evaluate potential new fungicides for disease control. Some treatments of Aliette and Fluazinam as well as Ridomil tended to reduce the incidence of disease in this trial. However, the high variability in disease incidence among the replicates of each treatment prevented the demonstration of statistically significant differences in this study. We hope to repeat this trial next year and achieve more definite results.
