摘要：
The effect of salicylic acid (SA) on systemic resistance of cacao to Phytophthora palmivora was investigated using two clones, ICS 1 and IMC 67. The number of lesions per leaf were significantly reduced (P<0.05) in salicylic acid treated plants compared to those in the control. In addition, lesion area and the percentage of leaf area infected with P. palmivora were significantly reduced after salicylic acid treatment. Seed treatment, plant spray and soil drench induced systemic resistance in cacao, with seed treatment being most effective. While resistance was induced in both IMC 67 and ICS 1, the former had a comparatively better performance. These results indicate that SA induces systemic resistance in cacao and should be considered as a potential chemical for the control of P. palmivora.
